Server disappeared from AppD Console

[Selvaganesh.Elavarasan]

Hello Team,

We are using AppD SaaS to monitor our servers infra metrics. We noticed one of the windows servers went down on 13th April 2022 but when we checked now (18th April 2022) we are unable to see the entry in console.

Could you please help me whether the entry will be disappeared from console if the server not reported to AppD for any certain period? If yes can you share some details about it?

Thanks,

Selvaganesh E

Hi @Selvaganesh.Elavarasan,

I did some searching and was not able to find anything super specific to your question, but I want to share this link to our AppD Docs page about Server monitoring. 

https://docs.appdynamics.com/21.10/en/infrastructure-visibility/server-visibility/monitor-your-serve...

Let me know if you find anything that helps - please note the side navigation panel on the pages.

Hi @Selvaganesh.Elavarasan ,

Controller regularly purges stale machines.

Please see document below and search for sim.machines.offline.toStaleTimeoutMillis and sim.machines.stale.purgeIntervalMillis.

https://docs.appdynamics.com/22.4/en/infrastructure-visibility/server-visibility/controller-settings... 

To know the values for your SaaS controller, you may need to submit a support ticket, but default values are 2 days for sim.machines.offline.toStaleTimeoutMillis and 6 hours for sim.machines.stale.purgeIntervalMillis.

Best Regards,

Hiroki
