5.5. Managing Partition Events
When an agent is assigned to be managed by a server, that is a partition. Partition events are almost like log messages that occur whenever a change in the partition configuration occurs.
5.5.1. Viewing Partition Events
The partition events log is accessed in the high availability configuration.
- Click the Administration tab in the top menu.
- In the menu table on the left, select the item.
- The partition events page lists all of the events that have been recorded. (Table 9, “Partition Events Entries” describes the different fields.) Click the type name of any partition event opens up that record with more information about how the partition assignments were affected.
The partition events log can be filtered to display entries which match the type, status, or details in the event record.
There are basically four categories of partition events that are recorded.
- Affinity group changes
- Agent events
- Server events
- Partition changes
All of the recorded events are listed in Table 8, “Types of Partition Events”.
