The SystemEDGE agent can run in maintenance mode, where it stops processing all monitor entries and sending traps. Maintenance mode is useful if the agent's system is undergoing a planned outage and you want to avoid receiving false alarm traps.
While in maintenance mode, the agent continues to collect metrics and respond to SNMP requests, but it suspends processing all monitors and history collections. Externally, the agent reports the row status of all monitors as notInService, while it maintains the correct row status internally. The agent saves the current value of all monitors at the beginning of the maintenance window, compares it to the current value at the end of the maintenance window, and sends traps in response to the current value as necessary.
To enable maintenance mode, add the following line to the sysedge.cf file:
sysedge_maintenance
Managing maintenance mode in the configuration file is not as efficient as using the maintenance mode control in the CA Virtual Assurance manager interface. You can toggle maintenance mode from the interface, and the configuration file automatically updates and deploys when the setting changes. The agent performs a warm start when configured through CA Virtual Assurance instead of a full restart. For more information about enabling maintenance mode in CA Virtual Assurance, see the CA Virtual Assurance Administration Guide and Online Help.
