Monitoring load balancing

From the GUI you can go to Monitor > Load Balance Monitor to monitor the status of configured virtual servers and real servers and start or stop the real servers. You can also use the get test ipldb command from the CLI to display similar information.

For each real server, the monitor displays status (up or down), mode (active, standby, or disable), events, active sessions, round trip time (RTT), and the amount of bytes of data processed. From the monitor page you can also stop sending new sessions to any real server by right clicking and setting the mode to standby or disable. When you select to stop sending sessions, the FortiGate continues to send data for sessions that were established or persistent before you selected standby or disable. However, no new sessions are started.

Real Server

The IP addresses of the existing real servers.

Status

Displays the health status according to the health check results for each real server. A green arrow means the server is up. A red arrow means the server is down.

Mode

The mode of the real server. Can be set to active, standby, or disabled. When set to standby or disabled the FortiGate stops sending new sessions to the server.

Monitor Events

Display each real server’s up and down times.

Active Sessions

Display each real server’s active sessions.

RTT (ms)

Displays the Round Trip Time (RTT) of each real server. By default, the RTT is “<1”. This value will change only when ping monitoring is enabled on a real server.

Bytes Processed

Displays the traffic processed by each real server.
