SYNOPSIS

-collID <collection(s) to fetch>+ [-onceonly]
[-frequency <poll frequency, in seconds>]
[-period <data collection time, in minutes>] [-debug] [-help]

xstat_fs_test [initcmd] -fs <File Server name(s) to monitor>+
-c <Collection(s) to fetch>+ [-o]
[-fr <poll frequency, in seconds>]
[-p <data collection time, in minutes>] [-d] [-h]

DESCRIPTION


The xstat_fs_test command tests the routines in the libxstat_fs.a library and displays the
data collections associated with the File Server (the "fs" process). The command executes
in the foreground.

The command produces a large volume of output; to save it for later analysis, direct it to
a file.

OPTIONS


initcmd
Accommodates the command's use of the AFS command parser, and is optional.

-fsname <file server name to monitor>+
Specifies the fully qualified hostname of each file server machine for which to
monitor the File Server process.

-collID <collection to fetch>+
Specifies each data collection to return, which defines the type and amount of data
the command interpreter gathers about the File Server. Data is returned in a
predefined data structure.

There are four acceptable values:

0 Provides profiling information about the numbers of times different internal File
Server routines were called since the File Server started. This value is not
currently implemented; it returns no data.

1 Reports various internal performance statistics related to the File Server (for
example, vnode cache entries and Rx protocol activity).

2 Reports all of the internal performance statistics provided by the 1 setting, plus
some additional, detailed performance figures about the File Server (for example,
minimum, maximum, and cumulative statistics regarding File Server RPCs, how long
they take to complete, and how many succeed).

3 Reports File Server callback processing statistics since the File Server started,
including the number of call of callbacks added (AddCallBack), the number of
callbacks broken (BreakCallBacks), and the number of callback space reclaims
(GetSomeSpaces).

-onceonly
Gathers statistics just one time. Omit this flag to have the command continue to probe
the Cache Manager for statistics at the frequency specified by the -frequency
argument; in this case press Ctrl-C to stop the probes.

-frequency <poll frequency>
Sets the frequency in seconds at which the program initiates probes to the Cache
Manager. The default is 30 seconds.

-period <data collection time>
Sets the number of minutes the program runs; at the end of this period of time, the
program exits. The default is 10 minutes.

-debug
Displays a trace on the standard output stream as the command runs.

-help
Prints the online help for this command. All other valid options are ignored.
