Monitoring database management systems connected by a computer network

A non-transitory computer readable storage medium storing instructions that when executed by the computer processor cause the computer processor to execute instructions for performing steps comprising:

• maintaining a DBMS tracking table based on the information periodically received from a directory service, the DBMS tracking table identifying candidate servers for running a DBMS and storing status information describing DBMSs;
• for each candidate server identified in the DBMS tracking table:
• determining whether a DBMS is currently running on the server;
• and
• responsive to determining that a DBMS is currently running on the server, sending to the DBMS, instructions for installing a database agent configured to send a tracking message to the DBMS tracking system at startup time of the DBMS, the tracking message identifying the server on which the DBMS is running;
• receiving, by the DBMS tracking system, a tracking message from a database agent installed on a DBMS, the tracking message identifying the server on which the DBMS is currently running;
• updating the DBMS tracking table to indicate that the DBMS associated with the tracking message is running on the server identified in the tracking message;
• and
• sending the information stored in the DBMS tracking table for display.
