"Grepe" is a playful nod to "Grep," a robust pattern matching tool in GNU, with the added twist of incorporating "e" for "eseries." This tool serves as a valuable resource when traditional time-series logging tools such as Loki, Splunk, or Datadog aren't available due to cost constraints or other limitations.
Designed to be used directly in the terminal, Grepe offers a simple yet effective solution for visualizing time-series patterns extracted from log data. By leveraging regular expressions and a hash map, it efficiently generates bar charts directly within the terminal interface.
In practical terms, Grepe proves particularly useful for scenarios where monitoring for specific events, such as requests with a status code of "400," is necessary but conventional time-series logging tools aren't feasible. With Grepe, users can gain insights into these patterns in their log data without the need for additional, potentially costly observability solutions.
