This report displays statistics on allocated and used storage space for multiple host groups.
How to interpret the report
On the first page, statistics are summarized by host group.
On the second page, statistics are displayed by host category and service category.
On the following pages, overall statistics are detailed for each host group, displayed by host categories and service categories.
For each host group¶
Statistics displayed in evolution tables and graphs by month correspond to values of indicators measured on the last day of the month. “Snapshot” statistics (versus evolution statistics by month) correspond to values of indicators measured the last day of the reporting period. Evolution calculations are based on a comparison of the values of indicators the last day of the reporting period with the values of indicators the day before the first day of the reporting period.
Parameters required for the report:
- Reporting period
- The following Centreon objects:
|Hostgroups||Multi select||Select the host groups.|
|Host Categories||Multi select||Select the host categories.|
|Services Categories||Multi select||Select host categories|
|Metric names||Multi select||Specify metric to exclude from the report.|
|Time period||Dropdown list||Specify time period to report. /!Only the timeperiod 24x7 should be used /!|
|Evolution interval||Text field||Specify number of historical months for the evolution graphics.|
For consistency in graphs and statistics, certain prerequisites apply to performance data returned by the storage plugins. This data must be formatted as follows, preceded by a pipe (|):
output-plugin | metric1=valueunit;warning_treshold;critical_treshold;minimum;maximum metric2=value...
Make sure that the plugins return the maximum value, which is required in order to calculate statistics. The unit must be expressed in bytes.
The ETL configuration must include service categories for storage, otherwise the evolution graphics remain empty.
This report is compatible with the 24x7 time period only. This time period must be configured on the menu “General options | Capacity statistic aggregated by month | Live services for capacity statistics calculation”.
