Health check plugin to fix querying getMetricNames in kairosdb 1.1.3. It may work with older versions but I have not tried it.
This plugin will query the metric that is specified in kairos-healthcheck.properties in order to do a backend check.
1 Build the plugin with >mvn package
2 copy the jar file into /opt/kairosdb/lib
3 copy kairos-healthcheck.properties into /opt/kairosdb/conf
4 restart kairosdb
