Submit SuggestionEuropean alternatives to Datadog for monitoring servers, networks and cloud services include Zabbix (Latvia), Checkmk and Icinga (Germany) and Centreon (France). All four can be run on a company's own servers, so metrics and alerts stay in infrastructure the company controls. Datadog is a US company headquartered in New York that sells a hosted monitoring platform.
Datadog describes its product as cloud monitoring as a service: metrics from apps, tools and services are collected in one place and shown in dashboards, with alerting on top. The data is sent to Datadog's cloud, and the company is based outside Europe, which matters to organisations that want European jurisdiction over their operational data.
The listed tools are built mainly for infrastructure and network monitoring that the customer operates. That means running a server and a database, but also no usage-based subscription to a US cloud service. Anyone who depends on Datadog's application tracing and hosted log search will not find an identical European hosted product here, and Centreon comes closest with its log and experience monitoring. All tools are compared in the infrastructure monitoring category.
