App Agent Status

[Pranjal.Pandey]

Hi,

I am new to AppDynamics. We have ONPREM installation.

I went into one of our applications--> Tiers and Nodes to check the App Agent Status at NODE level

I have seen some values as 99.4% with UP arrow and 11.5% with down arrow. Can someone please explain what it means for availability of the Agents.

Example:

We have one Tier with 20 Nodes. Some nodes show 52.3% UP arrow, 60.02% UP arrow and some are like 11.81% Down  arrow, 0% Down arrow.

Hi @Pranjal.Pandey,

Thank you for posting to the community.
By clicking the arrow on App Agent Status, you can see details and explanations of App Agent Status.
Up or down arrow represents current status. Up arrow indicates the agent is reporting data and down arrow indicates the agent is not reporting data.
Percentage indicates uptime of the agent, which represents how many times the Agent reported data in the time range.

Best Regards,

Hiroki

Hi @Hiroki.Ito,

does this mean that if there was no app load on that node for the last 1h (and we have set the viewing time frame to 1h) - the agent will report 0%?

In other words, if there is no app load during some time period, the agent will not report anything? 

I am asking this because I thought that even without any data, agent is supposed to contact the controller every 60 seconds?

Hi @Bojan.Živančević ,

The data I mentioned in above comment includes metric data, so the App Agent Status should be 100% if the agent is active even without any app load or business transaction, because the agent still reports periodic metrics.

Agent is supposed to contact the controller every 60 seconds even without any app load as written in the document below.
https://docs.appdynamics.com/21.8/en/application-monitoring/install-app-server-agents/agent-to-contr... 

The agent metric channel posts all new periodic metrics, including JMX, Windows performance counters, and business transaction metrics to the Controller every 60 seconds.

Best Regards,
Hiroki
