Open source monitoring system zabbix--Shanghai Branch application

Background:
     Shanghai branch of the original monitoring system WhatsUp, because the C disk is full, the Ministry of Science and Technology network personnel in the cleaning of the C-disk space, mistakenly whatsup database file deleted, resulting in whatsup unable to open, after the lack of upgraded database script files, resulting in the addition of monitoring equipment , prompting for a conflict in the database foreign key, so that data cannot be inserted. Since there is no original file, the WhatsUp is completely unusable. Therefore, a new system is needed instead, because the better monitoring software under Windows is to pay, so, choose Open Source and powerful enterprise-level open source monitoring software Zabbix.

Zabbix Introduction:
     First of all, first of all, to understand the monitoring system of the major components: Data acquisition-storage-data display-alarm mechanism.
     Second, Zabbix mainly by the server side (used to accept data from the agent and stored in the database), the agent side (for data collection), the WebUI end (for display), the proxy side (for distributed monitoring , the proxy server accepts the data and then centrally sends it to the server side);
     Third, the server side of Zabbix now only supports running on Unix-like systems, and the agent can run on the OS that is available on the market. Since all the configuration of Zabbix is basically done in the Web interface, the post Web server must be built first.

Zabbix Usage Environment (Shanghai Branch):
     Server: x3650m3
    raid type: RAID1
    os:centos6.5
    web Platform: lnmp


Zabbix monitoring configuration process:
    host (monitored devices)-- Item (Monitoring item)--trigger (trigger)--action (action after triggering the monitoring entry)--media type (alarm medium)--user (alarm to the person concerned)

Zabbix monitoring and monitoring effect show:

Note: Is the Zabbix menu and navigation, the following is the general information of monitoring: the monitoring device has 87, of which 4 is a problem, there are 249 monitoring items, there are 249 triggers, 4 of which are disabled, etc.

Note: Represents the monitoring of the host group, the following numbers indicate the number of devices in each group, if the fault-free background color is green, if there is a fault, according to the level of fault divided into * * *, orange, light red, crimson and so on.

Note: If the latest 20 failures, as well as the cause of the failure, the time of occurrence, and the duration of the failure, there are actions, such as e-mail or so on!

Note: The network topology map of the branch, OK indicates that this device can be good, where the line represents the connectivity between each of the two devices, green indicates that connectivity is normal, red indicates that it is not normal. The equipment, as well as the connectivity between the devices are automatically monitored, if there is a problem, the green OK will become red problem, the green connector will become Red connector, the following will give two contrast chart.

Note: Is the problem when the graphics state, because the three branches of the branch is not open, so I set it to "maintenance status", so that the alarm will not be sent.

Note: The device is all the normal state diagram!
