2. page out
3. fre
They are all collected by "vmstat" command.
I want to know, except for above... (2 Replies)

Hi,
I would like to hear your thoughts about this. We are running our Data warehouse on DB2 DPF (partition environment) and I have notice that sometimes we hit the Asynchronous-I/O-Processes peak. DB2 relies heavily on Asynchronous I/O so I would believe this has an negative impact.We are... (10 Replies)

pmdarsyslog
PMDARSYSLOG(1) Performance Co-Pilot PMDARSYSLOG(1)NAME
pmdarsyslog - rsyslog (reliable and extended syslog) PMDA
DESCRIPTION
pmdarsyslog is a Performance Metrics Domain Agent (PMDA) which exports metric values from the rsyslogd(8) server. Further details about
rsyslog can be found at http://www.rsyslog.com/.
INSTALLATION
If you want access to the names and values for the rsyslog performance metrics, do the following as root:
# cd $PCP_PMDAS_DIR/rsyslog
# ./Install
If you want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/rsyslog
# ./Remove
pmdarsyslog 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.
In order to use this agent, rsyslog stats gathering must be enabled. This is done by adding the lines:
$ModLoad impstats
$PStatsInterval 5 # log every 5 seconds
syslog.info |/var/log/pcp/rsyslog/stats
to your rsyslog.conf(5) configuration file after installing the PMDA. Take care to ensure the syslog.info messages do not get logged in
any other file, as this could unexpectedly fill your filesystem. Syntax useful for this is syslog.!=info for explicitly excluding these.
FILES
/var/log/pcp/rsyslog/stats
named pipe containing statistics exported from rsyslog, usually created by the PMDA Install script.
$PCP_PMDAS_DIR/rsyslog/Install
installation script for the pmdarsyslog agent
$PCP_PMDAS_DIR/rsyslog/Remove
undo installation script for the pmdarsyslog agent
$PCP_LOG_DIR/pmcd/rsyslog.log
default log file for error messages from pmdarsyslog
