The newly released Dell Foglight 5.8.5 Application Performance Management (APM) product, which has migrated the built-in database from MySQL to PostgreSQL, can be analyzed for several reasons: one is a license issue, and after MySQL was acquired by Oracle, Business license has always been a problem, covering up, hiding, restricting the use of MySQL, the other is the stability of the product itself, security, performance and functionality, although different, but for technical personnel, PostgreSQL better control.
Hyperic, another open source APM product acquired by VMware, gave up support for MySQL a few years ago and fully supported PostgreSQL at the time, given the rationale for concentrating on the worthwhile product, with some 5 of the users we deploy, It has been running steadily for 6 years and has never had a performance problem.
Access to some open source applications are gradually supporting PostgreSQL, as a MySQL technician, also need to spend some time to understand psql, in fact, the difference is not very big.
It is also worth mentioning that JBoss and Tomcat two product selection, Dell Foglight has been using JBoss, and VMware Hyperic from JBoss to tomcat+activemq a few years ago, the boot speed and system capacity has greatly improved. Simple is beauty? Simple is stability?
VMWare Hyperic and Dell foglight have built-in databases as PostgreSQL
