Universal Forwarder Disk Usage

New Member

HI Fellow Splunkers,

Need some help out here. What would be the minimum Disk Space required when installing a Universal Forwarder? or is there an ideal disk space for a universal forwarder? Just wanted to make sure the Forwarder itself doesn't utilize that much of Disk space when installed.

If default settings are used assuming full internal log retentions:
- Windows installation disk usage comes around : approx 450MB
- Linux installation disk usage comes around : approx 350MB

If you change the log-local.cfg and change the maxFileSize of each log to 5MB and maxBackupIndex to 1 , you can reduce the size on disk to 180MB ish (This means the splunk internal logs are rotated only once and each file is 5MB from a default of 25MB & 5 rotations)

We have requested specific filesystem for Linux Based clients to have 2GB for /opt/splunkforwarder as a build standard.
