Nagios and database

[romuloengt]

1) I need to know that the nagios works perfectly using oracle database. 2) The amount of monitored services will be 15000 every 5 minutes. The ndo2db and MySQL will account?

1) Are you referring to Nagios Core or Nagios XI? Normally NDOUtils with Core is only intended for MySQL, and XI uses a combination for MySQL and PostgreSQL, although in the former case there is one option that might work for Oracle usage (untested).

2) This depends entirely on the hardware specifications (CPU, RAM, disk speed) of your monitoring server.
