| 25 | =head1 DESCRIPTION | |
| 26 | ||
| 27 | The B<xstat_cm_test> command tests the routines in the F<libxstat_cm.a> | |
| 28 | library and displays the data collections associated with the Cache | |
| 29 | Manager. The command executes in the foreground. | |
| 30 | ||
| 31 | The command produces a large volume of output; to save it for later | |
| 32 | analysis, direct it to a file. | |
| 33 | ||
| 34 | =head1 OPTIONS | |
| 35 | ||
| 36 | =over 4 | |
| 37 | ||
| 38 | =item I<initcmd> | |
| 39 | ||
| 40 | Accommodates the command's use of the AFS command parser, and is optional. | |
| 41 | ||
| 42 | =item B<-cmname> <I<cache manager name to monitor>>+ | |
| 43 | ||
| 44 | Specifies the fully qualified hostname of each client machine for which to | |
| 45 | monitor the Cache Manager. | |
| 46 | ||
| 47 | =item B<-collID> <I<collection to fetch>>+ | |
| 48 | ||
| 49 | Specifies each data collection to return, which defines the type and | |
| 50 | amount of data the command interpreter gathers about the Cache Manager. | |
| 51 | Data is returned in a predefined data structure. | |
| 52 | ||
| 53 | There are three acceptable values: | |
| 54 | ||
| 55 | =over 4 | |
| 56 | ||
| 57 | =item C<0> | |
| 58 | ||
| 59 | Provides profiling information about the numbers of times different | |
| 60 | internal Cache Manager routines were called since the Cache Manager | |
| 61 | started. | |
| 62 | ||
| 63 | =item C<1> | |
| 64 | ||
| 65 | Reports various internal performance statistics related to the Cache | |
| 66 | Manager (for example, statistics about how effectively the cache is being | |
| 67 | used and the quantity of intracell and intercell data access). | |
| 68 | ||
| 69 | =item C<2> | |
| 70 | ||
| 71 | Reports all of the internal performance statistics provided by the C<1> | |
| 72 | setting, plus some additional, detailed performance figures (for example, | |
| 73 | statistics about the number of RPCs sent by the Cache Manager and how long | |
| 74 | they take to complete, and statistics regarding authentication, access, | |
| 75 | and PAG information associated with data access). | |
| 76 | ||
| 77 | =back | |
| 78 | ||
| 79 | =item B<-onceonly> | |
| 80 | ||
| 81 | Gathers statistics just one time. Omit this flag to have the command | |
| 82 | continue to probe the Cache Manager for statistics at the frequency | |
| 83 | specified by the B<-frequency> argument; in this case press Ctrl-C to stop | |
| 84 | the probes. | |
| 85 | ||
| 86 | =item B<-frequency> <I<poll frequency>> | |
| 87 | ||
| 88 | Sets the frequency in seconds at which the program initiates probes to the | |
| 89 | Cache Manager. The default is 30 seconds. | |
| 90 | ||
| 91 | =item B<-period> <I<data collection time>> | |
| 92 | ||
| 93 | Sets the number of minutes the program runs; at the end of this period of | |
| 94 | time, the program exits. The default is 10 minutes. | |
| 95 | ||
| 96 | =item B<-debug> | |
| 97 | ||
| 98 | Displays a trace on the standard output stream as the command runs. | |
| 99 | ||
| 100 | =item B<-help> | |
| 101 | ||
| 102 | Prints the online help for this command. All other valid options are | |
| 103 | ignored. | |
| 104 | ||
| 105 | =item B<-version> | |
| 106 | ||
| 107 | Prints the program version and then exits. All other valid options | |
| 108 | are ignored. | |
