1, zabbix overview
Zabbix is an enterprise class distributed open source monitoring solution.
Zabbix software can monitor the health and integrity of many network parameters and servers. Zabbix uses a flexible alarm mechanism that allows users to configure email based alarms for almost any event. This allows users to respond quickly to server problems. Zabbix provides excellent reporting and data visualization based on stored data. These features make Zabbix an ideal choice for capacity planning.
Zabbix supports active polling and passive capture (trapping). All Zabbix reports, statistics and configuration parameters can be accessed through the Web-based front-end page. The Web-based front-end page ensures that you can access the network status and server health you monitor anywhere. After proper configuration, Zabbix can play an important role in monitoring the IT infrastructure. Whether for a small number of users The same applies to small organizations with servers or large enterprises with a large number of servers.
2, zabbix function
zabbix distributed system monitoring
Zabbix is a highly mature and perfect network monitoring solution. A software package contains a variety of functions.
data acquisition
Availability and performance inspection;
Support SNMP (including active polling and passive capture), IPMI, JMX and VMware monitoring;
Custom check;
Collect the required data according to the user-defined time interval;
Perform data collection through Server/Proxy and Agents.
Flexible threshold definition
You can refer to the backend database to define a very flexible alarm threshold, that is, trigger
Highly configurable alarms
You can send alarm notification according to the increment plan, receiver and media type;
Using macro variables can make alarm notification more efficient and useful;
Automatic operations include remote execution commands.
Real time graphics
Using the built-in graphics function, the monitoring items can be drawn into graphics in real time.
Web monitoring function
Zabbix can track the click operation of the simulated mouse on the Web site to check the function and response time of the Web site.
