System monitoring model counts
------------------------------

.. _19.1.1|VOSS-349:


The ``sysadmin`` user defines a list of **Models to Aggregate** on
the **Metric Collection** tab of the **Configuration** menu 
(menu model: ``data/SystemMonitoringConfig``). By default,
the following models are included in the list:

::

    device/cucm/CallPickupGroup
    device/uccx/Agent
    device/uccx/Team
    device/uccx/ContactServiceQueue
    device/uccx/ResourceGroup
    data/BaseSiteDAT
    device/cucm/User
    device/cucm/Phone
    device/cucm/HuntPilot
    data/InternalNumberInventory
    data/HcsDpE164InventoryDAT
    device/cucm/Line
    device/cucm/User
    device/cucm/DeviceProfile
    device/cuc/User
    device/spark/User

For these models, counts are collected daily. Daily, weekly and monthly aggregates
*at a particular hierarchy: Provider, Customer or Site* are then stored as a **Grouping**.
In other words, the counts include all hierarchy nodes below the particular hierarchy.

In the instance details, the **Group Number** is then the nth day, week or month of the year.

.. note::

   For daily aggregates, only the most recent daily aggregate of the week is stored.
   Previous daily aggregates are aggregated into this daily aggregate and are then deleted.


A particular daily or weekly Model Counts instance will then 
show the **Average Count** of instances as specified in the **Models to Aggregate**
list.


The data is also displayed as usage charts on the Admin Portal.
