The ndo2db MySQL backend, in short ndomy backend, is used to fetch Nagios information like status and configuration data via a MySQL database. The Nagios addon called ndoutils stores all information which are present in a running Nagios in a MySQL database. This database is being queried by the NagVis ndomy backend.
You can use the following parameters to configure an ndomy backend:
| Value | Default | Description |
|---|---|---|
| dbhost | localhost | Hostname of the NDO Database |
| dbport | 3306 | Port of the NDO Database |
| dbname | db_nagios | Name of the NDO Database |
| dbuser | root | Username for Database Access (only needs read permissions) |
| dbpass | root | Password for Database Access (only needs read permissions) |
| dbprefix | nagios_ | Prefix of the tables in NDO Database (like defined in ndo2db.cfg) |
| dbinstancename | default | Name of the Nagios instance in NDO Database (like defined in ndomod.cfg) |
| maxtimewithoutupdate | 180 | Maximum delay in seconds after last update in NDO. NagVis will report Nagios is not running if the delay is reached |
There are also some general parameters. You can read about them in main configuration format description.
Note: The above should be possible with the IDOUtils of Icinga as well so replace "NDO", "ndo2db.cfg", and "ndomod.cfg" with "IDO", ido2db.cfg", and "idomod.cfg", respectively.
