Looking for docker platform
I want use this for container platform.
My tomcat running in docker environment.
Can you guide me how I can use this without rebuilding tomcat application (docker)
May be I can run this as a separate container and collect metrics from tomcat application (docker).
TomcatJdbcPoolExports initialization issue
If the metrics.war deployed first the TomcatJdbcPoolExports will be disabled ?

The issue is made by incompatibilities between newer Prometheus libs versions and older Tomcat versions.

Tomcat 6 died when use tomcat_exporter
Hi,
I have problems on Tomcat version 6.
When I insert your suggest filter tag in [ web.xml ] on Tomcat server and restart service, my tomcat server is unavailable to access. but in newer version such as 7 , 8 it work.!!
how can I do for this case?
thank you.
embed jars?
doing the following causes mvn package to create a .war that's probably excessive (API jars should be dropped) but is drop-in ready without any other .jars. is this the purpose of the message "all metrics are registered using the same class loader"?
Perhaps an alternate approach is to create an uber-jar with all the deps (and no .war) and add the servlet via the top level web.xml using <servlet-class>…

<groupId>javax.servlet</groupId>Delayed metrics
I deployed the Prometheus JMX Exporter and it has a delay option. Our applications generally spike on deployment and this option may be useful for filtering out those initial metrics. Does this tomcat exporter provide a similar option, or something that could be added? Thanks
Duplicate registration exception when there are multiple jdbc connections defined in tomcat with latest prometheus library
Latest prometheus client library (0.12.0) throws exception trying to register the same gauge more than once. Need to move the registration code outside of the loop.
prometheus 0.12.0 needs simpleclient_servlet_common
I guess the readme needs to be adopted.

Is this project still maintained?
Is this project still maintained?
I'm halfway through implementing my own and found this while looking into how to get the thread pool metrics from Tomcat.
I'm thinking of continuing with my own implementation using the Prometheus java client 1.x as well as some other features. Not really interested in the DB pools since HikariCP is superior and has it's own Prometheus exporter.
Add JMX Exporter features?
Hello,
I would like to know if you would be open to a contribution to add features from the https://github.com/prometheus/jmx_exporter into the actual exporter ?
What I have in mind:
- I don't want to expose an additional http port so I want to avoid the java agent approach of the jmx_exporter
- in the servlet filter add an optional parameter to point to a jmx_exporter configuration file on the file system that will add a JMX Collector io.prometheus.jmx.JMXCollector
Cheers,
Fabien
Contect deadline exceed (Get https://my_ip/metrics/: context deadline exceeded)
Hello ,
I configured the exporter in my centos 7 , i am able to see details from my browser.
But when i am adding below configuration in promethues, I am getting content deadline exceed error.
I tried to search on internet but didn't come with why i am getting this error, once surprise thing i found that in prometheus its's trying to get connect with https://myip:8080/metrics , while it should need to connect with http. I am attaching the screenshot of error and my configuration, please help me for get rid our from this.
My Prom Configuration :
scrape_configs:
-
job_name: support_ticket
static_configs:- targets: ['IP:9100']
-
job_name: java_monitoring
static_configs:- targets: ['IP:8080']
404 after deploying metrics.war
Downloaded jar files of the latest version, moved them to my /opt/tomcat/lib/ folder. Downloaded tomcat_exporter_servlet.war, renamed it to metrics.war, added it to webapps folder that has another application of mine running. http://host:8080/metrics returns 404. Checked my logs and there is nothing significant unlike the 404. How can i resolve this?!!
MaxActive attribute not found
Hello,
Using the exporter with tomcat 8.5.33 I get the exception:
javax.management.AttributeNotFoundException: No such attribute: MaxActive
When I look at the docs of the jdbc connectionpool it looks like the MaxActive attribute should still be there.
Can't see the metrics
Hi I am integrating Tomcat Exporter on one of my servers. I currently see such an error message.

Maybe TomcatMetricsServlet could have it's own CollectorRegistry?
Can help with a PR if needed.
A dashboard for this exporter?
Hi Guys,
Someone can tell me the avaiable dashboard for this exporter?
Tks so much.

Dependency conflicts: there are conflicting classes in several JAR pairs
Hi, by analyzing tomcat_exporter-master\client\pom.xml, I found a series of dependency conflicts between the libraries transitively introduced by org.apache.tomcat.embed:tomcat-embed-core:8.5.11 and org.apache.tomcat:tomcat-catalina:8.5.24. As the JVM only load the classes present first on the classpath and shadow the other duplicate ones with the same names. The dependency conflict problem brings high risks of "NoSuchMethodException" or "NoSuchMethodError" issues at runtime. The conflicting details are listed below. Maybe the solution is that upgrading org.apache.tomcat.embed:tomcat-embed-core from 8.5.11 to 8.5.24. Please notice that. Thanks!

Criação do contexto da aplicação no monitoramento do Pool de conexões do Datasource
Boa noite,
Realizei uma mudança no código adicionando o contexto da aplicação no monitoramento do Pool de conexões.
Caso achem interessante adicionar no aplicativo, posso enviar o código para vocês.
Só não consegui acertar os testes, não estou conseguindo simular esse comportamento sem o Tomcat.
Atenciosamente,
Rodrigo Cesar Perlin (Guina).
Whether it works on Windows server？
Session metrics have label host and context mixed up
Syntax issue in the output
Dear @team,
I trying to install the tomcat exporter. I installed the tomcat exporter with the latest release.
I found that there is some syntax issue in the output.
Tomcat Exporter Output:
Reference:
Below 2 Exporter outputs are standard exporter supported by Prometheus
Node Exporter Output
WMI Exporter Output
I found that there is an ',' at the labels in tomcat exporter. Due to this, I am unable to parse the syntax.
Oracle JDBC interceptor is not working
I configured my JDBC as follows:
<Resource name="jdbc/open_database_pooled"
auth="Container"
connectionFactoryClassName="oracle.jdbc.pool.OracleDataSource"
connectionPoolName="open_database_pooled"
defaultAutoCommit="false"
factory="oracle.ucp.jdbc.PoolDataSourceImpl"
global="jdbc/open_database_pooled"
inactiveConnectionTimeout="20"
maxPoolSize="50"
minPoolSize="10"
user="${db.user}"
password="secret"
url="${jdbc.url}"
type="oracle.ucp.jdbc.PoolDataSource"
validateConnectionOnBorrow="true"
sqlForValidateConnection="select 1 from DUAL"
jdbcInterceptors="nl.nlighten.prometheus.tomcat.TomcatJdbcInterceptor(logFailed=true,logSlow=true,threshold=1000,buckets=.01|.05|.1|1|10,slowQueryBuckets=1|10|30)"
driverClassName="oracle.jdbc.driver.OracleDriver"
defaultRowPrefetch="100000"/>But as you said in the code comment, it wont work. You wrote This interceptor will NOT work for any other connection pool (eg DBCP2)..
Do you have some hints for creating an Oracle JDBC interceptor?
