zabbix 2.4.5 自定义key监控nginx
一、环境
ubuntu 14.04 LTS
zabbix 2.4.5
nginx/1.4.6
二、配置
1、确定Nginx HttpStubStatusModule模块已经安装，可以通过nginx -V来查看
nginx -V
nginx version: nginx/1.4.6 (Ubuntu)
built by gcc 4.8.2 (Ubuntu 4.8.2-19ubuntu1)
TLS SNI support enabled
configure arguments: --with-cc-opt='-g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2' --with-ld-opt='-Wl,-Bsymbolic-functions -Wl,-z,relro' --prefix=/usr/share/nginx --conf-path=/etc/nginx/nginx.conf --http-log-path=/var/log/nginx/access.log --error-log-path=/var/log/nginx/error.log --lock-path=/var/lock/nginx.lock --pid-path=/run/nginx.pid --http-client-body-temp-path=/var/lib/nginx/body --http-fastcgi-temp-path=/var/lib/nginx/fastcgi --http-proxy-temp-path=/var/lib/nginx/proxy --http-scgi-temp-path=/var/lib/nginx/scgi --http-uwsgi-temp-path=/var/lib/nginx/uwsgi --with-debug --with-pcre-jit --with-ipv6 --with-http_ssl_module --with-http_stub_status_module --with-http_realip_module --with-http_addition_module --with-http_dav_module --with-http_geoip_module --with-http_gzip_static_module --with-http_image_filter_module --with-http_spdy_module --with-http_sub_module --with-http_xslt_module --with-mail --with-mail_ssl_module
2、配置nginx文件
cd /etc/nginx/conf.d
sudo vim zabbix-monitor-nginx.conf
#Add the following into Nginx configuration:
server {
listen 10061;
location /nginx_status {
stub_status on;
access_log off;
allow 127.0.0.1;
deny all;
}
}
# reload nginx
sudo nginx -t && sudo nginx -s reload
3、测试nginx配置是否成功`curl http://127.0.0.1:10061/nginx_status` 获取数据
curl http://127.0.0.1:10061/nginx_status
Active connections: 1
server accepts handled requests
167 167 167
Reading: 0 Writing: 1 Waiting: 0
4、编写nginx status检测脚本
cd /etc/zabbix
sudo mkdir scripts
sudo vim scripts/nginx-check.sh
#Add the following bash codes
#!/bin/bash
##################################
# Zabbix monitoring script
#
# nginx:
# - anything available via nginx stub-status module
#
##################################
# Contact:
# vincent.viallet@gmail.com

# ChangeLog:

# Zabbix requested parameter
ZBX_REQ_DATA="$1"
ZBX_REQ_DATA_URL="$2"
# Nginx defaults
NGINX_STATUS_DEFAULT_URL="http://localhost:80/nginx_status"
WGET_BIN="/usr/bin/wget"
#
# Error handling:
# - need to be displayable in Zabbix (avoid NOT_SUPPORTED)
# - items need to be of type "float" (allow negative + float)
#
ERROR_NO_ACCESS_FILE="-0.9900"
ERROR_NO_ACCESS="-0.9901"
ERROR_WRONG_PARAM="-0.9902"
ERROR_DATA="-0.9903" # either can not connect / bad host / bad port
# Handle host and port if non-default
if [ ! -z "$ZBX_REQ_DATA_URL" ]; then
URL="$ZBX_REQ_DATA_URL"
else
URL="$NGINX_STATUS_DEFAULT_URL"
fi
# save the nginx stats in a variable for future parsing
NGINX_STATS=$($WGET_BIN -q $URL -O - 2> /dev/null)
# error during retrieve
if [ $? -ne 0 -o -z "$NGINX_STATS" ]; then
echo $ERROR_DATA
exit 1
fi
#

#

active_connections) echo "$NGINX_STATS" | head -1 | cut -f3 -d' ';;
accepted_connections) echo "$NGINX_STATS" | grep -Ev '[a-zA-Z]' | cut -f2 -d' ';;

*) echo $ERROR_WRONG_PARAM; exit 1;;
esac
exit 0
sudo chown -R zabbix:zabbix ./scripts/
sudo chmod +x nginx-check.sh
5、修改zabbix_agent.conf
sudo vi /etc/zabbix/zabbix_agent.conf
###Change the value of
UnsafeUserParameters=1
### Add User Parameters
UserParameter=nginx[*],/etc/zabbix/scripts/nginx-check.sh "$1" "$2"
sudo service zabbix-agent restart
6、导入Template nginx
Import nginx-template.xml, and link it to a host. Set the host macro {$NGINX_STATUS_URL} if needed.
nginx模板
