I was contacted by a client last week regarding a monitoring server they have deployed. One of the applications they have gathering data from this server is Cacti. Anyhow they were able to login to Cacti but the graphs were not displaying. After logging into the server, which is running CentOS Linux, I saw the error clearly in the Litespeed logs. Below I describe the error in more detail as well as how to resolve this problem if you run into it.
Error Displaying Cacti Graphs Via Litespeed stderr.log In /var/lsws/logs:

You should initially look to make sure rrdtool is installed. In this case rrdtool had been removed for some reason so simply reinstalling rrdtool using the Yum Package Manager as shown in the example output below resolved the issue. If you want to first see if rrdtool is installed then use “locate rrdtool” but if it is not found then use the command below to install rrdtool.
Install rrdtool On CentOS Linux:

Once rrdtool was installed the cacti graphs started displaying without further issue.
