Monitoring specific port from specific server




I have server A and server B. I need to monitor specific port is available on Server B from Server A. What sensor i need to use?

Example: Server A -> Server B:8080

Defaul Port Sensor can only check availability of Server B:8080, but can't do this from another specific server.

Hello Vasily,

this is only possible if you do one of these:

  • install a remote probe on server A
  • write a custom sensor script, logging into server A in order to open a telnet connection onto B on that port
  • scheduling that script on server A and sending the result to an HTTP Push sensor on a PRTG probe
