Measures reported by CyberFwStateTest

Cyberoam uses clustering technology to ensure high availability. In a cluster, two Cyberoam firewall appliances are grouped together and instructed to work as a single entity. In the cluster setup, one of the firewall appliances acts as primary whereas the other one acts as secondary. The high availability configuration always ensures that one of the two firewall appliances is available for maintaining the network traffic so that the downtime of the network is reduced considerably. The firewall appliances can be configured in Active/Passive or Active/Active mode.

If the high availability of the firewall is challenged, the environment may become vulnerable to unknown virus attacks and unauthorized access, both of which can put the environment's security at risk. Hence, to make sure that the environment stays protected around the year from network threats, it is necessary to monitor the high availability status of the Cyberoam firewall. This is where the Cyberoam Firewall State test helps administrators!

By continuously monitoring the target firewall, this test reveals whether the firewall is in standalone configuration or high availability configuration. In addition, this test also reports the number of VPN users who are currently accessing the firewall. Analyzing these metrics, administrators can figure out the mode in which the firewall is currently operating and the workload.

Outputs of the test : One set of results for the Cyberoam Firewall being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
HA_mode Indicates whether the firewall is configured in standalone mode or high-availability mode, and the mode on which the firewall is configured for high availability.   The values that this measure reports and their corresponding numeric values are listed in the table below:
Measure Value Numeric Value
Standalone 1
Active-passive 2
Active-active 3
Note:By default, this measure reports the Measure Values discussed in the table above. However, in the graph of this measure, the high availability status of the firewall is indicated using the numeric equivalents only.
Live_users Indicates the number of users who are currently connected to the firewall. Number This measure is a good indicator of the current workload on the firewall.
