Recommended RIS API Data Collector Interval
-------------------------------------------

.. _19.1.1|VOSS-489:
.. _19.1.1|VOSS-349:


As a guideline to determine the interval that the (RIS) data collector service
should poll the Unified CM, consider that:

* it takes about 14 minutes to collect information for around 200K phones on a cluster

The default value of the **RIS API data collector interval**:
``43200`` seconds (12 hours) can be adjusted accordingly. 


.. note::

   Collection processes run in parallel for each Unified CM on VOSS-4-UC.

To adjust the value, refer to the System Monitoring Configuration section
in the Advanced Configuration Guide.
