Because this is an unsigned plugin, it's not compatible with Grafana 8.

Edit: After setting this option in the grafana.ini

allow_loading_unsigned_plugins = checkmk-datasource

I get this error message:

Fetch error: 403 Forbidden Instantiating https://grafana.xxx.de:53000/public/plugins/checkmk-datasource/module.js Loading plugins/checkmk-datasource/module
Data Source Error

In case I configure a site with an old Check_MK version that has missing CORS settings I get this message in the GUI:

Could not read API response, make sure the URL you provided is correct.

The browser console shows this message:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at http://localhost/heute/check_mk/webapi.py?_username=undefined&_secret=undefined&output_format=json&action=get_all_hosts. (Reason: CORS header ‘Access-Control-Allow-Origin’ missing).

Is it possible to detect this specific situation (CORS header issue) and print out another error message?

Something like: Invalid URL or Check_MK version. You need to use at least Check_MK 1.5.0p16.

In case an API call fails it reports back a structure like this:

{"result": "Check_MK exception: Currently not supported with this Check_MK Edition", "result_code": 1}

Can we show the error messages of the result_code=1 responses to the use in the panel editor?

Hi,

it would be nice if the CheckMK Datasource would use the Grafana-Server as a Proxy for accessing the checkmk (f.e. like the ElasticSearch Datasource Plugin).

@cbmueller What do we need to do before we can submit this?

When using the plugin with the RAW edition, before plugin version 2.0 I could use multiple queries on different hosts in a single graph. Now, all data frames have the same name (e.g. "Input bandwidth" and "Output bandwidth", each repeated once for every host).

I hacked around this using the following:

--- a/src/DataSource.ts
+++ b/src/DataSource.ts
@@ -24,7 +24,7 @@ function buildMetricDataFrame(response: any, query: MyQuery) {
   const frame = new MutableDataFrame({
     refId: query.refId,
     fields: [{ name: 'Time', type: FieldType.time }].concat(
-      curves.map((x: any) => ({ name: x.title, type: FieldType.number }))
+      curves.map((x: any) => ({ name: get(query, "context.host.host") + "," + x.title, type: FieldType.number }))
     ),
   });
   zip(...curves.map((x: any) => x.rrddata)).forEach((d: any, i: number) =>

However, this most definitely isn't a proper solution, because it will probably break Enterprise Editions.

there was some refactoring regarding the auto completion: Checkmk/checkmk@684d04f
we probably have to adapt to these changes...

• raw edition: request={"ident":"available_graphs","params":{"strict":"withSource","context":{"siteopt":{"site":"cmk210d"},"host":{"host":"internal"}}},"value":""} -> withSource needs to be replaced

In addition to graphs and single metrics, it would be good if this datasource also offers the possibility to retrieve views and display them in a table.

Example: To show services with issues on a dashboard, I would like to create specific views with filters in Check_MK and present them in Grafana via the table visualization panel. We are currently implementing this using iFrames, which are unfortunately very inflexible.

Hello,

Can you please add a feature to enable alerting with this datasource

Error message includes a wrong version number:

API request was cancelled. This has either happened because no 'Access-Control-Allow-Origin' header is present, or because of a ssl protocol error. Make sure you are running at least Check_MK version 15.0p16.

This should be "1.5.0p16".

Hi,

I don't know how to setup check_mk URL running in :8080 port. Grafana gives error testing and saving.

Testing check_mk Check_MK 1.6.0-2019.07.15 Enterprise. Your latest grafana-checkmk-datasource (16July2019). Grafana 6.2.5.
In the Query menu, most fields operate OK including Mode,Site,Host. But "Service" field is inaccessible.

As user of the checkMK Grafana datasource I want to create graphs that select the available metrics dynamically.

Acceptance:

• We have a concept for graphs with a dynamic number of metrics
• This concept allows use cases like this:
  • Show a summarized metric of the CPU load of all hosts with the label os:linux
  • Show all Disk IO read / write metrics of all hosts matching the regex ".*prod$" as lines

Hi

I am evaluating for a monitoring tool and the check_mk in combination with Grafana (check_mk plugin for Grafana) looks very good, but I have a problem.
I have add the plugging to Grafana but it cannot display anything, it is going till mode, I do not have any metric to select.
I am doing something wrong, can you help me on this?

Hi everybody,
i have the trouble that i try to use the check_mk plugin for my check_mk core.
i have version 2.0.9.
the url is the right one i try to download the api .py via wget and that worked.
but if i setup via grafana check_mk plugin i get the following error after safe and test:
"Could not read API response, make sure the URL you provided is correct."
And its not usable.
can someone help me out?
thanks and kind regards

Hello,

I would like to use the name of a service or the host name as panel title.
Is this possible in any way?

Please update The Grafana PR (grafana/grafana-plugin-repository#421) to version 1.0.1 (33e5c04).

Hi,

today I checked out this plugin (e59e5b0). I integrated it into an existing Grafana (8.4.4) which is running as a Docker container.

I try to connect it to a Checkmk RAW test instance running also within Docker (Checkmk Raw Edition 2.1.0-2022.03.31) and this is what I get:

Checkmk exception: Currently not supported with this Checkmk Edition
Traceback (most recent call last): File "/omd/sites/cmk/lib/python3/cmk/gui/plugins/webapi/grafana.py",

Currently not supported with this Checkmk Edition

According to the docs: „Beginning with version 2.0.0, it is possible in all Checkmk editions to directly address Checkmk as a data source in Grafana“ which in my understanding includes RAW – at least it wouldn't make sense to offer a dropdown containing „RAW“ and „Enterprise“ when RAW won't work.

So please help me: what am I missing?

Regards,
Marianne

Abstract

Zero values (0) will not result in a data point in grafana. The graph will falsely display the last received value greater than zero.

In CheckMK the graph displays the 0 value correctly.

Steps to reproduce

• Add CheckMK Check which will could have 0 values (e.g. using fileinfo.groups to count files in a directory, it could be a valid case that the directory is empty)
• Add grafana table panel and use this newly created checkmk service check as datasource
• Grafana only displays rows having value greater than 0

Versions

• Grafana 6.5.2
  -- CheckMK Plugin 1.1.0
• CheckMK 1.6.0p7 Enterprise

hello,

"Connect null values" option in Grafana panel settings, won't work if there is no data pulled from the check_mk source. At the end, all points are connected.
like on this graf. Query interval is on 60s like in check_mk (enterprice version).

Tested also the Connect null values/Threshold with <2m settings and nothing has changed

the goal is to have such graf

Is it possible to go around with such a problem?
Maybe I missed some settings?

Grafana v8.0.4 (81fef5b4b4)
Checkmk enterprice 1.6.0p19

Marcin

I think this needs the CMC for being able to run? Thus it will not work with the checkmk Raw Edition.
-->

Requirements
Minimal Check_MK Version is Check_MK Enterprise Edition (CEE) 1.5.0p16.

When having selected one "predefined graph" in a query and then changing to "single metric" the previous graph rendering should vanish immediately. At the moment the "predefined graph" metrics are removed once a metric is selected.

The logo is displayed as square. Use the attached one.

As user of checkMK+Grafana I want to be able to make events from the monitoring history available to the viewer of graphs.

Acceptance:

Background:

The monitoring history of checkMK contains state changes, acknowledgements, downtime information and information about notifications. Using the raw history information would be too verbose for Grafana, but based on these information checkMK calculates availability analysis for hosts and services. It could be very useful to make this kind of information available in grafana.

Details about the availability feature can be found here: https://mathias-kettner.com/cms_availability.html

I tried to use the docker image for 1.6.0p2 as CEE and CRE.
Both images don't work properly. I get the following error with

docker run -d -p 8080:50000 checkmk/check-mk-enterprise:1.6.0p2
docker: Error response from daemon: No command specified.
See 'docker run --help'.

Hi there:
I'm testing the last CheckMK version (1.6.0p10) and 7.2.0 Grafana version. I installed within grafana the plugin and the connection was correct, so, adding a new dashboard, new panel, into the query, I can add everything that I need but Metric, under Service.
Clicking in this field doesn't appear the Metric, and if I config it manually, it doesn't work too. I can't take any value of the hosts.

What can be the mistake?
Thanks in advance! :)

Sorry, I sent you the wrong logo. Please update to the attached logo.

Good evening,

I have noticed that the plugin does not work with Grafana v8.3.0. When is an update planned here?

It would be nice if you can use variables in the provided fields eg. host. So it is possible to create dynamic dashboards with rows.

I have set up graphs comparing the Check_MK datasource and the Check_MK via InfluxDB.
Unfortunately they give different results and I believe InfluxDB is correct.
Specifically, you can see this on the Grafana GUI by going Visualisation-> Value->Stat=Current.

But I am sure it is showing Average and not Current at all.
Using software versions;

• Grafana6.1.6
• Check_MK Enterprise 1.5.0p16
• Your Grafana-Datasource 1.01

Problem appears to show it self very easily with CPU utilisation.. for example

As user of the Grafana checkMK datasource I want to be able to add the predefined graphs to my Grafana dashboard.

Acceptance:

• We have a rough concept how the graph definitions (units, scaling) from checkMK can be transported to Grafana
• The transported information is not persited within Grafana. Changes between checkMK updates are applied to Grafana.

Some background information about the checkMK graphing logic:

Each service that has metrics may have a dynamic number of graphs in the checkMK graphing system. The graphs are created based on the the collection of metrics and defined graphs in Check_MK. Most standard graphs are defined in https://github.com/tribe29/checkMK/blob/master/cmk/gui/plugins/metrics/check_mk.py.

When the graphs of a service are requested by a user the check_mk graphing system takes the metrics of the service as input and searches all entries in "graph_info". Each graph_info entry that can be fully populated with the available metrics is rendered for this service.

Example: A service has a metric fan_speed=3200. The graph_info["fan_speed"] entry only requires the "fan_speed" metric to be available. This graph can then be rendered. The metrics list also tells the graph how to draw the different metrics (e.g. as lines or stacked)

Another important structure is the metric_info. It holds entries for each metrics to tell the graphing system which units or colors to use for the single metrics.

The precomputed information can be fetched from the checkMK metric system using the available API calls.

Please Support annotations with various checkmk datasources: For example: comments, Status Changes, acknowledgements, downtimes.

https://grafana.com/docs/grafana/latest/reference/annotations/

There is no way to select the aggregation for the TCP Connections service. It only seems to show average. We need it to show max and min

Hello,
i'm using grafana 8.5.2 (docker) and i followed the check_mk documentation with the git clone method but the data source does not appear in grafana :(
https://docs.checkmk.com/latest/en/grafana.html
what could i have forgotten ?

thank you for your help :)

Actually Grafana set the "Step" Value depends on the timerange, for example a timerange from 405minutes gives a step = 60 back.
A range from 406 minutes gives a step = 120 back.

The Bad effect is: The graph is less detailed over a bigger timerange and for some cases it's necessary to see the little "peaks" for example in 24 hours.

The Query Inspector give me this as result:

405 min relative time:

response:Object
result:Object
step:60
start_time:1574320140
end_time:1574344440
curves:Array[3]

407min relative time:

response:Object
result:Object
step:120
start_time:1574320080
end_time:1574344560
curves:Array[2]

What i Expected:

Check_MK RRD is saving 1 min steps for 2880 points. (default)

So it should possible to used this points in Grafana.

It's not possible to rename a series, so for instance, adding CPU Utilization from multiple servers or hosts lists each series as "CPU Utilization" with no way to differentiate between them.

Possible contents:

1. Download & setup check_mk container like this: TODO
2. Open Check_MK GUI
3. Add a single host to Check_MK and discover the services
4. Get automation user credentials: WATO > Users > automation
5. Checkout grafana-checkmk-datasource to e.g. /home/lm/git/grafana-checkmk-datasource
6. Start grafana like this: docker run -d -p 3000:3000 -v /home/lm/git/grafana-checkmk-datasource/dist:/var/lib/grafana/plugins/checkmk-datasource grafana/grafana
7. Login to Grafana with admin:admin: http://localhost:3000/
8. Configure Check_MK data source (Insert URL and credentials)
9. Configure first graph

We need to be able to count / graph devices in CRIT state against a total count of devices. There is no way to display/represent the status of a device, only to graph metrics.

A bit more overview informations would be awesome.

like 10/440 Hosts in critical state
array of critical hosts
array of warning hosts
anmount of hosts
anmount of services
how much warning state
which warning states and so on

Hi,

I have been using CheckMK and the corresponding CheckMK-Grafana Plugin for visualizing a sort of Network/Host Monitoring. And now i ran into a problem.

I’ve added the checks for some processes on our Windows Server 2019 machines. While the processes are running everything works as expected and i can visualize the Check in Grafana. (Green for process is running). Once the process is not running, i would assume that the check would go red, since there is no process running but grafana throws an exception that it “cannot read property “meta” of undefined”.

i tried the enforced service and it is working more consistently, but there is still 1 problem.

If the process is running and you select the metric within Grafana, the number of processes is at position 5 or so within the possible metrics. If the process is not running there is only 1 metric left and so Grafana can not find the 5th metric within the service and and therefore throws another exception. “e is undefined”.

We’re running on CheckMK-Raw-2.0.0p7.

Kind Regards
Kai Jakobsen

Using a regex in Host filter seems to be not optional and not working at all.
Steps to reproduce:

• Add a Panel and select combined graphs
• Activate regex for Host filter and add the beginning of a host name that matches to at least two hosts (e.g. myHost for 'myHost1' and 'myHost2')
• configure the rest of the stuff and save the Panel - it should work as expected
• Go back to the panel, deactivate regex and select the host directly
• The Panel still shows the metrics for the regular expression.

If you reproduce the steps by not adding a regular expression first, you will not be able to select any graph to show. -> The selection is simply not used.

Hi,

after copieing the Datasource to the plugin-folder and clicking on the new datasource check_mk (without logo by the way) the following Error appears:

Error: Unexpected token '<' Evaluating http://x.x.x.x:3000/public/app/plugins/datasource/checkmk-datasource/module Loading app/plugins/datasource/checkmk-datasource/module
Data Source Error

Grafana: v6.6.0 (5c11bbdfb4)
Check_MK: Enterprise 1.6.0p7

Anything to do for me?

Hello,

After integrating the plugin, I get the following error message on Grafana:

"Fetch error: 404 Not Found Instantiating http://localhost:3000/public/app/plugins/datasource/dist/module Loading app/plugins/datasource/dist/module"

Have tried every version of Grafana and the plugins but always the same. Does anyone happen to know what could be causing this?

Hi,

we're using Grafana Cloud as service and want to configure our check_mk as data source.

Grafana Cloud installs plugins through the public catalog rather than installing from a .zip or GitHub clone, so I currently do not see any way to have them work together.

Would it be possible for you to make the plugin available in the Grafana catalog? According to them, everyone in the community can offer their plugin through https://github.com/grafana/grafana-plugin-repository.

Thanks!

Our installation:

• CheckMK Enterprise in Version 1.6.0p11
• Grafana v7.3.1
• CheckMK Plugin v1.1.0

Grafana is running via docker:

docker run \
 -d \
 -p 8443:3000 \
 --name grafana \
 --restart always \
 --env "GF_AUTH_ANONYMOUS_ENABLED=true" \
 --env "GF_INSTALL_PLUGINS=https://github.com/tribe29/grafana-checkmk-datasource/archive/1.1.0.zip;checkmk-datasource" \
 --env "GF_PLUGINS_ALLOW_LOADING_UNSIGNED_PLUGINS=checkmk-datasource" \
 -v /opt/grafana_data:/var/lib/grafana \
 grafana/grafana

When configuring the plugin, it is shown with a red "unsigned"-badge. Aside from that it accepts my credentials for CheckMK and shows Datasource is working when saving.

However, when creating a new panel there are no sites, hosts or services being offered after selecting "CheckMK" as datasource. The CheckMK user for the login had access to around 8-9 machines before switching to an automation password.

Update: This is a permission issue. When using an administrator account, the Hosts become selectable. There is no mention of any required permissions as far as I can see. What permissions are needed?

This release will include the missing API calls.

Hi, I'm using Grafana with CheckMK Raw 2.0.0p6 and I haven't had any luck when it comes to complex graphs, it doesn't seem like I am the only one: https://forum.checkmk.com/t/checkmk-raw-with-grafana-combined-graph-graph-field-not-selectable/25181/14

The graph preview always seems to stay empty even though I have multiple weeks worth of data on my checkmk server, everything else seems to work, including predefined graphs and single metrics.

In case it might be useful, whatever combination of host and service regex I use, the graph field seems to stay empty. Is there something I'm forgetting or does it work for anyone else?

Thank you!
