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 client
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.
