View Refresh Rate

Configuration Manager can manage up to 1200 views at the same time, and manage a maximum of 100 views that are frequently updated, according to the offline analysis repeat interval.

The view refresh rate is important when you manage many views. Since the offline analysis process takes some time to run, and therefore can put a burden on the Configuration Manager and UCMDB systems, you can tune the refresh rate and balance the load on the systems. The following table provides information about each of the options:

Once per day
  • Notifications are not received from UCMDB regarding changes in the results of the TQL query for the managed view.
  • The offline analysis process runs whether or not there were changes in the view.
  • The calculation for a specific view may be delayed if there are multiple managed views that are updated once per day, since the calculations for multiple views are performed sequentially.

  • Exceptions to updating a view only once per day occur when you:

    • first manage the view (affecting view comparison, statistics, and snapshots).
    • initiate policy calculation, and the selected view is in the scope of the policy.
    • authorize a CI in a different view, and that CI is also managed in the selected view (affecting view comparison, statistics, and snapshots).
When view is updated

  • The analysis is run according to the Offline Analysis repeat interval.

  • The view uses an active TQL query in UCMDB.
  • You receive notifications of changes from UCMDB regarding the change in TQL results from the view.
  • The offline analysis process only runs if there were changes in the view.

You may want to take the following issues into account when deciding on the view refresh rate:

What is the priority of the TQL query in UCMDB? If it is low, then there may be no need to update the view in Configuration Manager more than once per day.

How often does the discovery run in UCMDB?

 If the discovery process runs less often than once per day, then there is no benefit to updating the view more than once per day.
What often do you expect the view to change? If not very often, then there is no reason to request frequent updates..
How important is it for you to get updated information? If it is very important, then update the view more frequently than once per day.

How large is the view?

 Updating large views that change frequently can put a load on Configuration Manager and UCMDB. Consider updating Configuration Manager only once per day, unless it is important to get more frequent updates for this view.
