The latest release of Telegraf, version 1.15.1, is now available, featuring several key improvements and new plugins, including a new input plugin for NGINX Stream STS and Redfish, as well as new processors like Defaults Processor Plugin, Execd Processor Plugin, and Filepath Processor Plugin. The logparser input has been deprecated in favor of the tail input with data_format = "grok", while other fields used primarily for debugging have been removed from the splunkmetric serializer. Telegraf's --test mode now runs processors and aggregators before printing metrics, and official packages are built with Go 1.14.5. The release also includes new outputs, such as New Relic Output Plugin and Execd Output Plugin, and updates to existing plugins like SNMP, HTTP, and OPC-UA input plugins.
