UI overview
The
UI overview
describes various components of DLM app.
Cluster Health panel
You can use the
Cluster Health
panel of the Overview page to view the total number of clusters enabled for Data Lifecycle Manager, the number that are healthy, the number for which a warning is issued, and the number that are unhealthy.
Policies panel
You can use the
Policies panel
of the
Overview
page to view the total number of policies in use and their status.
Jobs panel
You can use the
Jobs
panel of the
Overview
page to view the total number of running and failed jobs and their status.
Recent Issues panel
This panel shows the last four events with severity of warning, critical, or error. For each event, the panel shows the severity, the type, a message that includes the policy name and file icon, and the age of the event.
Clusters map
The
Clusters map
indicates the geolocation of each cluster, using red, orange, and green markers on the map.
Issues & Updates table
The
Issues & Updates table
shows policies that have running jobs but at least one failed out of the most recent 10 jobs. You do not see any policy if its last 10 jobs were all successful.
