Splunk Lantern

Maintaining *nix systems

Scenario: In your organization, you have lots of *nix systems running critical applications or services. You need to monitor these systems to ensure the health of the associated apps and services, such as basic configuration, system diagnostics, file systems, and packages. You need to log and watch all these components, and ensure that appropriate technical staff are notified as quickly as possible if problems arise. With all these different concerns, you need Splunk searches that you can save and easily run on a schedule or as needed to keep your users up and running. You can use Splunk software to manage patches and updates to ensure all connected systems and related processes are running after the patch or update is complete. You can also use Splunk software for a number of other maintenance tasks, such as watching out for connectivity issues.

Prerequisites

To succeed in implementing this use case, you need the following dependencies, resources, and information.

How to use Splunk software for this use case

You can run many searches with Splunk software to manage *nix systems. Depending on what information you have available, you might find it useful to identify some or all of the following: 

Results

To maximize their benefit, the how-to articles linked in the previous section likely need to tie into existing processes at your organization or become new standard processes. These processes commonly impact success with this use case: 

  • Running regular backups
  • Maintaining tooling for software provisioning 
  • Maintaining tooling for configuration management 
  • Site reliability engineering processes

Measuring impact and benefit is critical to assessing the value of IT operations. The following are example metrics that can be useful to monitor when implementing this use case:

  • Mean time to resolution 
  • Mean time to root cause
  • Reduction in defects

Additional resources 

This use case is also included in the IT Essentials Learn app, which provides more information about how to implement the use case successfully in your IT maturity journey. In addition, these Splunk resources might help you understand and implement this use case:
