Application performance and System monitoring at Agos

A reasonably priced tool for system and application monitoring

The main room for improvement is in the solution's presentation and the integration area. In our company, we use the integration capabilities from ServiceNow. We also have another big monitoring solution in place in our company, which is Dynatrace. At the moment, there doesn't exist an out-of-the-box integration for Dynatrace. I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most. The only implementation of Checkmk that allows high availability is the virtual appliance that has the option for the availability of a different box. Otherwise, you have to find a way to implement it manually with some custom solution, which could be an improvement.

Quotes from Members

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

Pros

"Checkmk was built on a platform that was user-friendly, and I could build my charts easily."

"We can monitor multiple sites using the product."

"The most valuable features of Checkmk are its resource monitoring, infra monitoring, and log factor configuration."

"It's versatile, scalable, and easier to use compared to other solutions like Nagios and OMD."

"Overall, from one to ten, I rate Checkmk a nine."

"The initial setup of Checkmk was easy...It is a very stable solution."

"The most valuable feature of the solution is that it has a lot of different pieces, and they all work together...It is a very scalable solution. Scalability-wise, I rate the solution a ten out of ten."

"Checkmk helps me compare data and foresee issues."

More Checkmk pros

"It allows us to get quicker resolutions. We can see exactly what is using up the bandwidth, so we can assist end users."

"The technical support is really good. They will go above and beyond, if you are running into a problem. You can go to a sales engineer, who will engage technical support to help you out."

"It helps us get to root cause quickly. With utilization and consumption of bandwidth, we can usually see what application is taking as much as they should (or shouldn't), then account for it accordingly."

"The most valuable feature is utilization."

"I love the single pane of glass view. It makes it easier to not have to navigate everywhere. It allows more simplistic visibility, without having to go from tool to tool to tool, or from window to window to window."

"We use it for monitoring whenever we update a new circuit or site."

"The tool has the ability to look back within a month's data. It is very easy to navigate within the tool and troubleshoot the problem, compared to other solutions that we've used in the past."

"It has cut our troubleshooting down by days. Once we have a product in place, we show people examples of how it can streamline their troubleshooting process."

More NETSCOUT InfiniStreamNG pros

Cons

"Sometimes we receive alerts, and it can become annoying when you acknowledge an alert. It is very clunky when you acknowledge the alert. The process is not very intuitive, and there are instances where it feels a bit cumbersome to acknowledge an alert."

"The initial setup is a bit complex."

"Checkmk does not allow running scripts at varying intervals."

"If an alert is generated for a specific pattern in the log, and if Checkmk catches that log, it will stay there even after the alert is resolved."

"In Checkmk, the documentation can probably be improved a bit more."

"I think that the integration and the exporting of the data collected are areas where Checkmk lacks but should try to improve the most."

"The main challenge for us is that we're moving from Nagios to Checkmk, and we're still getting used to the new way of working."

"Checkmk does not work too easily with the PowerStore. I use a PowerShell script as Checkmk runs on Linux and a Windows system, connecting with the Checkmk agent."

More Checkmk cons

"There is a timeout feature that we have been asking for awhile."

"The single pane of glass feed still needs work."

"It's not able to communicate with our probes."

"Only problems that we have had are fiber issues going into the TAPs or vSTREAMs, which are usually local site issues."

"The NetFlow Collectors could handle more flows per minute."

"We don't use the single pane of glass view, even though we own it."

"The technology goes end-of-life on us every year, which is why I am looking forward to vSTREAM. I don't like when devices go end-of-life on us so quickly. If we can get more of an advanced notice of when an end-of-life is brought up, because our certification process within the organization takes a while."

"The monitoring and reporting tool needs improvement. Users want more information, such as the level of detail when doing a packet analysis. They want more detail to be able to isolate down to a specific point."

More NETSCOUT InfiniStreamNG cons

Pricing and Cost Advice

"The product is affordable."

"The price of Checkmk is cheaper compared to other enterprise products."

"Checkmk is a fairly reasonably priced solution."

"The price is a little high."

"The scalability is good, but it comes at a cost. E.g., if you need 100 InfiniStream because you are sending gigs or terabytes of data to one InfiniStream, then you will have to purchase another InfiniStream, which are not cheap."

"This product could be cheaper."

"To capture more with the solution that we bought, you have to buy another InfiniStreamNG, and there are only four ports in the back."

"I would like it to be more scalable with less spend."

"It can be scalable. It just costs too much. With a company as big as ours, it gets too expensive to accommodate every single site."
