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-utils package from the HP Insight CMU CDROM in tools/
collectl

:

NOTE:

In order to install collectl-utils you must install the gnuplot rpm.

# mount /dev/cdrom /mnt

# cd /mnt/tools/collectl

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

apache found, enabling it to run colplot...
creating /etc/httpd/conf.d/colplot.conf
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

Preparing... ########################################### [100%]
1:collectl ########################################### [100%]

8.

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

# /etc/init.d/collectl stop
