System Monitoring

A new local system monitoring feature has been added, allowing to monitor numerous vital server metrics.

Most important metrics will be displayed when doing a pm2 ls:

┌─────┬─────────────────┬─────────────┬─────────┬─────────┬──────────┬────────┬──────┬───────────┬──────────┬──────────┬──────────┬──────────┐
│ id  │ name            │ namespace   │ version │ mode    │ pid      │ uptime │ ↺    │ status    │ cpu      │ mem      │ user     │ watching │

host metrics | cpu: 1.6% 42.9º | mem free: 52.0% | wlp0s20f3: ⇓ 0mb/s ⇑ 0mb/s | disk: ⇓ 0.199mb/s ⇑ 0mb/s /dev/nvme0n1p3 88.25% |

All server metrics will be available to pm2.io:

Disabling system monitoring

# Disable system monitoring
pm2 set pm2:sysmonit false
# Enable system monitoring
pm2 set pm2:sysmonit true

PM2.io bandwidth reduction

Data quantity sent from PM2 to PM2.io has been reduced by 80%, thanks for a json patch differential system. Much more data can now be exposed (metrics, actions) to PM2.io

Other fixes

  • feat: added args and full script path to monitoring data
  • fix: regular local ip check
  • fix: pm2 agent watchdog has been consolidated and fixes freezing issues
  • fix: modules bumped
