9/26/19 07:59:21 AM CEST [ERROR] [EPAgent.EPAPluginProcessor] Metric name from plugin 'Plugin NETSTAT' is invalid: Metric_Name_Is_Badly_Formed[OSResource-Linux|Network|Network Interface|]

Environment

Release : 10.7.0

Component : APM IA Agents

Cause

Netstat plugin when run from the command line we can see the invalid metrics reported. Reason for this was metric path was badly formed.
We get "Metric_Name_Is_Badly_Formed" exception.

The reason for this was the split function which was used in the plugin was not assigned to any variable to capture the split values. 

Attached the modified netstat plugin (netstat.pl)

Resolution

Provided the fixed version of Netstat plugin (Netstat.pl). Attached netstat.pl

Additional Information

Line 122 was changed from split; to my @spl = split;

And assigned value as @spl instead of $_

Please go through the attached file from Line 122 onwards.
