Collections

By default there are 3 main storage layer abstractions in Log Search:

  • Service logs (default name: hadoop_logs)
  • Audit logs (default name: audit_logs)
  • Metadata (default name: logsearch_metadata)

Service logs collection is responsible to store most of the logs (by type), except audit related data, for those use the audit logs collection. The metadata collection is used to store Log Search UI related (dynamic) configurations/settings.

Schema fields

Minimal required service log fields in Solr to make it work with the UI:

  • id (string, unique - identifier for Solr doc)
  • log_message
  • type (string - log type)
  • logtime (timestamp)
  • seq_num (numeric - sequence number for log events, useful to not sort only by date)
  • level (string - log level for logs, e.g.: WARN)
  • host (string)
  • cluster (string)

Minimal required audit log fields in Solr to make it work with the UI:

  • id (string, unique - identifier for Solr doc)
  • evtTime (timestamp)
  • repo (string - represents the audit source type)
  • seq_num (numeric - sequence number for log events, useful to not sort only by date)

see more: Audit logs schema

Fields for metadata:

  • id (string, unique - identifier for Solr doc)
  • name (string - metadata identifier)
  • username (string - for identify user related data)
  • type (string - type of the metadata)
  • value (string - can be anything)

Customize field names on the Log Search UI

Field name labels on the UI can be customized in logsearch.properties, see: AMBARI-22842
