Zabbix Monitoring Nginx

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

Operate on machine B (zabbix client):

Edit the nginx virtual host profile:

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

Add the following to 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_statusActive connections: 1 server accepts handled requests 3 3 3 Reading: 0 Writing: 1 Waiting: 0

# nginx status message is displayed

Status description:

Add a monitoring script:

Vi / usr/local/sbin/ngx_status.sh

Add the following:

#! / bin/bashurl= "http://127.0.0.1/nginx_status"curl=/usr/bin/curl# detects whether function ping {/ sbin/pidof nginx | wc-l} # detects 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: UserParameter=nginx.status [*], / usr/local/sbin/ngx_status.sh $1 at Option:UserParameter

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]'6

Create an .xml file locally and add the following: (file name customization)

Click configure → template → Import on the zabbix frontend page:

# just import the xml file you just created

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

Zabbix Monitoring Tomcat

A machine: zabbix server (192.168.234.128) B machine: 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 # of LISTEN_IP, LISTEN_PORT (listening port) and START_POLLERS (number of processes):

# LISTEN_IP defines the address of the monitored machine, and does not specify default listening to all machines

Edit the server configuration file:

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

Define the following 3 configuration parameters:

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 javatcp6 00:: 10052: * LISTEN 8706/java

Turn on JMX

Edit the tomcat configuration file on machine B:

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

Add the following:

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 address of machine B, port 9999 (default 12345)

Restart tomcat:

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

View listening port 9999:

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

Go to the zabbix front-end page to add hosts:

# different from adding monitoring hosts, tomcat of monitoring machine B needs to be configured with JMX interface

Templates link to two templates related to JMX:

When the JMX icon turns green, the configuration is successful:

Zabbix Monitoring MySQL

A machine: zabbix server (192.168.234.128) B machine: 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 to 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 a my.cnf file:

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

# Note that the file is hidden

Add the following:

[mysql] host=localhostuser=zamysqlpassword='zamysql'socket=/tmp/ mysql.sock[mysqladmin] host=localhostuser=zamysqlpassword='zamysql'socket=/tmp/mysql.sock

Test on the A machine:

[root@zabbix] # zabbix_get-s 192.168.234.125-p 10050-k mysql.ping1 [root@zabbix ~] # zabbix_get-s 192.168.234.125-p 10050-k mysql.versionmysql Ver 14.14 Distrib 5.6.43, for linux-glibc2.12 (x86x64) using EditLine wrapper [root@zabbix ~] # zabbix_get-s 192.168.234.125-p 10050-k mysql.size10240

# data has been obtained successfully

Add hosts to the zabbix front-end page:

Select DB mysql for monitoring template:

Changing the ZBX standard to green indicates success:

You can view the → monitoring data on the monitoring mysql latest data page:
