This report shows the average bandwith usage distibution of network interfaces, for a given hostgroup.
How to interpret the report?
On the first page, we can see the bandwidth usage ranges in percent by interval.
- Null usage
- Low usage
- Average usage
- High usage
- Very high usage
These intervals are configurable.
The next pages are automatically generated for all interfaces of the selected hostgroup ( one page per interface). Each page dispays the bandwidth usage by inetrval with a repartition by:
- Hour of the day
- Day of the week
- Day of the month
Parameters needed by the report are :
- The reporting perriod.
- The following Centreon objects :
|Groupe d’hôtes||Dropdown list||Host group to use|
|Host Categories||Multi select||Host categries to use|
|Service Categories||Multi select||Service categories to use|
|Low level treshold (%)||Number||Low threshold of bandwidth usage (between 0 and 100)|
|Average level threshold (%)||Number||Average threshold of brandwidh usage (between 0 and 100)|
|High level threshold (%)||Number||High threshold of brandwidh usage (between 0 and 100)|
|Inbound traffic metric||Dropdown list||Metric name of the inbound traffic|
|Outbound traffic metric||Dropdown list||Metric name of the outbound traffic|
To ensure consistency in graphs and statistics, 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 | traffic_in=valueunit;warning_treshold;critical_treshold;minimum;maximum traffic_out=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 traffic plugins return one metric for traffic in and one for traffic out. The unit must be Bits/sec.
