Questions
Before moving on to the next chapter, test your knowledge by answering these questions. The answers can be found at the back of this book:
- What is the purpose of moving averages?
- What is the purpose of linear regression?
- What are the extra steps required to render time charts in log analytics?
- In Figure 7.12, we rendered an anomaly chart to display the anomalies in the time series. Using
series_fir()
, generate a smoother graph without the anomalies. Once you have generated a smoother output, pass your data toseries_decompose_anomalies()
to see if there are still any anomalies. The query for generating the graph in Figure 7.12 is as follows. You will need to connect to the help cluster (https://help.kusto.windows.net/) to complete this exercise:let startTime = toscalar(demo_make_series1 | summarize min(TimeStamp)); let endTime = toscalar(demo_make_series1 | summarize max(TimeStamp)); let binSize = 1h; demo_make_series1 | make-series requests=count() default...
