Script untuk monitoring statistics Nginx relatif mudah di instalasi dan di konfigurasi. Kita perlu melakukan langkah berikut untuk memperoleh gambar statistik dari server nginx.
Ubah konfigurasi file ngix dan tambahkan kalimat berikut
vi /etc/nginx/sites-enabled/default
http {
…
server {
listen SOME.IP.ADD.RESS;
…
location /nginx_status {
stub_status on;
access_log off;
allow SOME.IP.ADD.RESS;
deny all;
}
…
}
…
}
Test file konfigurasi
/etc/init.d/nginx stop /usr/sbin/nginx -t
the configuration file /etc/nginx/nginx.conf syntax is ok configuration file /etc/nginx/nginx.conf test is successful
Jika ada error tentang stub_status, check nginx. Nginx harusnya di konfigurasi dengan —-with-http_stub_status_module. Jika semua OK menggunakan shell lakukan test
# GET http://hostname.anda/nginx_status
Active connections: 1 server accepts handled requests 1 1 1 Reading: 0 Writing: 1 Waiting: 0
Download perl script: rrd_nginx.pl dan jadikan executable
cd /usr/local/src/ wget http://kovyrin.net/files/mrtg/rrd_nginx.pl.txt mv rrd_nginx.pl.txt rrd_nginx.pl chmod +x rrd_nginx.pl
Install rrd tools
apt-get install rrdcollect rrdtool rrdtool-tcl librrds-perl libgd-gd2-perl wget
mkdir /var/lib/nginx/rrd mkdir /var/lib/nginx/rrd/html
Ubah setting di rrd_nginx.pl agar script tahu dimana menyimpan rrd-base dan image
vi /usr/local/src/rrd_nginx.pl
#!/usr/bin/perl use RRDs; use LWP::UserAgent; # define location of rrdtool databases my $rrd = ‘/var/lib/nginx/rrd’; # define location of images my $img = ‘/var/lib/nginx/rrd/html’; # define your nginx stats URL my $URL = “http://hostname.anda/nginx_status”;
Selanjutnya setup cron
crontab -e
0 * * * * /usr/local/src/rrd_nginx.pl
Jika semua persiapan telah dilakukan dengan baik maka kita akan melihat image di folder
/var/lib/nginx/rrd/html
