5.5.6.3 Installing and configuring colplot for plotting collectl data

IMPORTANT: Do not to use this option for HP Insight CMU diskless configurations.

1.On the HP Insight CMU administration server, create an NFS export a directory to store collectl data from compute nodes:

#mkdir /var/log/collectl

#vi /etc/exports

2.Add the following line:

/var/log/collectl *(rw,sync,no_all_squash,no_root_squash)

3.Refresh exports:

#exportfs -r

4.Install the collectl-utilspackage from the HP Insight CMU CDROM in tools/ collectl:

NOTE: In order to install collectl-utilsyou must install the gnuplot rpm.

#mount /dev/cdrom /mnt

#cd /mnt/tools/collectl

#rpm -ivh collectl-utils-x.x-x.noarch.rpm

creating

creating

/var/www/html/colplot

5.Copy colplot HTML files to the HP Insight CMU web directory. Those files are located in different directories depending on whether your HP Insight CMU administration server runs a Red Hat or SUSE distribution.

•For Red Hat:

#cp -a /var/www/html/colplot /opt/cmu/www/colplot

•For SUSE:

#cp -a /srv/www/htdocs/colplot /opt/cmu/www/colplot

6.Change the default colplot plot directory to point to the common collectl directory:

# vi /etc/colplot.conf

#PlotDir = /opt/hp/collectl/plotfiles PlotDir = /var/log/collectl

7.If not already done, install the collectl rpm on compute nodes:

# mount /dev/cdrom /mnt

# cd /mnt/tools/collectl

#rpm -ivh collectl-3.x.x-x.noarch.rpm

8.Otherwise, if the collectl rpm is already installed, ensure that collectl is stopped:

# /etc/init.d/collectl stop
