I believe Zabbix's APM functionality would accomplish this pretty easily - pulling the data sources and then the active connections per data source should be reasonably straight-forward: ** When you POST to the api/tokens endpoint you get a JSON response that includes an array of the availableDataSources. ** For each of the available data sources you can GET api/session/data/<data source name>/activeConnections, which will give you the current active connections for that data source. If you're using the JDBC module to store your connections, you just need to query using an admin user account and that should give you all of the active connections. If you're using some other module for connections - JSON or LDAP, for example - this won't be quite so straight-forward, as there isn't an admin user who can see all of the active connections for all users, so this may not give the data you want. -Nick
