zabbix-nginx-stats

Simple script to import basic nginx statistics into zabbix. It parses the log file (currently only supports one basic format) and pushes the data into zabbix. It is written in perl with a small bash wrapper script which uses logtail.

Synced values include (all since last execution):

Request Count
Request count by status code
Request Time: Average, Mean, Median, 90%, 80% and 25% lines
Upstream Response Time (Same as Request Time)
Body Bytes Sent: Average, Sum

The default zabbix template has preconfigured triggers to warn on 5 errors (status code 500, 503 and 403) and graphs for request time and request count by status.

Installation/Configuration:

checkout from github

install dependencies

logtail2 (debian: apt-get install logtail)
Perl
Statistics::Descriptive, Date::Parse and File::Temp
- for debian: install packages libstatistics-descriptive-perl libtimedate-perl

configure logfile output:

     log_format timed_combined '$remote_addr $host $remote_user [$time_local]  '
                '"$request" $status $body_bytes_sent '
                '"$http_referer" "$http_user_agent" $request_time $upstream_response_time $pipe';
                
     access_log /var/log/nginx/access.log timed_combined;

Import template zbx_template_nginx.xml

configure crontab to run every 10 minutes:

8-59/10 * * * *   root      /home/scripts/zabbix-nginx-stats/zabbix-nginx-stats-runner.sh

watch results coming in.

Roadmap

Allow pushing to multiple zabbix hosts - If you are using nginx as proxy in front of various applications it should be possible to filter these applications to get separated statistics.

Move 501, 502 and 503 errors to separate counters, do not alert on 403/404

Due to high random traffic on the internet these days there is little point into alerting on 403/404 errors. On the other hand 502, 503 and 504 errors are pretty common nowadays when traffic to modern web applications is proxied through nginx.
