Microsoft Azure NGINXaaS Monitoring
Microsoft Azure NGINXaaS - An Overview
Azure NGINXaaS (NGINX as a Service for Azure) is a managed NGINX deployment on Azure that provides load balancing, reverse proxy, and API gateway capabilities. Applications Manager's Azure NGINXaaS monitoring gives you comprehensive insight into NCU provisioning efficiency, system CPU usage, connection health, HTTP request/response status codes, cache hit ratios, per-worker statistics, upstream peer health, and TCP/UDP stream metrics.

Monitored Parameters
Navigate to the Category View by clicking the Monitors tab. Hover over 'Child Monitors' under Microsoft Azure in the Cloud Apps table, and then select the NGINXaaS monitor from the displayed tooltip. This action will display the bulk configuration view for Microsoft Azure NGINXaaS in three tabs:
- Availability tab gives the availability history for the past 24 hours or 30 days.
- Performance tab gives the health status and events for the past 24 hours or 30 days.
