TCP Monitoring

TCP monitoring allows you to test the availability and response time of your TCP server from multiple locations around the world.

Once you add a TCP monitor for your TCP server, Monitis will start trying to connect to your server at your preset regular intervals of time to check if your TCP server is accessible.

In most cases, failure status is returned by your TCP monitor if:

  • No response from the server within the set timeout
  • Network or connection error
  • Permission error (server behind firewall, Monitis IPs not white-listed, etc)
  • DNS resolving error
  • SSL version not supported by user’s server

Adding TCP Monitor

To add a TCP Monitor, go to the Monitors menu and select Uptime Monitors -> TCP.
Add New TCP Uptime Monitor

The Add Uptime Monitor – Step 1 window will open.Add TCP Uptime Monitor – Step 1

Under URL/IP, enter the URL or IP address of your web site.

Set the port number under Port.

Enter the value (seconds) under Timeout (sec). Your server will be considered down if not responded within this amount of time.

To add more uptime monitors of different types to the same URL/IP, click the green “+” button under Add protocols you would like to monitor (see Adding Multiple Uptime Monitors to the Same URL/IP).

Click Next when finished. The Add Uptime Monitor – Step 2 window will open.
Add TCP Uptime Monitor – Step 2

Select monitor group from the Select Monitor Group combo box. You can also create a new monitor group by clicking on the “+” icon next to Add Group.

Enter a name for your monitor under Enter Monitor Name.

Set the monitoring frequency for your website. By default, the check interval is set 1 min. Move the stepped slider under Check Interval (min) to increase the check interval.

Select the locations you want your website to be monitored from by checking the boxes next to the location names under Monitoring Locations.

Note:  It is strongly recommended to alert only after a monitor has failed from at least two locations for all monitors using multiple locations.  This will reduce network noise.

Click Add when finished.

The Alert Configuration window will appear.
Alert Configuration

–          Click Send to All Contacts if you want to send alerts for this monitor to all contacts.

–          Click Custom Configuration (Advanced) to configure sending alerts for this monitor only to selected contacts. The Add notification rules window will open. Click on the Add Alert Rule button to configure alert rule(s) for your monitor (see Adding Alerts and Managing Alert Rules).

–          Click Don’t Send Alerts if you don’t want any alerts for this monitor to be sent.

Your newly created TCP monitor will appear in your Monitis Dashboard. Wait until it will load the first results.

To manage your monitor, click on the icon in the top right corner of the monitor to open the context menu.

See Managing Uptime Monitors for detailed instructions on how to manage your uptime monitors.
