InnoDB log buffer unflushed is wrong #10

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
The InnoDB log buffer unflushed in the InnoDB Log graph shows spikes that
reach about twice as large as the log buffer size.  This is impossible,
since the unflushed bytes can't be larger than the log size.

Screenshot is attached.

Should $status['unflushed_log']
         = max($status['unflushed_log'], $status['innodb_log_buffer_size']);

be min() instead for now then?

I think this must be related to issue 36 and issue 41

the unflushed_log rrd is a COUNTER, it should be a GAUGE!

There is sponsorship for the fix in Percona customer issue 7963.

This is fixed in the template definition file in r418, but it's not really fixed
until there are instructions about upgrading and fixing the RRD file on the 
wiki.
