A custom template
1. Create a template
1.1 cloned three
1.2 Direct created a trigger
1.3 Creating Graphics
The template is created, you can create a host again with the direct selection
Modify the template, can all take effect
For example: the modified time 30 days
2. Export Templates
3. Monitoring TCP11 states
Write zabbix profile
[root@web01 /etc/zabbix/zabbix_agentd.d]# cat zbx_tcp.conf
UserParameter=ESTABLISHED,netstat -ant|grep -c 'ESTABLISHED'
UserParameter=SYN_SENT,netstat -ant|grep -c 'SYN_SENT'
UserParameter=SYN_RECV,netstat -ant|grep -c 'SYN_RECV'
UserParameter=FIN_WAIT1,netstat -ant|grep -c 'FIN_WAIT1'
UserParameter=FIN_WAIT2,netstat -ant|grep -c 'FIN_WAIT2'
UserParameter=TIME_WAIT,netstat -ant|grep -c 'TIME_WAIT'
UserParameter=CLOSE,netstat -ant|grep -c 'CLOSE'
UserParameter=CLOSE_WAIT,netstat -ant|grep -c 'CLOSE_WAIT'
UserParameter=LAST_ACK,netstat -ant|grep -c 'LAST_ACK'
UserParameter=LISTEN,netstat -ant|grep -c 'LISTEN'
UserParameter=CLOSING,netstat -ant|grep -c 'CLOSING'3.2. Restart zabbix-agent
[root@web01 ~]# systemctl restart zabbix-agent.service 3.3. Test Monitor items
Use zabbix-get command to test
[root@m01 ~]# yum install zabbix-get.x86_64 -y
[root@m01 ~]# zabbix_get -s 10.0.1.7 -k ESTABLISHED
2
[root@m01 ~]# zabbix_get -s 10.0.1.7 -k LISTEN
124. import file template
The host associated template file
6. View the latest data
7. View graphics
Second, the custom template to monitor the state of nginx
1. Turn on the monitor page and access test
[root@web01 ~]# cat /etc/nginx/conf.d/status.conf
server {
listen 80;
server_name localhost;
location /nginx_status {
stub_status on;
access_log off;
}
}
[root@web01 ~]# curl 127.0.0.1/nginx_status/
Active connections: 1
server accepts handled requests
6 6 6
Reading: 0 Writing: 1 Waiting: 0 2. Prepare nginx monitor the status of the script
[root@web01 /etc/zabbix/zabbix_agentd.d]# cat nginx_monitor.sh
#!/bin/bash
NGINX_COMMAND=$1
CACHEFILE="/tmp/nginx_status.txt"
CMD="/usr/bin/curl http://127.0.0.1/nginx_status/"
if [ ! -f $CACHEFILE ];then
$CMD >$CACHEFILE 2>/dev/null
fi
# Check and run the script
TIMEFLM=`stat -c %Y $CACHEFILE`
TIMENOW=`date +%s`
if [ `expr $TIMENOW - $TIMEFLM` -gt 60 ]; then
rm -f $CACHEFILE
fi
if [ ! -f $CACHEFILE ];then
$CMD >$CACHEFILE 2>/dev/null
fi
nginx_active(){
grep 'Active' $CACHEFILE| awk '{print $NF}'
exit 0;
}
nginx_reading(){
grep 'Reading' $CACHEFILE| awk '{print $2}'
exit 0;
}
nginx_writing(){
grep 'Writing' $CACHEFILE | awk '{print $4}'
exit 0;
}
nginx_waiting(){
grep 'Waiting' $CACHEFILE| awk '{print $6}'
exit 0;
}
nginx_accepts(){
awk NR==3 $CACHEFILE| awk '{print $1}'
exit 0;
}
nginx_handled(){
awk NR==3 $CACHEFILE| awk '{print $2}'
exit 0;
}
nginx_requests(){

exit 0;
}

esac3. Write zabbix monitoring profile
[root@web01 ~]# cat /etc/zabbix/zabbix_agentd.d/nginx_status.conf
UserParameter=nginx_status[*],/bin/bash /etc/zabbix/zabbix_agentd.d/nginx_monitor.sh $1
[root@web01 ~]# systemctl restart zabbix-agent.service4. Use Value zabbix_get
[root@m01 ~]# zabbix_get -s 10.0.1.7 -k nginx_status[accepts]
75. Template Import
6. Link templates
7. View data
Third, custom templates to monitor the state of php
1. Open the monitoring page
[root@web01 ~]# tail -1 /etc/php-fpm.d/www.conf
pm.status_path = /php_status
[root@web01 ~]# cat /etc/nginx/conf.d/status.conf
server {
listen 80;
server_name localhost;
location /nginx_status {
stub_status on;
access_log off;
}
location /php_status {
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME html$fastcgi_script_name;
include fastcgi_params;
}
}
[root@web01 ~]# nginx -t

[root@m01 ~]# zabbix_get -s 10.0.1.7 -k php-fpm["total processes",http://127.0.0.1/php_status]
55. Template Import
You need to modify the template in the macro configuration after importing
Four, WEB monitoring
Demand, monitor page status code

2问题原因：
zabbix_agent是以普通用户zabbix运行的，而普通用户执行netstat -antp时会有警告，网上查找发现只要不是用p参数就可以以普通用户运行
解决方案：
监控脚本里的命令修改为netstat -ant
