Why is JVM GC log analysis so challenging?

Management of large volumes of logs

Organizations prefer centralized log management to correlate different infrastructure and application logs. However, in modern distributed environments, logs can spiral out of control.

Time-consuming search and analysis

Traditional GC log analysis tools can get slow when sifting through a large volume of log data. The delayed performance makes it difficult to find the root cause of issues for troubleshooting.

Lack of integrated visualization tools

Limited visualization capabilities can impede detection of memory leaks, premature object promotions, long GC pauses, and other anomalies, and increase the time to resolve issues.
