Alerting precision has reduced incident response times and improved department-level network visibility

The auto-pause sensor during the maintenance window is good without any false alerts, and it prevents me from getting flooded with alerts during planned maintenance, helping department heads understand their own network usage better. It has reduced incident response time by giving clearer ownership of each alert, ensuring alerts go to the proper recipient. SNMP testers and auto-pause are among the best features of PRTG Network Monitor, which is particularly useful for different departments such as HR and finance, where alerts can be filtered accordingly. The alerting features and dashboard of PRTG Network Monitor are very helpful, especially in our industry. However, the dashboard can look cluttered on smaller screens, which is one negative aspect. PRTG Network Monitor has impacted us positively; we have stopped getting flooded with alerts during planned maintenance or unplanned outages. Compared to others, this gives specific alerts very quickly and helps department heads understand their own network usage better, thus reducing incident response time so that each alert has clear ownership.

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.

Generates close to real-time alerts so users can resolve issues, but needs more integration and public cloud monitoring features

ClaudiaChen

Cloud Architect - Senior Technology Architect at Telstra

As Zenoss Service Dynamics is more for network-centric devices and you want to monitor, for example, a server, its services, IP addresses, and interfaces, if it's a network and you're going to monitor multiple items, you'll be charged multiple times. This is what Zenoss Service Dynamics needs to improve to make sure that customers pay just one fee to monitor the entire server. What I'd like to see in Zenoss Service Dynamics in the future is a public cloud monitoring feature, particularly for the Azure public cloud. Another additional feature I'd like to see in the next release of the solution is integration with the Azure public cloud because I know that there are some services from Azure that Zenoss Service Dynamics is currently unable to monitor.

Quotes from Members

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

Pros

"The initial setup is pretty easy."

"The remote probes are very useful. They allow us to provide a reference across different areas in the network. In trying to localize issues, that's very useful."

"PRTG Network Monitor helped us detect the failing RAID controller before it completely collapsed, allowing us to avoid potential data loss."

"It is easy when it comes to dependencies of devices, so if your router goes down, the three or four switches behind it will automatically be paused so that you don't get multiple alerts."

"I think net flow is PRTG's most valuable feature because it doesn't cost much for us because the net flow sensor is already included in the PRTG license. We can monitor our traffic in our proxy and router."

"PRTG Network Monitor has positively impacted my organization as we are not seeing any critical issues or major impacts for our applications, our servers, and our networks nowadays."

"The authentication links into our standard Active Directory authentication, which is very good."

"It allows us to directly add individual VMs independently."

"We use Zabbix to monitor our organization's IT infrastructure and workstations. We don't use Microsoft Intune since it's expensive. The tool's real-time alerting system has proved crucial for us, particularly when a new device joins a network that is not one of our own devices. It notifies us about the presence of this new device, allowing us to investigate further. Additionally, it alerts us about disk usage, memory usage, and the software installed on the machine."

"In terms of customization and integration, we have more flexibility. We can automate configurations, define deletion rules, and customize based on the needs. The client interface allows for further configuration, making it quite comprehensive."

"The initial setup was not complex."

"The level of discovery-based configuration that lets us auto-configure the monitoring for various systems is a valuable feature."

"We use it to monitor and manage our servers."

"The solution is open-source, easy to manage, and user-friendly making it easy for anyone to use."

"Zabbix is very easy to implement."

"The product is very stable."

More Zabbix pros

"The custom built integration is one of the most valuable features because you can see all the especially critical items."

"They have also accommodated many state-of-the-art technologies like Docker and ZooKeeper."

"The most valuable feature is the flexible discovery mechanism."

"It's easy to use."

"Its Docker Container concept is mind blowing. It is the first monitoring tool which comes with Docker features."

"What I like most about Zenoss Service Dynamics is that it monitors the devices and gives close to real-time alerts. For example, in case the device is not available, Zenoss Service Dynamics generates an alert so my team can resolve the issue."

"The product offers good documentation that helps with initial training."

Cons

"We need something that is more predictive. We would prefer if it wasn't a solution that was corrective and instead offered predictive insights so that we can handle problems before they even occur."

"PRTG Network Monitor needs to enhance network performance monitoring."

"Having a Unix implementation or Unix installation could be an improvement. Right now, it's based just on Windows, and that's a problem for some customers."

"There are some vendor-specific sensors in PRTG Network Monitor, particularly for older hardware, that don't always provide consistent results."

"They need to address the slowness issue that sometimes occurs with PRTG Network Monitor."

"When it comes to third-party integration, one of the things we were looking at was putting some sensors onto our firewall, for instance. If there were a little bit more documentation and some step-by-step guides around that, that would be useful for us."

"I would like to see Office 365 monitoring. Essentially, it doesn't do it. I assumed not at all, but apparently it does it slightly. However, due to issues with APIs, they currently don't provide full monitoring for O365."

"They should work on syncing the solution with Gmail."

More PRTG Network Monitor cons

"Implementation is always tailored to the customer and the kind of information we need from the client to carry it out can make them very uncomfortable. Sometimes the clients are not ready to share it."

"The only issue I can note is that it's Linux-based, and Linux documentation is not the best."

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

"Documentation terminology could be improved."

"Sometimes, the documentation is a little bit written in Estonia – a country in Europe. The language barrier and translation to English can sometimes make it difficult to understand what they're trying to get at. It's just a language thing."

"It would be helpful if they translated the documentation to Cyrillic languages."

"Zabbix is powerful, but it is difficult to understand initially. There are many things that can be improved, but we might not be using Zabbix to its fullest extent. The software has more features than we need."

"There are a lot of areas for improvement, specifically in the dashboards and reports functionalities."

More Zabbix cons

"Now it is stable, but they should design threshold parameters in percentage instead of raw values."

"There is room for improvement with the administrative part. They introduced Control Center to manage things in Zenoss 5. The services that Zenoss provides remained the same, but the administrative part, since they introduced Docker, etc., has become a little complex"

"As Zenoss Service Dynamics is more for network-centric devices and you want to monitor, for example, a server, its services, IP addresses, and interfaces, if it's a network and you're going to monitor multiple items, you'll be charged multiple times. This is what Zenoss Service Dynamics needs to improve to make sure that customers pay just one fee to monitor the entire server. What I'd like to see in Zenoss Service Dynamics in the future is a public cloud monitoring feature, particularly for the Azure public cloud. Another additional feature I'd like to see in the next release of the solution is integration with the Azure public cloud because I know that there are some services from Azure that Zenoss Service Dynamics is currently unable to monitor."

"The AI aspect needs to improve."

"It would be ideal if the product offered sound alerts."

"There was a problem with Zenoss and storage monitoring."

"The inclusion of a feature to show a graphical view of the network would be a helpful improvement."

Pricing and Cost Advice

"It is expensive."

"Right now, the smallest sensor pack that they have is just a bit out of range for me, as a business. This kills me, as I need the product. Therefore, there is always a balance between needing to buy it or continuing their free version."

"The pricing is very low compared to other solutions."

"Pricing for PRTG Network Monitor is a nine out of ten. It meets my company's budget and monitoring requirements. My company is on a perpetual license."

"On a yearly basis, I believe it's between £1,200 and £1,500."

"One thing I like is that when you buy sensors, it's a perpetual license, so once you buy 2,000 sensors, you've got 2,000 sensors; it's not a recurring cost."

"In my company now, we are using the free version."

"We bought a license for 4000 sensors."

More PRTG Network Monitor pricing and cost advice

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

"For pricing, it's free. We don't pay anything for it. They open-source the code, and people pay for support."

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

"The solution is free. However, many open-sourced tools start out free but eventually start charging."

"This solution is open-source and free to use."

"There is a license required for this solution and we pay annually for our license."

"The tool's licensing is good."

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

More Zabbix pricing and cost advice

"The pricing depends on the environment, the number of services, and the size of the data center. It can go from $100,000 to a million dollars."

"There are additional costs you'll have to pay apart from the license fee for Zenoss Service Dynamics. I can't remember exactly how much my company is paying because I don't handle the finance part, but the cost is paid annually. On a scale of one to five, with one being the cheapest and five being the most expensive, I'm rating the solution three out of five."

"It depends on the customer, what he wants."

"It is very cost-effective compared to the tools I worked with in the past. The company is gaining a lot with respect to the cost factor. It provides agentless monitoring and in a very cheap way."
