On several servers we have a process called "stunnel".
Here are the properties and tags:
- Type: Other
- Bitness: 32-bit
- EXE name: STunnel.exe
- EXE path: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX\STUNNEL.EXE
- Ports: 8586
- Process group: stunnel - multiplatform SSL tunneling proxy
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:
- Logfile monitoring does not work because whenever the network drops, it stops logging to the file.
- Create a custom service does not work with type Other.
- 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.
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.
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.
