How to shutdown a server gracefully?

[kwangxi]

Hi，

Does anyone know the proper way (gracefully) of shutting down a server?

Overview:

• AIX server was shut down for maintenance purposes.
• one agent is not running after restarting the server, later it was due to endpoint corruption which has been claimed was due to the server being shut down ungracefully.

Problems:

• It was likely due to shutting down the server ungracefully. Hence I wanted to ask what's the way of shutting down the server gracefully.
• As per documentation (https://www.dynatrace.com/support/help/platform-modules/infrastructure-monitoring/hosts/monitoring/h...), shutting down properly would return as shutdown (in grey) NOT offline (in red). 
• I have tried a few methods to shut down the server, however, all returned as OFFLINE (in red) which implies an ungracefully shutdown.

Below are the shutdown methods I have tried:

-Shutdown via virtual manager
-Command shutdown
-Command sudo shutdown
-Command poweroff
-Command init0
-Command shutdown -P +1

Conclusion:

1. I wish to understand the proper way of shutting down the server which will return as SHUTDOWN not OFFLINE.
2. And also how Dynatrace classifies graceful and ungrateful shutdowns although we are using the correct shutdown events as per above.

This is really good question. I too want to understand this. Appreciate is someone from Dynatrace product team can pick this up.

Hello @kwangxi,

Can you share details about the endpoints corruption?

We have similar issues since few months after the restart or some servers and the corruption of files like deployment.conf.

Thanks for your help.

Hello,

One thing you'd want to make sure you rule out is the part in the documentation shared about "alerting on graceful shutdown" and making sure that setting is turned off.
