Knowing how to work with logs and where to look for information is critical when you're troubleshooting the system. A centralized syslog server helps in many ways with making log collection and management easier. You can also use tools such as ps and top to look into resource issues that the system may be having. In this chapter, we looked at the cron and atd services, each of which can be used for scheduling jobs. Using these tools, you can help track down problems that arise and look for trends of reoccurring issues. In the next chapter, we look at the kernel, the brains behind the Red Hat operating system.
