Thanks for bringing this up.
There are a few scenarios that would happen in your server environment during a server's shutdown/restart. Site24x7 will cover the following scenarios and help you analyze the situation.
Scenario 1 : Proper Shutdown/Restart of a Server
The Site24x7 Windows agent captures this scenario instantly and notifies the user. Later, when the server is UP again,based on the downtime marked in Site24x7, the agent will query the event logs, attach it to the RCA and send it to the user.
Scenario 2 : Force Shutdown/Restart of a Server
As this is a forced scenario, the Site24x7 Windows agent will not be able to notify on the shutdown/restart. If the downtime of the server goes beyond 2 minutes, then we will mark the server as DOWN and alert the user.
Later when the server is UP, based on the downtime triggered, the agent will collect the RCA report including the event logs and send it to the user.
Scenario 3 : Abruptly Stopped/Crash of a Server
In this scenario, the Site24x7 Windows agent will not be notifying about the shutdown/restart of the server. If the downtime of the server goes beyond 2 minutes, then we will mark the server as DOWN and alert the user.
Later, when the server is UP, based on the downtime triggered in Site24x7, the agent will collect the RCA report and send it to the user.
Sample RCA Report - Please read our help documentation on this
50 secs timeout set for Event log query -
After the server is UP, based on the Site24x7 Downtime of that server, the Windows agent will query the event logs and check the events 6008,1076,41,1074. Currently, we have set 50 secs as the default timeout for Event Log Query. In cases where the server is taking a longer time to execute the event log query, it might be timed out and the actual RCA report would not be generated.
So, please have a look at the above cases and analyze the issue further. Request you to share the logs or contact email@example.com to resolve the issue.
