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

"The alerting system in Checkmk really works properly."

"Checkmk helps me compare data and foresee issues."

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

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

"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."

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

"I really like the auto-discovery feature."

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

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 real-time troubleshooting and application segregation that you can do within it."

"It is very rock solid. We hardly have any hardware issues."

"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."

"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."

"When we have mobile operators who are signal partners, where one is the roaming host and another is the roamer, we are able to see their traffic. Their packets are able to detect if any faults to develop, and at what point they fail."

"The product is stable. I have never had any issue where we have lost an InfiniStream, or visibility from that particular InfiniStream, throughout the bank."

"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

"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."

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

"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 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."

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

"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 allow running scripts at varying intervals."

More Checkmk cons

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

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

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

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

"Being able to manage the packet flow switches in nGeniusONE would be great."

"I would like to see an improved level of stitching between IPs."

"I'd like them to make the product more user-friendly."

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

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."

"This product could be cheaper."

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

"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."

"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."

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

"The price is a little high."

Overview

Checkmk is a powerful tool for monitoring IT infrastructure, providing vital insights on servers, databases, network devices, and custom applications.

Primarily used for supervising IT infrastructure, Checkmk helps organizations ensure service availability by monitoring hosts, processes, load, storage, and network appliances. With support for both Linux and Windows environments across multiple data centers, Checkmk performs compliance checks and preserves historical data for core network devices.

Auto-discovery: Automatically identifies new hosts and applies monitoring rules.
Custom monitoring: Enhances MySQL performance tracking.
Slack integration: Provides immediate downtime alerts.
Graphical trend analysis: Offers 400 days of trend data.
Multiple site monitoring: Ensures seamless data synchronization through task automation.
Resource and infrastructure monitoring: Configures log factors to fit budget constraints.
System metric imports: Includes servers, SQL, file systems, and application monitoring.

What benefits and ROI should users look for in reviews?

Time-saving: Auto-discovery and task automation streamline processes.
Proactive alerts: Immediate downtime notifications optimize response times.

Cost efficiency: Resource monitoring aligned with budget constraints.

Checkmk is deployed extensively in large enterprise environments for monitoring critical infrastructure. It proves particularly useful under conditions of frequent power outages or network issues, helping maintain smooth operations. While the alert acknowledgment process and interface require improvements, and the lack of an agent-less platform complicates server management, the strengths in auto-discovery, integration, and comprehensive monitoring make Checkmk a strong contender for IT infrastructure monitoring.
