12 Health monitoring
The following sections describe health monitoring in DPMC.
12.1 Heartbeat status
DPMC constantly monitors Prism Central, Avamar and Data Domain heartbeats; it displays an alert if the
heartbeat is missing for any one of these components.
12.1.1 Avamar heartbeat
DPMC constantly monitors the Avamar Heartbeat. If the heartbeat check fails, DPMC attempts to reconnect
every 5 minutes to ensure the connection can be established. If no connection was established after the initial
5 minutes, DPMC will begin generating alerts. You are notified with a critical alert that the Avamar server
connection is lost. The system also displays the timestamp when the alert was generated.
DPMC attempts to re-establish connectivity every minute. During this time, tasks from the VM or cluster
pages (on-demand backup, manage clusters and others) cannot be initiated.
DPMC turns the health indicator grey on the home dashboard for the following:
• Avamar server
• Backup summary
• Data Domain server
• Avamar utilization
• Data Domain utilization
DPMC displays the Attention icon next to the Cluster Name entry in the cluster table or VM table for every
cluster until the Avamar heartbeat is restored. Hovering over the icon displays the following message: Avamar
server is not reachable.
After 30 minutes, if the heartbeat check has failed for all retries, DPMC sends an additional notification every
30 minutes that the Avamar server is disconnected.
12.1.2 Data domain heartbeat
DPMC constantly monitors the Data Domain connection status through the Avamar server. It utilizes the
information that it gathers from AVE monitoring Data Domain. If the monitoring status shows that Data
Domain is disconnected, DPMC retries before an alert is generated. The severity of the alert is Critical.
DPMC attempts to re-establish connectivity everyminute. It presents the following conditions:
• Keeps all last known Data Domain data for VMs and clusters in the cluster table, VM table and home
dashboard.
• Turns the Data Domain server health indicator grey on the home dashboard.
• Turns the Data Domain utilization indicator grey on the home dashboard.
• Does not allow tasks to be initiated from the VM or cluster pages (on-demand backup, manage
clusters and others).
• Displays the Attention icon next to the Cluster Name entry in the cluster table or VM table for every
cluster or VM until the Data Domain heartbeat is restored. Hovering over the icon displays the
following message: Data Domain server is not reachable.
