The consultants recommended the CheckMK monitoring system to the client, as it provided greater added value compared to the previous system, such as integrated plugins, an easy-to-use graphical interface and ready-made interfaces to cloud services. The advantages of the new system were presented in a proof of concept.

Following the creation of a rollout concept, CheckMK was implemented at the customer's premises. For the monitoring system, 12,000 services were distributed to the target systems with the help of distribution software and manual deployment by the consultants. Due to the high number of monitored services (over 400,000, previously approx. 30,000), a new action profile was created and the customer decided to further expand the monitoring system. Nevertheless, the resources required remain low: a single CheckMK server monitors hundreds of thousands of services. The customer received a comprehensive overview of all relevant information on services, applications, networks, utilization, bandwidth, hardware and connected components in real time, automated, uncomplicated and clearly arranged on flexibly adaptable dashboards.

At the end of 2020, almost one million metrics were being monitored. In the next step, the monitoring was linked to a ticket system so that administrators receive a corresponding, detailed message in the form of a ticket when events occur and can resolve potential problems directly.
