General Information
For general information on monitoring, please refer to the dedicated article (How do I monitor my platforms performance?).
Getting Started
Compute metrics provide meaningful information about compute capabilities of the platforms web servers.
Available Metrics
CPU Usage (%)
- CPU IO Wait
The percentage of time that the CPU is waiting for input/output operations aggregated across all web servers. A high CPU IO Wait may indicate that the database is under-provisioned, meaning that it is not meeting the performance requirements of your workload. - CPU System
The percentage of time that the CPU is handling system operations aggregated across all web servers. - CPU Application
The percentage of time that the CPU is handling user operations aggregated across all web servers. A high CPU Application may indicate that:- your source code is consuming a lot of CPU and you should investigate and optimize it for performance
- the platform is under-provisioned and does not meet the performance requirements of your workload
Memory Usage (Mo)
- Memory Used
The amount of memory in use aggregated across all web servers. A high memory usage may indicate that:- your source code is consuming a lot of RAM and you should investigate and fix issues (memory leaks, etc.)
- the platform is under-provisioned and does not meet the performance requirements of your workload
- Memory Swap
The amount of swap space aggregated across all web servers. When happening, contents not currently in use are swapped to a disk to make the memory available for other applications or processes. A high memory swap can severely slow down the performance of your application.
Load (must be under 1.0)
The load averaged over a 5 minute window.
