Nagios Support Forum

Hi All,

Could you please let me know what would be the default port which would be used for communication between inside components of Nagios XI .

Example port being used for communication between NDOUtils -> My SQL

NagiosSQL -> Configuration Files

Nagios core -> NDOUtils

Nagios XI -> PostgreSQL.

Please update the attachment with relevant port numbers.

Please ignore internal scripts component of the image.

Postgresql: 5432
MySQL: 3306

Flow of information:
Ndoutils -> MySQL
Nagios XI -> NagiosQL -> 3306:MySQL -> configuration files

Aside from MySQL and Postgres, the other components you mentioned don't listen on ports - they either use Unix Domain Sockets or don't listen at all. Let me know if you have any questions, thanks!
