ubuntu 12.04 : install collectd

just referred to http://gabenell.blogspot.jp/2010/06/setting-up-collectd-collection3-on.html.

many thanks.

# tail -1 /etc/lsb-release DISTRIB_DESCRIPTION="Ubuntu 12.04.2 LTS" # uname -ri 3.2.0-39-generic x86_64

install collectd and packages which are required for collectd.

# apt-get install -y apache2 libconfig-general-perl librrds-perl libregexp-common-perl  libhtml-parser-perl collectd-core

configure collectd.

get CPU , memory , locad , memory , disk info.

# cat /etc/collectd/collectd.conf LoadPlugin cpu LoadPlugin load LoadPlugin memory LoadPlugin disk LoadPlugin rrdtool <Plugin rrdtool>  DataDir "/var/lib/collectd/rrd/" </Plugin>

start collectd

# service collectd restart

configure apache2 to check graphs via HTTP.

In my case , I configured TCP 8888 port as the collectd’s HTTP port.

# pwd /etc/apache2/sites-available # cat collectd <VirtualHost *:8888> ScriptAlias /collectd/bin/ /usr/share/doc/collectd-core/examples/collection3/bin/ Alias /collectd/ /usr/share/doc/collectd-core/examples/collection3/ <Directory /usr/share/doc/collectd-core/examples/collection3/>    AddHandler cgi-script .cgi    DirectoryIndex bin/index.cgi    Options +ExecCGI    Order Allow,Deny    Allow from all </Directory> </VirtualHost>

edit ports.conf to listen on TCP 8888.

# egrep -v ^# /etc/apache2/ports.conf NameVirtualHost *:8888 Listen 8888 <IfModule mod_ssl.c>    # If you add NameVirtualHost *:443 here, you will also have to change    # the VirtualHost statement in /etc/apache2/sites-available/default-ssl    # to <VirtualHost *:443>    # Server Name Indication for SSL named virtual hosts is currently not    # supported by MSIE on Windows XP.    Listen 443 </IfModule> <IfModule mod_gnutls.c>    Listen 443 </IfModule>

enable collectd site and start apache2.

# a2ensite collectd # service apache2 restart

access to http://<collectd’s IP>:8888/collectd

CPU usage

Memory usage

add other graphs

There are plugins under /var/lib/collectd directory.

# pwd /usr/lib/collectd # ls | head -10 apache.so apcups.so ascent.so battery.so bind.so conntrack.so contextswitch.so cpu.so cpufreq.so csv.so

edit collection.conf ( add TCP connections )

# cat /etc/collectd/collectd.conf LoadPlugin cpu LoadPlugin load LoadPlugin memory LoadPlugin disk LoadPlugin rrdtool LoadPlugin tcpconns <Plugin rrdtool>  DataDir "/var/lib/collectd/rrd/" </Plugin>

restart collectd

# /etc/init.d/collectd restart
