Performance issues

For this chapter, we will continue the scenario that we covered in Chapter 3, Troubleshooting a Web Application, where we are a new systems administrator at a new company. As we arrive to start our day, a fellow systems administrator asks us to look into a server being "slow."

When asked for details, the only information our colleague could provide was the hostname and the IP of the server deemed "slow." Our peer mentioned that a user reported it and that the user did not provide many details.

In this scenario, unlike in the scenario discussed in Chapter 3, Troubleshooting a Web Application we don't have much information to begin with. It also seems that we are not able to ask the user troubleshooting questions. It is not uncommon as a systems administrator to be required to troubleshoot an issue with very little information. In fact, this type of scenario is quite common.
