Troubleshooting NetScaler

By: Raghu Varma Tirumalaraju

Overview of this book

NetScaler is a high performance Application Delivery Controller (ADC). Making the most of it requires knowledge that straddles the application and networking worlds. As an ADC owner you will also likely be the first person to be solicited when your business applications fail. You will need to be quick in identifying if the problem is with the application, the server, the network, or NetScaler itself. This book provides you with the vital troubleshooting knowledge needed to act fast when issues happen. It gives you a thorough understanding of the NetScaler layout, how it integrates with the network, and what issues to expect when working with the traffic management, authentication, NetScaler Gateway and application firewall features. We will also look at what information to seek out in the logs, how to use tracing, and explore utilities that exist on NetScaler to help you find the root cause of your issues.

Summary


In this chapter, we discussed the tools available to you as an Administrator to help troubleshoot NetScaler issues. We began by looking at the nsconmsg binary logging utility, its syntax, and some useful examples. This was followed by the tracing utility nstrace and what proprietary information it can capture. We then looked at the different pieces of information that get picked up by the TechSupport file, before covering the Reporting and Dashboard pages.

In the second half of the chapter, we looked at Citrix Insight Services, which takes as input the TechSupport file and produces recommendations based on NetScaler best practices and highlights any deviations.

We concluded the chapter by briefly discussing Command Center and Insight Center, two tools that help to manage and gain better visibility into your Application environment. We also touched some quick troubleshooting tips for these tools.
