munin-graph

DESCRIPTION

munin-graph script is one of the munin master components run from the munin-cron script.

If “graph_strategy” is set to “cron”, munin-graph creates static graphs from all RRD files in the munin database directory.

If graph_strategy is set to “cgi”, munin-graph will not create graphs. This is the proper setting when you run munin-httpd.

OPTIONS

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

--fork

By default munin-graph forks subprocesses for drawing graphs to utilize available cores and I/O bandwidth. Can be negated with –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]

--lazy

Only redraw graphs when needed. Can be negated with –nolazy [–lazy]

--host <host>

--only-fqn <FQN>

For instance: –only-fqn root/Backend/dafnes.example.com/diskstats_iops

Always use with the correct –host option.

--config <file>

--output-file | -o

--size_x <pixels>

Sets the X size of the graph in pixels [175]

--size_y <pixels>

Sets the Y size of the graph in pixels [400]

--lower_limit <lim>

Sets the lower limit of the graph

--upper_limit <lim>

--pinpoint and --only-fqn must not be combined with any of --day, --week, --month or --year (or their negating forms). The result of doing that is undefined.
