Detailed tutorial on how to monitor Nginx/Tomcat/MySQL using Zabbix

Zabbix monitors Nginx

Machine A: zabbix server (192.168.234.128) Machine B: zabbix client (192.168.234.125)

Operation on machine B (zabbix client):

Edit the nginx virtual host configuration file:

[root@centos ~]# vi /etc/nginx/conf.d/default.conf

Add the following content inside server{}:

 location /nginx_status
 {
  stub_status on;
  access_log off;
  allow 127.0.0.1;
  deny all;
 }

Reload nginx configuration:

[root@centos ~]# nginx -s reload

test:

[root@centos ~]# curl http://127.0.0.1/nginx_status
Active connections: 1 
server accepts handled requests
 3 3 3 
Reading: 0 Writing: 1 Waiting: 0

#nginx status information is displayed

Status description:

Add monitoring script:

vi /usr/local/sbin/ngx_status.sh

Add the following content:

#!/bin/bash
url="http://127.0.0.1/nginx_status"
curl=/usr/bin/curl

# Check if the nginx process exists function ping {
 /sbin/pidof nginx | ​​wc -l 
}
# Check nginx performance function active {
 $curl $url 2>/dev/null| grep 'Active' | awk '{print $NF}'
}
function reading {
 $curl $url 2>/dev/null| grep 'Reading' | awk '{print $2}'
}
function writing {
 $curl $url 2>/dev/null| grep 'Writing' | awk '{print $4}'
}
function waiting {
 $curl $url 2>/dev/null| grep 'Waiting' | awk '{print $6}'
}
function accepts {
 $curl $url 2>/dev/null| awk NR==3 | awk '{print $1}'
}
function handled
 $curl $url 2>/dev/null| awk NR==3 | awk '{print $2}'
}
function requests {
 $curl $url 2>/dev/null| awk NR==3 | awk '{print $3}'
}
$1

Add permissions:

[root@centos ~]# chmod 755 /usr/local/sbin/ngx_status.sh

Edit the zabbix_agent configuration file:

[root@centos ~]# vi /etc/zabbix/zabbix_agentd.conf

Add in Option: UserParameter: UserParameter=nginx.status[*],/usr/local/sbin/ngx_status.sh $1

Restart the service:

[root@centos ~]# systemctl restart zabbix-agent

Test on machine A (server):

[root@zabbix ~]# zabbix_get -s 192.168.234.125 -k 'nginx.status[accepts]'

After the import is successful, select the monitored machine (machine B) on the host list page and link the template to start monitoring nginx

Zabbix monitors Tomcat

Machine A: zabbix server (192.168.234.128) Machine B: zabbix client (192.168.234.125)

Install zabbix-java-gateway on machine A:

[root@zabbix ~]# wget https://mirrors.tuna.tsinghua.edu.cn/zabbix/zabbix/4.0/rhel/7/x86_64/zabbix-java-gateway-4.0.14-1.el7.x86_64.rpm

[root@zabbix ~]# yum -y localinstall zabbix-java-gateway-4.0.14-1.el7.x86_64.rpm

Edit the gateway configuration file: 

[root@zabbix ~]# vi /etc/zabbix/zabbix_java_gateway.conf

Remove the comment symbol # from LISTEN_IP, LISTEN_PORT (listening port), and START_POLLERS (number of processes):

insert image description here

#LISTEN_IP defines the address of the monitored machine. If not specified, all machines will be monitored by default.

Edit the server configuration file:

[root@zabbix ~]# vi /etc/zabbix/zabbix_server.conf

Define the following 3 configuration parameters:

insert image description here

Start the zabbix-java-gateway service:

[root@zabbix ~]# systemctl start zabbix-java-gateway

Restart the zabbix-server service:

[root@zabbix ~]# systemctl restart zabbix-server

View the listening port:

[root@zabbix ~]# netstat -lntp |grep java
tcp6 0 0 :::10052 :::* LISTEN 8706/java

Enable JMX

Edit the tomcat configuration file on machine B:

[root@centos ~]# vi /usr/local/tomcat/bin/catalina.sh

Add the following content:

export CATALINA_OPTS="$CATALINA_OPTS -Dcom.sun.management.jmxremote
-Djava.rmi.server.hostname=192.168.234.125
-Dcom.sun.management.jmxremote.port=9999
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false"

#hostname defines the B machine address, port 9999 (default 12345)

Restart tomcat:

[root@centos ~]# /usr/local/tomcat/bin/shutdown.sh 

[root@centos ~]# /usr/local/tomcat/bin/startup.sh

View the listening port 9999:

[root@centos ~]# netstat -lntp |grep 9999
tcp6 0 0 :::9999 :::* LISTEN 25861/java

Enter the zabbix front-end page to add a host:

#Different from adding monitoring hosts in normal situations, the tomcat of monitoring machine B needs to configure the JMX interface

Template links to two JMX related templates:

Zabbix monitors MySQL

Machine A: zabbix server (192.168.234.128) Machine B: zabbix client (192.168.234.125)

zabbix_agent defines the configuration file for mysql monitoring: /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf

Log in to mysql on machine B and create a user:

mysql> grant usage,process,replication client on *.* to zamysql@'localhost' identified by 'zamysql';

Create the directory specified by the configuration file:

[root@centos ~]# mkdir /var/lib/zabbix

Create the my.cnf file:

[root@centos ~]# vi /var/lib/zabbix/.my.cnf

#Note that this file is a hidden file

Add the following content:

[mysql]
host=localhost
user=zamysql
password='zamysql'
socket=/tmp/mysql.sock

[mysqladmin]
host=localhost
user=zamysql
password='zamysql'
socket=/tmp/mysql.sock

Test on machine A:

[root@zabbix ~]# zabbix_get -s 192.168.234.125 -p 10050 -k mysql.ping
1
[root@zabbix ~]# zabbix_get -s 192.168.234.125 -p 10050 -k mysql.version
mysql Ver 14.14 Distrib 5.6.43, for linux-glibc2.12 (x86_64) using EditLine wrapper
[root@zabbix ~]# zabbix_get -s 192.168.234.125 -p 10050 -k mysql.size
10240
