Access Log Analysis Read Locally

Open a static access log in your browser to review requests, HTTP errors, response timing, client signatures, and popular paths.

The file is read locally; parsed records may be stored in this browser.

01Nginx LogsOpen a static access log and inspect requests, HTTP errors, response bytes, and top paths.02Apache LogsReview requests, client IPs, status codes, and frequently requested URLs.03Caddy LogsRead JSON logs and check request time, traffic volume, and source breakdowns.04HAProxy LogsCheck backend traffic, response time, status codes, and heavy paths.

What You Can Do

This tool parses static Nginx, Apache, Caddy, and HAProxy access logs. The selected file is read locally rather than uploaded. You can filter requests, inspect status codes, search parsed records, and return to the original log evidence.

Choose a static access-log file to build a local snapshot of requests, unique client IPs, HTTP error rate, and response bytes. You can zoom the timeline, filter by method or status code, and search parsed records.

Use the snapshot to investigate outages, review crawler signatures, find high-volume clients, inspect failing URLs, and compare traffic around deployments or configuration changes.

Common Uses

01Check what happened during a traffic spike or outage.
02Find the top error URLs, status codes, and source IPs.
03Review crawler and bot signatures without uploading the log file.
04Compare busy paths, slow paths, and heavy bandwidth endpoints.
