Graphs

Definition

SIPMon utilizes monitoring data to generate visual graphs, providing key insights into system metrics. There are two primary categories of graphs available:

Performance Graphs

Performance graphs allow for the intuitive visualization of service evolution over time. These graphs are essential for tracking metric-based data.

• Examples: Hard disk capacity usage, network traffic volume, etc.
• Structure:
  • X-axis: Time period.
  • Y-axis: Unit of measurement (e.g., Volts, Octets).

History Graphs (Status Graphs)

History or Status graphs display the chronological evolution of a service's status. Unlike performance graphs, the vertical axis does not represent a variable magnitude but rather the state of the service.

• Structure:
  • X-axis: Time period.
  • Y-axis: Constant.
• Status Indicators: The status of the monitored object is indicated by color-coded segments:
  • Green: OK status
  • Orange: WARNING status
  • Red: CRITICAL status
  • Grey: UNKNOWN status

Visualization

Performance Graphs

There are several ways to view Performance Graphs:

• Viewing the graph in the list of services (Monitoring → Services) by mouse-over the icon .
• Viewing the graph from the page of details of an object by clicking on View graphs for host.
• Go into the menu: Monitoring → Performances 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 detail page of an object (see the chapter covering real time monitoring)
• From the menu: Monitoring → Performances, by first selecting a specific service and then checking the Display Status box

Viewing Multiple Graphs

To view all graphs, go into the menu: Monitoring → Performances

• All the filters on the top of the page allow selecting the graph one wants, for a time period one wishes to.
• The option Hosts show all graphs to all hosts linked.
• The option Services show only graphs of the selected services
• The option Graph Period can be used to select the time period over which one wishes to view the graphs. The drop-down list can be used to select predefined time periods.
• It is possible to choose the time period manually, using the fields, from and to: this replaces the predefined selection.

Actions Possible on the Graphs

• Split components: separates multiple curves of a graph into multiple graphs each containing one curve.
• Display Status: Displays the history graphs linked to performance graphs displayed.
• To use the data from graphs, it is possible to:
  • View the performance graphs on a daily, weekly, monthly or yearly basis by clicking on the performance graphs of your choice.
  • Zoom in on the graphs by clicking on the icon
