Since Xymon v4.3.20 it is possible to configure the rrd-graphs shown on
individual status pages. In previous versions it was only possible to configure
this for the
trends-column and the (single) graph on the status columns was
hard coded into Xymon.
To change (replace or extend) the graphs shown on the status-columns add
This setting overrides the default graph for the column, so that has to be
included in the configuration if just an additional graph should be shown.
The default for the
cpu column is to show the load graph
la. If we want to
show a detailed CPU-usage graph with I/O-wait along with the standard graph
we can add
xymonserver.cfg. No need to restart anything, the changes are picked up on
the next refresh/reload of the status display2.
Adding even more graphs is possible, i.e.
Another handy example: Show apache-statistics on the
data is collected by the
apache=http://127.0.0.1/server-status?auto. The following adds all available
apache-graphs to the http-status column.
To save your from checking
graphs.cfg here the contents of the 4 graphs:
- apache: Utilization (total accesses, kBytes tranferred)
- apache1: Workers (busy, idle)
- apache2: CPU utilisation
- apache3: Requests per second
Adding graphs also works for custom status columns of course.
It does not work for the (kind of virtual)
info column nor is it possible
to create new “graph only” columns.
