Data Infrastructure Insights (DII)FSx data collectors

Issue

After installing the Data Infrastructure Insights (DII) FSx data collector the audit log generates a high volume of entries attributed to the DII collector user account.
 
Symptoms include:
  • Tens of thousands of audit log entries per day (e.g., ~65,000/day) from the DII collector user
  • Audit log entries showing "Insufficient privileges:  user '<username>' does not have write access to this resource" for aggr-check-spare-low ZAPI
  • Audit log entries showing "authentication failed" from "unknown:unknown" for ZAPI calls, even when the DII collector login succeeds (HTTP 200)
  • Data collection in DII completes successfully with no errors reported in the DII console
  • Audit log signal-to-noise ratio is degraded, making it difficult to identify legitimate security events
Example audit log entries:
aggr-check-spare-low :: Error: Insufficient privileges:
user '<username>' does not have write access to this
resource
authentication failed from unknown:unknown
(ONTAPI/ZAPI call)
