Research direction
This issue requests adding support for Redis SLOWLOG GET command in Telegraf. The contributor should start by examining the existing Telegraf Redis input plugin (likely at plugins/inputs/redis/) to understand the plugin structure. Then implement a new or extend the existing plugin to collect slowlog entries using the SLOWLOG GET command. Reference the official Redis SLOWLOG documentation for the command response format. The issue comments may contain additional context; review them for any prior attempts or design decisions.
