Description

  • This article is intended to be used only if Perfstat8 is failing to collect performance data or for urgent data gathering situations
    • Note:
      • Performance archives are the primary collection method of performance data on ONTAP 9
      • Perfstat8 should only be collected on Data ONTAP 8.2 or if directed by Support, and perfstat7 for Data ONTAP 8 7-mode.
      • See the perfstat omnibus for download links and directions for your operating system.
  • Perfstat8 can have issues collecting against a cluster with one or more nodes under CPU pressure or due to network issues.
    • This can result in failed Perfstats or Perfstats with partial data, primarily missing the stats * outputs.
    • Errors may be seen similar to below:
