Steps to troubleshoot if you see "NO Data" in the Node VM tab
Problem statement: You are getting No Data under the garbage collection and event loop graphs such as GC Pause Time, GC Pause Frequency, and Event Loop Ticks Per Minute.
Prerequisite: The Node.js agent version should be 3.0.0 or higher.
Solution:
The APM Insight Node.js agent compiles the native module on your deployment platform using the node-gyp package.
Follow the below requirements of the node-gyp package, without which you will not get the GC and event loop metrics.
- Depending on your operating system, you must have the following:
- On Unix
- Python v3.7, v3.8, v3.9, or v3.10
- Make environment
- A proper C/C++ compiler toolchain, like GCC
- On macOS
- Python v3.7, v3.8, v3.9, or v3.10
- Xcode Command Line tools
- On Windows
- Python v3.7, v3.8, v3.9, or v3.10
- Visual C++ Build environment
- If your NPM version is 5.2.0 or higher, the NPX comes pre-bundled with it. So, for versions below 5.2.0, you must install NPX separately.
Even if your native module build fails, you will still get memory and CPU-related metrics, but not the GC and event loop metrics.
