Log Feeder

The Log Feeder component parses component logs. A Log Feeder is deployed to every node in the cluster and interacts with all component logs on that host. When started, the Log Feeder begins to parse all known component logs and sends them to the Apache Solr instances (managed by the Ambari Infra service) to be indexed.

By default, only FATAL, ERROR, and WARN logs are captured by the Log Feeder. You can temporarily or permanently add other log levels using the Log Search UI filter settings (for temporary log level capture) or through the Log Search configuration control in Ambari.
