Limitations on using baseline conditions

A baseline condition is used to specify a multiplier of a baseline value for a metric. Whether it is available when you configure a new metric alert depends on a few other alert detector settings.

For a baseline condition to work, you first need to select a monitored dimension in the alert detector settings. Although this step is not obligatory for other condition types, the baseline condition will not be available for selection if you skip choosing at least one dimension group. Selecting a dimension also means that you choose to receive alert notifications for each representative of the group (for example, every tier or every software service) and not one generic notification for all dimensions.

When configuring an alert using a baseline condition, remember that baseline values used by this condition type may in some situations not be calculated, as is the case during the first 48 hours after you install NAM. To prevent an alert definition from being activated before the baselines are calculated, you need to enable Delayed processing. For more information, see Modifying alert propagation settings.

Another limitation is that a baseline threshold is available only for some dimensions or dimension combinations.

Note

To use an alert based on a baseline condition, you must enable the selected baseline type on the report server. Otherwise, the alert will not be triggered and the notifications will not be sent.

Generic performance alerts

For a generic performance alert, the following dimensions can be used with a baseline condition:

  • Software service

  • Reporting group

  • Application

  • Transaction

  • Tier

  • Site

  • Area

  • Region

  • WAN link name

The important thing to note, however, is that the above dimensions can be used singly or only in one of the following combinations:

  • Software service – server IP address

  • Software service – server IP address – operation

  • Software service – server IP address – task

  • Software service – server IP address – module

  • Software service – server IP address – service

  • Reporting group – software service – server IP address – operation

  • Application – software service – server IP address – operation

  • Transaction – software service – server IP address – operation

  • Tier – software service – server IP address – operation

  • Site – software service

  • Area – software service

  • Region – software service

  • WAN link name – software service

Transaction performance alerts

For a transaction performance alert, the following dimensions can be used with a baseline condition:

  • Application

  • Transaction

  • Region

  • Site

  • Area

The dimensions can be used in the following combinations:

  • Application – transaction

  • Application – region

  • Application – area

  • Application – site

  • Transaction – region

  • Transaction – area

  • Transaction – site

Citrix performance alerts

For a Citrix performance alert, the only dimension that can be used with a baseline condition is a software service. It can only be combined with a server IP address.
