Munin
Networked resource monitoring for performance insights and real-time alerts
About Munin
Munin is a plug-and-play monitoring tool that tracks server and network performance, providing historical data and real-time alerts. With over 500 plugins and support for custom scripts, it scales from single machines to large clusters. Built on Perl and RRDTool, Munin delivers actionable insights through an intuitive web interface.
FAQ
Munin supports Linux, FreeBSD, NetBSD, Solaris, AIX, OS X/Darwin, and HP-UX. It is programmed in Perl, which can be installed on most operating systems, but some plugins are OS or application-specific.
You need a reasonable Perl5 installation, RRD with Perl support, and specific Perl modules for the server (Time::HiRes, Storable, Digest::MD5, HTML::Template, Text::Balanced) and node (Net::Server). Some plugins may require additional modules.
You can override plugin settings in munin.conf by specifying the plugin name, field name, and the new value. For example, to set the warning level for the df plugin on /home to 98%, use: [foo.example.com] address 10.20.30.40 df._home.warning 98.
In your munin.conf file, set graph_period to minute for the host and plugin. For example: [server.example.com] address 10.0.0.1 postfix_mailstats.graph_period minute.
Yes, you can configure the node to use an SSH tunnel. Set the node's address to 127.0.0.1 and port to 5050, then use ssh to establish the tunnel. For example: ssh -L 5050:localhost:4949 -f -N -i keyfile user@ssh-node.
Replace the dot with an underscore in the service name. For example, if the service name is ip_192_168_199_23, use uakari_net.graph_order in=uakari.example.org:ip_192_168_199_23.in.
Use the domain_order option to change the order of domains and the node_order option under a domain to change the order of nodes. For example: [] domain_order foo.bar goo.bar alpha.bar or [foo.bar;] node_order fii.foo.bar bing.foo.bar goo.foo.bar.
A minimal server configuration should include paths for dbdir, htmldir, logdir, and rundir, and at least one host definition with its address. For example: dbdir /var/lib/munin htmldir /var/www/munin logdir /var/log/munin rundir /var/run/munin [bing.foo.bar] address 10.232.33.259.
