Dear Suresh, Thank you for your comment. Yes, the mentioned Java plugins do not scale to well when monitoring hundreds of DB's, as you point out. In some scenarios however, say in a medium size environment with 50+ databases, but all from a different vendor: DB2, Oracle, MS-SQL, MySQL, Postgres and Sybase, they are helpful to get a *basic* DB monitoring up and running. Trying to monitor such a varied DB environment with a single Nagios instance AND using plugins with native DB client installations can quickly overwhelm Nagios admins. Not to mention that monitoring MS-SQL DB's with a native driver on Linux is extremly hard. Java DB drivers and plugins on the other hand are commonly available for all but the most exotic DB's, fairly easy to deploy, and provide simple and standardized way to monitor the most critical data in such a DB Zoo. Some are actually searching for such a specific solution and are glad to find there is A) the option to use Java, and B) there is already a example plugin they can build upon and extend. Experts running large-scale, enterprise DB farms are usually at a level to write and adapt plugins whithout any help. ;-)
