Collect Logs for Linux
This procedure describes how to collect logs from Linux into Sumo Logic.
Sumo apps gather data from the log messages collected from sources by collectors. The Sumo app for Linux requires specific Linux log types, which are set up during the collector and source configuration process. The sections below list the required logs for:
- Ubuntu
- CentOS, Amazon Linux, and most Red Hat forks
Required logs for Ubuntu
The following logs, located in your Linux machine's /var/log folder, are required for using the Sumo app for Linux with Ubuntu:
- auth.log
- syslog
- daemon.log
- dpkg.log
- kern.log
Required logs for CentOS, Amazon Linux, and Red Hat
The following logs, located in your Linux machine's /var/log folder, are required for using the Sumo app for Linux with CentOS, Amazon Linux, and most Red Hat forks:
- audit/audit.log
- secure
- messages
- yum.log
Configure a collector
Configure an Installed Collector.
Configure a source
To configure a source for collecting Linux logs, you create a Local File Source. Following the instructions on Local File Source. When you define a Source Category for the source, we recommend something like: prod/os/linux. For more information about Source Categories, see see Best Practices.
