The Event Graph Dashlet allows you to view the events (changes of state) generated within
Opsview Monitor in a Dashlet format. This table is a smaller version of the bar
chart within the ‘Events Viewer’ section of ‘Monitoring’:
The Dashlet will display, by default, data from the last six hours, for
all events generated within the Opsview Monitor system. To see what the events
are, simply click on a section, i.e. the ‘Red bar’ above with the ‘9’ value in
it, will load a new modal window, as shown below, displaying those 9 CRITICAL events:
Unlike in the main ‘Event Viewer’ section within ‘Monitoring’, only one
bar can be selected at a time.
The Event Graph Dashlet has a range of filters, exactly the same as the
Event Table Dashlet, which allows you to filter the events displayed on the
Event Graph by a range of different ways, as per the settings modal window for
You can choose to filter the Events Graph to show events that have
occurred within specific Business Services, Components, Host Groups, Hashtags,
Hosts, Host Templates or Service Checks – and also filter the events based on
their state, i.e. only show CRITICAL events, or only show ‘HARD’ events, etc.
These filters are applied using an ‘AND’ logic, i.e. ‘Only show events within
“Host Group A”, on Hosts “B” and “C”, only within the Host Template “Unix Base”,
and only show CRITICAL events, that are in a HARD state”.
Finally, you can also choose to define a different timeframe from the
default ‘6 hours’, with options for ‘3 hours’, ‘6 hours’, ‘1 day’, ‘2 days’.
