The Splunk Product Best Practices team helped produce this response. Read more about use case examples Splunk® Platform Use Cases on Splunk Docs.

This use case enables system administrators to identify when logs generate error messages or exceptions so they can receive timely notifications and take timely action.

This use case is from the Splunk Essentials for Infrastructure Troubleshooting and Monitoring app. For more examples, see the Splunk Essentials for Infrastructure Troubleshooting and Monitoring on Splunkbase.

Load data

How to implement:

  1. Ingest application and operating system logs into Splunk Enterprise. Install the Splunk Add-on for Windows or *nix, and enable file and directory inputs for your entire infrastructure.
  2. Enable the File and Directory Inputs section of the configuration page.
  3. Enable or disable the input for the specified file or directory. Find the Splunk Add-on for Windows and Splunk Add-on for Unix and Linux on Splunkbase.

Data check: This use case depends on application logs and operating system logs.

Get insights

Find errors, failures and exceptions from all over your network using the Splunk Add-on for Windows or *nix. Search for error messages and exceptions so you can investigate and correct them.

Use the following search:

host=* (*error* OR *exception* OR *fail*)
| head 100
| table _time host sourcetype _raw
| sort host asc, _time desc

Best practice: In searches, replace the asterisk in index=* with the name of the index that contains the data. By default, Splunk stores data in the main index. Therefore, index=* becomes index=main. Use the OR operator to specify one or multiple indexes to search. For example, index=main OR index=security. See About managing indexes and How indexing works in Splunk docs for details.

Help

If no results appear, deploy the Add-ons to the search heads to access the knowledge objects necessary for simple searching. See About installing Splunk add-ons on Splunk Docs for assistance.
