Applies to

  • NetApp Data Infrastructure Insights (DII) (formerly Cloud Insights)
  • Brocade Switch Data Collectors (SNMP-based)
  • OnCommand Insight (OCI) 7.3+
  • Fabric Operating System (FOS)
  • All supported Brocade FOS versions (noting FOS 8.2.x is EOL for Brocade support)

Issue

  • Performance data collection fails on Brocade data collectors in DII with SNMP timeout errors, despite SNMPWALK tests from the Acquisition Unit (AU) passing.
    • Example log output:
      • Timed out during sending SNMP request: GETNEXT [contextEngineID=80:00:06:34:b2:10:00:xx:xx:xx:xx:xx:xx, contextName=VF:XXX, requestID=447747206, errorStatus=0, errorIndex=0, VBS[1.3.6.1.3.94.1.10.1.10=Null]]. Current timeout (milliseconds): 5000ms. Retries: 1
    • or
      • No Variable Bindings for table connUnitPortStatTable: -1, Request timed out.
  • DII/OCI Brocade data source fails performance collection with timeout errors.
  • SNMPWALK test from the AU to the Brocade switch is successful.
  • Increasing the timeout from 5000ms to 10,000ms does not resolve the issue.
  • No performance data is collected, or all metrics show zero.
