Top Error Endpoints

Given an access log file, find the request paths that returned the most 5xx (server error) responses.

Input

A single argument: the path to a log file. Each line looks like:

10.0.0.1 - - [10/Aug/2026:10:00:01] "GET /api/users HTTP/1.1" 500 123

Output

The top 3 request paths by number of 5xx responses, one per line, in the form:

<count> <path>

Ordered by count descending; ties broken by path ascending. If fewer than 3 distinct paths have any 5xx responses, print only that many lines. Paths with zero 5xx responses are not printed.

Constraints

• The log file has at most 100,000 lines.
• Space-delimited fields; from the end of the line the fixed order is always: method, path, protocol, status code, response size.
• A 5xx response is any status code from 500 to 599.

Example

Input:

10.0.0.1 - - [10/Aug/2026:10:00:01] "GET /api/users HTTP/1.1" 500 123
10.0.0.2 - - [10/Aug/2026:10:00:02] "GET /health HTTP/1.1" 200 12
10.0.0.3 - - [10/Aug/2026:10:00:03] "POST /api/login HTTP/1.1" 503 43

Output (abbreviated — a larger log producing these totals):

17 /api/login
12 /api/users
4 /api/orders
