OH Metrics core bundle & IO addon

This preview of the openHAB metrics support contains the two new bundles to include them in existing installations:

• the openhab core "Monitor" bundle to replace the existing one
• the new open IO Metrics addon

Installation

Replace the core "Monitor" bundle

• copy over the org.openhab.core.io.monitor-3.1.0-SNAPSHOT.jar to your openhab(ian) machine, e. g. /home/openhabian
• open the Karaf console: sudo openhab-cli console and log in (see documentation for default password)
• Find out the ID of the existing Monitor bundle and stop it:

openhab> bundle:list | grep Monitor
150 │ Active │  80 │ 3.0.0                   │ openHAB Core :: Bundles :: Monitor
openhab> bundle:stop 150

• install the new Monitor bundle:

openhab> bundle:install file:///home/openhabian/org.openhab.core.io.monitor-3.1.0-SNAPSHOT.jar
Bundle ID: 274
openhab> bundle:start 274

Now the new Monitor bundle shoudl be running.

openhab> bundle:status 274                                                                                                                                                                                                                                                                                                                                               
Active

Install the IO Metrics Addon

• copy over the org.openhab.io.metrics-3.1.0-SNAPSHOT.jar to your addons folder, e. g. sudo cp ./org.openhab.io.metrics-3.1.0-SNAPSHOT.jar /usr/share/openhab/addons/ in an OH3 Openhabian installation
• the new addon should be picked up automatically by openHAB:

18:41:44.165 [INFO ] [org.openhab.io.metrics.MetricsService] - Metrics service available under /metrics.

Check

Fire up http://openhab:8080/metrics/prometheus in a browser (replace openhab hostname obviously). You should see a textblock of metric output.

Problems?

• If there errors a la are java.lang.NoClassDefFoundError: org/LatencyUtils/PauseDetector restart the core bundle using the Karafe console:

openhab> bundle:restart 274

• When A newer version of openHAB is required for thread pool metrics to work. is reported, the addon just needs a moment more to realize the core bundle is there...
