Example: WorkDir: /usr/tardis/pub/www/stats/mrtg _________________________________________________________________ Optional Global Parameters _________________________________________________________________ Refresh How many seconds apart should the browser (Netscape) be instructed to reload the page? If this is not defined, the default is 300 seconds (5 minutes). Example: Refresh: 600 _________________________________________________________________ Interval How often do you call mrtg? The default is 5 minutes. If you call it less often, you should specify it here. This does two things: * the generated HTML page does contain the right information about the calling interval ... * a META header in the generated HTML page will instruct caches about the time to live of this page ..... In this example we tell mrtg that we will be calling it every 10 minutes. If you are calling mrtg every 5 minutes, you can leave this line commented out. Example: Interval: 10 _________________________________________________________________ WriteExpires With this switch mrtg will generate .meta files for CERN and Apache servers which contain Expiration tags for the html and gif files. The *.meta files will be created in the same directory as the other files, so you will have to set ``MetaDir .'' and ``MetaFiles on'' in your apache.conf or .htaccess file for this to work NOTE: If you are running Apache-1.2 or later, you can use the mod_expire to achieve the same effect ... see the file htaccess.txt Example: WriteExpires: Yes _________________________________________________________________ IconDir If you want to keep the mrtg icons in some place other than the working directory, use the IconDir variable to give its url. Example: IconDir: /mrtgicons/ _________________________________________________________________ LoadMIBs Load the MIB file(s) specified and make its OIDs available as symbolic names. For better efficiancy, a cache of MIBs is maintained in the WorkDir. Example: LoadMIBs: /dept/net/mibs/netapp.mib,/usr/local/lib/ft100m.mib _________________________________________________________________ Language Switch output format to the selected Language (At the moment, the values: danish, french, english, dutch, brazilian, russian, spanish, greek and italian are supported) Example: Language: danish _________________________________________________________________ UseRRDTool Setting UseRRDTool to Yes in your mrtg.cfg file enables rrdtool mode. In rrdtool mode, mrtg relies on rrdtool to do its logging. Graphs and html pages will be generated on the fly by the 14all.cgi which can be found in the contrib section together with a short readme ... This feature has been contributed by [54]Rainer.Bawidamann@informatik.uni-ulm.de. Please check his website for more information: [55]http://www.uni-ulm.de/~rbawidam/mrtg-rrd/ Example: UseRRDTool: Yes _________________________________________________________________ RunAsDaemon The RunAsDaemon keyword enables daemon mode operation. The purpose of daemon mode is that MRTG is launched once and not at regular basis by cron as in native mode. This behavior saves computing resourses as loading and parsing of configuration files only hapens once. Using daemon mode MRTG itself is responible for timing the measurement intervals. Therfore its important to set the Interval keyword to an apropiate value. Note that using daemon mode MRTG should no longer be started from cron by regular basis as each started process runs forever. Instead MRTG should be started from the command prompt or by a system startup script. Also note that in daemon mode restart of the process is required in order to activate changes in the config file. Under UNIX, the Daemon switch causes mrtg to fork into background after checking its config file. Example RunAsDaemon:Yes Interval:5 Makes MRTG run as a daemon beginning data collection every 5 minutes _________________________________________________________________ Configuration for each Target you want to monitor The configuration keywords Target must be followed by a unique name. This will also be the name used for the webpages, logfiles and gifs created for that target. Note that the Target sections can be auto-generated with the cfgmaker tool. Check readme.html for instructions. _________________________________________________________________ Target With the Target keyword you tell mrtg what it should monitor. The Target keyword takes arguments in a wide range of formats: * The most basic format is ``port:community@router'' This will generate a traffic graph for the interface 'port' of the host 'router' (dns name or IP address) and it will use the community 'community' (snmp password) for the snmp query. Example: Target[ezwf]: 2:public@wellfleet-fddi.ethz.ch * Sometimes you are sitting on the wrong side of the link, and you would like to have mrtg report Incoming traffic as outgoing and
