Use the LogReduce button and operator to quickly assess activity patterns for things like a range of devices or traffic on a website. :::important The `summarize` operator has been renamed to `logreduce` to match the **LogReduce** button on the **Messages** tab. Both operators will continue to work in search queries as synonyms for a limited time. We recommend that you rewrite saved queries replacing summarize with LogReduce. ::: :::training Micro Lesson Watch our video on LogReduce. ::: In this section, we'll introduce the following concepts:
Allows you to quickly assess activity patterns for things like a range of devices or traffic on a website.
Group messages with similar structures and patterns, providing insight into specific keywords or time range.
Clusters JSON logs based on keys providing an at-a-glance summary of patterns in logs based on their schema while ignoring specific values.
Clusters JSON logs using the values of keys.
Displays a numerical score for a signature, predicting which signatures could be most meaningful.
Influence the algorithm by editing a signature to increase or decrease your results granularity.
