####-##-## 12:26:54.363 ERROR --- [#########-####-######] c.vmware.um.collector.CollectionHelper   : Status (COLLECT_INTERNAL_ERR) for ###-# server 2: Collection error: NullPointerException

Environment

VCF usage meter 9.0
NSX 4.2.1

Cause

This issue occurs because the NSX API is returning a null value for getTargetType() when Usage Meter attempts to collect information related to IDS/IPS configurations.

Resolution

Workaround to fix the issue in the current version:

  • Login to NSX Manager
  • Navigate to Security->IDS/IPS & Malware Prevention
  • Under IDS/IPS Activated Clusters,
  • Disable IDS/IPS on the clusters
  • Enable IDS/IPS on the clusters



    To resolve the issue you can install VCF Usage Meter 9.0.1.0 as an in-place upgrade to resolve the issue. Follow the steps from the document below to upgrade UM.
