In this chapter, we learned about big data and its usage in analytics. We discussed Hadoop, Splunk, different architectures, and the integration of these tools with MicroStrategy. In the next chapter, we will be focusing on identifying and resolving the errors by analysing log files such as DSS log files. Apart from that, we will be covering different MicroStrategy tools such as diagnostic, performance logging, and health center tools, which help enable and disable traces for the purpose of troubleshooting and diagnosing problems.
