CPU utilization problem
Hi All,
I have a shell script which pulls the data from 72 different servers. We are running multiple instances of this script into infinite loop i.e we have divided the script into 9 instances and each instance caters to 8 different servers. This scripts ftps the files from the servers, gzips these files and place them into a directory.
Now my problem is i want to make sure that my system doesn't crash because of the mutiple instances.So could anyone please tell me what all i should monitor to check the system's performance?
Thanks in anticipation

pmdamemcache
PMDAMEMCACHE(1) Performance Co-Pilot PMDAMEMCACHE(1)
NAME
pmdamemcache - memcache performance metrics domain agent (PMDA)
DESCRIPTION
This PMDA extracts performance data from memcached, a distributed memory caching daemon commonly used to improve web serving performance.
A farm of memcached processes over multiple servers can be utilised by a single web application, increasing the total available object
cache size, and decreasing the database load associated with smaller cache sizes. This system is described in detail at
http://www.danga.com/memcached.
INSTALLATION
Configure pmdamemcache to extract the values from set of hosts used in the memcache farm. These hosts can be listed in the
$PCP_PMDAS_DIR/memcache/memcache.conf file, in the format (i.e. Perl array) described at the top of pmdamemcache.pl. A custom refresh
rate can also be configured using this mechanism.
# cd $PCP_PMDAS_DIR/memcache
# [ edit memcache.conf ]
Once this is setup, you can access the names and values for the memcache performance metrics by doing the following as root:
# cd $PCP_PMDAS_DIR/memcache
# ./Install
If you want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/memcache
# ./Remove
pmdamemcache is launched by pmcd(1) and should never be executed directly. The Install and Remove scripts notify pmcd(1) when the agent is
installed or removed.
FILES
$PCP_PMDAS_DIR/memcache/memcache.conf
configuration file listing monitored memcache instances
$PCP_PMDAS_DIR/memcache/Install
installation script for the pmdamemcache agent
$PCP_PMDAS_DIR/memcache/Remove
undo installation script for the pmdamemcache agent
$PCP_LOG_DIR/pmcd/memcache.log
default log file for error messages from pmdamemcache
