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.
