Several common network/server monitoring open source software

Want to get a clearer picture of your network? There's no better use than these free tools.

Network and system monitoring is a broad category. There are solutions for monitoring servers, network devices, applications that work properly, and for tracking these systems and equipment performance and providing trending performance analysis. Some tools, like an alarm clock, call the police when a problem is found, and some other tools can trigger actions even when the alarm is ringing. Here, a number of open source tools have been collected to address some or even most of these issues.

Cacti

Cacti is a wide range of charts and trend analysis tools that can be used to track and almost draw out any indicators that can be monitored to depict charts. From the utilization of the hard disk to the speed of the fan, in a Computer management system, as long as the indicators can be monitored, cacti can be monitored and quickly converted into visual charts.

Nagios

Nagios is a classic veteran system and network monitoring tool. It is fast, reliable and needs to be customized for the application. Nagios is a challenge for beginners. But its extremely complex configuration is just as powerful as it can be for almost any monitoring task. The disadvantage is not engaging, but its strong function and reliability make up for this shortcoming.

Icinga

Icinga is a reconstructed Nagios branch that provides a comprehensive monitoring and alerting framework dedicated to the design of an open and extensible platform like Nagios. But it has a different web interface than Nagios. Icinga 1 is very similar to Nagios, but Icinga 2 is rewritten. Two versions are well-compatible, and Nagios users can easily go to the Icinga 1 platform.

Nedi

Nedi may not be as famous around the world as other tools, but it is a powerful solution for tracking network access. It runs the network infrastructure and equipment catalog smoothly, keeping track of any events. And can provide the current location of any device, also including the historical location.

Nedi can be used to locate stolen or lost devices as long as the device appears on the network. It can even display all the discovered nodes on the map. And it is clear to tell people how the network is interconnected to physical device ports.

Observium

Observium combines system and network monitoring to perform well in performance trend monitoring, which supports static and dynamic discovery to confirm servers and network equipment, and uses a variety of monitoring methods to monitor any available metrics. The web interface is very neat and easy to use.

As we have seen, Observium can also show the actual location of any monitored node on the map. It is important to note the count of active devices and alarms on the panel.

Zabbix

Zabbix uses a range of tools to monitor servers and networks. Zabbix's monitoring agent supports most operating systems, and you can either passively or use external checks, including SNMP, to monitor hosts and network devices. You will also find a lot of reminders and notification facilities, and a very user-friendly web interface for different panels, in addition, Zabbix has some special management tools to monitor Web applications and virtualization management programs.

Zabbix can also provide a detailed interconnect graph so that we know how certain objects are connected. These graphs can be customized, and the diagram can also be created in the form of a cluster of servers and hosts being monitored.

This article introduces 6 practical open-source monitoring tools, not only can monitor your network resources, but also can monitor the server, user requests, website performance, to provide you with a comprehensive, one-stop guide to the site.

1. Munin

Munin is an open Source network resource monitoring tool that analyzes resource trends and "What just makes performance dead". Monitor core system resources, including memory, disk, CPU usage, server applications such as MySQL, Apache, and squid. It is easy to use, is a plug-and-play tool, and offers many rich charts.

Munin is a tool that collects and graphically data from the client-server architecture. Munin allows you to track the running records of hosts, called nodes, and then send them to a central server, which can then be displayed as images.

Currently, the latest version of Munin is Munin 2.0.11.1, which you can download from GitHub or sourceforge.

2.Pingdom

Pingdom is a well-known surveillance service provider founded by Sam Nurmi, and Sam Nurmi was the CEO of Loopia, the largest web hosting company in Sweden.

Using Pingdom, you can monitor websites and servers in multiple places on the Internet to make sure they are working properly. In addition to providing Web page loading speed, DNS, ping and routing, FTP server, e-mail and other checks, also provides online time monitoring. Pingdom inspection and monitoring is also free of charge. As long as the registration can enjoy the free version of monitoring, The disadvantage is only 1 stations to monitor.

3.Graphite

Graphite is an enterprise-class monitoring tool, written in Python, using the Django framework. Originally developed as a support project by Chris Davis when he was working in Orbitz, he eventually became a basic monitoring tool.

Graphite can be used to collect all the timely status of the server, user request information, memcached hit rate, status of the RABBITMQ messaging server, and load status of the UNIX operating system. The graphite server needs to be updated approximately 4,800 times per minute, with simple text protocols and powerful drawing capabilities that can be easily extended to any system that needs to be monitored.

Graphite the data in a graphical form. It does two things: Storing time-series data, and graphics that present the data as needed. At present, the latest version of graphite is 0.9.10, the source is hosted on the launchpad.net.

4.Ganglia

Ganglia is an open-source cluster monitoring project initiated by UC (University of California), ganglia is a distributed monitoring system based on a scalable, high-performance computing platform. It has been extensively ported to various operating systems and processor architectures and is currently being used in thousands of clusters around the world.

Ganglia Web version 3.5.7 has been published and hosted on SourceForge. The core of ganglia includes Gmond, Gmetad, and a web front end.

Ganglia is mainly used to monitor the performance of the system, such as: CPU, memory, hard disk utilization, I/O load, network traffic, etc., through the curve is easy to see the working state of each node, the reasonable adjustment, distribution system resources, improve the overall performance of the system play an important role.

5.Nagios

Nagios, formerly known as Netsaint, was developed and maintained by Ethan Galstad. Nagios is an enterprise-class monitoring system that effectively monitors the host status of Windows, Linux, and Unix, as well as network settings such as switch routers, printers, and more.

Nagios is the most important feature of the system or service status is abnormal when the mail or SMS alarm, the first time to notify the site operators, in the state after the resumption of normal mail or SMS notification.

6.collectd

COLLECTD is an open-source performance monitoring tool developed in C that requires no system cron support and is easy to use. COLLECTD is a plug-in architecture, mainly divided into input, output type plug-in.

When the system runs and stores information, COLLECTD periodically counts system-related information. That information can be used to find current system performance bottlenecks. Compared to other monitoring tools, COLLECTD is written entirely in C, with high performance and portability, allowing it to run on systems without scripting language support or cron daemon, such as embedded systems. At the same time, it contains new features that optimize and process hundreds of thousands of datasets.

COLLECTD contains more than 70 plug-ins, while COLLECTD offers powerful network networking features that can be augmented in a variety of ways.

However, the COLLECTD is not able to generate images directly. Although it can write an rrd file, it cannot generate graphics from these files. Currently the latest version of COLLECTD is 5.2.1, the source is hosted on GitHub.

Most of these products are open source, for small and medium-sized companies, the use of open source products can greatly improve the team's development efficiency. And these products have a very active community, after encountering problems can be well resolved.
