Event macros can be initiated not only by events of a particular type (see Configuring start conditions), but also by statistical parameters.

A macro can be started by the following parameters reaching pre-defined criteria:

1. Archive usage.
2. Disk usage.
3. Memory usage.
4. Network usage.
5. CPU usage.

To configure the start of macros by statistics, do the following:

1. Select the required parameter from the Start conditions list in the Statistics group.
   

2. In the Parameter (1) field, set a specific parameter.
   

   Archive usage	Archive in the following format: hosts/TEST/MultimediaStorage.AliceBlue/MultimediaStorage (see Get archive contents)
   Disk usage	TEST@C:\, where TEST is the name of a Server within the Axxon-domain, C:\ is the volume name. Attention You cannot monitor storage capacity of a disk fully allocated for the archive (see Creating a local archive)
   Memory usage	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 the Leaving condition, enter the range into the Delta (3) field (see step 5).

5. From the Trend (4) list, select a trend to start a macro.

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

   The macro starts only when events that meet the start conditions occur in the future. For example, if the current CPU usage is 85%, and you specified the macro to start when the threshold of 80% is exceeded, the macro starts only when the threshold of 80% is exceeded next time.

6. If necessary, you can set several event and/or statistical conditions to start a macro.
