- ONTAP 9.4 or older
- Clustered Data ONTAP 8.3
- Data ONTAP 8 7-mode
- This article is intended to be used only if Perfstat8 is failing to collect performance data.
- Performance archives are the primary collection method of performance data on Clustered Data ONTAP 8.3 or higher.
- 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.
