Target customers: Developers, O&M personnel, and security analysts. Features released: After enabling the LogReduce feature in Logstore, you can use the log_reduce() function to perform pattern clustering for massive logs. Logs with similar structures are automatically grouped into the same category. This feature produces the following benefits. *Intelligence: Seamlessly applies to many log formats. For example, Log4j, delimiters, and JSON. *Fast analysis of massive logs: Completes analysis of hundreds of millions of logs within seconds. *Interaction: Signs signatures for pattern-clustered logs to trace back to raw logs. *Flexibility: Supports filtering logs based on the rules you set before pattern clustering. Supports comparing different versions of clusters (pattern-clustered logs). Supports manually adjusting the granularity of data (the number of patterns to categorize logs) for pattern clustering. You can quickly perform a smart analysis of massive logs to pinpoint the root cause of errors.
