The Operating System based metrics that are provided with the APIM EP Agent scripts i.e.gatewayOperatingStatus.pl and gatewayOSResoure.pl, are described here



This does not describe in detail the metrics under the JVM and Database branches of the gateway metric tree



Release : 3.4

Component : Integration with APM


The database metrics are derived directly from the output of mysql -e "SHOW STATUS" command and so the meanings correspond with what that command reports. These are documented here for version Mysql 5.7 - check the doc for which ever mysql release in use Below is the link for version 5.7 which is what is shipped with the standard Gateway Appliance 


The JVM metrics are produced by the APIM policy apmJvmMetrics and the metrics produced are based the JVM Metrics Assertion as described in the attached pdf
