CachedLogger class abstract

Abstract logger that caches captured log messages in memory and periodically dumps them. Child classes implement saving cached messages to their specified destinations.

Configuration parameters

  • level: maximum log level to capture
  • source: source (context) name
  • options:
    • interval: interval in milliseconds to save log messages (default: 10 seconds)
    • max_cache_size: maximum number of messages stored in this cache (default: 100)

References

  • *:context-info:*:*:1.0 (optional) ContextInfo to detect the context id and specify counters source
