F5 health monitors in NPM

To monitor the health of your load balancing environment, NPM polls health monitors on your F5 servers (nodes), and on F5 pool members. Health monitors run periodic tests for network service availability, such as ICMP, HTTP, IMAP, or MSSQL.

To get the health statistics, F5 iControl API must be enabled.

F5 health monitors are not related to hardware health. The status of an element is based on health monitors polled by F5 iControl API.

Go to a pool member or an F5 server details page to review the health monitors widget.

Health monitors require at least one pool member to be up. If no pool members are up, the LTM, the virtual server, and the pool will all be marked as down. Drill down into the pool member to see why it is down.
