CPU Usage statistics Dump in a text file over a period of time
I am facing issue related to performance of one customized application running on RHEL 5.9. The application stalls for some unknown reason that I need to track. For that I require some tool or shell scripts that can monitor the CPU usage statistics (what we get in TOP or in more detail by other means) with timestamp (may be 1 second periodically) into a plain .txt(ASCII file) file.I require to dump the statistics over a period of 1 hour. Can anybody help me out in this regard?
The above is my idea.But if some one is having other means to capture the process statistics over period of one hour, please share the same too.

xstat_cm_test
XSTAT_CM_TEST(1) AFS Command Reference XSTAT_CM_TEST(1)
NAME
xstat_cm_test - Displays data collections from the Cache Manager
SYNOPSIS
xstat_cm_test [initcmd]
-cmname <cache manager name(s) to monitor>+
-collID <collection(s) to fetch>+ [-onceonly]
[-frequency <poll frequency, in seconds>]
[-period <data collection time, in minutes>] [-debug]
[-help]
xstat_cm_test [i] -cm <cache manager name(s) to monitor>+
-co <collection(s) to fetch>+ [-o]
[-f <poll frequency, in seconds>]
[-p <data collection time, in minutes>] [-d] [-h]
DESCRIPTION
The xstat_cm_test command tests the routines in the libxstat_cm.a library and displays the data collections associated with the Cache
Manager. 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.
-cmname <cache manager name to monitor>+
Specifies the fully qualified hostname of each client machine for which to monitor the Cache Manager.
-collID <collection to fetch>+
Specifies each data collection to return, which defines the type and amount of data the command interpreter gathers about the Cache
Manager. Data is returned in a predefined data structure.
There are three acceptable values:
0 Provides profiling information about the numbers of times different internal Cache Manager routines were called since the Cache
Manager started.
1 Reports various internal performance statistics related to the Cache Manager (for example, statistics about how effectively the
cache is being used and the quantity of intracell and intercell data access).
2 Reports all of the internal performance statistics provided by the 1 setting, plus some additional, detailed performance figures
(for example, statistics about the number of RPCs sent by the Cache Manager and how long they take to complete, and statistics
regarding authentication, access, and PAG information associated with data access).
-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.
