Manage and monitor snapshot policies
After you create an HDFS, HBase, or Ozone snapshot policy, you can manage the snapshot policies on the “Snapshot Policies” page. You can view more details about the snapshot policy on the "Snapshot History" page.
Snapshot policy details
The following snapshot policy details appear on thepage:
|Policy Name||Shows the snapshot policy you provided during snapshot policy creation.|
|Cluster||Shows the cluster where the snapshots reside.|
|Service||Shows the service as HDFS, HBase, or Ozone for the snapshot policy.|
|Directories/Tables/Objects||Shows the directories, tables, or buckets and volumes you chose for the snapshot policy.|
|Last Run||Shows the timestamp for the last snapshot policy run.|
|Snapshot Schedule||Shows the frequency you chose for the snapshot policy.|
You can use the CLUSTER, SERVICE, and SCHEDULE filters to view the required snapshot policies on the Snapshot Policies page.
- Click for a snapshot policy to view the existing snapshots generated by the snapshot policy.
- Click to modify the schedule of the snapshot policy. You can also modify the tables, directories, or buckets and volumes in the snapshot policy.
- Click to disable the snapshot policy.
- Click to delete the snapshot policy.
Snapshots History details in Replication Manager
You might need to view details about all the snapshot job runs that were run or attempted for a snapshot policy to manage job runs or to perform troubleshooting activities. The "Snapshots History" page in CDP Private Cloud Base Replication Manager provides these details.
You can view the snapshot Policy Name, Type of the snapshot policy, Cluster where the snapshot policy resides, Service, and the automatically assigned Snapshot Prefix for all the snapshot job runs in the snapshot policy.
The Snapshots History page shows a table of snapshot jobs and the following columns for the snapshot jobs:
|Start Time||Time when the snapshot job started.
Click View to open the Managed scheduled snapshots Command page, which displays details and messages about each step in the command run.
|Outcome||Status of snapshot policy as succeeded or failed.|
|Paths | Tables | Buckets Processed||Shows the number of Paths Processed for the HDFS snapshot policy job; the number of Tables Processed for the HBase snapshot policy job; the number of Buckets Processed for the Ozone snapshot policy job.|
|Paths | Tables | Buckets Unprocessed||Shows the number of Paths Unprocessed for the HDFS snapshot policy job; the number of Tables Unprocessed for the HBase snapshot policy job; the number of Buckets Unprocessed for the Ozone snapshot policy job.|
|Snapshots Created||Number of snapshots created.|
|Snapshots Deleted||Number of snapshots deleted.|
|Errors During Creation||Displays a list of errors that occurred when creating the snapshot. Each error shows the related path and the error message.|
