SCOM 2019 UR3 - Dashboards views not refreshing or just timing out
Morning, I made a series of dashboards, each in different folders for customers, along with different views. The views work consistently. The dashboards either do not refresh when selected or just sit there with the little circle spinning forever then just time out. I used the SQL Server Dashboards Template/Data Center Dashboard which is really good, as I can add groups and customize things. I have been using this for quite a while with no issues. Then one morning things just seem to not work. I have not made any updates or changes in some time.
Would appreciate some pointers, advise, tips to fix this.
Thank you,
Tony
