1. The percentage of used space in Archive.
2. The percentage of used space on a volume.
3. The percentage of used RAM on a Server.
4. The percentage of used network bandwidth on a Server.
5. The percentage of CPU load on a Server.

In addition, you can run event-driven macro when video footage recording is broken or restored.

To set up triggering macros by statistics, do as follows:

1. Select the desired parameter from the Start Conditions list in the Statistics group.

2. Enter the parameter definition into the Item Parameter (1) field.

   Archive usage	Archive in the following format: hosts/SERVER1TEST/MultimediaStorage.AliceBlue/MultimediaStorage,.
   Disk usage	SERVER1@CTEST@C:\ ,where SERVER1 TEST is the name of a server Server within the Axxon-domain, C:\ is the volume name. Important! You cannot monitor storage capacity of a disk fully allocated for Archive.
   Memory usage (RAM)	The name of a server within the Axxon-domain.
   Network usage	The name of a server within the Axxon-domain.
   CPU usage	The name of a server within the Axxon-domain.

   
   

3. Enter the threshold value into the Value (2) field.
4. For  Leaving Leaving condition, enter the range into the Delta (3) field (see section 5).Enter the threshold value into the Value (2) field.

5. From the Trend (4) list, select a triggering condition for the macro.

   Leaving	The macro is triggered if a parameter value goes out of the specified range [Value -  – Delta; Value].
   Rising	The macro is triggered if the parameter value exceeds the threshold specified in the Value field.
   Falling	The macro is triggered if the parameter value falls behind the threshold specified in the Value field.

   
   

   Note
   title Attention!
   The triggering conditions are set not for current but for future events. For instance, if the current CPU load is 85%, and you set the triggering condition to exceeding 80%, the macro will be launched only when the CPU load exceeds 80% value next time.

   
   

6. If necessary, you can set several event and/or statistical conditions for triggering macros.  

To set up macros that run when recording halts or resumes, do as follows:

1. Select the No recording to archive parameter from the Start conditions list in the Statistics group (1).

   In the  Stream list, select the stream to track uninterrupted recording (2). Feel free to select all the streams from a group of video cameras. In this case, the macro will start when any stream from the group selected above is interrupted or restored.

   title Note
   Get list of video sources (cameras).

2. Select the trigger for a macro:  recording interrupted or resumed (3).
3. If necessary, you can set several event and/or statistical conditions that will trigger macros.
