# 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/cache/munin/www
#logdir /var/log/munin
#rundir  /var/run/munin

# Where to look for the HTML templates
#
#tmpldir        /etc/munin/templates

# Where to look for the static www files
#
#staticdir /etc/munin/static

# temporary cgi files are here. note that it has to be writable by
# the cgi user (usually nobody or httpd).
#
# cgitmpdir /var/lib/munin/cgi-tmp

# (Exactly one) directory to include all files from.
includedir /etc/munin/munin-conf.d

# You can choose the time reference for "DERIVE" like graphs, and show
# "per minute", "per hour" values instead of the default "per second"
#
#graph_period second

# Graphics files are generated either via cron or by a CGI process.
# See http://munin-monitoring.org/wiki/CgiHowto2 for more
# documentation.
# Since 2.0, munin-graph has been rewritten to use the cgi code.
# It is single threaded *by design* now.
#
#graph_strategy cron

# 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 /munin-cgi/munin-cgi-graph

# max_size_x and max_size_y are the max size of images in pixel.
# Default is 4000. Do not make it too large otherwise RRD might use all
# RAM to generate the images.
#
#max_size_x 4000
#max_size_y 4000

# HTML files are normally generated by munin-html, no matter if the
# files are used or not. You can change this to on-demand generation
# by following the instructions in http://munin-monitoring.org/wiki/CgiHowto2
#
# Notes:
# - moving to CGI for HTML means you cannot have graph generated by cron.
# - cgi html has some bugs, mostly you still have to launch munin-html by hand
#
#html_strategy cron

# munin-update runs in parallel.
#
# The default max number of processes is 16, and is probably ok for you.
#
# If set too high, it might hit some process/ram/filedesc limits.
# If set too low, munin-update might take more than 5 min.
#
# If you want munin-update to not be parallel set it to 0.
#
#max_processes 16

# RRD updates are per default, performed directly on the rrd files.
# To reduce IO and enable the use of the rrdcached, uncomment it and set it to
# the location of the socket that rrdcached uses.
#
#rrdcached_socket /var/run/rrdcached.sock

# Drop somejuser@fnord.comm and anotheruser@blibb.comm an email everytime
# something changes (OK -> WARNING, CRITICAL -> OK, etc)

# The maximum time the munin-update may take to get updates from all nodes,
# this might be interesting when using munin-async in case of large transactions and/or backlog.
# When using the munin protocol to connect to a node, then this value shouldn't be set higher than 240.
# In case it's higher, gaps might be seen in the graphs.
timeout_fetch_all_nodes 240

# The maximum amount of time in seconds we may work on 1 node.
# The value will be limited with timeout_fetch_all_nodes.

#
# A more complex example of a host tree
#
## First our "normal" host.
# [fii.foo.com]
#       address foo
#
## Then our other host...
# [fay.foo.com]
#       address fay
#
## IPv6 host. note that the ip adress has to be in brackets
# [ip6.foo.com]
#       address [2001::1234:1]
#
## Then we want totals...
# [foo.com;Totals] #Force it into the "foo.com"-domain...
#       update no   # Turn off data-fetching for this "host".
#
#   # The graph "load1". We want to see the loads of both machines...
#   # "fii=fii.foo.com:load.load" means "label=machine:graph.field"
#       load1.graph_title Loads side by side
#       load1.graph_order fii=fii.foo.com:load.load fay=fay.foo.com:load.load
#
#   # The graph "load2". Now we want them stacked on top of each other.
#       load2.graph_title Loads on top of each other
#       load2.dummy_field.stack fii=fii.foo.com:load.load fay=fay.foo.com:load.load
#       load2.dummy_field.draw AREA # We want area instead the default LINE2.
#       load2.dummy_field.label dummy # This is needed. Silly, really.
#
#   # The graph "load3". Now we want them summarised into one field
#       load3.graph_title Loads summarised
#       load3.combined_loads.sum fii.foo.com:load.load fay.foo.com:load.load
#       load3.combined_loads.label Combined loads # Must be set, as this is
#                                                 # not a dummy field!
#
## ...and on a side note, I want them listen in another order (default is
## alphabetically)
#
# # Since [foo.com] would be interpreted as a host in the domain "com", we
# # specify that this is a domain by adding a semicolon.
# [foo.com;]
#       node_order Totals fii.foo.com fay.foo.com
#
