FAQ
Is there a way to allow per SVM level user views? I need to offer 1 tenant per SVM. Can I limit visibility to specific SVMs? Is there an SVM dashboard available?
You can do this with Grafana. Harvest can provide the labels for SVMs. The pieces are there but need to be put together.
Grafana templates support the $__user variable to make pre-selections and decisions. You can use that + metadata mapping the user <-> SVM. With both of those you can build SVM specific dashboards.
There is a German service provider who is doing this. They have service managers responsible for a set of customers – and only want to see the data/dashboards of their corresponding customers.
What permissions does Harvest need to talk to ONTAP?
Permissions, authentication, role based security, and creating a Harvest user are covered here.
How do I make Harvest collect additional ONTAP counters?
Instead of modifying the out-of-the-box templates in the conf/ directory, it is better to create your own custom templates following these instructions.
How are capacity and other metrics calculated by Harvest?
Each collector has its own way of collecting and post-processing metrics. Check the documentation of each individual collector (usually under section #Metrics). Capacity and hardware-related metrics are collected by the Zapi collector which emits metrics as they are without any additional calculation. Performance metrics are collected by the ZapiPerf collector and the final values are calculated from the delta of two consequent polls.
