This component monitor tests the ability of a TCP/IP-based service to accept incoming sessions. The Monitor tries to establish a socket connection using the Connect method of System.Net.Sockets. TcpClient class in the .NET framework. The elapsed time for a connection is saved as Response Time in the result.

For an overview about component monitors, see Work with component monitors.


This component monitor does not compute a statistic.

Prerequisites for Orion agent for Linux

If using Orion agent for Linux for monitoring, you only need to supply the port. No additional requirements are needed.

Field Descriptions


This field provides A default description of the monitor. You can override the default description by adding to or replacing the text, which is automatically saved. The variable to access this field is ${UserDescription}.

Port Number

This field is the TCP protocol connection port. The default value is 80.

Response Time Threshold

This field allows you to set the warning and critical threshold conditions based on the response time. The response time is the time in milliseconds it takes SolarWinds SAM to determine that a component is not Down and to retrieve any statistical data. See Application Monitor Thresholds.

User Notes

This field allows you to add notes for easy reference. You can access this field by using the variable, ${UserNotes}.
