Goal: This report diplays statistics on allocated and used storage space, for hostgroups, filtred by host categories and service categories.
How to interpret the report?
Global statistics are displayed on the two first pages.
On the first page, statistics aggregated by hostgroup are displayed.
On the second one, statistics are displayed by Host Categories and Service Categories.
On the next pages, all global statistics are detailed for each hostgroup, with the repartition by host categories and service categories.
For each host group¶
Statistics displayed in evolution tables and graphs by months correspond to values of indicators measured the last day of concerned months. « Snapshot » statistics ( versus evolution statistics by month ) correspond to values of indicators measured the last day of the reporting period. When an evolution calculation is done, it is calculated comparing values of indicators the last day of the reporting period and the values of indicators the day before the first day of the reporting period.
Parameters needed by report are:
- The reporting period
- The following Centreon object:
|Hostgroups||Multi select||Selection of hostgroups|
|Host Categories||Multi select||Selection of host Categories to use|
|Services Categories||Multi select||Selection of host Categories to use|
|Metric names||Multi select||Metric to exclude from the report|
|Time period||Dropdown list||Time period to report. /!Only the timeperiod 24x7 should be used /!|
|Evolution interval||Text field||Number of historical months for the evolution graphics|
To ensure consistency some prerequisites are necessary regarding to performance data returned by plugins.
Performance data are data returned by a plugin after the “pipe” - “|” , these data have to be returned as follow:
output-plugin | metric1=valueunit;warning_treshold;critical_treshold;minimum;maximum metric2=value. . .
It is important to make sure that plugins return the maximum value because lot of statistics are based on percentage, calculated using this maximum value. Be sure that the storage plugins and memory plugin return this maximum value. The unit must be Bytes.
This report is compatible with the timeperiod 24x7 only. This timeperiod have to be configured on the menu “General options | Capacity statistic agregated by month | Live services for capacity statistics calculation”
