accesslog-parser

Set of simple utilities created for reading and parsing nginx access.log file.

Components:

• reader - python like tail implementation. It allows continuous reading by storing file's inode and last reading end position.
• parse - per line parsing, inspired by this article

Data Format

Log format for parsing must be in Common Log Format.

For nginx web server, it is this configuration option:

log_format main '$remote_addr - $remote_user [$time_local] '
            '"$request" $status $body_bytes_sent "$http_referer" '
            '"$http_user_agent" "$http_x_forwarded_for"' ;  

Example

from parse import parse
from reader import Read

r = Read(follow="/var/www/nginx/access.log")

# read to the end of file
#  'status_save=True' means it will remember position of last reading
lines = r.read(status_save=True)    

# per line parsing
parsed_data = []
[parsed_data.append(parse(line)) for line in lines]
