This extension requires AppDynamics Java Machine agent.
Process Monitoring Extension gathers process metrics from a Linux/Windows/Solaris/AIX machine and reports to AppDynamics Controller. It utilizes the ps command in Unix like systems and Sigar library in Windows to fetch basic process metrics.
This can also be used as a process checker (identify whether a process is running/not running) by its metric "Running Instances". If the configured process is not running, the "Running Instances" metric value reported is "ZERO".
Apart from the "Running Instances" metric, other process metrics are reported ONLY if the extension detects a single instance of the process running ("Running Instances" metric value is "ONE").
Note: If running on Windows, this extension has Sigar dependencies. Please make sure to copy Windows OS related Sigar files (sigar-*.jar, sigar-amd64-winnt.dll, sigar-x86-winnt.dll) from
Before the extension is installed, the prerequisites mentioned here need to be met. Please do not proceed with the extension installation if the specified prerequisites are not met.
Note: Please make sure to not use tab (\t) while editing yaml files. You may want to validate the yaml file using a yaml validator
Note: Please use workbench mode to verify the metrics while experimenting with various configurations in config.yml to arrive at the desired result.
Edit the config.yml file in
<MACHINE_AGENT_HOME>/monitors/ProcessMonitor/ to update the following.
metricPrefix: The metricPrefix of the extension has to be configured as specified here. Please make sure that the right metricPrefix is chosen based on your machine agent deployment, otherwise this could lead to metrics not being visible in the controller.
instances: process instances that are to be monitored.
displayNamewhich is mandatory is used to render the process name on the metric browser and all the process metrics are reported under this name. The process to be monitored can be configured in three ways:
pidFile. regex is a regular expression used to match the process and is built based on the command line path to the process.
instances: - displayName: "machine agent" regex: ".* machineagent.jar" - displayName: "ssh" pid: "1056" - displayName: "mysql" pidFile: "/opt/mysql/db/mysql.pid"
linux: process: "ps -eo pid,%cpu=CPU%,%mem=Memory%,rsz=RSS,args" solaris: process: "ps -eo pid,pcpu=CPU%, -o pmem=Memory%, -o rss=RSS -o args" aix: process: "ps -eo pid,pcpu=CPU%,pmem=Memory%,rss=RSS,args"
metrics(Optional). Existing metric properties can be modified in this section. If additional metrics are added in the commands, please configure them here with appropriate metric properties for extension to report these metrics. Supported properties are
metrics: - CPU%: multiplier: 1 - Memory%: alias: "Memory%" - RSS: alias: "Resident Set Size" - Running Instances: alias: "Running Instances"
Additional metrics can be configured in unix like systems by adding them to the respective commands in config.yml. For example if Virtual Memory Size of a Linux process is needed, the linux command can be modified to the following
linux: process: "ps -eo pid,%cpu=CPU%,%mem=Memory%,rsz=RSS,vsz=VSZ,args"
and the metric properties to
metrics: - VSZ: alias: "Virtual Memory Size"

Workbench is an inbuilt feature provided with each extension in order to assist you to fine tune the extension setup before you actually deploy it on the controller. Please review the following document on How to use the Extensions WorkBench
command line here is "java -jar machineagent.jar" and regex could be ".*machineagent.jar" Windows
Linux command: ps -eo pid,%cpu=CPU%,%mem=Memory%,rsz=RSS,args | grep "java" Output: 2877 57.3 1.6 264708 java -jar machineagent.jar
command line here is "C:\machineagent-bundle-32bit-windows-220.127.116.11\jre\bin\java.exe -jar machineagent.jar" and regex could be ".*java.exe -jar machineagent.jar"
wmic process get /format:list | findstr java Output: Caption=java.exe CommandLine=jre\bin\java.exe -jar machineagent.jar Description=java.exe ExecutablePath=C:\machineagent-bundle-32bit-windows-18.104.22.168\jre\bin\java.exe
process command line: "/opt/push-jobs-client/bin/ruby /opt/push-jobs-client/bin/pushy-client -c /etc/push-jobs-clientb" regex Matches ".*pushy-client.*" True ".*pushy-client .*" True ".*pushy-client .*" False ".* pushy-client.*" False
Please test your regex using any of the online validators (eg: regextester).
