About multiple base monitors

SQL Monitor supports the installation of additional base monitors to monitor additional servers.

This option may be chosen because:

• a network's topology or geographical split means that not all servers can effectively be monitored from one base monitor
• monitoring a great many servers (200+), the load on a single base monitor may exceed desirable thresholds
• you have machines running in a DMZ.

Requirements for multiple Base Monitors

SQL Monitor is licensed by the number of machines being monitored, so splitting an existing license entitlement across multiple base monitors can be done at no additional cost.

• However, each Base Monitor will require it's own license, so, please contact sales to get an existing license split two or more keys.
• Each additional base monitor should be installed on a server conforming to the Hardware and performance guidelines.
• Each additional base monitor will require its own repository database to store data collected from the machines it monitors.
• Each base monitor should be kept at the same version of the software as the main basemonitor and website.
• Finally, it will be necessary for the server which runs the SQL Monitor web site to be able to contact all servers running base monitors via the TCP port specified in the base monitor installation. If there are firewall or similar restrictions between these servers, then they will need to be configured accordingly.

Configuring multiple Base Monitors 

Go to the Configuration tab under Application options, select Base Monitor connection:

2. Configure which machines to monitor from the same drop down list in the manage monitored servers screen:
   
   
   
   

General usage

Data collected from each of the Base Monitors will be shown in a merged view throughout SQL Monitor:

• Global overview will show tiles for each monitored instance on each Base Monitor.
• Server overview will be viewable for each monitored instance.
• Alert inbox will show merged view of alerts generated on each Base Monitor.
• Reports will show data summaries from each Base Monitors
