+; into a local file.
+; Note: the default prefix is /var
+; Default Value: log/php7/error.log
+;error_log = log/php7/error.log
+
+; syslog_facility is used to specify what type of program is logging the

+; will be handled differently.
+; See syslog(3) for possible values (ex daemon equiv LOG_DAEMON)
+; Default Value: daemon
+;syslog.facility = daemon
+
+; syslog_ident is prepended to every message. If you have multiple FPM

+; Default Value: notice
+;log_level = notice
+
+; Log limit on number of characters in the single line (log entry). If the
+; line is over the limit, it is wrapped on multiple lines. The limit is for
+; all logged characters including message prefix and suffix if present. However
+; the new line character does not count into it as it is present only when

+; Default Value: 1024
+;log_limit = 4096
+
+; Log buffering specifies if the log line is buffered which means that the
+; line is written in a single write operation. If the value is false, then the
+; data is written directly into the file descriptor. It is an experimental

+; for some heavy logging scenarios. This option is ignored if logging to syslog
