Configure

This setup guide will show you how to forward logs produced by CISCO Umbrella service to SEKOIA.IO by means of an Rsyslog transport channel.

Collect proxylogs files and send them to rsyslog

After configuring Umbrella Log Management with AWS S3, the logs you download will be gzipped CSVs in appropriate subfolder with the following naming format:

proxylogs/<year>-<month>-<day>/<year>-<month>-<day>-<hour>-<minute>.csv.gz

To send these logs to SEKOIA.IO, we suggest the use of the logger Unix command. For each unzipped file, use the following command line:

logger -t proxylogs -f <YYYY>-<MM>-<DD>-<hh>-<mm>-<xxxx>.csv

Configure the Rsyslog server

Please consult the Rsyslog Transport documentation to forward these logs to SEKOIA.IO.
