New Add-on bundle for Prometheus health Metrics

dakipro · November 13, 2018, 3:33pm

Hello, is there potential/initiative to get this as a plugin in (some of) the store?
Would love to get statistics on what is openhab doing inside prometheus

rlkoshak · November 13, 2018, 8:20pm

Since this relies on so many external services I don’t see how this could be made into a binding or add-on. It could probably be added to openHABian though.

Setting this up is still on my todo list but I don’t have a lot of time to work on additions to my system these days. I’m fighting a bit of bit rot at the moment that is taking a lot of my time (RPi that controls my garage has gone wonky, Wunderground is shutting off it’s free API, etc).

Yes, there is an initiative to team up with Deutsche Telekom and get the metrics into Eclipse Smart Home core. But this may take a little while.
Meanwhile, following the instructions above and in the readme over at GitHub, it is already possible to use our bundle. Just drop the .jar files into your addons directory.
The bundle only relies on the prometheus library bundles, which you can download and also just drop into the directory, it is not relying on any external service!

Hello @friesenkiwi - is the working jar still available on your github? the link of your above is deceased - https://github.com/KuguHome/openhab-prometheus-metrics/releases/download/v0.9/com.kuguhome.openhab.prometheusmetrics-2.4.0-SNAPSHOT.1.jar

I would like to test and feeback on your really promising approach.

have a look at https://github.com/KuguHome/openhab-prometheus-metrics/releases/

I finally got it up & running As it was kind of a challenge, I’m posting the complete instruction here:

To get this cool dashboard in Grafana you need to:

Have a working Prometheus setup. (See https://prometheus.io/docs/prometheus/latest/getting_started/).
Have a working Grafana setup. (See InfluxDB+Grafana persistence and graphing).
Download http://central.maven.org/maven2/io/prometheus/simpleclient/0.4.0/simpleclient-0.4.0.jar and place it in the addons directory. Monitor the Openhab log file and wait until the jar has successfully registered in Openhab.

If loading of the bindings went ok, you should be able to open http://openhabserver:8080/rest/metrics/prometheus and you will see a page like https://github.com/KuguHome/openhab-prometheus-metrics/wiki/Example-scrape . If an error occured in the previous steps, you’ll see a 404 error.
Now add a job in Prometheus. I installed it today so I’m by no means an expert. In prometheus.yaml, add the following under scrape_configs:

  - job_name: 'openhab_metrics'
    scrape_interval: 10s
    scheme: http
    metrics_path: /rest/metrics/prometheus
    static_configs:
    - targets:
      - 'openhabserver:8080'

After a Prometheus service restart, you can browse to http://prometheusserver:9090/targets, and the scraper is up:

## [openhab_metrics (1/1 up)](http://prometheusserver:9090/targets#job-openhab_metrics)

|Endpoint|State|Labels|Last Scrape|Scrape Duration|Error
|http://openhabserver:8080/rest/metrics/prometheus|UP|instance="openhabserver:8080" job="openhab_metrics"|8.967s ago|78.19ms|

Now download the Grafana dashboard from https://github.com/KuguHome/openhab-prometheus-metrics/wiki/Grafana-source and replace the data source “kugu-prometheus” to the correct data source. For me, it was just “Prometheus”.
Import the dashboard in Grafana. Grafana shouldn’t complain about missing data sources.

I’m really impressed by the amount of insight you get when using this dashboard. Thanks, @friesenkiwi !

Great instructions.

Is anyone aware of a similar Prometheus exporter to scrape item values. It would be awesome to be able to expose values like power consumption or lumens or or water flow… to Prometheus’ calculation functions. I did see one approach that could work via exporting values first to MQTT.

https://github.com/hikhvar/mqtt2prometheus looks like it comes somewhat close but since Prometheus need to know whether each metric is a gauge or a counter it would require that each metric is individually configured.

ricadelic · December 15, 2018, 8:23am

You should be able to go via InfluxDB → Prometheus (InfluxDB Now Supports Prometheus Remote Read & Write Natively | InfluxData) or indeed the MQTT way.

friesenkiwi · December 15, 2018, 10:30am

Oh, wow I’m very sorry I didn’t reply in time, somehow I didn’t get or notice the forum mail notifications

Thanks @ricadelic for the detailed instructions. Actually it should be no problem to place all the .jar files into the addons folder at the same time or at a random order. @mdnx the link https://github.com/KuguHome/openhab-prometheus-metrics/releases/ as @ricadelic posted it is the right place to look. The bundle is currently running in several field systems for us in beta state, development is somewhat paused but we are very interested in feedback!

@imaginator I am not aware of a similar approach for a direct item Prometheus exporter.From our point of view, the InfluxDB or any other persistence plugin would be the “correct” way to get the item values (going MQTT->Prometheus seems one step too much for me). We instead wanted to get values/metrics, which were (until now) hidden. Also, to our mind, Prometheus is more of a health metrics monitoring tool and less of a general value scraper. But you can certainly use it that way. It also shouldn’t be too much of a problem, to write an “Exposable” along the lines of https://github.com/KuguHome/openhab-prometheus-metrics/blob/master/com.kuguhome.openhab.prometheusmetrics/src/main/java/com/kuguhome/openhab/prometheusmetrics/exposable/OpenHABThingStateMetric.java which queries the item registry instead of the thing registry and outputs their values.
If it would be “switchable” within the bundle, we could include it, if you do a PR on GitHub.

rlkoshak · December 15, 2018, 6:09pm

I haven’t set this this up myself yet, but my understand is that Prometheus users Grafana as the display. So there shouldn’t be anything stopping you from adding graphs of stuff saved to InfluxDB through Persistence to the same Graphana dashboard.

friesenkiwi · December 16, 2018, 12:09am

Grafana can display all kinds of data sources, including MySQL, Prometheus or InfluxDB, you can mix them on the same board or even on the same graph.

imaginator · December 16, 2018, 6:39am

My thinking on Prometheus is less about the graphing and more about the Prometheus query functions. I’d love to be able to detect water leaks by looking for sustained low values. Or predict energy consumption for the rest of the month. Or hook into the Prometheus alert manager … Or…

friesenkiwi · December 17, 2018, 6:35am

That’s actually a nice idea. As I said, it should be pretty easy to implement.

imaginator · December 17, 2018, 9:50am

…next level awesome would be the ability to include PromQL in rules.

If prometheus(sum(count_over_time(basement-humidity[60m])), then...

diyha · December 17, 2018, 3:01pm

Very interesting suggestion

craigh · May 9, 2019, 12:01am

Does anyone having this working with 2.5.0 release?

I get this error message:

@gersilex just mentioned to me that https://github.com/baaym/openhab2-prometheus-exporter now exists. I’ve got it running and it seems to work for exporting openhab item values. One small issue with UNDEFs.

Hello,
because the existing exporter didn’t suit my needs, i’ve written another one.
https://github.com/gfournetfayas/openhab2-exporter.git
Wrotten in Go, it follows the Prometheus standards.
It is based on the REST API of OpenHAB.
I’ll add stuff to the repo soon (service file for systemctl, grafana dashboard example).
All feedbacks are welcome !

Hello,

I’ve recently had a java heap problem on my openhab and I was looking for a way to monitor it. The great @rlkoshak pointed out this project and it looks very great.

Unfortunately, like others have mention, it doesn’t work on my openhab 2.4 (openhabian on raspberryPi 3)

I followed the instruction of @ricadelic but the problem is the installation of the .jar. For the three simpleclient*.jar, i’ve got no log and i didn’t find any trace of them in karaf (in feature or bundle). Then the last jar, for prometheus-metric give me this error:

2019-10-29 20:00:24.597 [WARN ] [org.apache.felix.fileinstall        ] - Error while starting bundle: file:/usr/share/openhab2/addons/com.kuguhome.openhab.prometheusmetrics-2.4.0-SNAPSHOT.jar

	at org.apache.felix.fileinstall.internal.DirectoryWatcher.run(DirectoryWatcher.java:316) [10:org.apache.felix.fileinstall:3.6.4]

And when I try the web page it says:

{"error":{"message":"HTTP 404 Not Found","http-code":404,"exception":{"class":"javax.ws.rs.NotFoundException","message":"HTTP 404 Not Found","localized-message":"HTTP 404 Not Found"}}}

Is there something we can do about that bundle on 2.4?
