Flik / practical guides
Practical log analysis guides
Investigate Kubernetes, Nginx and JSON logs with reproducible examples, real key sequences and explicit limits.
Find an error and the log lines before it
Use smart find to keep the events surrounding an error, refine the result and return to the original file order.
Count Nginx errors per hour
Filter failed Nginx requests, count occurrences by hour and distinguish HTTP statuses from error-log severity.
Flik, grep and jq: choose the right log workflow
Compare interactive log investigation with shell filtering and JSON transformation, using the same small example.
