How to Disable Microseconds Precision (for a Performance Boost)
How to Disable Microseconds Precision (for a Performance Boost)¶
New in version 2.11: The use_microseconds
option was introduced in MonologBundle 2.11.
Setting the parameter use_microseconds
to false
forces the logger to reduce
the precision in the datetime
field of the log messages from microsecond to second,
avoiding a call to the microtime(true)
function and the subsequent parsing.
Disabling the use of microseconds can provide a small performance gain speeding up the
log generation. This is recommended for systems that generate a large number of log events.
