mysqld is not producing binary log I'm trying to understand why mysqld is not writing binary log anymore...

[root@ip-10-179-155-214 mysql]# grep ^log-bin /etc/my.cnf
log-bin=mysql-bin
[root@ip-10-179-155-214 mysql]# ll mysql-bin.*

Things I'd check:


Are any changes happening? Binary log doesn't include SELECT queries, only changes. Compare the timestamp on files like ib_logfile*.
Are replication filters excluding changes being made?
Are sessions making changes while SQL_LOG_BIN=0 is suppressing binary logging, either globally as @RolandoMySQLDBA suggests, or else per session?
Disk is full?
You are looking at binlogs in the wrong directory?
