RRDTOOL - Graphs are missing or RRDTOOL not installed

THIS ARTICLE IS DEPRECATED! RRDTOOL NO LONGER APPLIES TO CLUSTERCONTROL.

This article describes how to resolve problems with graphs:

1. Verify that 'rrdtool' is installed by running from a terminal on the ClusterControl server:
   which rrdtool 
   Expected result:
   /usr/bin/rrdtool 
2. Check that you have a /etc/cmon_rrd.cnf file, and that it contains (please note that password, hostname, port, imagedir, may differ on your platform
   

   ##cmon rrd config file
   ##port of mysql server holding cmon database
   mysql_port=3306
   ##hostname/ip of mysql server holding cmon database
   mysql_hostname=10.176.131.76
   ##password for 'cmon' user on the 'mysql_hostname'
   mysql_password=cmon
   mysql_bindir=/usr/local//mysql/bin/
   ### imagedir for ubuntu/debian:
   imagedir=/var/www/cmon/graphs/
   ### imagedir for redhat/centos:
   #imagedir=/var/www/html/cmon/graphs/
   rrdtool=/usr/bin/rrdtool
   rrd_datadir=/var/lib/cmon/

3. Run in turn (the tools must be installed in /usr/bin/ ):
   /usr/bin/cmon_create_rrd
   /usr/bin/cmon_update_rrd
   /usr/bin/cmon_create_graphs 1d mini
   All three command should return without errors, if you can't determine what the error is, please file a Support request. 
4. Verify that you have cron running:
   

   ps -ef |grep cron
   Should print out something like:
   root 641 1 0 2012 ? 00:01:25 cron

    If not, install 'cron', google how to do this.
5. Verify you have /etc/cron.d/cmon  and it contains:
   

   #
   # cron-jobs for cmon
   #
   CMON_BINDIR=/usr/bin/
   MAILTO=root
