URL: https://github.com/apache/skywalking-nodejs/pull/142
Extend Node.js runtime metrics from **6 to 12** `instance_nodejs_*` meters
reported via `MeterReportService.collect`, building on the six meters
introduced in #139.
This PR is **metrics-only** — no gRPC/TLS/DNS/CommandService changes.
### Motivation
Operators need richer Node.js process/V8 visibility (array buffers, uptime,
malloc stats, heap generations) alongside the existing CPU/heap/RSS meters.
### Changes
#### Six additional meters
| Node.js source | Meter name | Unit |
| :--- | :--- | :--- |
| `process.memoryUsage().arrayBuffers` | `instance_nodejs_array_buffers` |
bytes |
| `process.uptime()` | `instance_nodejs_uptime` | seconds |
| `v8.getHeapStatistics().peak_malloced_memory` |
`instance_nodejs_peak_malloced_memory` | bytes |
| `v8.getHeapStatistics().malloced_memory` |
`instance_nodejs_malloced_memory` | bytes |
| `v8.getHeapSpaceStatistics()` old_space | `instance_nodejs_old_space_used`
| bytes |
| `v8.getHeapSpaceStatistics()` new_space | `instance_nodejs_new_space_used`
| bytes |
**12 total** with the six baseline meters: `process_cpu`, `heap_used`,
`heap_total`, `heap_limit`, `rss`, `external_memory`.
#### Other
- `SW_AGENT_RUNTIME_METRICS_HEAP_SPACE_DETAIL` (default `true`); when
`false`, skip `getHeapSpaceStatistics()` and report `old_space_used` /
`new_space_used` as `0`.
- Process CPU: `process.cpuUsage()` user + system, normalized by **logical
CPU count** (0–100%).
- README: twelve-meter table + env documentation.
- Unit tests: `tests/runtime/RuntimeSampler.test.ts`,
`tests/runtime/RuntimeMetricsCollector.test.ts`.
- CI: `TestUnitRemote` matrix on Node **20 / 22 / 24** (`tests/remote`,
`tests/config`, `tests/runtime`).
- Express plugin e2e: `meterSize: 12`, assertions for all twelve meters.
