SQL Server Monitor:

The SQL monitor is included in the software package in the SqlMonitor folder and must be installed like the RmsServiceManager (requires the same SQL access data as the service manager) and can be installed on C:\Program Files\Rotronic\RMS.

The data is determined every 5 minutes and written to a separate «ServerMonitor» table in the database.

SQL and memory will be hidden if the SQL server and the RMS application server are the same.

If dot is green with "---" this is because the SQL monitor has no access to the database (connection string must be correct).
