[collectd] Fwd: [5.1] Multiple mysql instances?
Hello, I'm trying to set up again collectd to handle more than one mysql instance per host. The problem is, that there is no information on how to do this - anywhere... When I start collectd, I get the warning: The read function mysql-mysql is already registered. Check for duplicate LoadPlugin lines in your configuration! However, the only place where I handle mysql is /etc/collectd.d/mysql.conf: LoadPlugin mysql Plugin mysql Database sqlone User backup Password Host 192.168.0.21 Database mysql #Socket /var/lib/mysql/sc-sqlcrit/mysql.sock /Database Database sqltwo User backup2 Password Database mysql Host 192.168.0.22 #Socket /var/lib/mysql/sc-sqlmain/mysql.sock /Database /Plugin I tried many combinations: using Host in first database and Socket in second one, using different users - nothing helped. Always only the first database is handled. Am I doing something wrong, or is collectd simply unable to handle two (or more) mysql servers?

I think the 'Database' directive *in* the block overrides the name in the 'Database' *definition*. This means that in your example, `sqlone` and `sqltwo` are both being overridden by `mysql`, thus yielding the error message. I remember banging my head on a hard surface too when trying to achieve the same goal. If I were you, I'd simply drop the `Database mysql` from your example, and it should work as-is. ___ collectd mailing list collectd@verplant.org http://mailman.verplant.org/listinfo/collectd

I remember banging my head on a hard surface too when trying to achieve the same goal. This issue should have been fixed in 5.1.1. The name of the Database definition is now used when registering the callback. The above configuration is perfectly fine in that case. If I were you, I'd simply drop the `Database mysql` from your example, and it should work as-is. No, this will only make the plugin not connect to any specific database. Before 5.1.1, you'd have to specify *different* database names (using the Database option within the Database block) in order to make this work.
