Initial Configuration¶
Node¶
Plugins¶
Decide which plugins to use. The munin node runs all plugins present in CONFDIR/plugins/ (usually /etc/munin/plugins).
The quick auto-plug-and-play solution:
munin-node-configure --shell --families=contrib,auto | sh -x
See Using munin plugins for more details.
Access¶
The munin node listens on all interfaces by default, but has a
restrictive access list. You need to add your master’s IP address
to /etc/munin/munin-node.conf.
The cidr_allow, cidr_deny, allow and deny directives
are related to access control.
cidr_allow expects the following notation:
syntax (the /32 is not implicit, so for
a single host, you need to add it):
cidr_allow 127.0.0.0/8cidr_allow 192.0.2.1/32
Please note, that the prefix length (e.g. /32) is mandatory for
cidr_allow and cidr_deny.
allow uses regular expression matching against the client IP address.
allow ‘^127.’allow ‘^192.0.2.1$’
For specific information about the syntax, see Net::Server. Please
keep in mind that cidr_allow requires the Net::CIDR perl module.
Startup¶
Start the node agent (as root) SBINDIR/munin-node. Restart it if it was already started. The node only discovers new plugins when it is restarted.
You probably want to use an init-script instead and you might find a good one under build/dists or in the build/resources directory (maybe you need to edit the init script, check the given paths in the script you might use).
