Hey NetApp Community,   Just sharing this, hopefully it helps other customers if you encounter an issue with AIQUM 9.18 when attempting to add a datasource and receive the following error:   Unable to add cluster datasource. This can occur if the clocks on the systems are not synchronized and the Active IQ Unified Manger HTTPS certificate start date is later than the date on the cluster, or if the cluster has reached the maximum number of EMS notification destinations.   In the "C:\ProgramData\NetApp\OnCommandAppData\ocum\log\ocumserver.log" file you will notice the following error:   2026-06-30 12:14:57,463 ERROR [admin] [default task-15] [c.n.o.r.m.e.GlobalExceptionHandler] Server returned HTTP status 500.HTTP error message :{"timestamp":"2026-06-30T02:14:56.724+00:00","status":500,"error":"Internal Server Error","path":"/acquisition-api/server/datasource"} com.netapp.dfm.collector.OcieException: Server returned HTTP status 500.HTTP error message :{"timestamp":"2026-06-30T02:14:56.724+00:00","status":500,"error":"Internal Server Error","path":"/acquisition-api/server/datasource"}   Which is similar to this KB (but not the actual issue) https://kb.netapp.com/data-mgmt/AIQUM/AIQUM_Kbs/Unable_to_add_cluster_on_AIQUM_RHEL_due_to_missing_acquisition_user    In the "C:\ProgramData\NetApp\OnCommandAppData\ocie\log\server_acq.log" file you will notice the following error: Error Payload from ONTAP: {"error":{"code":"983115","message":"Cannot complete the operation because the filter rules will exceed the maximum rules count (256)."}} Related KB articles:   https://kb.netapp.com/data-mgmt/AIQUM/AIQUM_Kbs/AIQUM_Cluster_Addition_Fails_Due_to_Expired_Certificate_or_Cloud_Agent_Issue  https://kb.netapp.com/data-mgmt/AIQUM/AIQUM_Kbs/AIQUM_fails_to_add_ONTAP_cluster_due_to_a_breach_of_max_number_of_EMS_notification_destinations  In the above KB it states that the "max-filter-rule-count" should be set to 256 but i found with AIQUM 9.18 I needed to increase this to 512. The solution was:   cluster1::> set diag Warning: These diagnostic commands are for use by NetApp personnel only. Do you want to continue? {y|n}: y cluster1::*> event config show -fields max-filter-count, max-filter-rule-count max-filter-count max-filter-rule-count ---------------- --------------------- 50 256 cluster1::*> event config modify -max-filter-rule-count 512   Hope that helps   /Matt ...

Good day, we activated NaBox v4.2.0 email alerts, but we have to fine tune them, i.e. because thresholds differ from the one we defined in AIQUM. What's the suggested way to proceed? import the Data source-managed rules in Grafana-managed rules in order to be able to edit them? P.S.: we also currently find duplicated rules...       ...
