sensu-plugin | A framework for writing Sensu plugins & handlers with Ruby | Monitoring library

The problem is, that sensu_gem is not able to install a gem directly from a github repository, so the sensu-plugins-mysql was always installed from rubygem.org. I had to generate my own gem with a different name and publish it to rubygem.org.

Add boundary conditions where needed.

You need to pass the pattern as a string literal, not as a Regexp object.

Thus, you need to remove the regex delimiters and change the modifiers to their inline option variants, that is, prepend the pattern with (?im).

The examples I have seen for Prometheus service checks relied on the blackbox exporter:

The blackbox exporter will try a given URL on the service. If that succeeds, at least one pod is up and running.

See here for an example: https://github.com/prometheus/prometheus/blob/master/documentation/examples/prometheus-kubernetes.yml in job kubernetes-service-endpoints

The URL to probe might be your liveness probe or something else. If your services don't talk HTTP, you can make the blackbox exporter test other protocols as well.

Add the parentheses

You could use Array#forEach to iterate over every output entry and look for warning or critical keywords.

Download the nagios plugins from https://kb.op5.com/display/HOWTOs/Jboss+Monitoring+with+check_jmx

and use with sensu.

Name:- check_jmx

For thread cound command:-

./check_jmx -U service:jmx:rmi:///jndi/rmi://'servername':'port'/jmxrmi -O java.lang:type=Threading -A ThreadCount -K 9200 -w 250 -c 300

For Heap Memory:-

./check_jmx -U service:jmx:rmi:///jndi/rmi://'servername':'port'/jmxrmi -O java.lang:type=Memory -A HeapMemoryUsage -K used -I HeapMemoryUsage -J used -vvvv -w 102400 -c 81290
