In this chapter we have looked at various issues that impact the NetScaler system as a whole. We've learned how to identify issues with system level functions such as licensing, NTP, and SNMP. We've looked at what to do when certain processes unexpectedly drain system resources such as memory and CPU, and also how to deal with the system becoming unresponsive during crash and hang situations. Finally, we have reviewed the different build types available to you as a NetScaler owner.

In our final chapter we will take a detailed look at the various tools that NetScaler provides to help us during troubleshooting.
