But sometimes it drops its connection as you can see in the screenshot at 04:00 till 06:00:</P> <P><IMG src="https://community.dynatrace.com/legacyfs/online/20771-2019-06-06-10-44-50-host-holland-casino-holland-ca.png" border="0" /></P> <P>The stunnel proces does not stop working, it just goes dormant for no apparent reason. There is a log file created by this process but it just stops logging whenever the network drops. Location B is not monitored.</P> <P>This is what I came up with to get a notification but does not work:</P> <UL> <LI>Logfile monitoring does not work because whenever the network drops, it stops logging to the file.</LI> <LI>Create a custom service does not work with type Other.</LI> <LI>The 3 default choices at availability monitoring "if service requests are impacted" (there are no service requests monitored), "if any process becomes unavailable (stunnel keeps running dormant) " and "if minimum threshold is not met (only shown number of instances)" are not working.</LI> </UL> <P>I am trying to figure out how to get a notification whenever the network traffic for this process drops like 80% or more. I cannot figure it out, please help me.</P> <P>&nbsp;</P> Wed, 19 May 2021 08:03:08 GMT https://community.dynatrace.com/t5/Alerting/How-to-set-alerts-for-quot-stunnel-quot-process-of-type-other/m-p/119277#M1502 b_wijfjes 2021-05-19T08:03:08Z https://community.dynatrace.com/t5/Alerting/How-to-set-alerts-for-quot-stunnel-quot-process-of-type-other/m-p/119278#M1503 <P>Try creating Custom Alerts for this process (all instances, not process group):</P><P><IMG src="https://community.dynatrace.com/legacyfs/online/20777-zrzut-ekranu-2019-06-6-o-113043.png" /></P><P>Use measure Bytes received per second and Bytes send per second.
