yes

  • SKOOR Engine/Collector software

  • Collector ringbuffer file, will use 1.5GB in default configuration

  • SKOOR Engine backup files

On a SKOOR Engine system, compressed DB backups are stored in /opt/eranger/server/backups by default. Additionally, /opt/eranger/tmp is used as temporary space for creating full database backups. If this is left unchanged then /opt/eranger needs to be at least as large as twice the database volume.

On a SKOOR Collector system, or if the above backup locations are linked to other filesystems, 5 GB are sufficient.

Database files. 50GB will be sufficient for a small system. Medium to large systems will need at least 100GB.

Separating the following two directories to separate disks or volumes can improve performance by up to 3 times:

/var/lib/pgsql/data/ng_tblspc/idx_space/
/var/lib/pgsql/data/ng_tblspc/tab_space/

These two directories make up most of the space taken up by the database tables and are usually about the same size, so each can be assigned half the space reserved for the database
