we have done an upgrade from 10.2 to 10.3 last week. Today I noticed the dashboard tab of all monitored servers takes multiple minutes for loading, stating "connecting".All other tabs respond in a normal way but it seems that tabs with multiple grafics like Ressources need longer loading. Alerting & Reporting works well.
We got a dedicated SQL Server for Diagnostic Manager Database hosting. SQLdmManagementService puts a permanent load of 50-70% on the SQL Server CPU, even if no Console is conencted.
In know issues of 10.3 I see nothing like this, instance and service restart do not change anything. Are there any issues causing diagnostic manager high CPU usage?
Based on the description that you provided, the first thing that I would recommend would be to upgrade to the 10.3.1 release. The description that you provided appears to match some of the fixed issues that are listed for the 10.3.1 release. You can find the release notes at the link below.
If you continue to have issues after the upgrade, it'll be worthwhile to contact IDERA support.
thank you for this hint. Installed 10.3.1, problem solved!!
