I recently noticed a problem with net_connect probe...
I use it mainly to ping servers, and for some reason it stops pinging servers and i cannot understand why.
In the attached screenshot, the two servers that are marked, are not being monitored.
Does anyone has an idea what is causing this ?
Restarting the probe resolves this.. until next time...
Any error message you see in the probe log file ? If nothing try increasing the log level and see if points to any specific error message.
Also check if any of the profiles are not configured correctly in the net_connect probe, even these can cause issues sometimes
After Increasing the log level to 5, it is full with messages like this:
Mar 7 07:18:09:315  nc: req->host->profile soiuimodc current time 1488863889 host run_at 1488752319
for the problematic hosts....
If not already tried, delete the problematic profile and recreate it
See if that helps , in most of the scenarios issues with the net_connect probe would be because of the misconfigured profiles . Also verify the other profiles to see if any one of them is not correctly configured
