Q What architectures are supported What operating systems Munin is programmed in Perl, which can be installed on most operating systems. In addition, it needs some perl modules, which you can fetch from CPAN. However, the plugins used by the client are often OS or application specific. E. g., many of the Linux plugins use proc to gather the data. There are some plugins that should work on most architectures. The architectures which have their own plugins as well, are. OS X Darwin supported in trunk. It is quite easy to make plugins for new OSes and were happy to accept contributions. If you portcreateimprove plugins, please contribute them to the project Q What is required to install munin More or less this. A reasonable Perl. I am trying to focus more on the windows version of JNOS 2. I have moved the JNOS WIN32 development to Windows. RRD with perl support. Perl modules for server Time Hi. Res, Storable, Digest MD5, HTML Template, Text Balanced. Perl modules for node Net Server. Perl modules for plugins Depends on the plugins you want to use, but probably none. Please see the INSTALL file for complete and updated requirements. Q My munin node stops every day at midnight on Free. Installing Mrtg Windows' title='Installing Mrtg Windows' />Many disk utilties including Equalise and ShowMan.

Surprisingly considering that it negotiates a secure connection nothing special either. You do not need persistent portclient connection for this. Advanced Tutorials. These tutorials require a certain degree of knowledge about general networking that some new users may or may not understand. BSD. The last message in munin node. Insecure dependency in exec while running with T switch. This is a bug in recent versions of the Perl module Net Server, see http rt. PublicBugDisplay. Apply the mentioned patch to Server. Q munin node doesnt start and varlogmuninmunin. Couldnt chown varrunmuninmunin node. This problem occurs when you try to run munin node as the munin user. Run munin node as root instead. Note that the munin master should run as munin, but munin node as root. Configuration. A guide to server configuration is in the wiki page munin. Some interesting things that are not covered in that page is shown in this FAQ. Q What should a minimal server configuration look like The server will query the node and show all the servicesplugins it offers. Q Can I set or override the critical and warning levels, or other parameters, for a plugin Of course you can. Everything you define in munin. Example On the host foo. I want to set the df plugins warning level for the home mount point to 9. Then, your munin. This also applies to almost all other parameters in the plugins, even if overriding those might not make much sense. The syntax in the entry is pluginname. On the Munin page for the individual plugin, the fieldnames are listed as Internal name below the graphs. Note. Plugin override is very different of plugin configuration. We can resume by that plugin configuration is done when plugin cooperates and plugin override is done otherwise. Here is a table with the main differences. Plugin Configuration Plugin Override. Directly editing the plugin to change some config is really discouraged, better enhance the plugin for it to support plugin configuration and submit it upstream. This will save you lots of work on future maintenance when you will upgrade the plugins packages. Q How do I use the fieldname. The cdef is fed to rrdtool graph so the man page for rrdgraph should give you a bit more info. Ill try to explain it briefly here, though. The cdef is defined using Reverse Polish Notation RPN, which means that you would say 4,5, instead of 45. When you create a cdef field, be sure to use the fieldname at least once in the definition, or rrdgraph will croak with an error. For a more thorough definition of RPN, take a look at the man page for rrdgraph. Q Can I make a graph show values per minute instead of per second In your munin. See graphperiod for details. Q Can I get a graph to show percentages instead of regular values You can modify a graph with two data fields to a percentage view with the following cdef gotten from Nicolai Langfeldt. It uses two field names, hit and all with hit being the field you want in percentages of all. EQ,IF,1. 00,UNKN,all,0,EQ,IF,UNKN,all,UNKN,EQ,IF. Q How do I define aliases Its the same as borrowing data from another graph that is answered just below. Q How do I borrow data from another graph See also Loaning. Data. Normally, graphorder looks something like this. It can, however, be used to define alises from other graphs. E. g. if you want to incorporate the number of http connections in the processes graph i. This would first draw the processes data source as normal, then draw the count data source from the porthttp graph. Example graphorders. Will draw two normal values. Will draw two normal values, the second an alias to the first. Loan a data source from another graph. Loan a data source from another hosts graph. Loan a data source from another domains graph. Q How do I use fieldname. The format of stack is the same as the graphorder arguments above. You cannot, however, specify extra arguments for the fields. Winrar 3 93 Final Br X86 Bit there.
