Most people are probably familiar with the word “grok” from Robert A. Heinlein’s novel A Stranger in a Strange Land, in which it is used to describe a deep, almost mystical understanding of something.

‍

Grok is also the name of a plugin for LogStash that enables you to parse and analyze log data using a syntax similar to regular expressions, but specialized for various log formats and fields. Like Heinlein’s term, LogStash Grok enables you to gain a deep, nuanced, and detailed understanding of your log data.

As powerful as it is, Grok patterns are notoriously difficult to write. This is likely why the Grok Pattern Reference topic in our product documentation consistently ranks at the top of our page, as SREs and developers are eager to find resources that aid their understanding of Grok. 

‍

The reason we have a Grok Pattern Reference is that we have also incorporated the power of Grok into our telemetry pipeline Parse processor. The Parse processor includes a Grok Pattern parser, where you can enter your pattern and then validate it against sample data. Our implementation also includes Mezmo-specific patterns that enable you to reach into the complexity of your log data and retrieve exactly what you want and need from it, in a way that is unique to Mezmo Telemetry Pipelines.
