In this tutorial, we will be covering the process of instilling and using
apachetop, a command line-based piece of software that allows real-time traffic monitoring for
Nginx web servers. It it also expected to work with other web servers such as
apachetop allows a server administrator to view visitors, their IP Addresses, accessed URLs, referrers etc… — all in real time.
apachetop package is available under the EPEL Yum Repository:
sudo yum -y install epel-release sudo yum clean all sudo yum -y update sudo yum -y install apachetop
The above command will launch
apachetop and will will try to find the access log of an Apache server in its location:
If you customized your vhost to use a custom log path, you will need to specify the custom path using the
-f parameter as follows:
sudo apachetop -f /var/log/nginx/wordpress_http_access.log
apachetop will display the statistics for the visits from the last 30 seconds. You can modify that using the
-T parameters as follows:
sudo apachetop -f /var/log/nginx/wordpress_http_access.log -H 1000
The command above will display stats on the last 1000 hits.
sudo apachetop -f /var/log/nginx/wordpress_http_access.log -T 600
The command above will display stats on the last 600 seconds.
On the top of the screen, you will find a short summary for visits, stats etc…
last hit: 13:59:43 atop runtime: 0 days, 00:42:31 14:02:14 All: 19 reqs ( 0.0/sec) 111.3K ( 151.8B/sec) 6001.0B/req 2xx: 12 (63.2%) 3xx: 7 (36.8%) 4xx: 0 ( 0.0%) 5xx: 0 ( 0.0%) R ( 30s): 0 reqs ( 0.0/sec) 0.0B ( 0.0B/sec) 0.0B/req 2xx: 0 ( 0.0%) 3xx: 0 ( 0.0%) 4xx: 0 ( 0.0%) 5xx: 0 ( 0.0%)
The first line consists of:
The second and the third lines provide statistics on all visits since the apachetop program gets started. 2xx, 3xx, 4xx, and 5xx represent corresponding web server response codes.
The fourth and the fifth lines provide the same statistics as the two lines above, except that they focus on visits in a specified scope which is 30 seconds by default.
Below the summary is a list of all visits and requests:
REQS REQ/S KB KB/S URL 1 0.10 9.8 1.0/ 1 0.14 13.6 1.9*/2016/01/25/hello-world/ 2 0.18 18.2 1.7 /category/uncategorized/ 1 0.07 9.9 0.7 /2016/01/
The asterisk represents a Selected Line.
apachetop contains built-in shortcuts:
