Quotes From Members

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

Pros
"I really love the Data Explorer. I use it all the time to go in and craft exactly what I need to see. I'm able to then take that story and explain it to the executives. I've done that a couple of times and it is helpful.""In terms of the solution’s real-time visibility across our network infrastructure, I have not been able to find any other monitoring or netflow visualization tool that gives me the kind of information I get from Kentik. If I need to take a deep-dive into something that I see, it's really easy for me to do that. Whereas with most other things, I have to use five or six other tools to get that kind of data, with Kentik, I have it all in one place.""Having the API access allows us to do a great deal of automation around a lot of our reporting and management tools.""We're also using Kentik to ingest metrics. It's a useful feature, and its response time, whenever we're pulling back the data, is higher than our on-prem solution.""I am able to do a lot of work on the visualization end to create different visualizations and different ways to get information out of it.""The drill-down into detailed views of network activity helps to quickly pinpoint locations and causes. All the information is there.""The most valuable feature is being able to pull traffic patterns; to and from destinations. We're able to understand where our traffic is going, our top talkers from an AS set, as well as where our traffic's coming from.""The most valuable features have been anything around traffic engineering: being able to determine the source or destination of a surge of traffic, whether it's DDoS-related, or a customer just happened to have a sudden uptick in traffic. Being able to tell where that's coming from or where it's going to enables us to do things based on that."

"The most valuable feature is the monitoring of processes.""This is a very good solution and it is simple to use, for any company.""The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers.""The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need.""An excellent solution that is easy and intuitive to implement.""The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."

"I really love the activity library. It gives the flexibility to discover data and metrics about my interface and data server.""It improves the status of my infrastructure, from networking devices to real-time machines.""The scalability is good. You can improve a remote host or the clustering. This gives it the flexibility to monitor another infrastructure remotely.""The best feature is that it lets me know what is going on. I need to know if something has gone down, I need to know if something is running very slowly. PRTG tells me that.""Its proactiveness is its most valuable feature. We already know when we come in, in the morning, if a server or site is down, as opposed to someone telling us.""One of its valuable features is the fact that it handles multiple operating systems... And I like the fact that it tells me when things are about to fall over, which means I can preempt it and not have to wake up at three in the morning to fix it.""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.""Speed of deployment is one of the most valuable features."

Cons
"I've checked out the V4 version of the interface and it's still a little bit clunky for me to use. I still go back to the old interface. That's definitely one that they still need to work on. It doesn't seem like everything that you get in the V3, the older interface, is there. For instance, I was trying to add a user or do the administrative tasks in V4, and I couldn't figure out where I was supposed to do that.""There is room for improvement around the usability of the API. It's a hugely complex task to call it and you need a lot of backing to be able to do it. I should say, as someone who's not in networking, maybe it's easier for people who are in networking, but for me that one part is not very user-friendly.""I would like to see them explore the area of cost analysis.""The only downside to Kentik, something that I don't like, is that it's great that it shows you where these anomalies lie, but it's not actionable. Kentik is valuable, don't get me wrong, but if it had an actionable piece to it...""They're moving more in a direction where they are saying, "Hey, here's information that you may be interested in or may a need," before the question has to explicitly be asked. Continuing to move in that direction would be a good thing.""We asked for a way, regarding the potential networks that exist, to hook Kentik up with external tools like peering DBs to correlate things together and see what we can do... This is all in the [next] beta now.""I believe they're already working on this, but I would love for them to create better integrations from network flow data to application performance — tracing — so that we could overlay that data more readily. With more companies going hybrid, flow logs and flow data, whether it be VPC or on-prem, matched with application performance and trace data, is pretty important."

More Kentik Cons »

"The interface could be more user-friendly.""I would like to see support for notification via SMS.""I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space.""I would like to see more customization in the network map because it is a bit tricky to use it.""They need more documentation for the plugins.""There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."

More Nagios XI Cons »

"I would like to see a more robust platform and a new dashboard. In addition, the code is good, but it needs improvement.""There seems to be a big jump from the basic scan to the really thorough scan. There is a big jump in the quantity of sensors it uses for certain things. One minute you might get ten and then the next you get 200. There seems to be a big jump between the two at times.""It probably has this already, but if it had a mobile app that would be helpful. For example, on a day like today when I'm out, if I could just fire it up and see green, green, green, green, green or red, that would be good.""It would be good if there were better graphical interfaces when you have it on multiple monitors... Because we have so many servers, things can get lost in the fog a little bit. Maybe having a better way of showing different geographies, Flash, etc., would help.""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.""The Desktop app is good but it can be really sluggish at times, especially when you're editing different elements.""In terms of sensors and probes, it would be really cool if PRTG had a purely Azure-based solution. We had to install a probe on one of our cloud servers and then let that probe out from there. It would be really cool if it just monitored Azure without having to install something on the device.""Sometimes, it is difficult to drill down further to get information, e.g., if we saw spike in traffic, then we would want to drill down and find out what is causing that spike in traffic."

Pricing and Cost Advice
"We have an annual contract with Kentik that we renew each year for a set number of licenses. We also have some burstable licenses which we can spin up and spin down, and those are paid as they are used."

More Kentik Pricing and Cost Advice »

"We are using the free version of this solution.""This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years.""The licensing fees for this solution are approximately $3,000 USD per year.""The pricing is high with separate licensing for the product and support."

More Nagios XI Pricing and Cost Advice »

"The price was pretty good, very competitive.""The pricing is not too bad. It's not massively expensive, and the ability to upscale or even downscale licenses every year is brilliant for us.""On a yearly basis, I believe it's between £1,200 and £1,500.""We've got 1,000 nodes and I believe it's a few hundred quid a month.""Because we are only on the free version, we have a limited number of sensors. Therefore, we are not monitoring as much as we want to be to obtain historical information.""We are licensed for 2500 endpoints.""We pay for a perpetual license and we have a support fee.""We've got the unlimited package... I believe it was around the £15,000 per year mark."
