For the daily work of operation and maintenance, server monitoring is a must and the most basic content. In the process of enterprise network operation and maintenance, the administrator keeps an eye on the server and network operation status at any time, so as to find problems in time and reduce the occurrence of failures as much as possible. When there are many devices and servers in the network, in order to obtain various monitoring information more conveniently and quickly, some centralized monitoring software is usually used.
There are three types of server monitoring software currently in use: zabbix, cacti, and nagios . Let me briefly introduce these three software.
zabbix
Zabbix is an enterprise-level open source solution that provides distributed system monitoring and network monitoring functions based on the WEB interface.
Zabbix can monitor various network parameters to ensure the safe operation of the server system; and provide a flexible notification mechanism to allow system administrators to quickly locate/solve various problems.
cacti
Cacti is a set of graphical analysis tools for network traffic monitoring developed based on PHP, MySQL, SNMP and RRDTool.
nagios
Nagios is an open source free network monitoring tool that can effectively monitor the status of Windows, Linux and Unix, network devices such as switches and routers, printers, etc. When the system or service status is abnormal, an email or SMS alarm is sent to notify the website operation and maintenance personnel at the first time, and a normal email or SMS notification is sent after the status is restored.
However, for most novices, although these three monitoring software have powerful monitoring functions, they are not easy to use, and installation and deployment are difficult.
The function of resource monitoring in operation and maintenance work is to find problems, so that operation and maintenance personnel can deal with and solve problems in a timely manner. Based on this, novices in operation and maintenance should find a software that is more suitable for them, simple to operate and easy to use, and at the same time satisfies the monitoring function .
After comparing other monitoring software, I finally found a good monitoring tool, which cannot be said to be a monitoring tool, but should be the monitoring function of the operation and maintenance panel.
This operation and maintenance panel is called Cloud Helper (official website), compatible with linux/windows, compatible with all cloud vendors, and has relatively few restrictions on servers. At the same time, although its server resource monitoring function is relatively basic, it is quite complete.
After adding a server (by the way, the way they add a server is very simple, the probe is installed, and you can directly log in to this software) and then you can see the real-time monitoring overview of the CPU, memory, disk, and network in the resource monitoring module.
You can also click to view the usage of each resource
The most important thing is that you can set alarms. Once a certain resource triggers the alarm rules you set, an alarm notification will be sent, which is very convenient. You can deal with problems in a timely manner without real-time monitoring of resource data.
Of course, this software is essentially a server management panel, resource monitoring is only one of its functions, and there are other basic operation and maintenance functions such as one-click security inspection, one-click repair, environment deployment, and site management.
