| Description |
|
When two monitors are loaded the MaxScale installation the MaxScale does not accept any queries. The clients get ERROR 1045, failed to create a new session. The documentation is slightly off on this point in the configuration guide: https://github.com/mariadb-corporation/MaxScale/blob/master/Documentation/Getting-Started/Configuration-Guide.md#monitor I don't know if you consider this a bug or user error (why would the async replication need to be monitored on a galera cluster?) but I thought to report it as it caused some confiusion. If the issue is related to having any 2 monitors I think it should be fixed as you may want to monitor a cluster with two different plugins. |

Updated documentation with clearer separation of the two monitors and an added warning about multiple monitors monitoring the same servers. |

Currently MaxScale does not support multiple monitors monitoring the same servers so I'll resolve this as a documentation bug. |

it is better to put at least warning to log file |

Added a warning to the error log if more than one monitor is monitoring a server. |
