Monitoring of Specific Local Network Port and Distant (reacheable port)

We request a Plugin that would basically  check the status of a specified local port  or a reacheable port from where the agent is residing.

USE CASE #1 ( Local Port )

This would be usefull to validate the status of an application port . Sometimes an application can be up , but its port is not live at all . 

USE CASE #2 ( Reacheable / distant Port from the local host ) 

This is very important when you want to confirm if from a local host the distant port from a server is reacheable  ( FQDN Based and IP Based )

How Instana agent could handle this ? 

I would suggest that a pluggin be created and have a config file that would that this into considration Those elements are also based on the Monitoring File 

• Name : Name of the monitor   - This could have application name or anything usefull and unique and permit multiple probes
• Interval :  Interval variable as descrived in the event_interval Section
• event_interval : Variabled to set different interval when to check for the port availability 
• type :  Internal / External -  Internal for Local Port / External for distant port
• Port : Port number to check the status
• destination : Only in the case we are specifying an External as a type . FQDN or IP 
• Condition : 
• Severity : <Warning or Critical>   This is more as a nice to have as by default a port that is down/unreacheable is not a good behavior

How Instana UI could handle this ? 

I would suggest the same look and feel as Monitoring File
