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 image
  • 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.
