Monitoring Linux Disk and CPU Utilization
Rich Bryant | July 8, 2009
For many production Linux servers it is important (and perhaps critical) for managers and administrators to be kept up-to-date with regard to consumption of disk and CPU processing resources. Often being up to date with such information increases system up time and, more importantly, reduces the frequency of calls from affected users and customers.
Manually monitoring this information is costly and impractical, so it is also important that these monitoring processes be automated. Some commercial software is available to meet this need, however the features of the Linux operating system, coupled with the text processing power of the PERL language, allow for simple and effective system monitoring scripts.
