The Monitoring section of Kemp 360 Central displays the overall health of your HA pairs, Virtual Services, Real Servers, SubVSs, and WAF Statistics (if configured). All statistics update every minute.

Note: In a LoadMaster HA pair configuration, only the shared IP node has a Monitoring section. HA1 and HA2 units do not have a Monitoring section.

System Statistics are updated every minute. In the list view, as the percentage used increases - the bar changes from empty (at 0%) to green (1%) through white (50%) to dark red (99%).

To display the gauges as shown in the figure above, users should click the button with the gauge icon.

The System Statistics section enables users to monitor the following:

  • The percentage of the CPU spent processing in user mode
  • The percentage of the CPU spent processing in system mode
  • The amount of memory in use and the amount of memory free
  • The list view shows the percentage traffic that passes through each eth interface
  • Using the System Statistics section gives users the ability to monitor the statistics for an individual device.

There are a number of different LoadMaster HA statuses that could be present depending on whether units are active, in standby, or inactive as shown below. This status is maintained using an automatic ping between the units.

The unit above is online and operational and the HA units are correctly paired. The A in the middle of the square indicates that this is the master (active) unit. The absence of an ‘A’ in the middle of the square indicates that this is not the master unit (standby).

The master unit above is online and operational but the slave may be offline or misconfigured.

Both the master and slave units above are offline or misconfigured.

The master unit above is offline or misconfigured but the slave is in standby and operational.

The master unit above is online but the HA status is unknown because the last connection to the device failed. Check the credentials of the device and log (both on the device and on Kemp 360 Central).

The slave unit above is online but the HA status is unknown because the last connection to the device failed. Check the credentials of the device and log (both on the device and on Kemp 360 Central).

Note: If you have WAF services configured, you can view WAF details at the network (includes all sub-networks), sub-network (that sub-network only), and individual device level.
