Zabbix Monitoring Nginx Connection Status

Zabbix Study notes: Zabbix monitoring Nginx Connection Status

Zabbix monitoring Nginx

Zabbix can monitor the status of Nginx, about the status of a service can see the status of the service itself (version number, whether Open), but also should focus on service capabilities (such as the load effect of Nginx: number of connections , number of requests and handle number ). Below we use Zabbix to monitor nginx.

Installation of Nginx

If you want to view Nginx service status, the –with-http_stub_status_module module should be selected when installing the Nginx source code.

1. Unpack the installation package :

[Email protected] mnt]# tar xvf nginx-1.6.2.tar.gz

2. Configure the module in the installation directory :

3. options for installing the configuration :

Manually collecting Nginx data

After installation, in the Nginx installation directory (the default is /usr/local/nginx) We need to modify the Nginx main configuration file, if Nginx can support the display of status information can be viewed in Nginx version:

1. See if the module is installed successfully:
650) this.width=650; "src=" http://img.blog.csdn.net/20151230161054837 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

You can see that you already have the –with-http_stub_status_module module.

2. Modify the configuration file /usr/loca/nginx/conf/nginx.confto add the specified Server service in the HTTP section:
650) this.width=650; "src=" http://img.blog.csdn.net/20151230161353329 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

Note: Configure only allow 192.168.1.0/24 network segment people to view nginx status, other network segments of people can not view.

3. After the modification is completed, the Nginx service is started and the /usr/local/nginx/sbin/nginx file can be set up in a soft link to the /usr/bin/ directory for convenient period:
650) this.width=650; "src=" http://img.blog.csdn.net/20151230161710985 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

4. Open Nginx Service:
650) this.width=650; "src=" http://img.blog.csdn.net/20151230161737126 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

5. Use the command to collect the status information of Nginx:
650) this.width=650; "src=" http://img.blog.csdn.net/20151230161848129 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

6. The above information includes read, write wait, and number of connections, requests, etc., we need to write script information to be collected separately. The script contents are as follows:

#get_nginx_status. Sh#nginx Information Acquisition Script #!/bin/bash# setting initialization information nginx_server= "192.168.1.108" nginx_url= "http://${nginx_ Server}/status "#设置采集信息的方式function  get_active {    curl -s ${nginx_url}  | grep  "Active"  | awk -F  ":"   ' {print $2} '}function get_ reading {    curl -s ${nginx_url} | grep  "reading"  |  awk -F  ":"   ' {print $2} '  | awk -F  " "   ' {print $1} ' }function get_writing {    curl -s ${nginx_url} | grep  "Writing"  | awk -F  ":"   ' {print $3} '  | awk -F  '   '   ' {print $1} '}function get_waiting {    curl -s ${nginx_url} |  grep  "Waiting"  | awk -F  ":"   ' {print $4} '  | awk -f   " "   ' {print $1} '}function get_accepts {    curl -s ${nginx_url} |  awk nr==3 | awk -f  " "   ' {print $1} '}function get_handled {     curl -s ${nginx_url} | awk nr==3 | awk -f   " "   ' {print $2} '}function get_requests {    curl -s  ${NGINX_URL} | awk NR==3 | awk -F  " "   ' {print $3} '}# Get the input parameter of the user to get the corresponding value case $1 in     active)           get_active         ;;     reading)          get_reading          ;;     writing)          get_writing              ;;     waiting)          get_waiting          ;;     accepts)          get_accepts           ;;     handled)          get_handled          ;;     requests)          get_requests              ;;     *)          echo  "usage: $0  {active | reading | writing | waiting | accepts |  Handled | requests} "esac1234567891011121314151617181920212223242526272829303132333435363738394041424344454647484950515253545556575859606162636465 

7. After completing the script and testing, you need to modify the /etc/zabbix/zabbix-agentd.conf file to add the corresponding userparameter:

650) this.width=650; "src=" http://img.blog.csdn.net/20151230230526530 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

8. Restart the Zabbix-agent service on the client:
650) this.width=650; "src=" http://img.blog.csdn.net/20151230230647591 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

9. Use the Zabbix_get command on the server side to test to see if the data can be obtained smoothly, if the operation can be performed, indicating that the acquisition status is normal:
650) this.width=650; "src=" http://img.blog.csdn.net/20151230231757954 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

We have randomly tested four data here and found it to be normal.

Monitoring items added to Zabbix items

If the data collection is not a problem, then you can add items to the Web console.

Let's take nginx.active for example, other similar operations:
650) this.width=650; "src=" http://img.blog.csdn.net/20151230232051916 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

You can see that the items you need are already generated, and these items are part of Nginx's application:
650) this.width=650; "src=" http://img.blog.csdn.net/20151230232514894 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

Generate graphs

We can visualize the service status of Nginx (generate the corresponding graphs):
650) this.width=650; "src=" http://img.blog.csdn.net/20151230232700831 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

Create screen to display multiple graphs:
650) this.width=650; "src=" http://img.blog.csdn.net/20151230232835771 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

The screens of the Nginx condition state that created the agent1.example.com node is complete:
650) this.width=650; "src=" http://img.blog.csdn.net/20151230233057780 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

You can see the accpets, requests, handled status of Nginx:
650) this.width=650; "src=" http://img.blog.csdn.net/20151230233144542 "alt=" here write a picture describing "title=" "style=" border:none; "/ >

Summary:

Using Zabbix is similar to the monitoring steps for a service:
1. First to obtain the status of the service manually;
2. Then write the script to get it automatically and then write to the agent's/etc/zabbix/zabbix-agentd.conf file
3. The monitoring server zabbix-server the relevant acquisition test, if successful, the Web interface for the monitoring of items and graphs.
