There was a problem hiding this comment.
I like the idea of adding the option to the plugin to keep a metrics context and periodically flush it but I don't think imposing it as the new default behavior is acceptable.
Please restore the original "immediate flush" code and modify your code to select between immediate and delayed flushing (maybe by defaulting the value of timer_interval_ms to 0 and interpretting 0 as immediate?).
Also, please rename timer_interval_ms to something more intuitive like flush_interval and use the FLB_CONFIG_MAP_TIME type instead (which automatically interprets units and makes it easier for the user).

This commit will change the log_to_metrics filter to use a timer based metric inject and not directly inject metrics on every incoming log record anymore. This will lower the overall load and memory consumption especially in high-volume and high-cardinality situations. Signed-off-by: Richard Treu <[email protected]>
