Splunk AppDynamics

Server agent doesn't show hardware metrics on lite version

Hi all,

I'm using AppDynamics SaaS controller lite version. I have deployed a stand-alone machine agent on my localhost for testing purposes.

In the servers tab, I can see the server, but not any of the metrics.

And even in Applications - Tiers & Nodes - Node Details - Server , I cannot see hardware metrics, though it says basic hardware metrics can be monitored without a license.

Why is this ?

Thanks,

Thejan

I figured out the error from debug logs.

I have attached the full machine-agent debug log.

I'm getting the error "RawCollectorUtil - The error log from the collector script was: awk: line 1: missing ) near end of line".
