On several servers we have a process called "stunnel".
Here are the properties and tags:
This process creates a SSL tunnel from A to B, nothing spectacular. But sometimes it drops its connection as you can see in the screenshot at 04:00 till 06:00:
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.
This is what I came up with to get a notification but does not work:
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.
Solved! Go to Solution.
Try creating Custom Alerts for this process (all instances, not process group):
Use measure Bytes received per second and Bytes send per second. Both should be violating when such situation happens. Check it in network metrics to pick right thresholds.
