Introduction

  • There are several methods you can use to monitor the performance of a PowerScale cluster.

    The primary method is through a tool called InsightIQ (IIQ). You can deploy this tool as a VMware .ova file virtual machine. Alternately, you can install the tool on a bare-metal Linux server. We recommend using InsightIQ because it retains a history of the cluster performance that you can use to review performance trends, identify behavioral patterns, and perform basic file analytics.

    The second method is through the OneFS CLI. This method can be useful to look at near real-time performance metrics. Also, there are some metrics that can only be accessed using the CLI. The use of the CLI is out of scope for this document.

    The third method is to use the OneFS Platform API (PAPI). This method provides access for third-party tools or in-house scripts to directly query the cluster. The capability is limited only by the third-party tool or scripts. Access to statistics using PAPI is also out of scope for this document.
