Executive SummaryUpdated on Dec 28, 2025
Zabbix and Splunk Observability Cloud compete in the monitoring and observability space. Zabbix has an advantage in terms of cost-effectiveness and flexibility, while Splunk is superior in offering advanced features and customer support.
Features: Zabbix is open-source, providing flexibility and scalability to monitor almost anything. Its customizable dashboard and integration with other open-source tools enhance its usability. Splunk Observability Cloud offers end-to-end visibility and real-time data analysis with customizable dashboards that deliver powerful visualizations, albeit at a higher cost.
Room for Improvement: Zabbix needs enhancements in user interface usability for non-technical users, improved reporting capabilities, streamlined network monitoring integration, and advanced automation features. Splunk, while robust, is complex and could improve in user interface usability and third-party tool integration, with room for refinement in machine learning features and alerting systems.
Ease of Deployment and Customer Service: Zabbix's on-premises deployment is supported strongly by its community, but lacks formal support without additional payment. It requires technical expertise for smooth deployment in hybrid cloud environments. Splunk, primarily used for public cloud environments, offers robust deployment options with solid customer support, though at a higher price.
Pricing and ROI: Zabbix is free and open-source, offering optional paid support for business users. It provides high ROI due to zero licensing costs, helping reduce downtime and enhance scalability. Splunk Observability Cloud is costly, impacting budget decisions for businesses, but offers excellent ROI for those seeking advanced observability features.
