- What is the purpose of moving averages?
Answer: Moving averages allow us to remove noise and smooth our data.
- What is the purpose of linear regression?
Answer: The purpose of linear regression is to identify trends – both positive and negative – in our time series.
- What are the extra steps required to render time charts in log analytics?
Answer: With log analytics, we must expand our time series using mv-expand and convert our values from dynamic data types to their specific data types. Then, we must project the columns we want to pipe to the render operator.
- 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 generate a smoother output, pass your data toseries_decompose_anomalies()to see if there are still any anomalies. The query to generate the graph in Figure 7.12 is as follows. You will need...
