Monitoring ease and cost-saving benefits enhance operational efficiency

The monitoring in OP5 Monitor is very easy because we can directly use custom plugins. We can write custom scripts and use those scripts directly. It's very low cost, open, and the dashboards are easy to see. We can extract the reports easily, and this is very easy to compare. Real-time monitoring in OP5 Monitor provides data every one minute or every five minutes, enabling us to get live data from the last one minute or last five minutes. OP5 Monitor gave us proper server availability, so we can always check whether a server goes down or the server CPU and memory decreases. Before reaching a particular bottleneck situation, we identified and fixed the issue, which helped us from a cost-saving business perspective. It helped us avoid application downtime.

Helps reduce response time but has room to improve customization complexity

We are not working on simple standalone solutions like Kaspersky DDoS Protection or Hybrid Cloud Security. Once you understand Zabbix, then it is easy to customize those web pages and graphs for our customer use. It is fully automated to your requirements. Zabbix is working fine with no issues, and I am satisfied with it. We have combined Zabbix and SolarWinds. The integration works fine, and it is easy to integrate Zabbix with the IT environment. We were trying to purchase MDR (Managed Detection and Response), but we are not working on that. I don't have real experience with MDR. We are using Falcon software for that. We are working with Falcon Complete, not with Sandbox. We are not using Kaspersky for business or cloud protection. For that, we are using Zabbix CrowdStrike Falcon Complete solution. I have given this review an overall rating of 8.

Quotes from Members

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

Pros

"The best feature is that it is very relatable, stable, and scalable. The logger is a part of the software, but it's not the most important point of it."

"The API makes it pretty easy to integrate with any system."

"Instead of checking the logs each Monday, or checking that applications are running, and checking your ticketing system for angry users, you put this system in place and it monitors and continuously tests everything that is of importance to you and your users."

"Especially with the API, where I can use the data with many other systems, it's great."

"The monitoring in OP5 Monitor is very easy because we can directly use custom plugins; we can write custom scripts and use those scripts directly, it's very low cost, open, and the dashboards are easy to see."

"It monitors and continuously tests everything that is of importance to you and your users. It could be everything from monitoring disk space to CPU usage to memory. It could include determining if the response time in your e-commerce platform is quick enough, or whether you have too many bounces from some of the pages on your website. You want to monitor anything that could cost you money or time or resources. You can do that with this system. It's very flexible."

"Its open-source environment is accessible to everyone."

"With limited hardware or a virtual machine, you can address a huge network, hundreds of thousands of elements that need to be monitored. Other commercial software is not on that level."

More OP5 Monitor pros

"It is a very good product, and it is for a good reason that we have chosen Zabbix as part of our monitoring portfolio."

"If you are serious about your infrastructure then you have to know what is going on, and with Zabbix we know when servers are using too much CPU, memory, disk IO, etc., and besides getting notified when something goes wrong, we are also now aware of how well our infrastructure scales, something that can save us money and frustrations."

"The most valuable features in Zabbix are those that help us overcome bottlenecks in CPU usage, as well as reduce memory delay. I know that we have only reached the tip of the iceberg of what Zabbix's features can do for us, and we have not used all of them yet."

"For internal monitoring and network monitoring the solution is really good."

"I like being able to use proxy servers for different locations. The agents are pretty cool. They're easy to roll out. The standard out-of-the-box templates are also pretty easy to use. The integration with other learning products is also good. I have, in the past, used Slack, but we've integrated it with Microsoft Teams. We also use it for SMS with a service called Redcoat. It is very flexible. It does what I need it to do, and my manager is very happy because it doesn't cost anything. We are nearing 4,000 hosts inside Zabbix, and we've got another 6,000 access points to add to it. We've thrown everything at it, and it has managed to keep going. I am very impressed with the tool, and I'd shake their hand very hard if I got to say the compliments to the Zabbix team. They keep improving it and doing refreshes, which is one good thing about it. There is also online information as well as books that you can purchase if you're willing to read enough. There is a lot to pick up, but it is a pretty complete solution."

"This is a stable product."

"This solution is very good for data reporting."

"One of the real benefits is the API; you can do anything with an API, it makes life much easier."

More Zabbix pros

Cons

"OP5 Monitor could include application monitoring in addition to infrastructure monitoring. If application business transactions were monitored, it would be helpful."

"We do not get performance reports properly, which needs improvement."

"IT environments today are in constant flux. This is driven by the newer cloud technologies such as Kubernetes and Docker, etc. The whole Nagios-based monitoring system that OP5 is created on top of, is based on a host-service model. There is a need for a strategy on what to do with more dynamic environments. There is some cool stuff going on in that direction."

"OP5 lacks some visualization, a feature that makes some other products nice. Op5 is built for purpose, which is fine, but if you compare it with some new products, the visualization is not so appealing, especially for management... If you don't need fancy visualizations, OP5 is fine."

"The solution is useful for tweaking. However, there have been some negative experiences, such as limited report capabilities. The only report available is in PDF format, making it difficult for teams managing multiple servers to extract data in Excel format. The speaker recommends that the team improve the report capabilities to better serve users."

"The user interface is not what we are used to these days, and should be improved."

"They need to improve the dashboard interface."

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

"Having a more customizable interface and dashboard would be an improvement."

"In the next release, I'm hoping for features targeted towards larger users with more customizable options. Despite this, I think pre-canned reports that can be used straight out of the box would be beneficial rather than having to configure each report individually. Additionally, a deeper dive into software configurations on the machines would be useful, although I understand there may be challenges in implementing this due to scripting requirements. More documentation would also be appreciated."

"It's open-source software, and due to that, they really don't have legacy service monitorings like APM, or build-on capabilities, and the pure part of the transaction-related data."

"The low discovery functionality is still very young so this feature has a lot of room for improvement."

"The user interface could be a bit better. They could update it a bit."

"I really do not like this solution, almost all of its features are awful."

"The UI is hard to get used to."

Pricing and Cost Advice

"OP5 has a very low price as a solution, compared to many other solutions out there."

"It was not expensive. And because it's less demanding in terms of hardware, you don't have to pay for another SQL or other database license, and you can have a huge installation on one machine..."

"The cost of the license and support are separate. If you want platinum call support, it will cost more than a regular call. I did not opt for it, as it is an additional cost."

"This solution is completely open-source, so it is quite affordable."

"Zabbix and Grafana are both open source products, we only needed to go to their website and download the application and we began to use them. The solutions are free."

"It is free, which allows us to reduce costs."

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

"We’re using the free version, which covers all our current needs."

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

"It is worth every cent to pay or even study to do your own installation."

"Its licensing is fair. It seems to be much cheaper than others."
