C.4.4. General::TCP Check
The General::TCP Check probe tests your TCP server by verifying 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 will pass the string specified in the Send field upon making a connection. The probe will
anticipate 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.
