Checkmk takes application monitoring to the next Level with Synthetic Monitoring


Share this press release over social media

Munich, April 30, 2024 - With Checkmk 2.3 released today, Checkmk extends IT monitoring with synthetic monitoring. Administrators and DevOps teams can use Checkmk Synthetic Monitoring to simulate user interactions with applications in order to monitor the availability, performance, and functionality of those applications from the user's perspective. Checkmk thus helps to build a monitoring stack that includes critical user journeys as well as the IT infrastructure to immediately resolve or proactively prevent incidents.

In addition, Checkmk continues to drive out-of-the-box monitoring for a wide range of workloads in hybrid and multi-cloud IT infrastructures. With the new release 2.3, IT service providers will also benefit from significantly enhanced cloud monitoring and even more automation. 

"For our customers, end-to-end visibility into their IT and rapid problem resolution are critical. They want to know immediately if a business-critical application is not working properly for end users, and whether the problem lies in the application or in the infrastructure. With Checkmk 2.3, we therefore seamlessly integrate application monitoring from the user's perspective into our Checkmk platform,"

Synthetic Monitoring: monitoring applications from the user's perspective

Checkmk Synthetic Monitoring allows for automated testing of application functionality, performance, and availability in order to view a system’s health from the users’ point of view. By simulating user interactions with an application from different geographic locations and devices under real-world conditions, Checkmk Synthetic Monitoring helps to proactively identify and resolve issues in critical user journeys before they negatively impact customer satisfaction and business operations. It enables you to test modern web applications, REST APIs, network protocols, and even local Windows applications, regardless of whether they have an API or run in the browser. At the heart of Checkmk Synthetic Monitoring is the leading open-source-based test automation tool, Robot Framework. Even IT administrators without in-depth programming knowledge can create synthetic tests for a wide range of use cases, such as the online store ordering process or loading times of documents in legacy systems. 

Web and certificate monitoring in Checkmk 2.3

Powerful and efficient monitoring of web services

The HTTP check for web service availability and performance monitoring has been completely redesigned to enable the monitoring of websites, including their certificates. This, as well as more detailed notifications – such as for outdated TLS versions and expiring website certificates – makes it easier to ensure the stability of critical web services. In addition, Checkmk 2.3 not only checks certificates provided over HTTPS but also any application that provides a certificate over a TCP port, such as databases. This allows man-in-the-middle attacks to be detected efficiently and quickly throughout the network. 

Next generation database monitoring

Now you can monitor all databases compatible with MS SQL queries with the redesigned MS SQL plug-in. The more powerful architecture enables monitoring of all local databases and in-depth monitoring of remote databases such as MS Azure SQL. The plug-in also supports a wide range of MS SQL setups and customized handling of long-running queries. 

Identify resource hogs

Developed in response to community requests, the top list dashboard dashlet helps IT teams keep track of their ten biggest pain points (hosts or services). For example, being able to view at a glance the systems with the highest resource usage in terms of CPU or disk space makes it easier to manage large IT environments.

Numerous visualizations of network connections

For deeper insights into the network topology and quicker mean time to resolution (MTTR), Checkmk 2.3 offers different modes of visualizing network connections. Users can choose whether they want all hosts and their relationships to be displayed, or a combined view of hosts and interfaces, or just hosts and interfaces with problems. 

Checkmk 2.3: easier, more efficient, and even more out-of-the-box monitoring

In addition to the many minor enhancements to its 2,000+ monitoring plug-ins, Checkmk 2.3 now supports monitoring of Redfish, Nutanix clusters and PureStorage FlashArrays. Numerous additional new features make working with Checkmk even easier and monitoring more efficient. For example, visual and functional upgrades make workflows more intuitive. To test configured notifications, events can now be simulated directly through the Checkmk interface, to ensure that everything works as expected in an emergency. 

Cloud capabilities in Checkmk MSP

Checkmk MSP, designed specifically for Managed Service Providers, now includes features previously reserved to Checkmk Cloud such as advanced monitoring of multi-cloud environments. Furthermore, Checkmk Cloud's agent capabilities increase the flexibility and efficiency of monitoring customer infrastructures. For example, MSPs can push monitoring data directly to their central Checkmk instance without the need for a remote site, saving time and effort when onboarding small customer environments. Auto-registration also minimizes effort by automatically adding new systems to monitoring.
