Avamar: Administrator UI reports an incorrect Data Domain Status due to a busy system

The Avamar monitoring status for Data Domain (DD) changes to yellow or red from green in the Avamar Administrator UI.

• Error: Unable to get SNMP file system status
• Error: Unable to get file system information
• Error: Unable to get disk status
• Error: Unable to retrieve ssh keys

Avamar uses Simple Network Management Protocol (SNMP) queries to Data Domain to retrieve Data Domain stats (such as serial number, disk status and so forth).

Avamar expects the Data Domain to reply with answers for these specific SNMP queries within a specific time limit. 

Various reasons (such as a busy network or high utilization) can cause the Data Domain may take more than the expected time limit set by Avamar. The result is these invalid, false positive, status messages.

1. Log in to the Data Domain in admin mode per Avamar: How To Access a Data Domain System

2. Check the Data Domain activity for the number of connections being handled by the Data Domain:  

ddboost show connections

3. Check the utilization of the Data Domain to verify if Disk or CPU utilization is above average limits. (If yes, Create a Service request with Dell Technologies Data Domain support to find the root cause.)
