Development of a Comprehensive Monitoring Strategy for Hybrid Systems

I need to develop a comprehensive monitoring strategy that provides end-to-end visibility into our hybrid systems (a mix of cloud-based and on-premise infrastructure). The target audience for the monitoring strategy document is IT managers and system administrators.

Specifically, we need to monitor key services like our e-commerce website, customer database, and internal CRM application. Consider response time, error rate, and resource utilization as important KPIs, prioritizing response time and error rate. We currently use some basic Nagios monitoring, which we would like to integrate where appropriate, but are open to new tool recommendations.

Could you help by:

• Identifying key performance indicators (KPIs) for infrastructure, applications, and user experience, tailored to a hybrid environment.

• Recommending monitoring tools (e.g., Nagios, Datadog) and log management solutions (e.g., ELK Stack), taking into account our existing Nagios setup.

• Designing alerting mechanisms with appropriate thresholds to minimize false positives.

• Provide the strategy in a document format, including diagrams of the monitoring architecture. The diagrams should provide a high-level overview of the system and a more detailed component-level view showing data flow.
