       afsmonitor - Provides instructions for the afsmonitor command


       The afsmonitor configuration file determines which machines the afsmonitor command probes
       for File Server or Cache Manager statistics and which statistics it gathers. Use the
       -config argument to the afsmonitor command to identify the configuration file to use.

       The instructions that can appear in the configuration file are as follows:

       cm <host name>
           Names a client machine for which to display Cache Manager statistics. The order of
           "cm" lines in the file determines the order in which client machines appear from top
           to bottom on the "System Overview" and "Cache Managers" output screens.

       fs <host name>
           Names a file server machine for which to display File Server statistics. The order of
           "fs" lines in the file determines the order in which file server machines appear from
           top to bottom on the "System Overview" and "File Servers" output screens.

       thresh (fs | cm) <field> <thresh> [<cmd>] [<arg> ...]
           Assigns the threshold value thresh to the statistic field, for either a File Server
           statistic ("fs") or a Cache Manager statistic ("cm"). The optional cmd field names a
           binary or script to execute each time the value of the statistic changes from being
           below thresh to being at or above thresh. A change between two values that both exceed
           thresh does not retrigger the binary or script. The optional arg fields are additional
           values that the afsmonitor program passes as arguments to the cmd command. If any of
           them include one or more spaces, enclose the entire field in double quotes.

           The afsmonitor program passes the following parameters to the cmd:

               <hostname> (fs|cm) <field> <thresh> <actual> [<arg> ...]

           The parameters "fs", "cm", <field>, <thresh>, and <arg> correspond to the values with
           the same name on the thresh line. The <hostname> parameter identifies the file server
           or client machine where the statistic has crossed the threshold, and the <actual>
           parameter is the actual value of <field> that exceeds the threshold value.

           Use the "thresh" line to set either a global threshold, which applies to all file
           server machines listed on "fs" lines or client machines listed on "cm" lines in the
           configuration file, or a machine-specific threshold, which applies to only one file
           server or client machine.

           •   To set a global threshold, place the thresh line before any of the "fs" or "cm"
               lines in the file.

           •   To set a machine-specific threshold, place the thresh line below the corresponding
               "fs" or "cm" line, and above any other "fs" or "cm" lines. A machine-specific
               threshold value always overrides the corresponding global threshold, if set. Do
               not place a "thresh fs" line directly after a "cm" line or a "thresh cm" line
               directly after a "fs" line.

       show (fs | cm) field/group/section
           Specifies which individual statistic, group of statistics, or section of statistics to
           display on the "File Servers" screen ("fs") or "Cache Managers" screen ("cm") and the
           order in which to display them. The appendix of afsmonitor statistics in the OpenAFS
           Administration Guide specifies the group and section to which each statistic belongs.
           Include as many "show" lines as necessary to customize the screen display as desired,
           and place them anywhere in the file. The top-to-bottom order of the "show" lines in
           the configuration file determines the left-to-right order in which the statistics
           appear on the corresponding screen.

           If there are no "show" lines in the configuration file, then the screens display all
           statistics for both Cache Managers and File Servers. Similarly, if there are no "show
           fs" lines, the "File Servers" screen displays all file server statistics, and if there
           are no "show cm" lines, the "Cache Managers" screen displays all client statistics.

       # comments
           Precedes a line of text that the afsmonitor program ignores because of the initial
           number ("#") sign, which must appear in the very first column of the line.

           Print the OpenAFS command suite version and then exit.

       For a list of the values that can appear in the field/group/section field of a "show"
       instruction, see the afsmonitor statistics appendix to the OpenAFS Administration Guide.
