| # Example configuration file for Munin, generated by 'make build' # The next three variables specifies where the location of the RRD # databases, the HTML output, logs and the lock/pid files. They all # must be writable by the user running munin-cron. They are all # defaulted to the values you see here. # dbdir /var/lib/munin htmldir /var/www/munin logdir /var/log/munin rundir /var/run/munin # # Where to look for the HTML templates # tmpldir /etc/munin/templates # (Exactly one) directory to include all files from. # includedir /etc/munin/munin-conf.d # Make graphs show values per minute instead of per second #graph_period minute # Graphics files are normaly generated by munin-graph, no matter if # the graphs are used or not. You can change this to # on-demand-graphing by following the instructions in # http://munin.projects.linpro.no/wiki/CgiHowto # #graph_strategy cgi # munin-cgi-graph is invoked by the web server up to very many times at the # same time. This is not optimal since it results in high CPU and memory # consumption to the degree that the system can thrash. Again the default is # 6. Most likely the optimal number for max_cgi_graph_jobs is the same as # max_graph_jobs. # #munin_cgi_graph_jobs 6 # If the automatic CGI url is wrong for your system override it here: # #cgiurl_graph /cgi-bin/munin-cgi-graph # munin-graph runs in parallel, the number of concurrent processes is # 6. If you want munin-graph to not be parallel set to 0. If set too # high it will slow down munin-graph. Some experiments are needed to # determine how many are optimal on your system. On a multi-core # system with good SCSI disks the number can probably be quite high. # #max_graph_jobs 6 # Drop somejuser@fnord.comm and anotheruser@blibb.comm an email everytime # something changes (OK -> WARNING, CRITICAL -> OK, etc) #contact.someuser.command mail -s "Munin notification" somejuser@fnord.comm #contact.anotheruser.command mail -s "Munin notification" anotheruser@blibb.comm # # For those with Nagios, the following might come in handy.
