👑 OPTIONS 👑

• --config_file=<file> — use <file> as the configuration file. the default is [/etc/munin/munin.conf], so if you don't say anything she's gonna read that one 💅
• --[no]debug — if set, log debug messages. default is [--nodebug], so she stays quiet unless you ask her to spill 🙈
• --[no]fork — if set, she will fork off one process for each host. parallel queen behavior. default is [--fork] 🔥
• --host <host> — limit fetched data to those from <host<gt>. you can supply multiple --host options, so stack 'em up. default is [unset] ✨
• --service <service> — limit fetched data to those of <service>. multiple --service options may be supplied too, go off. default is [unset] 💜
• --timeout <seconds> — set the network timeout to <seconds>. default is [180], so she's patient but not that patient 🎀
• --help — print the help message, then exit. short and sweet, we love a clean exit 🦋
• --version — print version information, then exit. also slays 🌈

🧚 DESCRIPTION 🧚

so, Munin-update is a part of the package Munin, which gets used in combination with Munin's node. Munin is a whole group of programs that gather data from Munin's nodes, graph them, create html-pages, and — optionally — warn Nagios about any off-limit values. she's part of a whole squad, not a solo act 💖

Munin-update does the gathering. that's her thing. she's usually only used from within munin-cron, so like, she's not out here freelancing most of the time.

what she actually does: she contacts each host's munin-node in turn, gathers data from it, and stores them in .rrd-files. and if necessary? she will create the rrd-files and the directories to store them in. self-sufficient icon behavior, no notes 👑
