This document describes the health model for the F5 Monitoring Pack monitoring service. The health model consists of a set of monitors, alerts, and event log entries which provide detailed information regarding the health of the service. The Operations Manager Health Explorer can be used to view the monitors associated with the service. The Operations Manager Alert View can be used to view the alerts. The Windows Event Log can be used to view event log entries. See BIG-IP Health Model for F5 Monitoring Pack to view the list of objects in the health model.
In Operations Manager 2007, you can use the Health Explorer tool to define and diagnose failures on your network. Health Explorer gives you the ability to view and then take action on alerts, state changes, and other significant issues generated by monitoring objects on your network. You can start Health Explorer from the Actions pane after you select an object, alert, or event in the results pane. Health Explorer organizes health information into the following categories:
All monitors and rules that are defined for a selected object display in the appropriate category. By default, when the Health Explorer windows first opens, all monitors that are in a failed, or red, state appear expanded. If a monitor contains other monitors, as in the case of a roll-up monitor, all monitors are shown in a hierarchical layout so that monitoring data for all dependent services and applications is displayed. If you want to view more detail on any dependent monitor, you can right-click that monitor and then click Monitor Properties to open another Health Explorer window. When the Health Explorer window is open, you can review a history of diagnostic tests that have run automatically and the output from those tasks. You can also run additional diagnostic tasks. Any task that is formatted as a hyperlink can run directly from the Knowledge tab. The Health Explorer window refreshes automatically every 30 seconds. You can press the F5 function key for an immediate refresh.
The following list include monitors available in the F5 Monitoring Pack that target the F5 Monitoring Service. Certain monitors contain child objects or counters, and the top-level monitors present a summary status based on the worst case status of any child object or counter.
You can open the Health Explorer for any managed device from the results pane for any Active Alert, Diagram View, State View, or from an event.
Most top-level health counters reflect a summary health state of related counters and objects. To view details of specific counters, you can expand the view of summary counters.
In addition to the monitors available in the Health Explorer, there are many conditions whereby event log entries will be created in the F5 Monitoring Log. This log can be accessed using the Windows Event Log Viewer.
When these event log entries are created, alerts will be fired in Operations Manager which can be managed using the Active Alerts viewer or Alert View for the Monitoring Pack Sevice.
These are all rules which generate alerts. Alerts do not return to a healthy state; they are simply fired.
