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

"OP5 Monitor is a great choice due to its being built on an open-source monitoring tool and provides ample opportunity for customization based on specific support requirements. It is also user-friendly and easy to manage with a wide range of plugins available for use. In comparison to other enterprise tools, such as Micro Focus, OP5 Monitor stands out for its features and cost-effectiveness, making it the best tool in the market. Customization is one of the key strengths of the tool and provides a lot of capabilities. Additionally, it is easy to find support and plugins for the tool through online resources."

"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."

"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."

"We can also observe whatever we want, and there are no limitations."

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

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

"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

"The solution allows you to configure and customize how you want to collect information from servers or other systems."

"Setup was straightforward. Initial deployment took two or three months."

"It's the best solution. Great. I would rate the overall solution ten out of ten."

"The solution is quite mature and very stable."

"The most valuable feature is network traffic monitoring."

"Health and communication links availability."

"With Zabbix, you receive a free enterprise-class monitoring solution, as long as you know how to use it."

"The initial setup, while not simple, is easier than other products."

More Zabbix pros

Cons

"They need to improve the dashboard interface."

"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."

"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."

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

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

"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."

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

"The reporting features need improvement, especially detailed inventory reporting. Since it's freeware, reporting may not be a major focus."

"Reporting is weak, if you want something better you must write your own SQL scripts."

"I wish it had more options for personalizing the product, such as being able to include your company's logo without editing text files."

"The APM monitoring has room for improvement, although I hear that the new 5.2 version has some improvements in that area, and I'd like to give that a go."

"Zabbix technical support is sold separately."

"It should be easy to modify the front end."

"Even though it’s such a powerful monitoring system, it would be more helpful if it had a flexible UI."

"It becomes complex when we are growing and need to add proxies. We need more scalability features and documentation for different use cases."

More Zabbix cons

Pricing and Cost Advice

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

"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."

"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..."

"Zabbix is open-source so if one wishes to implement it in-house, they must have qualified professionals to set up and optimize databases, Linux/Unix OS, PHP, Apache, and depending on what is monitored, a full-stack network and systems administrator may be needed."

"If you have 20,000 hosts, the support costs around €95,000 for a year."

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

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

"It's free software released under the GNU/GPL license."

"It is reasonable."

"Zabbix is a free solution but the support contact costs money."

"The tool's licensing costs are yearly."
