Discussing scripted inputs

Scripted inputs are useful for indexing transient/temporary data that cannot be monitored through file/directory monitoring or use network inputs. Scripted inputs collect data from transient sources and then either write the collected data to a file or forward it directly to an indexer. Let’s go through some facts about this input type:

  • Scripted inputs require a UF agent or Splunk Enterprise instance (HF) to execute the scripts.
  • Data can be gathered from transient sources, such as operating system commands. The top, vmstat, netstat, and iostat commands all leverage this type of input, which is configured within the Splunk add-on for Unix and Linux available to download from http://splunkbase.splunk.com. The Windows technology add-on (TA) relies on this input type to gather Windows Active Directory (AD) logs, registry logs, WinEventLogs, and so on. Logs from remote APIs can also be pulled using scripts.
