Process filtering Machine Agent

[Abhi.Bajaj]

AppDynamics Machine Agent by default monitors 20 process classes. These process classes are made up of multiple of the same extension of processes and can change depending on which process is referred to as top during the time frame selected by the machine agent. The ideal way to use process monitoring using a Machine Agent can be achieved by filtering out the processes.

How to filter out the process

• You will need to modify your ServerMonitoring.yaml file present at <MA-Home>/extensions/ServerMonitoring/conf/ServerMonitoring.yaml file
  

  processMonitorConfig:
    maxClassIdLength                 : 50
    processSelectorRegex             : ".*java|.*machineagent.jar|.*amazon.*|.*dockerd.*|.*containerd.*"
    minLiveTimeMillisBeforeMonitoring: 60000
    maxNumberMonitoredClasses        : 20
    processClassSelectorRegexList :
         machineAgentTasks: '.*java.*machineagent.jar'
         containerd: '.*containerd.*'
         amazon:  '.*amazon.*'
         docker: '.*dockerd.*'​

In the above example:
processSelectorRegex is used to select which processes will be monitored by the machine agent and afterward, we are grouping it by using processClassSelectorRegexList. 

A screenshot is attached to give you an idea of how it will look.

Note: Same extension class example: All Java classes will be grouped together. Machine Agent is a Java process, so I grouped them in processClassSelectorRegexList.
