Viewing Historical Data

To view collected (historical) data, take these steps:
1. Select the Display Historical PMs option in the Performance Monitoring menu;
the 'History PM' screen opens.
2. Continue (as needed) to select entities to be added to the same screen. All
entities must be of the same type (trunks, or System Controller boards, or Media
Gateways of the same control protocol type). After all entities are selected, select
the parameter to view by pressing the Parameters Filter button. Only
parameters available for that entity type are displayed for selection.
Note that you can select up to 15 parameters. Note that the number of entities
you can select is unlimited.
3. Select the Time Interval according to which you need to review data and click
Refresh. After data is displayed, you can save it as a .csv file by clicking the
Save icon. Historical data comprises two tables: The uppermost table displaying
detailed data (in user-defined intervals) and the table below it displaying
summarized data. Each time a sample is taken from the media gateway, it is
stored in the detailed table, where the entity name and index, parameter name,
start, stop polling time and parameter value are specified. After every 24 hours of
sampled data, the detailed table is summarized. For each entity and parameter,
the start and stop summary time is stored and the average, minimal and maximal
value is displayed. Detailed data is stored for a period of 7 days (in intervals of 15
minutes). Historical data is stored for 30 days (in intervals of 24 hours). Data
storage time is dependent on available disk space.
