About the Splunk App for Unix and Linux

The Splunk App for Unix and Linux provides data inputs, searches, reports, alerts, and dashboards for Linux and Unix management. You can monitor and troubleshoot *nix operating systems on potentially large numbers of systems from one place. Included are a set of scripted inputs for collecting CPU, disk, I/O, memory, log, configuration, and user data.

Use the Splunk App for Unix and Linux to:

• Get information about who's logged into your system, including last login times and unauthorized login attempts.
• Find out how much network throughput and bandwidth your system is using.
• Determine the status of current running processes on your system, and who is running them.
• Learn what software is installed on your system.

How does it work?

The Splunk App for Unix and Linux runs on top of a Splunk instance and gathers various system metrics, including:

• Hardware information - CPU type, count, and cache; hard drives; network interface cards, count, and memory, as well as CPU statistics.
• Disk information, including available disk space and associated input/output statistics for devices and partitions.
• Information about the configured network interfaces, including connections, routing tables, and TCP/UDP transfer statistics.
• User statistics, including last login times for system accounts, user attributes, and security-related information.
• Information about processes, the files they open, and other resources they use.

The app presents this data to you with pre-built reports and dashboards to give you full visibility into your system's operation.

How do I upgrade from a previous version?

While there is no supported upgrade path from version 4.6 of the Splunk App for Unix and Linux to this version, you can run both version 4.6 and this version simultaneously, if you so choose.

The installation package for this version of the app installs into a different directory than version 4.6. Once you have installed version 5.0, you can then configure this version of the app to use the same indexes and source types that the version 4.6 app uses.

For detailed installation instructions, read "Install the Splunk App for Unix and Linux" in this manual.

Caution: Do not attempt to install this version of the app into the same directory as the previous version. That is not supported and can render both versions of the app unusable.

Once you have configured and evaluated this version of the app, you can then remove the older version at a later date. No data loss will occur.

For information on any known issues in this version, review the release notes.
