Aids significantly in the threat-hunting process and provides a score-based evaluation of user experience

There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies. The retrospective network analysis capability of Observer GigaStor has been beneficial. It's a pivotal feature for network performance solutions. However, I prefer to consider the entire solution suite - GigaStor, along with GigaFlow and Apex - for comprehensive network visibility and monitoring. So, I prefer to integrate all three solutions to provide the best visibility. They complement each other well, with Apex aggregating and correlating data from both GigaStor and GigaFlow to enhance environmental understanding and troubleshooting efficiency.

Unified monitoring has reduced outages and enables proactive fixes with automated remediation

My favorite best feature is the ability to manage complex hybrid environments from a single dashboard. Zabbix natively supports monitoring everything from Linux servers and Windows servers to network devices and cloud infrastructure. The view I rely on the most on a day-to-day basis is a custom dashboard combining the problem widget and graph widget. The problem widget gives me an immediate filtered snapshot of the active alerts across all our servers. I pair that with the graph widget, which allows me to track performance metrics and compare values over time, such as monitoring storage and capacity trends on our Synology appliance. Having all of this in a single pane of glass saves me from constantly digging through logs. I also rely heavily on custom dashboards that combine the problem widget and the top host widget. The problem widget gives me an immediate filtered list of any active alerts across the entire environment. I pair that with the top host widget, which instantly shows me which servers are consuming the highest resources. Having all of these related metrics side-by-side in a single view allows me to spot the issue and identify the exact server causing it without having to dig through separate tools. Zabbix has built-in machine learning for continuous anomaly detection and proactive trend prediction. It establishes a baseline by analyzing historical data, allowing it to forecast impending issues, such as predicting exactly when a system will run out of resources before critical thresholds are breached. From a governance and security perspective, it delivers enterprise-grade security by supporting full data encryption and integration with external secret vaults to protect sensitive credentials. From a governance perspective, it features detailed configuration change tracking and role-based user permissions, which allows administrators to secure different teams or tenants within a single environment. Regarding accuracy, Zabbix's proactive alerts are highly accurate and trustworthy, provided they are fed enough historical data to establish a solid baseline. Regarding reliability and output, the prediction outputs are extremely reliable because Zabbix relies on transparent statistical mathematics, such as standard deviation and weighted moving averages, rather than a closed black box AI model. The straightforward statistical approach allows administrators to forecast value reliability and predict exactly how much time they have before a system reaches a critical problem threshold.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The ability to capture packets. It is not only for monitoring. That is very important for a company that wants to keep an eye on the packets, the transactions, the flows..."

"It can help to write your rules, organize firewalls, your block, and also your protocols and IP address to come in or out of your network."

"If you have the opportunity, I would strongly encourage you to get it, because it makes the IT experience easier and more flexible, by providing the ability to see things in your networks like the directory packet label."

"Industry-leading line rates, packet-capture technology and data-mining capabilities are the most valuable features."

"I also have the ability to see an application's performance, to see what's going on, why a network is slow, why this program for this user is experiencing a delay or some network issue"

"It's able to capture packets and, after a long time, you can come and use that information; to check, to analyze - everything you would want to do. So it's very good and helpful if you want to protect your data. It is stored in a certain place where you can access it every time you want to analyze it."

"There are many valuable features, but understanding end-user response times stands out. It provides a score-based evaluation of user experience, helping customers quickly pinpoint whether issues originate from the network, server, client, or application. Additionally, it facilitates in-depth analysis of application dependencies."

"Enables us to go back in time to capture an issue and analyze it for a solution, and this after the fact analysis is key to overcoming the bump in the night issues."

More Observer GigaStor pros

"It can send messages to our ticketing system."

"It provides high scalability, alerting, notification, templating, and end-to-end security."

"The initial setup was pretty straightforward, we did not face any issues and it was up and running within a day."

"Zabbix is a good and very cost-effective product."

"The monitoring capabilities of the product are excellent."

"We are now more pro-active before an issue appears to our customer because all the layers are now converged by Zabbix monitoring."

"ZABBIX is an all-in-one monitoring solution and we don't need any other monitoring tool since we use ZABBIX."

"The basic setup is very easy."

More Zabbix pros

Cons

"There are some issues, in our environment that puts processing restraints on the Gigastor when turning on trending data to be sent to APEX."

"I would like to have more than 4TB of storage available in the portable version of this solution."

"Maybe the graphical user interface could be simplified to allow people to use it more easily. It's already good, but they can work more on it to make it even easier."

"Graphics need improvement. Because a lot of the information there you have to input first in some case to have full potential. It could be more automated."

"The interface is pretty complex, so for the average user, it takes a while to get up to speed with it. I would like it to be more user-friendly."

"GigaStor feeds into Apex. So, the area where there could be improvement would be in artificial intelligence. For example, the incorporation of more advanced machine learning or AI capabilities could enhance its functionality."

"The Observer Console UI is consistent and stable, but could use some updating to be more modern."

"Zabbix can use better documentation and support for troubleshooting."

"The networking monitor is not too easy to work with."

"I think the reporting part of Zabbix can be improved in terms of more user-friendly graphics to display the collected data. Many simple users who don't know how to use Zabbix properly might get confused by the reporting, although at the same time it is very versatile for my company."

"I had problems using Zabbix when working with SUSE Enterprise; many companies use SUSE."

"It's OK for me as is, but some frontend improvements would be nice."

"If you want to use all of the features then you have to pay a licensing fee."

"Outside of the normal standard monitoring, I would like to extend patching, importing patching, and supporting patching for Windows Servers."

"They should open an SSH session from the web interface."

More Zabbix cons

Pricing and Cost Advice

"It's quite expensive."

"It depends on the requirements you have. There are three types of license. There's the updates license, the work group license, and the workstation license."

"This is an open-source solution that can be used free of charge."

"It is freeware. We still use the free version of Zabbix."

"We purchased Zabbix for a good price, including support"

"My manager is very happy because it doesn't cost anything."

"We were searching for an open source solution and Zabbix fit the bill because it is free and open source under the GPL license."

"It is a true open-source solution, so there are no licensing costs."

"It’s free of cost."

"The product is an open source and free solution."
