PRAT - Platform Run Analysis Tool
|
|
|
|
|
|
Overview
|
|
--------
|
|
|
|
The PRAT utility is a set of shell scripts designed to collect system activity
|
|
and performance data so that it can be made available to Calpont Customer Support.
|
|
Run under the supervision of Calpont support personnel, the utility will prompt the user
|
|
for the start and stop times of a period where the performance of an individual query or
|
|
the overall system is an issue. PRAT will collect data from each of the hosts in a
|
|
particular Calpont installation and puts it into a format that can easily be
|
|
transmitted to Calpont.
|
|
|
|
PRAT is installed with the Calpont InfiniDB application. Automated processes that collect system activity
|
|
(i.e. the "ps" command) are also installed with the Calpont InfiniDB application. Finally,the PRAT utility
|
|
relies upon the presence of the sysstat rpm package (see the Calpont InfiniDB Installation Guide).
|
|

|
Usage Instructions
|
|
------------------
|
|
|
|
To use the PRAT utility, the user must execute the main PRAT script from the Calpont
|
|
tools directory:
|
|
|
|
/usr/local/Calpont/tools/prat.sh
|
|
|
|
The user will then be prompted for the two digit day of the month of the time period in
|
|
question. The user will also be prompted for the start and end times of the time period
|
|
under study (in the format of "hh:mm").
|
|
|
|
Once the time frame data is provided, the user will then be asked for the root password for
|
|
each host in the Calpont installation.
|
|
|
|
The utility will then collect all the pertinent data necessary to provide an analysis of
|
|
the overall system state and performance for the query or time period in question. This
|
|
data is collected in the data directory under the tools directory in the form of tar files.
|
|
There is one tar file for each host in the installation and these files are then in turn
|
|
sent to Calpont support personnel for analysis.
