Hostgroup-Capacity-Planning-Linear-Regression

Description

Goal:

This report displayed the evolution and forecast of performance metrics, for a hostgroup

How to interpet the report?

The metrics value evolution is displayed on a graph and a table. Forecasts are calculated from the reporting period metrics value, and projected in the futur. Another table gives information about metrics progression and days before saturation.

Parameters

Parameters needed by report are:

• The reporting period

• The following Centreon object:

Parameter	Parameter type	Description
Host groups	Multi select	Host groups to filter on
Host Categories	Multi select	Selection of host Categories to filter on
Services Categories	Multi select	Selection of service Categories to filter on
Time period	Dropdown list	Time period to report.
Metrics	Multi select	Metric to include in the report
Historical period in days in addition of the reporting period	Number	Days used to calcutate the linear regression in addition to the reporting period
Forecast period in days	Number	Forecast days calculated by linear regression

Prerequisites:

Metrics must return a max value on their performances data. Using Warning and critical thresholds on performances data is highly recommanded

Performance data are data returned by a plugin after the “pipe” - “|” , these data have to be returned as follow:

output-plugin | metric1=valeur(unité);seuil_warning;seuil_critique;minimum;maximum metric2=valeur . . .
