Zabbix has been designed to scale from small environments with a few devices to large ones with thousands of monitored devices. There are Zabbix installations out there with over 100,000 devices monitored, showing that Zabbix is able to process more than 3,000,000 checks per minute using mid-range hardware and collecting gigabytes of historical data daily.
This level of scalability is possible through the use of intelligent and efficient algorithms, which take advantage of modern hardware and software modularity that allows the division of components in different servers, resulting in superior performance.
Have remote branch offices, data centers or client sites that should be monitored, but you want to keep connection and open port count as low as possible? No problem, Zabbix distributed monitoring will handle that.
In addition to the single, central server model, Zabbix also offers easy to set up and nearly maintenance-free distributed monitoring with Zabbix proxies. The proxy has been serving Zabbix users for many years now, and it is a very robust solution.
Zabbix proxy can help with monitoring large data centers efficiently, and it can also be run on embedded hardware for smaller environments. Preconfigure a Zabbix proxy, ship it to the remote location to be plugged in - and from then on manage all the proxy configuration from the central Zabbix server.
In addition to making the monitoring of remote locations easy, proxies also help greatly with scaling for large environments.
Besides the powerful agentless monitoring, Zabbix agent offers high performance for monitoring the operating system and application-specific metrics.
Zabbix agent uses minimal CPU resources and memory and is compatible with several platforms including Linux, UNIX and Windows.
Zabbix server and Zabbix proxy use various data caching solutions, giving them great performance and reducing the load on the backend database.
The networking communication protocols in use with Zabbix are extremely efficient with their use of computing resources and bandwidth of the network, even in large scale deployments.
A crucial requirement for a modern IT infrastracture is the support of High Availability for its Enterprise services and applications. All components of Zabbix are immune to network and communication outages by using efficient data buffer control.
In an enterprise environment there will be lots of aging systems that can not be easily replaced or upgraded. Forcing a monitoring agent upgrade only because the main monitoring system is upgraded is not acceptable - thus the latest and greatest Zabbix server supports all the previous agent versions back to the very first releases, dating more than 10 years ago.
Zabbix upgrading in the bounds of one major version is very easy and does not require any changes to the backend database. Upgrading from one major version to another is fully supported and procedures for proper database upgrade are supplied.
You can forget about changing multitude of configuration files and restarting services after that - almost all aspects of Zabbix are controlled through a safe and simple web interface. Of course, for more advanced operations, API is available.
Creating backups of all the configuration data and collected values is simple and can be done with standard tools and procedures - after all, everything is stored in a database.
Access to the Zabbix frontend can be done through an SSL protected connection, ensuring security between users and server. In addition, the frontend has a self-protection against brute force attacks.
All components of Zabbix can run as unprivileged users - which is especially important for the native agents. Even more, running Zabbix daemons under a privileged account requires extra steps. The components communicate with each other and only accept connections from authorized IP addresses, other connections are automatically rejected.
With encryption support it is possible to secure communications between separate Zabbix components (such as Zabbix server, proxies, agents and command-line utilities) using Transport Layer Security (TLS) protocol v.1.2. Certificate-based and pre-shared key-based encryption is supported. Encryption is optional and configurable for individual components.
Zabbix API offers unprecedented flexibility to perform two-way integration with enterprise applications easily. Automation can be done by scripts in various languages like Ruby, Python, Perl, PHP, Java or shell scripts. Integrate with standard system management tools like Puppet, cfengine, Chef, bcfg2 and others, or make Zabbix configuration automatically updated from your inhouse management tools.
For the Zabbix frontend, authenticate user logins against a central authority like LDAP (including Microsoft Active Directory) or Radius, allowing them to use the same password for monitoring system as everywhere else, or even automatically gaining proper permissions using SSO (Single Sign On).
With IPv4 segments running out quite rapidly, larger ISPs are more and more looking into IPv6.
All Zabbix components support both IPv4 and IPv6, allowing for use in a mixed environment or pure IPv6 environment.
“Scaling in Zabbix works quite well: with proper tuning, it can withstand 6000 knots. The openness of the source code provides freedom and security.”
“Really robust server processes, light weight agents and infinite customization options. Mature code.”
“It's a robust monitoring software and very intuitive. The deploy is faster than other monitoring software and have a lot of complements for cover a wide variety of software, hardware, services that are currently used in the market and that grows daily.”
“The new Zabbix 4.0 has significantly enhanced the dashboard and other graphical widget.”
“For monitoring your large system Zabbix can be your first choice.”
“We mоnіtоr servers wіth the аgent, SNMP devісes, JMX endроіnts аnd REST web APIs. We nоw nо lоnger hаve tо раy fоr оur mоnіtоrіng sоlutіоn.”
“We use Zabbix organization-wide to monitor several environments in AWS.”
“I would say that Zabbix is an open source monitoring software tool for various IT components, including networks, servers, virtual machines and cloud services. That it is a tool of great quality and with great security.”
“For me zabbix is the most complete software for network monitoring in the free and pay version.”
“Zabbix is helping in to monitor the Application and Network. The best thing I like in it is the flexible dashboard which can be configure according to the need of the administrator.”
“Zabbix is a fascinating robust tool for monitoring and correlation events, this is the proper solution for networks and applications. Zabbix will save much of your time and effort. This product is very wonderful to create your monitoring tool cheaply and safely.”
“Zabbix is a system that allows you to conduct a comprehensive monitoring of servers, network devices and virtual machines, analyze the load and productivity of equipment.”
“Zabbix offers brilliant visualization and informing capabilities based on the collected data. That’s why Zabbix can be considered an ideal tool for scaling and modeling”
“Very good supplier, always answers with great agility, objective and ready to solve the problems encountered with the tool.”
“Installing and implementing zabbix is very easy, with a minimum of knowledge you can do it. We use zabbix to monitor cellular networks and servers, so far it has been very stable.”
“We use the program for monitoring cellular networks, so far it has been very stable for us.”
“Zabbix is a network monitoring tool that allows us to monitor the performance and availability of all services from applications involved in the network, to the numerous equipment that are interconnected to it, such as servers, hosts, switches, routers and many others.”
“Small and big telecommunications companies should use Zabbix as their main solution for monitoring no doubt.”
“1. Eхсellent fleхіbіlіty аnd соnfіgurаbіlіty оf the system. 2. Crоss-рlаtfоrm! The аbіlіty tо mоnіtоr аll аvаіlаble орerаtіng systems. 3. Gооd dосumentаtіоn. 4. The орen sоurсe соde!”
“We are using Zabbix for more than 10 years and we are very happy.”
