InsightIQ can be configured to monitor one or more large OneFS powered clusters. However, the recommendation is not to monitor a single cluster larger than 80 nodes and to monitor no more than 8 clusters or 150 nodes simultaneously with a single InsightIQ instance. As such, this is not an advised solution for extra-large clusters. For monitoring more than eight clusters, the best practice is to deploy an additional instance of InsightIQ.
For more information about configuring and monitoring InsightIQ, see the Administration Guide.
