munin-node.conf - Munin-node configuration file
Munin-node is the node that Munin fetches data from, graphs, htmlifies
and optionaly warns nagios about data it gathers. It's designed to let
it be very easy to graph new datasources.
"munin-node.conf" is the configuration file for munin-node.
The format of the file is dictated by the use of Net::Server. A look at
"perldoc Net::Server" will give a list of options that the file
supports by using the module.
The following options are of special interest:
IP based access list is implemented through this. The statement
may be repeated many times. It's important to note that it's
actually a regular expression after the keyword so to allow
localhost it must be written like this:
The IP number of the interface munin-node should listen on. By
default munin-node listens to all interfaces. To make munin-node
listen only on the localhost interface - making it unavailable
from the network do this:
If set, overrides the hostname munin-node uses in its
'hello'-negotiation with munin. A "telnet localhost 4949" will
show the hostname munin-node is currently using. If munin-node and
the main munin installation do not agree on the hostname, munin
will skip all the plugins of the machine in question.
If set, checks permissions of plugin files, and only tries to run
files owned by root. Default on.
Files matching <regex> in the node.d/ and node-conf.d/ directories
will be overlooked.
Can have four values. "paranoid", "enabled", "auto", and
"disabled". "Paranoid" and "enabled" require a TLS connection,
while "disabled" will not attempt one at all.
The current default is "disabled" because "auto" is broken.
"Auto" causes bad interaction between munin-update and munin-node
if the node is unprepared to go to TLS.
If you see data dropouts (gaps in graphs) please try to disable
This directive can be "yes" or "no". It determines if the remote
certificate needs to be signed by a CA that is known locally.
Default is "no".
This directive sets the location of the private key to be used for
TLS. Default is @@CONFDIR@@/munin-node.pem. The private key and
certificate can be stored in the same file.
This directive sets the location of the TLS certificate to be used
for TLS. Default is @@CONFDIR@@/munin-node.pem. The private key
and certificate can be stored in the same file.
This directive sets the CA certificate to be used to verify the
node's certificate, if tls_verify_certificate is set to "yes".
Default is @@CONFDIR@@/cacert.pem.
This directive sets how many signings up a chain of signatures TLS
is willing to go to reach a known, trusted CA when verifying a
certificate. Default is 5.
This directive, if defined, searches a dump of the certificate
provided by the remote host for the given regex. The dump of the
certificate is two lines of the form:
Subject Name: /C=c/ST=st/L=l/O=o/OU=ou/CN=cn/emailAddress=email
Issuer Name: /C=c/ST=st/O=o/OU=ou/CN=cn/emailAddress=email
So, for example, one could match the subject distinguished name by
tls_match Subject Name: /C=c/ST=st/L=l/O=o/OU=ou/CN=cn/emailAddress=email
Note that the fields are dumped in the order they appear in the
certificate. It's best to view the dump of the certificate by
running munin-update in debug mode and reviewing the logs.
Unfortunately, due to the limited functionality of the SSL module
in use, it is not possible to provide finer-grained filtering. By
default this value is not defined.
A pretty normal configuration file:
