Disable Custom Program Monitoring

Custom program monitoring is enabled by default. You can disable it if you do not want to monitor programs other than Hadoop tasks, or as recommended by Pepperdata Support for troubleshooting.

Important: A single global control switch enables/disables custom program monitoring and extended JMX metrics collection. To continue collecting JMX metrics, you cannot disable custom program monitoring. Instead, remove all programs from the list of custom-monitored programs by editing your rules file to remove all your custom program matching rules and to override the rules for the programs that Pepperdata is preconfigured to monitor, and skip the steps in this procedure. See Override Preconfigured Program Monitoring.

Procedure

Beginning with any host where Pepperdata is running, add the property that controls custom program monitoring to the Pepperdata site file, pepperdata-site.xml, and set its value to false.

By default, the Pepperdata site file, pepperdata-site.xml, is located in /etc/pepperdata. If you customized the location, the file is specified by the PD_CONF_DIR environment variable. See Change the Location of pepperdata-site.xml for details.
```
<property>
  <name>pepperdata.agent.program.monitor.enabled</name>
  <value>false</value>
</property>
```
Malformed XML files can cause operational errors that can be difficult to debug. To prevent such errors, we recommend that you use a linter, such as xmllint, after you edit any .xml configuration file.
Restart the PepAgent.

You can use either the service (if provided by your OS) or systemctl command:
- sudo service pepagentd restart
- sudo systemctl restart pepagentd
Repeat steps 1 and 2 on every host where Pepperdata is running.
