TCP Port Monitor
The TCP Port Monitor will periodically connect to a port on the defined server and
record how long the connection took. In addition, a text command can be sent, and
a specific text response can be checked for (if no response is specified, the establishment
of a connection is considered successful).
Since connection times are recorded, you can create reports that show connection times
to help you understand when the system is under load.
For example, you could use this monitor to test whether an
HTTP server is accepting connections by specifying the following send text:
GET / HTTP/1.1<enter>
<enter> (blank lines are important for this protocol!)
and then check for response text of '200'. (This is just an example--in this particular case,
it would be easier to just use the Web Page Monitor).
Standard Configuration Options
Like all monitors, this monitor has standard buttons on the right for Adding Actions,
setting Advanced Options and setting the Monitor Schedule.
The TCP Port monitor can create reports based on the port response time from the target server/device. This data can be charted as well as output
in .CSV or HTML tabular form. In addition, you can define what 'up' means and create an uptime report showing a percentage of uptime
over a given time period.
