Munin graphs not updating
In /etc/munin/plugin-conf.d/munin-node add something like: graph_title Counting things graph_vlabel Amount GAUGE total.label Total GAUGE other.label Other Things that do not fall into other categories AREA other.colour 336655 If it doesn't work, then you've probably done the same thing I did: just made sure the HTML produced by munin's cron job is served. Munin is a networked resource monitoring tool that can help analyze resource trends and bottlenecks.If you thought you had set up a NOPASSWD sudo line to avoid this, usually it means it is getting run at a different user, e.g. Also, sudo somewhat-recently decided to be more strict about this, because not having a tty means you can't disable echo(ing the password).
A data source consists of: rrdtool graph /var/stat/img/\ -w 200 --title "Load average" -E -l 0 -u 1 -s -86400 \ DEF:o=/var/stat/data/load1.rrd:load1: AVERAGE \ DEF:t=/var/stat/data/load15.rrd:load15: AVERAGE \ CDEF:od=o,100,/ \ CDEF:td=t,100,/ \ AREA:td#99999977:"15-minute" \ LINE1:od#664444:"1-minute" cd /etc/munin/plugins ln -s /usr/libexec/munin/plugins/ip_ ip_eth0 ln -s /usr/libexec/munin/plugins/ip_ ip_eth1 ln -s /usr/libexec/munin/plugins/ping_ ping_192.168.0.1 ln -s /usr/libexec/munin/plugins/ntp_ ntp_192.168.0.1 Sometimes it helps to run a specific plugin, e.g.
to know which log lines are interesting, or to see if it fails even then.
It's not uncommon for things behave differently when run by the system versus run by you, so you want munin to run the command just as it usually would, because it can matter Just that: sudo needs to ask for a password, and it's not on a terminal so it cannot.
It is worth mentioning that the 2.1.x series will no longer use Fast CGI and will be replaced with munin-httpd This page already contains an example configuration.
Munin is a popular open source network resource monitoring tool which polls the hosts on your network for statistics for various services, resources and other attributes.
