Wish to monitor Mysqld but once I add, it times out and I get a call. IP plus:3306

Sorry for such a delayed reply,

If your SQL server is exposed to the public internet our system should be able to ping it with no problem. In most cases, however, SQL servers are behind a router/firewall as it is very insecure to expose an SQL server to the public.

To monitor servers that are behind a router/firewall you can use our Local Pinger which can be downloaded from the Control Panel. There is also a User Guide available on the Control Panel which will can help you in deploying the Local Pinger in your network.
