*** Important: Read upgrade Instructions and test add-on update before deploying to production *** There are changes to default indexes and .conf changes in version 6.0 of Splunk Add-on for Unix and Linux that can break an existing installation if upgrade instructions are not followed in detail. If an existing Splunk Add-on for Unix and Linux is being upgraded, please test in a non-production environment first. The Splunk Add-on for Unix and Linux works with the Splunk App for Unix and Linux to provide rapid insights and operational visibility into large-scale Unix and Linux environments. With its new pre-packaged alerting capability, flexible service-based hosts grouping, and easy management of many data sources, it arms administrators with a powerful ability to quickly identify performance and capacity bottlenecks and outliers in Unix and Linux environments.
