If you have received a notification of excessive server resource usage then this article will assist you understanding the logs we provide. The example below is for the fictional domain rochendemo.com with the username rochendemo.<\/p>\n

The first figure of 3.50 is the average % of CPU usage over a 24 hour period. This is generally the statistic which triggers an excessive resource usage ticket.\u00a0The second figure of 0.52 is the average % of Memory usage over a 24 hour period.\u00a0The third figure is not something which we use commonly. It represents the average number of established MySQL connections over a 24 hour period.<\/p>\n
Each set of daily statistics will give the top 3 single processes by CPU usage.\u00a0In the example the top single process uses 142% of the available CPU to execute and output. This typically means 100% of 1 CPU was utilized and 42% of a 2nd CPU. Generally well coded scripts or components will not peak above 35-40%. Any resource intensive script (something which should not be run in a shared environment) or extension\/plugin\/module\/addon will also cause a high spike.<\/p>\n
The top process in our example also lists the script which is being executed. In some cases this can be helpful to track down the problem however the top 3 single processes may not be the cause of the overall high average usage.\u00a0In many cases, like in the 2nd top process, only [php] will be shown.\u00a0This simply means the spike was from a PHP process under the account. Unfortunately cPanel does not log a great deal of detail. The reason for this is that extensive logging would result in a significant amount of load and thus be counterproductive to overall performance on the server.<\/p>\n","protected":false},"excerpt":{"rendered":"
