We are using SNMP and MRTG to monitor our squid-cache proxy. Find example we used. You should modified it for your case. kkadow@xxxxxxxxx@inet 30.03.2005 04:46 Please respond to kkadow@xxxxxxxxx@inet To squid-users@xxxxxxxxxxxxxxx cc rmorris@xxxxxxxx Subject Re: [squid-users] Measuring Squid Efficiency On Tue, 29 Mar 2005 20:52:29 -0500, Bob Morrison <rmorris@xxxxxxxx> wrote: > I am new to squid and would like to know what information > to look for to see if a squid cache needs adjusting to > perform more efficiently. There're a number of reporting scripts out there which will parse your access.log and report cache hit rates, which will provide hard statistics on cache *effectiveness*. For a list, see: http://www.squid-cache.org/Scripts/ These are useful for showing management the hard and soft dollar savings from deploying web caching. By efficiency, I assume you are looking for a way to learn whether your current settings for "replacement policy" and for "refresh_pattern" are efficient, or whether objects are being re-fetched when, under a different tuning, they could potentially have been served out of cache? Or perhaps you mean something else by "efficiency"? Thanks, Kevin

If this is not defined, the # default is 300 seconds (5 minutes). # Refresh: 600 # 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: # a) the generated HTML page does contain the right # information about the calling interval ... # b) 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.

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 port 'port' # of the router 'router' and it will use the community # 'community' for the snmp query. # Target[ezwf]: 2:public@xxxxxxxxxxxxxxxxxxxxxx # * Sometimes you are sitting on the wrong side of the # link. And you would like to have mrtg report Incoming # traffic as outgoing and visa versa. This can be achieved # by adding the '-' sign in front of the "Target" # description. It flips the in and outgoing traffic rates. # Target[ezci]: -1:public@xxxxxxxxxxxxxxxxxx # * You can also explicitly define the OID to query by using the # following syntax 'OID_1&OID_2:community@router' # The following example will retrieve error input and output # octets/sec on interface 1. MRTG needs to graph two values, so # you need to specify two OID's such as temperature and humidity # or error input and error output. # Target[ezwf]: 1.3.6.1.2.1.2.2.1.14.1&1.3.6.1.2.1.2.2.1.20.1:public@myrouter # * mrtg knows a number of symbolical SNMP variable # names. See the file mibhelp.txt for a list of known # names. One example are the ifInErrors and and ifOutErrors # names. This means you can specify the above as: # Target[ezwf]: ifInErrors.1&ifOutErrors.1:public@myrouter # * if you want to monitor something which does not provide # data via snmp you can use some external program to do # the data gathering. # # The external command must return 4 lines of output: # Line 1 : current state of the 'incoming bytes counter' # Line 2 : current state of the 'outgoing bytes counter' # Line 3 : string, telling the uptime of the target. # Line 4 : string, telling the name of the target. # Depending on the type of data your script returns you # might want to use the 'gauge' or 'absolute' arguments # for the "Options" keyword. # Target[ezwf]: `/usr/local/bin/df2mrtg /dev/dsk/c0t2d0s0` # * You can also use several statements in a mathematical # expression. This could be used to aggregate both B channels # in an ISDN connection or multiple T1's that are aggregated # into a single channel for greater bandwidth. # Note the whitespace arround the target definitions. # Target[ezwf]: 2:public@wellfleetA + 1:public@wellfleetA # * 4:public@ciscoF ## ## RouterUptime --------------------------------------- ## # # In cases where you calculate the used bandwidth from # several interfaces you normaly don't get the routeruptime # and routername displayed on the web page. # If this interface are on the same router and the uptime and # name should be displayed nevertheless you have to specify # its community and address again with the RouterUptime keyword. # Target[kacisco]: 1:public@xxxxxxxxxxxxx + 2:public@xxxxxxxxxxxxx # RouterUptime[kacisco]: public@xxxxxxxxxxxxx ## ## MaxBytes ------------------------------------------- ## # How many bytes per second can this port carry. Since most # links are rated in bits per second, you need to divide # their maximum bandwidth (in bits) by eight (8) in order to get # bytes per second. This is very important to make your # unscaled graphs display realistic information. # T1 = 193000, 56K = 7000, Ethernet = 1250000. The "MaxBytes" # value will be used by mrtg to decide whether it got a # valid response from the router. If a number higher than # "MaxBytes" is returned, it is ignored. Also read the section # on AbsMax for further info. # MaxBytes[ezwf]: 1250000 ## ## Title ----------------------------------------------- ## # Title for the HTML page which gets generated for the graph. # Title[ezwf]: Traffic Analysis for ETZ C 95.1 ## ## PageTop --------------------------------------------- ## # Things to add to the top of the generated HTML page. Note # that you can have several lines of text as long as the # first column is empty. # Note that the continuation lines will all end up on the same # line in the html page. If you want linebreaks in the generated # html use the '\n' sequence. # PageTop[ezwf]: <H1>Traffic Analysis for ETZ C95.1</H1> # Our Campus Backbone runs over an FDDI line\n # with a maximum transfer rate of 12.5 Mega Bytes per # Second. ## ## PageFoot --------------------------------------------- ## # Things to add at the very end of the mrtg generated html page # PageFoot[ezwf]: <HR size=2 noshade>This page is managed by Blubber # -------------------------------------------------- # Optional Target Configuration Tags # -------------------------------------------------- ## ## AddHead ----------------------------------------- ## # Use this tag like the PageTop header, but its contents # will be added between </TITLE> and </HEAD>. # AddHead[ezwf]: <!-- Just a comment for fun --> ## ## AbsMax ------------------------------------------ ## # If you are monitoring a link which can handle more traffic # than the MaxBytes value. Eg, a line which uses compression # or some frame relay link, you can use the AbsMax keyword # to give the absolute maximum value ever to be reached. We # need to know this in order to sort out unrealistic values # returned by the routers. If you do not set absmax, rateup # will ignore values higher then MaxBytes. # AbsMax[ezwf]: 2500000 ## ## Unscaled ------------------------------------------ ## # By default each graph is scaled vertically to make the # actual data visible even when it is much lower than # MaxBytes. With the "Unscaled" variable you can suppress # this. It's argument is a string, containing one letter # for each graph you don't want to be scaled: d=day w=week # m=month y=year. In the example I suppress scaling for the # yearly and the monthly graph. # Unscaled[ezwf]: ym ## ## WithPeak ------------------------------------------ ## # By default the graphs only contain the average transfer # rates for incoming and outgoing traffic. The # following option instructs mrtg to display the peak # 5 minute transfer rates in the [w]eekly, [m]onthly and # [y]early graph. In the example we define the monthly # and the yearly graph to contain peak as well as average # values. # WithPeak[ezwf]: ym ## ## Supress ------------------------------------------ ## # By Default mrtg produces 4 graphs. With this option you # can suppress the generation of selected graphs. The format # is analog to the above option. In this example we suppress # the yearly graph as it is quite empty in the beginning. # Suppress[ezwf]: y ## ## Directory ## # By default, mrtg puts all the files that it generates for each # router (the GIFs, the HTML page, the log file, etc.) in WorkDir. # If the "Directory" option is specified, the files are instead put # into a directory under WorkDir. (For example, given the options in # this mrtg.cfg-dist file, the "Directory" option below would cause all # the ezwf files to be put into /usr/tardis/pub/www/stats/mrtg/ezwf .) # # The directory must already exist; mrtg will not create it. # Directory[ezwf]: ezwf ## ## XSize and YSize ------------------------------------------ ## # By Default mrtgs graphs are 100 by 400 pixels wide (plus # some more for the labels. In the example we get almost # square graphs ... # Note: XSize must be between 20 and 600 # YSize must be larger than 20 # XSize[ezwf]: 300 # YSize[ezwf]: 300 ## ## XZoom YZoom ------------------------------------------------- ## # If you want your graphs to have larger pixels, you can # "Zoom" them. #XZoom[ezwf]: 2.0 #YZoom[ezwf]: 2.0 ## ## XScale YScale ------------------------------------------------- ## # If you want your graphs to be actually scaled use XScale # and YScale. (Beware while this works, the results look ugly # (to be frank) so if someone wants fix this: patches are # welcome. # XScale[ezwf]: 1.5 # YScale[ezwf]: 1.5 ## ## Step ----------------------------------------------------------- ## # Change the default step with from 5 * 60 seconds to # something else I have not tested this well ... # Step[ezwf]: 60 ## ## Options ------------------------------------------ ## # The "Options" Keyword allows you to set some boolean # switches: # # growright - The graph grows to the left by default. # # bits - All the numbers printed are in bits instead # of bytes ... looks much more impressive :-) # # noinfo - Supress the information about uptime and # device name in the generated webpage. # # absolute - This is for data sources which reset their # value when they are read. This means that # rateup has not to build the difference between # this and the last value read from the data # source. Useful for external data gatherers. # # gauge - Treat the values gathered from target as absolute # and not as counters. This would be useful to # monitor things like diskspace, load and so # on .... # # nopercent Don't print usage percentages # # integer Don't print only integers in the summary ... # # Options[ezwf]: growright, bits ## ## Colours ------------------------------------------ ## # The "Colours" tag allows you to override the default colour # scheme. Note: All 4 of the required colours must be # specified here The colour name ('Colourx' below) is the # legend name displayed, while the RGB value is the real # colour used for the display, both on the graph and n the # html doc. # Format is: Colour1#RRGGBB,Colour2#RRGGBB,Colour3#RRGGBB,Colour4#RRGGBB # where: Colour1 = Input on default graph # Colour2 = Output on default graph # Colour3 = Max input # Colour4 = Max output # RRGGBB = 2 digit hex values for Red, Green and Blue # Colours[ezwf]: GREEN#00eb0c,BLUE#1000ff,DARK GREEN#006600,VIOLET#ff00ff ## ## Background ------------------------------------------ ## # With the "Background" tag you can configure the background # colour of the generated HTML page # Background[ezwf]: #a0a0a0a ## ## YLegend, ShortLegend, Legend[1234] ------------------ ## # The following keywords allow you to override the text # displayed for the various legends of the graph and in the # HTML document # # * YLegend : The Y-Axis of the graph # * ShortLegend: The 'b/s' string used for Max, Average and Current # * Legend[1234IO]: The strings for the colour legend # #YLegend[ezwf]: Bits per Second #ShortLegend[ezwf]: b/s #Legend1[ezwf]: Incoming Traffic in Bits per Second #Legend2[ezwf]: Outgoing Traffic in Bits per Second #Legend3[ezwf]: Maximal 5 Minute Incoming Traffic #Legend4[ezwf]: Maximal 5 Minute Outgoing Traffic #LegendI[ezwf]: In: #LegendO[ezwf]: Out: # Note, if LegendI or LegendO are set to an empty string with # LegendO[ezwf]: # The corresponding line below the graph will not be printed at all. # If you live in an international world, you might want to # generate the graphs in different timezones. This is set in the # TZ variable. Under certain operating systems like Solaris, # this will provoke the localtime call to giv the time in # the selected timezone ... # Timezone[ezwf]: Japan # The Timezone is the standard Solaris timezone, ie Japan, Hongkong, # GMT, GMT+1 etc etc. # By default, mrtg (actually rateup) uses the strftime(3) '%W' option # to format week numbers in the monthly graphs. The exact semantics # of this format option vary between systems. If you find that the # week numbers are wrong, and your system's strftime(3) routine # supports it, you can try another format option. The POSIX '%V' # option seems to correspond to a widely used week numbering # convention. The week format character should be specified as a # single letter; either W, V, or U. # Weekformat[ezwf]: V # ############################# # Two very special Target names # ############################# # To save yourself some typing you can define a target # called '^'.
