C.4.4. General::TCP Check

The General::TCP Check probe tests your TCP server by verifying that it can connect to a system via the specified port number. It collects the following metric:
  • Remote Service Latency — The time it takes in seconds for the TCP server to answer a connection request.
The probe passes the string specified in the Send field upon making a connection. The probe anticipates a response from the system, which should include the substring specified in the Expect field. If the expected string is not found, the probe returns a CRITICAL status.
