Their Log Management solution offers Log data analysis and alerting. Dynatrace allows you to analyze log events across different parts of production and over longer periods of time. Dynatrace leverages artificial intelligence to correlate log messages and problems your monitors register. All of the data is used for root-cause analysis. You can also define custom rules and log metrics to receive notifications if any anomalies or passed thresholds occur. Dynatrace offers two products, Log monitoring v1 and Log monitoring v2 modes and they offer different approaches to log management, whereas the v2 is considered by Dynatrace as newer. V2 removes issues with logs with unrecognized timestamps and offers a generic log data ingestion engine. However, a lot of features are still missing in the v2, such as sensitive info masking, UI configuration files on a host, or on-demand access to log files on the monitored host. Dynatrace also offers a quite unique pricing model based on the Davis data units, also known as DDUs. Basically, each log record (line, message, entry) deducts 0.0005DDU from your available quota - 1 million log records multiplied by a DDU weight of 0.0005 consume a total of 500 DDUs.
