CachedTracer class abstract
Abstract tracer that caches recorded traces in memory and periodically dumps them. Child classes implement saving cached traces to their specified destinations.
Configuration parameters
- 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
- Implemented types
Constructors
- CachedTracer()
- Creates a new instance of the logger.
