Creating/Editing an Anomaly Profile

Anomaly profiles are used to generate anomaly lists starting from job results. Anomaly lists can be created to point out performance problems.
An anomaly profile contains a list of anomaly types. A counter, three thresholds and a criteria (greater than, less than ...) is associated with each anomaly.

To create a new anomalies profile: 

  1. Select the File/New... menu (or the New toolbar icon ),

  2. Select the Anomaly profile icon ,

  3. Enter an Anomaly profile name in the Name edit box.

  4. Click OK.

or

  1. Right-click on the Anomaly Profiles folder in the Anomalies tree,

  2. Select "New Anomaly Profile" from the contextual menu,


  1. A new entry is created in the Anomalies tree (Anomalies tab).


     

  2. Specify a new name for the newly created Anomaly profile.


To Edit an Anomaly profile:

Double-click on an Anomaly profile entry in the tree. The Anomalies profile document is opened in the Job Management window.

The Anomaly profile document is composed of 3 parts:

  1. Available Anomalies: located on the left side, it gives a list of available anomalies,

  2. Anomaly List: located on the top right portion, it gives a list of selected anomalies,

  3. Anomaly Details: located on the bottom right, it gives details about an anomaly selected in the anomalies list.

Available Anomalies:

The list of available anomalies depends on the collector modules installed. They are arranged by category (Http, Unix, Oracle ...).
To add a new anomaly to the anomalies list:

  1. select it in the Available Anomalies tree,

  2. click the icon (on top of the Available Anomalies view),

  3. the selected anomaly is inserted into the Anomalies list.

or

  1. select it in the Available Anomalies tree,

  2. drag and drop it in the Anomalies List,

  3. the selected anomaly is inserted into the Anomalies List.

Anomalies List

The Anomalies List shows the anomalies that may be raised when this Anomaly Profile is applied to a Job result.
Uncheck the check box located on the left side of an anomaly to disable it.

To remove an anomaly from the anomalies list:

  1. select it, then right click
  2. choose "Delete" from the contextual menu or press the Del key
     

Anomaly Details

To change the properties of an anomaly, select it in the Anomalies List. Its properties are shown in Anomaly Details window.


 

Description Description of the anomaly
Enable If false, this anomaly is not taken into account.
Formula Formula used to raise the anomaly:
 
> An anomaly arises if the mean value computed over a time period greater than or equal to the raise time is greater than the threshold.
>= An anomaly arises if the mean value computed over a time period greater or equal to the raise time is greater than or equal to the threshold.
< An anomaly arises if the mean value computed over the time period greater than or equal to the raise time is lower than the threshold.
<= An anomaly arises if the mean value computed over the time period greater than or equal to the raise time is lower than or equal to the threshold.
Increase An anomaly arises if the slope of the trend curve is greater than the threshold.
(the threshold unit is expressed in "Y units per hour, minute or second")
Decrease An anomaly arises if the slope of the trend curve is lower than the threshold.
(the threshold unit is expressed in "Y units per hour, minute or second")
Far from mean This formula is used to detect time periods where values are far from the mean value (computed over the entire duration of the job).

An anomaly arises if the mean value computed over the time period greater than or equal to the raise time is
  • (mean_over_raise_time) > (total_mean_value + (Threshold * total_mean_value))
    or
  • (mean_over_raise_time) < (total_mean_value - (Threshold * total_mean_value))

Thresholds are expressed as a percentage of the total mean value.

Unit The threshold unit
Severity 1 First threshold value
Severity 2 Second threshold value
Severity 3 Third threshold value
Raise Time(s) Time period in seconds used for all formulas except Increase and Decrease

Default values are assigned for each property, but these values can be modified by entering new ones in the right column.
