I'm just looking for some clarification on the configuration of monitoring more than one mysql server or instance. I'm pretty new to Cacti as well so I'm working through all of it. I have set up the config.php for cacti with the mysql parameters for the local mysql db which is also the cacti server as well. In the mysql script provided for the percona plugin it says just above the argument variables that I can leave the configuration in the config.php blank otherwise it will override what is in the ss_get_mysql_stats.php script. My questions is if I was to do that wouldn't this cause a problem with how cacti access the local mysql db or could i just change the global.php for that purpose?
