Python uses Nagios to add WeChat alarm notification function

Nagios is an open source free network monitoring tool that can effectively monitor the host status of Windows, Linux and Unix, network settings such as switches and routers, printers, etc. When the system or service status is abnormal, an email or SMS alarm will be sent to notify the website operation and maintenance personnel immediately, and a normal email or SMS notification will be sent out after the status is restored.

Nagios calls the API interface of the WeChat public platform to send alarm emails. Before the official operation, there are several preparations to be done. First install nagios, you can use the nagios one-click installation script I provided. Then I went to the WeChat public platform to apply for an enterprise account. When I applied, I filled in the name of organization. It can be used without certification. Finally, log in to the public platform to add an address book, and create a new application (such as nagios). Record the application ID for later use. User permissions are set by yourself.

WeChat script

After nagios and WeChat platform are ready, download the WeChat command script. Right-click Download and save. Then upload it to the nagios server, such as the /usr/local/nagios/python/weixin directory, and set the file permissions to executable. Create a new config.py file in the /usr/local/nagios/python/weixin directory and add the following configuration.

#coding:utf-8
CorpID='xxxxx'
Secret='xxxxxxxxxxxxxxxxx'
DEBUG=0
ToUser='sijitao.net'
AgentId=1

CorpID and Secret can be obtained by logging into the WeChat public platform and opening the added application (such as nagios).

The parameters passed by the WeChat script command are separated by the "-@@-" symbol. For detailed instructions, please refer to my github address: https://github.com/zhangnq/nagios/tree/master/weixin

Nagios configuration

The following is the general configuration on nagios.

Add the weixin command to the commands.cfg command file:

define command{
command_name notify-host-by-weixin
command_line /usr/local/nagios/python/weixin/NotifyByWeixin.py "host-@@-$NOTIFICATIONTYPE$-@@-$HOSTNAME$-@@-$HOSTSTATE$-@@-$HOSTADDRESS$-@@-$HOSTOUTPUT$-@@-$CONTACTALIAS$"
}
define command{
command_name notify-service-by-weixin
command_line /usr/local/nagios/python/weixin/NotifyByWeixin.py "service-@@-$NOTIFICATIONTYPE$-@@-$SERVICEDESC$-@@-$HOSTALIAS$-@@-$HOSTADDRESS$-@@-$SERVICESTATE$-@@-$SERVICEOUTPUT$-@@-$CONTACTALIAS$"
}

Add the contact template to the templates.cfg template file:

define contact{
name weixin-contact
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r,f,s
host_notification_options d,u,r,f,s
service_notification_commands notify-service-by-weixin
host_notification_commands notify-host-by-weixin
register 0
}

contacts.cfg Add a WeChat notification contact to the contacts. The alias name here must be the same as the name account in the WeChat public platform address book before it can be sent successfully.

define contact{
contact_name zhangnq-weixin
use weixin-contact
alias zhangnq
email admin@sijitao.net
}

Finally, after adding the contact zhangnq-weixin when configuring the service, you can send alarm emails through WeChat.

This is all about the Python function that the editor shared with you about using Nagios to add WeChat alarm notifications. I hope it will be helpful to you.
