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
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
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 IBM AFS
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
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.
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 IBM AFS Administration Guide.
