Executive SummaryUpdated on Oct 10, 2024

NETSCOUT vSTREAM and Checkmk are competing in network monitoring and IT infrastructure management. Checkmk often has the upper hand due to its comprehensive features across a wide array of devices and services. However, NETSCOUT vSTREAM's unique traffic analysis capabilities make it a preferred choice for specific scenarios requiring in-depth network visibility.

Features: NETSCOUT vSTREAM is known for its robust network traffic analysis, providing detailed visibility into performance issues. It also excels in managing large-scale network environments. Additionally, it offers advanced analytics for nuanced traffic insights. Checkmk's strength lies in its extensive monitoring system that efficiently manages a wide range of devices. It offers a well-structured alert system and is highly valued for its comprehensive infrastructure observability. Checkmk also delivers efficient performance across multiple platforms.

Room for Improvement: NETSCOUT vSTREAM could enhance its breadth of device monitoring to compete more directly with broader solutions. Its integration with non-network devices is limited. There is room to improve user interface intuitiveness. Checkmk might improve in-depth network traffic details comparable to NETSCOUT's offerings. Its setup complexity in non-typical environments could be simplified. Further development of advanced analytics could expand its functionality.

Ease of Deployment and Customer Service: NETSCOUT vSTREAM is recognized for a simplified deployment process that supports large-scale networks, allowing for clear traffic data analysis. While its integration is seamless with network assets, customer service has less flexibility. Checkmk offers a comprehensive deployment model and responsive customer support, facilitating easier adoption and continuous assistance across different environments.

Pricing and ROI: NETSCOUT vSTREAM often requires higher initial investments, which can be justified for large operations seeking specific network traffic insights. Despite its cost, the platform provides valuable analytics for targeted needs. Checkmk is competitively priced, offering strong ROI due to its scalable monitoring system. Its budget-friendly approach provides expansive functionality and value suitable for varied business sizes.

Paolo Sala

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.

Keval Lodaya

Network Engineer at Inniti Network Solution

A user-friendly solution that is easy to install and improves visibility

I would like to see improvements made to the user guide. From my personal experience, it is helpful to see a list of steps describing what to do next in different situations. An example is what to do and what to back up in the case of certain types of failure. There are also cases where a customer can't understand specific features. Enhancements to the user guide would be helpful for this. More features for network fragmentation would be helpful.

Quotes from Members

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

Pros

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

"The alerting system in Checkmk really works properly."

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

"We can monitor multiple sites using the product."

"Checkmk helps me compare data and foresee issues."

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

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

More Checkmk pros

"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."

"One of the valuable features is the packet decoding."

Cons

"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."

"The initial setup is a bit complex."

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

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

"It is easy for tech-savvy people, but newcomers might find it intimidating."

"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."

"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."

More Checkmk cons

"I would like for it to have a smaller footprint of the virtual appliance and better performance."

"Room for improvement exists in filtering in the packet decode."

"I would like to see improvements made to the user guide."

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.

What are the key features of Checkmk?

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.
Historical insights: Long-term graphical trend analysis aids strategic planning.
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.
