This report provides detailed storage statistics and the evolution of the storage space of your IT infrastructure.
How to interpret the report
The first page displays overall information about allocated and used space for host groups. A graph traces the past evolution of these two parameters. Two tables list the most critical information for hosts in terms of storage space.
On the second and third pages, statistics for allocated and used space are organized by service category and host category.
The fourth page shows storage space per host group, with the allocated and used space for each partition, the evolution over the last month, and estimated time before saturation.
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 comparing 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 this report:
- The reporting period
- The following Centreon objects:
|Host group||Dropdown list||Select host group.|
|Host categories||Multi select||Select categories.|
|Service categories||Mutli select||Select storage service categories.|
|Metrics||Mutli select||Metric to exclude from the list.|
|Time period||Dropdown list||Specify time period. /!Only the timeperiod 24x7 should be used /!|
|Theme||Dropdown list||Select theme.|
|Intervalle||Text field||Specify no. of months for evolution graphs.|
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”
