Change references to the documentation sets that we still ship to reference the OpenAFS manuals instead of the IBM AFS manuals. Remove references to the IBM AFS/DFS Migration documentation, since that doesn't appear to be available anywhere any more, replacing them where relevant to more generic references to the DFS documentation. Add links to docs.openafs.org for mentions of the manuals in SEE ALSO, and standardize on one link format. Replace a few references to the IBM AFS Release Notes with the actual information in those notes, or drop the reference if it doesn't seem particularly useful.

=head1 NAME

|
|
|
afsmonitor - Provides instructions for the afsmonitor command
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The afsmonitor configuration file determines which machines the
|
|
B<afsmonitor> command probes for File Server or Cache Manager statistics
|
|
and which statistics it gathers. Use the B<-config> argument to the
|
|
B<afsmonitor> command to identify the configuration file to use.
|
|
|
|
The instructions that can appear in the configuration file are as follows:
|
|
|
|
=over 4
|
|
|
|
=item cm <I<host name>>
|
|
|
|
Names a client machine for which to display Cache Manager statistics. The
|
|
order of C<cm> lines in the file determines the order in which client
|
|
machines appear from top to bottom on the C<System Overview> and C<Cache
|
|
Managers> output screens.
|
|
|
|
=item fs <I<host name>>
|
|
|
|
Names a file server machine for which to display File Server
|
|
statistics. The order of C<fs> lines in the file determines the order in
|
|
which file server machines appear from top to bottom on the C<System
|
|
Overview> and C<File Servers> output screens.
|
|
|
|
=item thresh (fs | cm) <I<field>> <I<thresh>> [<I<cmd>>] [<I<arg>> ...]
|
|
|
|
Assigns the threshold value I<thresh> to the statistic I<field>, for
|
|
either a File Server statistic (C<fs>) or a Cache Manager statistic
|
|
(C<cm>). The optional I<cmd> field names a binary or script to execute
|
|
each time the value of the statistic changes from being below I<thresh> to
|
|
being at or above I<thresh>. A change between two values that both exceed
|
|
I<thresh> does not retrigger the binary or script. The optional I<arg>
|
|
fields are additional values that the B<afsmonitor> program passes as
|
|
arguments to the I<cmd> command. If any of them include one or more
|
|
spaces, enclose the entire field in double quotes.
|
|
|
|
The B<afsmonitor> program passes the following parameters to the I<cmd>:
|
|
|
|
<hostname> (fs|cm) <field> <thresh> <actual> [<arg> ...]
|
|
|
|
The parameters C<fs>, C<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 C<thresh> line to set either a global threshold, which applies to
|
|
all file server machines listed on C<fs> lines or client machines listed
|
|
on C<cm> lines in the configuration file, or a machine-specific threshold,
|
|
which applies to only one file server or client machine.
|
|
|
|
=over 4
|
|
|
|
=item *
|
|
|
|
To set a global threshold, place the thresh line before any of the C<fs>
|
|
or C<cm> lines in the file.
|
|
|
|
=item *
|
|
|
|
To set a machine-specific threshold, place the thresh line below the
|
|
corresponding C<fs> or C<cm> line, and above any other C<fs> or C<cm>
|
|
lines. A machine-specific threshold value always overrides the
|
|
corresponding global threshold, if set. Do not place a C<thresh fs> line
|
|
directly after a C<cm> line or a C<thresh cm> line directly after a C<fs>
|
|
line.
|
|
|
|
=back
|
|
|
|
=item show (fs | cm) I<field/group/section>
|
|
|
|
Specifies which individual statistic, group of statistics, or section of
|
|
statistics to display on the C<File Servers> screen (C<fs>) or C<Cache
|
|
Managers> screen (C<cm>) and the order in which to display them. The
|
|
appendix of B<afsmonitor> statistics in the I<OpenAFS Administration
|
|
Guide> specifies the group and section to which each statistic
|
|
belongs. Include as many C<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 C<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 C<show> lines in the configuration file, then the screens
|
|
display all statistics for both Cache Managers and File
|
|
Servers. Similarly, if there are no C<show fs> lines, the C<File Servers>
|
|
screen displays all file server statistics, and if there are no C<show cm>
|
|
lines, the C<Cache Managers> screen displays all client statistics.
|
|
|
|
=item # I<comments>
|
|
|
|
Precedes a line of text that the afsmonitor program ignores because of the
|
|
initial number (C<#>) sign, which must appear in the very first column of
|
|
the line.
|
|
|
|
=back
|
|
|
|
For a list of the values that can appear in the I<field/group/section>
|
|
field of a C<show> instruction, see the B<afsmonitor> statistics appendix
|
|
to the I<OpenAFS Administration Guide>.
