Adding on to what Wes said, we’re (Regina Public Library) a PowerBI shop and import data from Polaris there for reporting and data visualization. Our consortium (SILS) uses Kibana on Elastic for similar purposes. We both use SSRS to schedule data dumps and other reports - though SILS has higher access to SSRS than we do.
We use PowerBI separately from our consortium because we report on a lot more things than just the ILS (events, computer usage, printing, visitor count, etc.). We’re happy to discuss our use of PowerBI further with anyone who is interested.
I know SILS did an IUG presentation on their use of Kibana. It can be found here: Visualizing Your ILS Data With Kibana.
