xstat_fs_test - Displays data collections from the File Server
process
xstat_fs_test [initcmd]
-fsname <file server name(s) to monitor>+
-collID <collection(s) to fetch>+
[-onceonly]
[-frequency <poll frequency, in seconds>]
[-period <data collection time, in minutes>]
[-debug] [-version] [-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] [-version] [-h]
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.
- 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.
- -version
- Prints the program version and then exits. All other valid options are
ignored.
