We have a dedicated Debian X64 server, running projects and we require availability under any situation. Since last 2 days we have noticed that the server went offline for 10-15 minutes, and then it was back again.
Nothing is more problematic than a server which surprisingly is offline as high availability is one of our requirement.
Is there any way we can be notified if the server is offline. I checked for something similar and found this, but this checks periodically, I would like to know how much time it went offline as soon as the server is up and running again.
Thank you.
