AIOps Labs

AIOps Labs is a part of Machine Learning in Kibana which provides features that use advanced statistical methods to help you interpret your data and its behavior.

Explain log rate spikes is a feature that uses advanced statistical methods to identify reasons for increases in log rates. It makes it easy to find and investigate causes of unusual spikes by using the analysis workflow view. Examine the histogram chart of the log rates for a given data view, and find the reason behind a particular change possibly in millions of log events across multiple fields and values.

You can find explain log rate spikes under Machine Learning > AIOps Labs where you can select the data view or saved search that you want to analyze.

Select a spike in the log event histogram chart to start the analysis. It identifies statistically significant field-value combinations that contribute to the spike and displays them in a table. You can optionally choose to summarize the results into groups. The table also shows an indicator of the level of impact and a sparkline showing the shape of the impact in the chart. Hovering over a row displays the impact on the histogram chart in more detail. You can inspect a field in Discover by selecting this option under the Actions column. You can also pin a table row by clicking on it then move the cursor to the histogram chart. It displays a tooltip with exact count values for the pinned field which enables closer investigation.

Brushes in the chart show the baseline time range and the deviation in the analyzed data. You can move the brushes to redefine both the baseline and the deviation and rerun the analysis with the modified values.

Log pattern analysis helps you to find patterns in unstructured log messages and makes it easier to examine your data. It performs categorization analysis on a selected field of a data view, creates categories based on the data and displays them together with a chart that shows the distribution of each category and an example document that matches the category.

You can find log pattern analysis under Machine Learning > AIOps Labs where you can select the data view or saved search that you want to analyze.

Select a field for categorization and optionally apply any filters that you want, then start the analysis. The analysis uses the same algorithms as a machine learning categorization job. The results of the analysis are shown in a table that makes it possible to open Discover and show or filter out the given category there, which helps you to further examine your log messages.
