There is no synchronization or any other form of thread safety. So class can't be used in a multi threaded environment safely.

Currently there also is quite a lot of deprecated functionality, so perhaps better to get that out of the way first before fixing something that is going to be changed/removed.

There is no synchronization happening at all. Everybody can peek and poke in this collections,which can lead to race problems, but also to strange situations (e.g. an entity without a location).

I think it is best to return a copy of the list instead of returning the actual list.

The method should return a copy of the collections, not a readonly wrapper. If the readonly wrapper is returned, a user of this wrapper could observe unexpected change happening inside this list, leading to race problems.

The CustomAggregatingEnricher can be used with groups, to automatically aggregate the members of the group. However, it does not take into account existing members - only members that are added and removed after the enricher is associated with the group.

When the CustomAggregatingEnricher is registered, it should lookup the members of the group and subscribe to the given sensor for them.

It would also be nice if this contract was more explicit. The code for notifying of "producers" being added/removed is buried away in AbstractGroup. When looking at the CustomAggregatingEnricher, the code at first looks like black-magic. I suggest moving the notifications into the CustomAggregatingEnricher (or its super-class) explicitly by subscribing to member added/removed.

We should set up an account using the free open-source access tier of CloudBees, to provide community visibility into CI for building/testing Brooklyn.

The default clean patterns (brooklyn_.log_ and stacktrace.log) are overridden. As a result, files are no longer cleaned.

When running brooklyn I get this annoying warning:

Management is currently only possible at the instance where Brooklyn is launched.

We'd like to be able to start Brooklyn nodes remotely (1, or 2 for resilience) in each datacenter location where Brooklyn is running, and have them share information. Each entity should be mastered at one management node, as close to the entity as possible, with failover. It could be possible to manage entities at the same node as the process.

This would allow for resilience and scalability, as well as more efficient policy execution.

we list activities (tasks) but the tree structure kept in the code (where a task on a parent launches tasks on children) is not apparent; being able to navigate task hierarchies would be very handy

if user asks to deploy a Whirr cluster to localhost we should configure a jclouds-byon-localhost target automatically. easily done adding a startInLocation(LocalhostMachineProvisioningLocation) method to WhirrCluster and following code at https://github.com/jclouds/jclouds/blob/master/apis/byon/src/test/java/org/jclouds/byon/BYONComputeServiceLiveTest.java.

If a brooklyn entity loses connection to the physical-thing-being-management, it should automatically re-connect if the network/thing comes back up again. For example, if we the internet connection goes down for a few seconds between Brooklyn and a Tomcat server, we should re-establish connection to the Tomcat server and continue polling it (over jmx).

Entities poll their sensor values by a variety of mechanisms: jmx, http, etc. Let's consider jmx (but this should equally apply to other mechanisms as well). We poll jmx attributes/operations periodically. If the network goes down temporarily, we lose connection and we neer automatically re-establish the connection. Therefore, the entity's sensors never again refresh.

Some useful places in the code to look include:
JmxHelper
JmxNotificationAdapter
JmxAttributeAdapter

Add a RabbitMQ messaging entity. This should include support for broker clusters and failover, and perhaps deployable erlang plugins. The existing MySQL entity should be useful as a template for installation of native pre-built siftware, and the rest of the sensors and effectors should follow the existing messaging entity patterns.

Running the broker works fine on localhost but I get the following exception when running on AWS:

The getPolicies returns a readonly wrapper that is backed up by the real policy set.

So if a user would use this collection, the collection maybe change while he is working on it. This can lead to all kinds of exceptions.

So instead of returning a readonly wrapper, return a copy.

• Write an example/demo application that uses JMS with a broker (preferably Apache Qpid) and demonstrates scaling clients based on queue depth.
• Document the example and the use of the messaging entities

When running a brooklyn example like ./demo-web-cluster.sh from examples/simple-web-cluster you get ssh problems:

2012-05-07 14:26:51,450 INFO << (cosmin@localhost:22) error acquiring {hostAndPort=localhost:22, user=cosmin, ssh=1506268053, password=null, privateKeyFile=null, privateKey=xxxxxx, connectTimeout=0, sessionTimeout=0} (attempt 1 of 4): Exhausted available authentication methods

There is already a comment that talks about this and a fix here so this will probably get resolved soon.

As a workaround in the meanwhile, you can update the CLASSPATH environment variable before running the example:

export CLASSPATH=~/.m2/repository/org/bouncycastle/bcprov-jdk16/1.46/bcprov-jdk16-1.46.jar:~/.m2/repository/io/brooklyn/brooklyn-all/0.4.0-SNAPSHOT/brooklyn-all-0.4.0-SNAPSHOT.jar

Brooklyn fails to compile in Eclipse with the GroovyEclipseBug shown below.

This is with org.codehause.groovy.eclipse version 2.6.0, in Eclipse Indigo Service Release 2.

The method:
private static T getMandatoryVal(Map<String,?> map, String key, Class clazz)
is delcared in SshjTool.

The class reporting the compile error is EffectorSayHiTest.groovy, at line 0.

General error during class generation: Cannot find type variable on method declaring element private static T getMandatoryVal(Map<java.lang.String,?>, java.lang.String, Class)

We'd like on the download page to offer a tar.gz containing the jars and a start script that uses Java6 -cp lib/*.jar syntax.

A maven assembly task can build the artifact and should be part of CI.

The examples should be updated so that they can use this (if a BROOKLYN_HOME var is set?) as well as the all jar from a local maven repo.

The docs for download and examples should be updated to reflect this.

With CloudFoundry (#15) and OpenShift (and more on the way), we need a clean way in Brooklyn to support deploying entities to locations which may not be known (and which shouldn't be in classpath) when the entities themselves were made.

There are at least two parts to this:

(1) the CommandLineLocations (in core) should have an extension mechanism -- whereby e.g. it can construct a CloudFoundryLocation at runtime given a string "cloudfoundry", if the cloudfoundry project is present (without have cloudfoundry deps/refs in core itself)

(2) specific Entity or EntityFactory implementations interfaces (eg WebClusterFactory) should have a way that they can, if desired, allow downstream projects to supply additional implementations or drivers (eg cloudfoundry project can supply a WebClusterFabric)

JSch has been replaced by sshj, so it can be removed

There are a number of problems with how people download and use the examples, in order for them to be familiar and usable.

Cosmin has suggested that we get rid of the distribution directory which is generated for each examples, and remove the scripts, and instead use a short text file in the root containing instructions for running from plain vanilla jars (and minimal additional dependencies).

Let's do that, and update the following which I've observed:

• The docs/ for don't work, as they leave out the step for downloading and setting up brooklyn !
• download instructions should describe where to get release repo, and where to get the dist TGZ
  http://ccweb.cloudsoftcorp.com/maven/libs-release-local/io/brooklyn/brooklyn-dist/0.4.0-M1/brooklyn-dist-0.4.0-M1-dist.tar.gz
• download links are broken for releases ("snapshot" is hardcoded).
• we should use "cloudsoft-{release,snapshot}" repos (for clarity when working with examples) rather than "lib-*-local"
• "dist" artifacts should put things into a directory called brooklyn-$VERSION e.g. brooklyn-0.4.0-M1 (not brooklyn)
• why refer to "dist" twice in the artifact basename -- ie "brooklyn-dist-VERSION-dist" ... prefer "brooklyn-VERSION-dist"
  should have a README (maybe containing a one sentence intro, pointer to website, and pointer to examples repo) and a
  LICENSE.TXT in the root dir of the dist

A generic command-line tool which could take a groovy deployment script (or JSON representation as per #3) would be very helpful, meaning people don't need to recompile anything to make a change.

This could also standardise the --port N option, and location arguments, used in the examples.

The examples and the documentation should be updated to use this. This could also build on #1.

grails 1.7 is long-in-the-tooth, and we've done some hacks to make it work with groovy 1.8.

switching to grails 2.0 would solve this.

or could move away from grails if people prefer? it makes some things easier but some things harder.

This is possibly related to issue #143. When I try to run the WebClusterExample from simple-web-cluster I get an IOException that looks to be related to the JBoss7Server entity.

UPDATE: Looks like the GlobalWebFabricExample is also affected by this

Apart from the exception everything seems to be working fine.

The only things that looks worrying in the web console is the fact that NGINX has been started and then restarted:

DynamicWebAppCluster:gICn   start    2012-05-31 10:37:48    2012-05-31 10:37:51 Ended normally
JBoss7Server:B9lL   start    2012-05-31 10:37:48    2012-05-31 10:37:51 Ended normally
NginxController:W86T    restart 2012-05-31 10:38:18 2012-05-31 10:38:18 Ended normally
NginxController:W86T    start   2012-05-31 10:37:48 2012-05-31 10:38:18 Ended normally
WebApp cluster  start    2012-05-31 10:37:48    2012-05-31 10:38:18 Ended normally

Here is the full output I get when running the example:

• delete EntityLocal.getConfigKeys(), EntityLocal.getSensors() and EntityLocal.getEffectors().
  These methods are already on EntityClass
• rename EntityClass to EntityType.
• clean up the javadoc and the comments.
• it will give an immutable snapshot of the set of sensors, effectors and config keys that an entity has. This describes just the types, rather than the values.
  If someone adds a new sensor to the entity instance on-the-fly, then a subsequent call to entity.getEntityType().getSensors() will include that change.
  (this is a change in semantics: previously it did not include sensors added on-the-fly).

When I stop brooklyn after running the hadoop.sh example script (that in turn starts brooklyn.extras.whirr.WhirrHadoopExample) I get this warning message:

2012-05-31 13:13:13,901 INFO  Finished running stop phase scripts on all cluster instances

UPDATE: It looks like the hadoop processes don't shut down properly when stopping brooklyn (if deploying to localhost). If deploying to AWS on the other hand, I still get the warnings but the VMs get shutdown normally.

We need more longevity and stress tests in Brooklyn.

Example test
As a first test to write, how about:

• create a web-cluster (nginx + as7)
• a resize policy to scale-out and scale-back the cluster (from 1 to 4 app-servers)
• an "enricher" to publish a pseudo-load sensor that varies sinusoidally over time so that the resizing will be triggered every couple of minutes.
• a scheduled executor for sending http requests, to confirm the web-app is always accessible via the nginx node

We'd programmatically monitor:

• scale up/down keep happening (ps aux | grep jboss returns different pids over time)
• memory usage of brooklyn (jmap -histo )
• grep -E "SEVERE|ERROR|WARN|Exception|Error" brooklyn.log
  We should strive for that to be empty!

If watching manually, we'd also run jconsole.

We'd first run this on localhost. Then we'd run it with a fixed set of IPs if we have access to a few spare servers.

Test structure
As a first step, we can write a script that launches both brooklyn and a "monitoring process" to do the above checks. Groovy is probably a good bet for the monitoring process code, because it is scripting.

As a future step, we would beg a server (or few) for running this regularly. We'd have jenkins run a testng test for it (that called the scripts?). Jenkins would run it every day, and the test would run for 23 hours.

Improving test coverage
There are various other things I'd love to be covered in the longevity tests. These include:

• brooklyn web-console
• more entity types
• more policies / enrichers
• entities that query sensor-values using jmx, http, and scripts

We've just made a 0.4.0-M1, as something of an experiment. Here is the general process:

• change version (using usage/scripts/change-version.sh)
• mvn clean all
• push to a branch
• mvn deploy (with appropriate settings.xml)
• update docs (as per docs/_script/help.txt)
• update examples (copying examples to brooklyncentral/brooklyn-examples project, modifying pom.xml, and pushing)
  • remove relativePath entry from pom.xml (possibly unnecessary?)
  • add repositories section, adding lib-release-local (for now)
  • make sure bin/*.sh files are checked in (not gitignored)

There are some repo issues to resolve (which will be the next issue I create), and then we should document exactly what the process is, and put it in the documentation. But wanted to capture (a) knowledge so far, and (b) need to do this.

A maven archetype for creating a new brooklyn project, with the right dependencies (and optionally groovy compilation support), would be very useful and fairly straightforward.

When running a brooklyn web cluster app at the command line, I did cntrl-c. It took a few minutes (during which it was still starting/installing JBoss), and then I got the exception below.

(Note that the code like 1 * TimeUnit.SECONDS is possible due to fancy meta-programming in TimeExtras; it generates groovy Duration instances as long as TimeExtras has been class-loaded first).

I'm confident that the JBoss7Server code is fine, because it works at other times.

I wonder whether this could be due to compilation happening in the background... I had Eclipse open so it's conceivable that it might have re-compiled some of the .class files while the brooklyn app was running. However, that's just speculation. I saw this same error once before when doing cntrl-c, but that time I'd done a mvn clean install while the brooklyn app was still running so I'd put it down to that...

If it is just caused by re-compilation then it's annoying for developers, but also very low-priority...

1. When running the subscribe.sh script, the process exits after a short time. It would be more convenient for it to block so that I have enough time to start the publish.sh script.
2. When running both subscribe.sh or publish.sh I get some annoying log4j warnings:

log4j:WARN No appenders could be found for logger (org.apache.qpid.client.AMQConnection).
log4j:WARN Please initialize the log4j system properly.

On restarting brooklyn, it would be very useful to re-bind to existing entities. A big part of that is to rebind to the existing machine-locations that they are running in.

For jclouds location, that requires a "rebind" method to (re)generate an appropriate SshMachineLocation. This would also allow subsequent calls to jcloudsLocation.release(machine).

The rebind would take:

• id: the jclouds VM id, e.g. "eu-west-1/i-5504f21d"
• hostname: the public hostname or IP of the machine, e.g. "ec2-176-34-93-58.eu-west-1.compute.amazonaws.com"
• userName: the username for ssh'ing into the machine

The other properties (e.g. ssh private-key) would be assumed to match those defined in the JcloudsLocation configuration.

As a future enhancement, that could also be configurable (e.g. so that a VM started completely externally could then be bound into Brooklyn, even if it wasn't started by Brooklyn/jclouds).

When providing the "--locations loc1 loc2 loc3" argument like this, it looks like only the first location is used.

This is related to how git-like-cli works. It's not happy for some reason with accepting more than one argument for an option. Not sure if we can get it to do that, but it's not obvios form what I've seen in the examples provided.

We currently expose a web console but not a web API. A web RESTful API would allow easy programmatic management and access to sensor data in a language neutral way.

A JSON/XML representation of applications, and an API capability to deploy these, would be a powerful extension making Brooklyn easier for people to consume and also helping with language neutrality.

An "at-rest" representation of the same would be useful for persisting to disk and likely helpful for issue #2.

I saw the weird exception below when running a web-cluster (nginx + jboss7), with an averaging enricher and custom pseudo-load attribute-sensor generator.

The exception happened only 4 times during an overnight run, where the sensor was updating every 500ms. So I believe it successfully passed through this call-path thousands of other times!

Proposal in brief
Brooklyn currently uses jsch [1,2]. I propose changing this to use sshj [3] instead. This will be a straight swap of the brooklyn jsch code for a new sshj-based implementation.

This switch should be completely transparent to users and entity-authors (except for getting more reliability and speed).

Justification
Problems with jsch include it returning exit codes of -1, and it losing some of the characters from long commands that you ask it to execute. In the currently brooklyn code base to work around this, we have a horrible sleep between command executions and some synchronization to avoid concurrent executions - very unpleasant, but without it some example apps frequently failed.

jclouds went through the same refactoring in July 2011 [4].

Details
I see a few options.

1. Swap brooklyn jsch implementation for a new sshj implementation.
2. Do all calls through jclouds location objects (i.e. ComputeService.runScriptOnNode)
3. Instantiate a org.jclouds.ssh.SshClient ourselves (using its implementation SshjSshClient)
   This is probably impractical because it relies on guice for setting package-private fields.

I think option 1 is definitely worth doing as it requires the fewest changes in the rest of the brooklyn code base. Hopefully it won't be hard, particularly with the existing jclouds code for reference.

For option 2, that is a good thing to aim for longer-term in various places. Calls currently pass through SshMachineLocation.run. For machine instances created through jclouds, we should be able to use ComputeService.runScriptOnNode instead.

[4] http://code.google.com/p/jclouds/issues/detail?id=637

being able to configure logging levels and make the logs available in the web console would make debugging much easier. especially if we can see SSH i/o attached to a task (say, for when mysql fails because a library isn't available)

It looks like the Tomcat Server and JBoss AS6 Are still using OldJmxSensorAdapter and brooklyn.entity.basic.legacy.JavaApp.

They should use the newer classes as is done in JBoss7Server.

Things to do:

• refactor those entities to use the newer code (and thus take advantage of jmx reconnect etc).
• deprecate the old classes.
• ensure any useful tests/code is scavenged from there.

CustomAggregatingEnricherTest fails from time to time making build problematic.

Brooklyn would make an ideal host for CloudFoundry services - could you consider adding support for this?

CloudFoundry consists of a number of core services - cloud controller, health manager, router and DEA. A typical system would need at least one of every one of these. DEAs are the hosts for the applications, so as more applications are deployed, with more instances, then it becomes advantageous to add more DEAs to spread the load. Similar for routers. For small installations, services can be colocated (so one of every node type can run on a single machine).

CloudFoundry also has support for "services" - databases, message queues, etc. that applications can call on. So CloudFoundry has a "mysql" module which connects to a MySQL instance. These could also be scaled out, so that there are multiple MySQL instances.

currently the id_rsa / id_dsa keys specified for brooklyn must not have any passphrase set.
it would be nice to support passphrases, allowing them to be specified:

• in ~/.brooklyn/brooklyn.properties
• as an environment variable
• as a java system property

BrooklynProperties makes this straightforward. syntax would be comparable to how private-keys are defined (perhaps brooklyn.jclouds.localhost.private-key-passphrase), see CredentialsFromEnv.

Currently the retrieval of memory related information looks like this:

jmxAdapter.objectName(ManagementFactory.MEMORY_MXBEAN_NAME).with {
attribute("HeapMemoryUsage").subscribe(UsesJavaMXBeans.USED_HEAP_MEMORY, { CompositeData m -> MemoryUsage.from(m)?.getUsed() });
attribute("HeapMemoryUsage").subscribe(UsesJavaMXBeans.INIT_HEAP_MEMORY, { CompositeData m -> MemoryUsage.from(m)?.getInit() });
attribute("HeapMemoryUsage").subscribe(UsesJavaMXBeans.COMMITTED_HEAP_MEMORY, { CompositeData m -> MemoryUsage.from(m)?.getCommitted() });
attribute("HeapMemoryUsage").subscribe(UsesJavaMXBeans.MAX_HEAP_MEMORY, { CompositeData m -> MemoryUsage.from(m)?.getMax() });
attribute("NonHeapMemoryUsage").subscribe(UsesJavaMXBeans.NON_HEAP_MEMORY_USAGE, { CompositeData m -> MemoryUsage.from(m)?.getUsed() });
}

This means that 5 times the same information is retrieved from the jmx server, only a different field is used. So it is very inefficient. All the sensors could share the same information and instead of 5 round trips, only 1 is needed.

Alex came up with the following suggestion:

attribute("HeadMemoryUsage").then( { MemoryUsage.from(it) }).with {
subscribe(MAX_HEAP_MEMORY, { it.getMax() });
subscribe(COMMITED_HEAD_MEM, { it.getCommitted() });
...
}

Every entity will get its own sensor registry, every sensor registry will gets a number of threads equal to the number of cpu's in the machine. So with 1000 entities and an 8 core machine we have 8000 threads, which vm's don't always like. If you are going to increase the number of entities.. well.. you get the problem; the approach isn't scalable.

The ManagementContext exposes an ExecutionContext submit scheduled task method, make use of this instead and remove the sensorregistry.scheduledexecutor.

After this refactoring is complete, there is no direct relation between the number of entities and the number of threads, which makes the system much better scalable (inside a single jvm).

A problem could be however with removing scheduled tasks for certain entities....

I've seen mysql not start, very very occasionally. I could do with some help/advice!

I suspect it is due to the way we are nohupping and running SSH:

nohup mysqld & echo $! > pid.txt

What we observe it that the pid.txt file is created but pid not running. There is no nohup.out and no indication of any problem in the log.

I wonder if it is related to the fact that we wait for ssh "termination" (in SshjTool eg ShellAction.create) by doing:

shell.join(TIMEOUT);
session.getExitStatus()

In particular we don't do session.join(TIMEOUT), which is advertised on the sshj API but not documented, so not sure.
But I suspect this is the cause of a difference in behaviour with command-line ssh, where:

ssh localhost 'nohup mysqld & echo $! > pid.txt ; exit 0'

Does not return (until you've manually killed mysqld in a separate process). Even though the shell has exitted and
returned the exit code, I suspect the session is kept open until std{in,out,err} are closed. In particular if we add redirects:

ssh localhost 'nohup mysqld > out 2> err < /dev/null & echo $! > pid.txt ; exit 0'

The process does return. (See http://stackoverflow.com/questions/29142 .)

Most tellingly, in the logs, when the mysqld problem happens, we do not get the usual messages about output going to nohup.out.
So what I think is happening is that the script is proceeding to exit and the ssh session closed, while nohup is still starting,
causing nohup itself to be killed before it has launched mysqld (ie before it has applied any nohupping).

Does this seem plausible?

If so I can see a few possible solutions:

• We just add a 'sleep 2' after any nohupped process

• We run: nohup bash -c 'mysqld & echo $! > pid.txt'
  (causing the script not to proceed until bash has launched nohup.
  pid.txt may not be available immediately but that's okay as the subsequent scripts are forgiving.
  but means users have to code carefully for background processes.)

• We add the session.join(TIMEOUT), with a small timeout, say 10s,
  and warn if the session isn't ended in that time (to preserve compatibility),
  and encourage developers to write the following in their scripts:

  nohup mysqld > out 2> err < /dev/null &

I repeat it's rare (only 1 documented case) but potentially problematic so I think we should address it.
I think prefer the last option -- can't see anything that would break, and moves us to a better model.

Could do however with a sanity check, or better ideas!

the web console collects sensor data, it would be nice to have an option to show a graph for a specific sensor and expose that as a widget, so you could e.g. embed it in your favourite dashboard

e.g. brooklyn.properties

perhaps remove the SpringSecurity since it appears to take a long time to start up

We've just made a 0.4.0-M1, as something of an experiment. Here is the general process:

When running the SingleWebServerExample or WebClusterDatabaseExample from simple-web-cluster I get a ConnectException. Apart from that, everything seems fine: console starts up, reports that JBoss7 ended normally, and the hello-world-webapp shows up at localhost:8080.

UPDATE: looks like the portable-cloudfoundry example is also affected by this same issue.

UPDATE: GlobalWebFabricExample is also affected.

UPDATE: brooklyn.extras.whirr.WebClusterWithHadoopExample is also affected.

This is the output I for SingleWebServerExample:

The update method does a synchronized on the targetHosts list. The targetHosts itself is a threadsafe list (since it is created using a Collections.synchronizedMap). But by calling synchronized the intrinsic lock of the targetHosts object is acquired, and this could be a completely different lock than the lock used by the Collections.synchronizedMap implementation.

So while the synchronized block is entered, there is no guarantee that another method can't call a put/remove operation on the map.

So the code is unclear at best, or otherwise broken. A typical example of sprinkling the code with synchronized to hope to get something threadsafe.

Solution? Don't know.. perhaps use a normal mutable collections for the targetHost, and always use explicit synchronization if some form of stable copy is needed. Otherwise perhaps make use of the concurrenthashmap
