Generic (TCP) Service

The Generic (TCP) service monitors the connectivity of a socket on a specified port on a device and, if the port is available, a specific TCP service functioning on the port. 

After the port has successfully passed the test for connectivity, the Generic (TCP) service can continue on to use an appropriate command string to test the TCP service it is monitoring and a validation string against which to check the response it receives. The availability results of the TCP service are then reflected on the status dashboard for the Generic (TCP) service. For example, the command string 201 receiving the appropriate response code 220 indicates that the FTP service is running and available for use. The service also measures the round trip time for the request and the domain name system (DNS) resolution.

You can set a maximum of six instances of the Generic (TCP) service on a device, with each instance monitoring a different port on the device.

The Generic (TCP) service does not use the Warning state.

Service Type

Generic TCP

Instances on a Device

10

Device Class

Server - Generic, Workstation - Generic, Other, Printer, Scanner/Camera, Switch/Router, Laptop - Windows, Server - Windows, and Workstation - Windows

Monitored By

Windows probe, Central Server

Scan Interval

5 minutes

Timeout Value

The time (in seconds) that the MSP N-central server waits before considering the test a failure. The default is 30 seconds.

Port Number

The TCP port number used to monitor the Generic (TCP) service.

Send Command String

A predefined set of characters specific to the TCP service. The string is transmitted upon connection to the host and requests the response about the TCP service.

Validation String

The response you expect to receive from the port that is being queried. If the validation string that you specify is not returned by the port being queried, the service will transition to a Failed state.

Generic (TCP) Status Details

Status Detail

Description

Generic Service Availability

The threshold that determines the availability of the port.

Round Trip Time (ms)

The timefor a request to be sent and received.

DNS Resolution

The threshold that determines whether the device name can be resolved.

If an FQDN has been specified, the service searches for its IP address. If the IP address is found, the state will be Normal. Otherwise, it will be Failed, based on the default settings.

If an IP address has been specified, the service checks only the IP address's format. If the format is correct, the state will be Normal. Otherwise, it will be Failed, based on the default settings.
