How to disable notifications from Health Monitor for a particular service?
1. Go to Plesk > Server Health and download the configuration file. Configuration file is in a format of XML.
2. Open it with a text editor.
3. To exclude notifications for a particular service, for example nginx, comment out blocks like the following:
CONFIG_TEXT: <!-- <service name="WebProxy" monitor="true">
<alarm level="red" threshold="1" type="percent"/>
<alarm level="yellow" threshold="1" type="percent"/>
Note: along with email notifications Plesk will not show Needs attention/Problem status at Server Health section if the excluded service consumes a lot of resources. However, actual values will be displayed properly.
