The TCP connection statistical monitor collects data for active opens, passive opens, attempt fails, connection rests, and current connections. TCP connections statistics are monitored against a threshold value. Alerts are sent when connections surpass threshold values.

Using the TCP connection statistics monitor, various types of TCP connections can be monitored. File check monitors can be added using Setup > Monitoring > Templates > Other Monitors.

After applying the template to a device, the template can be validated if it is assigned to a resource. For more information, see Validate Template.

To create a file check monitor:

  1. Select a client from the All Clients list.
  2. Go to Setup > Monitoring > Templates.
  3. From TEMPLATES, click +Add. The monitor template appears.

      • Standard
  5. After configuring the template, go to Other Monitors and click +Add. The other monitors screen appears.
  6. From the options displayed in Monitor Type drop-down, select TCP connection statistics. The TCP connection statistics screen appears.

The agent sends the following alerts:

  • Warning alert if the TCP connections cross the warning threshold.
  • Critical alert if the TCP connections cross the critical threshold.

After adding a template with a TCP connection, assign the template to a device to start monitoring.

Managing TCP connection statistics

TCP connection statistics details can be viewed and modified when added to a template. Perform the following actions to manage the TCP connection statistics monitor:
