Bug Description

I run mysql-mmm version 2.0.6

While trying to solve an other problem I just saw this line in the info log :

2009/06/10 13:19:55 No binary found for killing hosts (/usr/bin/mysql-mmm//monitor/kill_host).

From what I see since version 2.0.4 we can provide kill_host_bin in the config file. The documentation isn't really claer about what kill_host is supposed to really do. Could you please at least give an example or introduce a default script in a next release.

I understand that this is low in priority.

Is it critical if the binaries don't exists ?

Sorry, I've no sample binary for this. Quote from Alexey Kovyrin:
"It could be a simple ssh + iptables call to close mysql from the world by dropping all port 3306 connections."

It could also be a script that tells a UPS to poweroff the failed server.

It's just a way to assure, that the failed host really is not used anymore.

 I don't consider a missing kill_host binary critical. (otherwise there would be a check for this during monitor startup).
