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.

Generates close to real-time alerts so users can resolve issues, but needs more integration and public cloud monitoring features
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 most valuable features of PRTG Network Monitor are bandwidth utilization, user-friendliness, all past report simple retrievals, and timeout features. Additionally, if the solution does go down it is simple to bring it back."
"PRTG Network Monitor has positively impacted my organization; before PRTG Network Monitor, it was very difficult to monitor a wide variety of sensors, but since implementing it, which supports numerous sensor types and protocols, it has become much easier for us to monitor servers, virtual systems, and cloud services to some extent."
"PRTG Network Monitor is user-friendly and offers flexible alerting systems."
"The feature whereby it shows when my hard drives are moving towards thresholds that would be considered outages, before they reach that point - that is valuable."
"The sensors and probes are great, nice and lightweight, they don't take up too many resources on the system. We just deploy them out and they start reporting instantly."
"It is easy to use and intuitive, which is really important. It does what it says on the box by giving you a visual of the state of what is going on at any one time."
"Network Discovery is a feature that our customers like a lot."
"The product offers good documentation that helps with initial training."
"It's easy to use."
"The most valuable feature is the flexible discovery mechanism."
"They have also accommodated many state-of-the-art technologies like Docker and ZooKeeper."
"The custom built integration is one of the most valuable features because you can see all the especially critical items."
"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."
 

Cons

"PRTG Network Monitor can be improved because the dashboard themes feel outdated."
"PRTG would be improved if it required less memory to run."
"With custom sensors, there is a lot of work which needs to be done in the background, just for it to be tailor-made for the specific thing that we are actually monitoring. We take a lot of time with the custom sensors. I would like to see the customer sensor be more robust and a bit more varied."
"The technical support service should be improved."
"The dashboarding definitely needs improvement."
"Scalability is the only major sticking point for me. There is a recommended number of sensors, which is around 10,000 and we're double that... The only option we have to scale is to buy another core, which would be a separate, stand-alone instance..."
"Sometimes, our PRTG Network Monitor system crashes and a lot of sensors go down."
"PRTG Network Monitor can be improved as there is a lot of manual cleanup needed, which could be reduced."
"Now it is stable, but they should design threshold parameters in percentage instead of raw values."
"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 inclusion of a feature to show a graphical view of the network would be a helpful improvement."
"There was a problem with Zenoss and storage monitoring."
"The AI aspect needs to improve."
"It would be ideal if the product offered sound alerts."
"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"
 

Pricing and Cost Advice

"The price was pretty good, very competitive."
"The pricing is okay and it is cheaper than some competing products."
"It's an annual license that is based on the number of endpoints that we're tracking and using."
"All monitoring system is close to the same pricing scheme."
"The pricing is comparable."
"The price of PRTG is reasonable. PRTG's competitors like SolarWinds and ManageEngine charge more for the same functionality."
"It's a cost-efficient tool."
"We have unlimited devices and sensors, and it is a bit pricey, but we do have unlimited sensors. With all things considered the price is fine, related to the solution itself. PRTG Network Monitor is good value for money."
"It depends on the customer, what he wants."
"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 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."
