DESCRIPTION

The munin-graph script is run by munin-cron, and creates graphs from all RRD files in the munin database directory.

OPTIONS

Some options can be negated by prefixing them with “no”. Example: –fork and –nofork

--fork

--n <processes>

Max number of concurrent processes [6]

--force

Force drawing of graphs that are not usually drawn due to options in the config file. Can be negated with –noforce [–noforce]

Sets the lower limit of the graph

--upper_limit <lim>
