MUNIN-GRAPH

munin-graph script is one of the munin master components run from the munin-cron script. If “graph_strategy” is set to “cron”, munin-graph creates static graphs from all RRD files in the munin database directory. If graph_strategy is set to “cgi”, munin-graph will not create graphs. This is the proper setting when you run

munin-httpd.

MUNIN-CRON — MUNIN 2.999.10-DETACHED-2018-12-16-C13 DESCRIPTION¶. Munin-cron is a part of the package Munin, which is used in combination with munin-node.. Munin is a group of programs to gather data from Munin’s nodes, graph them, create html-pages, and optionally warn Nagios about any off-limit values. MUNIN.CONF — MUNIN 2.999.10-DETACHED-2018-12-16-C13 This is the configuration file for the munin master. It is used by munin-update, munin-limits and munin-httpd. Location in packages is usually /etc/munin/ while if compiled from source it is often found in /etc/opt/munin/. Group and host sections are defined by declaring the group or host name in brackets.

USING MUNIN PLUGINS

The utility munin-node-configure is used by the Munin installation procedure to check which plugins are suitable for your node and create the links automatically. It can be called every time when a system configuration changes (services, hardware, etc) on the node

TROUBLESHOOTING

Check data collection ¶. This step will tell you whether munin-update (the master) is able to communicate with munin-node (the agent). Run munin-update as user munin on the Munin master machine. You should get a line like this: After this, replace df with the service you want to check, such as hddtemp_smartctl.

USING SNMP PLUGINS

Using SNMP plugins¶ (Cribbed from an e-mail written by Rune Nordbøe Skilingstad) The easy way to configure SNMP plugins in Munin is to use munin-node-configure..

Set to 1024 for things that are counted in binary units, such as memory (but not network bandwidth). Set to 1000 for default SI units--units-exponent ¶.

PLUGIN REFERENCE

Plugin reference ¶. Plugin reference. When a plugin is invoked with “config” as (the only) argument it is expected to output configuration information for the graph it supports. This output consists of a number of attributes. They are divided into one set of global attributes and then one or more set (s) of datasource-specific

attributes.

MUNIN-NODE — MUNIN 2.999.10-DETACHED-2018-12-16-C13 munin-node is a daemon for reporting statistics on system performance. By default, it is started at boot time, listens on port 4949/TCP, accepts connections from RECOMMENDED GRAPH_ARGS Units¶. See Best Current Practices for good plugin graphs--base ¶.

As of Munin 1.2 there is a generic interface for sending warnings and errors from Munin. If a Munin plugin discovers that a plugin has a data source breaching its defined limits, Munin is able to alert the administrator either through simple command line invocations or through a monitoring system like Nagios or

Icinga.

WHAT IS MUNIN?¶

Munin is a networked resource monitoring tool that can help analyze resource trends and "what just happened to kill our performance?" problems. It is designed to be very plug and play. A default installation provides a lot of graphs with almost no work. In Norse mythology Hugin and Munin are the ravens of the god king Odin. They flew all over Midgard for him, seeing and remembering, and later telling him. "Munin" means "memory". __ Check the demo server MONITORING WITHIN EASY REACH¶ Complicated does not mean efficient ; easy isn't superficial.

HOW DOES IT WORK?¶

Munin the monitoring tool surveys all your computers and remembers what it saw. It presents all the information in graphs through a web interface. Its emphasis is on plug and play capabilities. After completing an installation, a high number of monitoring plugins will be playing with no more effort. Using Munin you can easily monitor the performance of your computers, networks, SANs, applications, weather measurements and whatever comes to mind. It makes it easy to determine "what's different today" when a performance problem crops up. It makes it easy to see how you're doing capacity-wise on any resources. Munin uses the excellent ​RRDTool (written by Tobi Oetiker) and the framework is written in Perl, while plugins may be written in any language. Munin has a master/node architecture in which the master connects to all the nodes at regular intervals and asks them for data. It then stores the data in RRD files, and (if needed) updates the graphs. One of the main goals has been ease of creating new plugins (graphs).

PLUGINS¶

Plugins are small, standalone executables. They are easy to write, and can be written in any language. You can find many user contributed plugins in ​the contrib repository or easily

write your own ones
