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

hi,
can any one tell me, is there is any way i can check the performance of my solaris 8 os on an Ent 3500. Other than top to check for the top most processes, how to make the calculations with vmstat, iostat, mpstat and nfsstat. Or is there any other tools that i can use?
cheers. (3 Replies)

I need to concatenate about a thousand files (using a loop) on a UNIX server. Also, each file has a header row which is to be removed. Which of the following would give better performance?
tail+2 <filename> or sed '1,1d' <filename>
Or is there another, faster way?
Thanks,

I'm doing performance testing for one application which works on AIX.
But I don't know which performance parameters of memory need to be collected. Now, I just know very few:

2. page out
3. fre
They are all collected by "vmstat" command.
