xstat_fs - Displays data collections from the File Server process
xstat_fs [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] [-format] [-help]
The xstat_fs command displays the data collections associated with the File Server (the
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.

Specifies the fully qualified hostname of each file server machine for which to monitor the File Server process.
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:
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.
Reports various internal performance statistics related to the File Server (for example, vnode cache entries and Rx protocol activity).
Reports all of the internal performance statistics provided by the
plus some additional,
detailed performance figures about the File Server (for example,
and cumulative statistics regarding File Server RPCs,
how long they take to complete,
and how many succeed).
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). This collection set is only available on OpenAFS File Servers. It is not supported by AuriStorFS File Servers.
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.
Sets the frequency in seconds at which the program initiates probes to the Cache Manager. The default is 30 seconds.
Sets the number of minutes the program runs; at the end of this period of time, the program exits. The default is 10 minutes.
