23.6. Status history and statistics

PSM displays various statistics and status history of system data and performance on the dashboard at Basic Settings > Dashboard. The dashboard is essentially an extension of the system monitor: the system monitor displays only the current values, while the dashboard creates graphs and statistics of the system parameters.

The dashboard consists of different modules. Every module displays the history of a system parameter for the current day. To display the graph for a longer period (last week, last month, or last year), select the Week, Month, or Year options, respectively. Hovering the mouse over a module enlarges the graph and displays the color code used on the graph.

All types of data is collected every five minutes. This means that if changes are more frequent, it might not be represented in the graphs.

Note

If all parameters displayed are 0 at a certain point in time, it might mean that at that time PSM was not functional (for example, turned off or unresponsive). Or, in certain cases it might also mean that there was no information at that time.

Note

If you want to compare data displayed on the Dashboard to data displayed on the System Monitor, they might be different, because data on System Monitor is based on SNMP values, whereas data on the related Dashboard modules are based on the output of different commands.

To display statistics of a module as a table for the selected period, click on the graph.
