Question How to parse error logs for a specific time period in Plesk?

[Émerson Felinto]

Today at dawn my sites had a brief downtime. But I do not know a reliable way to know if the problem is in Plesk (configuration of apache, nginx and etc) or with the server (problems with the link).
The only information I got was the time the downtime happened. How can I use this to find the CAUSE of the problem?

If you haven't, be sure to whitelist the IPs for the various Uptime Robot servers;

This page is awesome !!! I will integrate all these logs to my papertrail, this way could this problem occur again I can check the logs for a certain period of time =)

Currently my firewall is disabled and I do not see any problem that could indicate blocking the robots uptime servers, considering that the lock should be permanent and not sporadic ...
(OFF-TOPIC) I see here on your profile that you are "Plesk Certified Professional". How can I get a seal like that? ;-)

Thanks for the suggestions but they were very vague and inaccurate! Could you give me more suggestions on how I can find where this problem is specifically?
