Partition set, shard, and details page

The Partition Set, Shard, and Details pages show varying levels of information regarding groups of partitions or a single partition. These pages are nearly identical in their layout and functionality.

From the Dashboard page, you can view a partition set. From a partition set, you can navigate to shards. From a shard, you can select to view individual partitions. Links at the top of the page provide the ability to navigate backwards up the hierarchy of pages.

Each page provides the following information:

At the partition set or shard levels, the administrator can choose whether to apply the operation to all partitions or a specific grouping of partitions.

The Partition Details page will have the following additional tabs, with the exception of the Refresh Settings tab for primary partitions:

Schedule Settings: The Schedule Settings tab allows the administrator to change the index schedule settings. The fields are initially set from the rollover policy from which the partition was created. If all partitions do not have the same schedule, the Scheduling fields contain dashes to indicate that multiple [schedule] configurations exist. To update all partitions, change the configuration and apply the settings. To change individual partitions, select a partition and change the configuration. Values can not be changed to an unset state. The defaults are: 180-day rollover, primary indexing delay of 12 hours; and indexing runs 24 hours per day.
Backup Settings: The Backup Settings tab allows the administrator to change the index backup settings. The fields are initially set from the rollover policy from which the partition was created. If all partitions do not have the same schedule, the Backup Settings fields contain dashes to indicate that multiple [backup] configurations exist. To update all partitions, change the configuration and apply the settings. To change individual partitions, select a partition and change the configuration. Values can not be changed to an unset state. Backups are disabled by default.
Refresh Settings: The Refresh Settings tab contains the schedule for when the secondary partition will be refreshed from its primary partition. The fields are initially set from the rollover policy from which the partition was created. If all partitions do not have the same schedule, the Refresh fields contain dashes to indicate that multiple [refresh] configurations exist. To update all partitions, change the configuration and apply the settings. To change individual partitions, select a partition and change the configuration. Values can not be changed to an unset state. The default refresh settings if there is a secondary partition are 24 hours per day, every day.

The Partition Operations table

When you click on a partition, a partition set, or a shard in the dashboard a Partition Operations table is displayed.

At the partition level, you can click View Full Log to go to the main Index Operation Log, which provides filtering options.

The table also allows you to click the red X to the right of the action to cancel manual operations. Automatic operations cannot be canceled.
