Chart management
Centreon can be used to generate graphs from monitoring information. There are two types of graph:
- Performance graphs serve to view the evolution of services intuitively. Example: filling level of a hard disk, network traffic, etc.
- History graphs (or status graphs) are used to view the evolution of the statuses of a service.
Performance graphs always have a time period for the x-axis and a unit as the y-axis (volts, bytes, etc.). History graphs always have a time period for the x-axis, and their y-axes do not vary. Only the color of the graph can be used to view the status of the object:
- Green for OK status
- Orange for WARNING status
- Red for CRITICAL status
- Gray for UNKNOWN status
Example of performance graph:
Performance graphs
There are several ways to view performance graphs:
- Viewing the graph in the list of services, from Monitoring > Status Details > Services menu, by mouseover on the icon
- Viewing the graphs from the host' detail page by clicking View graphs for host
- Viewing the graph from the service details page
- From the Monitoring > Performances > Graphs menu to view multiple graphs
Status graphs
In the same way as for the performance graphs, there are several ways of accessing status history graphs:
- From the service' details page
- From the Monitoring > Performances > Graphs menu, by first selecting a specific service.
Viewing multiple graphs
To view all graphs, go to the Monitoring > Performances > Graphs menu.

Several actions are possible on the page:
- To refresh the data manually by clicking the icon
- To automatically refresh the data by clicking the icon and by selecting a predefined period

Several actions are possible on each graph:
