Hi all,
I need to set up mysql monitoring graphs in Graphite. I am able to monitor
basic system metrics after runnning example-client.py that comes with
graphite installation.
when i m looking for mysql plugin for graphite , i find
MySQLPerfCollector.py but when i am running it after installing
So I created a new test box on AWS, and just did one upgrade from
5.0.96 to 5.1, like I did before and replication will not work from a
master with 5.0.96 to a slave with 5.1.68
I keep getting Error 1062, Duplicate Entry for key
I get no errors when I do a mysql_upgrade, all comes back ok.
I
update the master ASAP in a short timeframe too
and re-init replication if needed
normally both should have exactly the same version
the slaves must be updated first because otherwise
a master may write instructions in the binlog the older
slave does not undersatdn at all, but as said normally
Unfortunately that is not possible at the moment, I have 6 slaves off
the one master, also I want to test it as much as possible before
upgrading the master.
Is the only way to really fix this is to upgrade master? I thought
you can replicate from master - slave if version is higher on slave,

just not the other way around?
normally no
but take a look at the changelogs of myslq in the last years

They are both right. It is a matter of how many decimal places you want to
display:
mysql SELECT 365 * 1.67 * ( 1 - 0.10);
+--+
| 365 * 1.67 * ( 1 - 0.10) |
+--+
| 548.5950 |
+--+
1 row in set (0.00 sec)
* Smells like some huge LONGTEXTs were INSERTed, then DELETEd. Perhaps just a
single one of nearly 500M.
* Yes, there is an impact on full table scans -- it has to step over the empty
spots. Or maybe not -- one big cow chip of 500MB would be easy to leap over.
* OPTIMIZE TABLE is the
It is safer to have the Slave be a newer version.

Unless someone else here is using Graphite (I've never even heard of it, tbh) I
think this may be something for the Graphite support channels, instead.
