- The time range of the report. Use the Start Beginning date, Start Beginning time, Stop End date, and Stop End time fields.
- Object description. You can use this field to choose between two report modes:
- Report on all the system objects.
- Report on one system object.
- Take into account the Include number of cameras on site. If you select this check box, the non-readiness rates for the cameras and archives are calculated taking into account all the cameras of the object.
- Take into account Include archive errors. If you select this check box, the non-readiness rates for the the whole system are calculated taking into account the non-readiness rates for the archives.
- Show alarms. If you select this check box, alarm information from the object(s) is added to the report.
- If you set the Object description parameter to All objects, you can edit the Detailed report parameter. If you do NOT select this check box, a generalized statistical report on the system is created.
If you select the Detailed report check box, then Sorting, Sort, and Readiness rate Availability factor threshold parameters become available. In this case, a detailed statistical report on the system is created. - Sorting. This field allows you to sort statistical data by certain criteria.
- Sort. Use this field to set the sort order (ascending or descending).
- If you select the Readiness rate Availability factor threshold check box, the Threshold Value (%) and Condition fields become available. Use this fields to sort objects by an additional condition, the threshold for the readiness rate.
- Threshold Value (%). Use this field to set a threshold (between 0 and 100 %).
- Condition. Use this field to set an object filtering condition: Below lower than threshold or Above higher than threshold.
- If you set the Object description field to a certain object, you can edittheAlarm details and Failure details edit the Provide info about alarms and Provide info about failures parameters. Select these check boxes if you want to include detailed information on failures and alarms in the report.

This example uses the time period from 12 a.m. on February 1, 2005, to 12 p.m. on February 28, 2005, to create a statistical report. The readiness rate of an object is calculated as a ratio between the duration of the time period when the object was functioning and the duration of the time period used for the report:
Rr = Taf/(Taf+Tuf)
The following types of failure are used for reports:
...
Connection non-readiness:
Rn_c = (Tuf_net_1 + Tuf_net_2)/(Taf+Tuf)
Software non-readiness:
Rn_sw = Tuf_soft/Taf+Tuf
Camera non-readiness:
Rn_cam = Tuf_cam/Taf+Tuf
Generally, in this model, the non-readiness rate Rn is not equal to the sum of all the non-readiness rates for all failures.
