tail-uwsgi-log 0.0.4

Tail several uwsgi log files and send an email when error occurs.

What does this package do

Tail log files on your server and report by email if error occurs.

By default, the regex pattern was set for default uwsgi logs.

Install

pip install tail_uwsgi_log

Usage

tail_uwsgi_log -c your_config_filepath.ini

Configs

The config file provides infomations needed to send an email and log-files to tail.

For example:

; section name startswith 'log' would be interpreted as logfile config
[log-myapp1]

; log file path
filepath = your_log_filepath

; wait_time for tail command, the thread will sleep and wait
; the wait_time should be small if the server is busy and generates log lines quickly
wait_time = 0.5

; the regex pattern to read the log line, the line doesn't match this regex will be recorded as innormal
pattern = 

; mail settings
mail_recipients = [e-mail], [e-mail]

mail_host = smtp.qq.com
mail_port = 465
mail_sender = your_email_address
mail_password = your_password

To tail several log files at the same time, we could set several sections on config files, the section name should start with 'log'.

For mail settings, we could use a section named 'mail' to set default value. The default value will be used if not set in log section.

For example:

[log-myapp1]
filepath = your_log_filepath1
wait_time = 0.5
pattern = 
mail_recipients = [e-mail], [e-mail]

[log-myapp2]
filepath = your_log_filepath2
wait_time = 1
pattern = 
mail_recipients = [e-mail], [e-mail]

[mail]
mail_host = smtp.qq.com
mail_port = 465
mail_sender = your_email_address
mail_password = your_password

The default regex pattern to match the logline was for default uwsgi logs, which is:

pattern = r'''\]\ (?P<ip>.*?)\ (.*)\ {.*?}\ \[(?P<datetime>.*?)\]\ (?P<request_method>POST|GET|DELETE|PUT|PATCH)\s
            (?P<request_uri>[^ ]*?)\ =>\ generated\ (?:.*?)\ in\ (?P<resp_msecs>\d+)\ msecs\s
            \(HTTP/[\d.]+\ (?P<resp_status>\d+)\)'''

The 'resp_status' in the pattern is important, which will be used as a signal.

When the resp_status is 500, an email will be sent with all innormal log lines recorded before.
