= FB_LOG_EVERY_MS
:mrdocs:

Issues a LOG(severity) no more often than every milliseconds. Example:

== Synopsis

Declared in `<folly/GLog.h>`

#define FB_LOG_EVERY_MS(severity, milli_interval)

----

== Description

FB_LOG_EVERY_MS(INFO, 10000) << "At least ten seconds passed" " since you last saw this.";

The implementation uses for statements to introduce variables in a nice way that doesn't mess surrounding statements. It is thread safe. Non‐positive intervals will always log.
