Monitoring Service

This service monitors the health of your DCS servers.

It detects crashes or unwanted popups, full disks, too low server FPS or too high RAM usage. It also generates load information to be used with the /serverload command.

Servers that are considered RUNNING, PAUSED or STOPPED will be monitored for any unusual popup (login or lua error) or crashes of the respective DCS.exe or DCS_server.exe process. A heartbeat will be sent to DCS every minute. The maximum number of heartbeats a server can miss can be configured in your instance configuration in nodes.yaml

Configuration

The (optional) configuration file for this service has to be placed into config\services\monitoring.yaml:

DEFAULT:
  time_sync: true           # sync the PC time with a time-server every 12 hrs, default: false
  time_server: pool.ntp.org # and use this non-default time-server for it, default: Windows default
  thresholds:
    Drive:              # You cannot disable the drive check. If you do not specify anything, these values will be taken as default. 
      warn: 10          # Warn, if your drive where DCS is installed (or your C: drive), gets below 10% (default: 10)
      alert: 5          # Send an alert if your DCS drive (or your C: drive) gets below 5% (default: 5)
      message: "Available space on drive {drive} has dropped below {pct}%!\nOnly {bytes_free} out of {bytes_total} free."
    FPS:                # Optional FPS-check
      min: 30           # if FPS reaches a min of 30 (default: 30)
      period: 5         # for at least 5 minutes (default: 5)
      message: "Server {server} FPS ({fps}) has been below {min_fps} for more than {period} minutes."
      mentioning: true  # and mention the admins (default: true)
    RAM:                # Optional RAM-check
      max: 32           # if RAM exceeds 32 GB (default: 32)
      period: 5         # for at least 5 minutes (default: 5)
      message: "Server {server} RAM usage is {ram} GB, exceeding the maximum of {max_ram} GB for more than {period} minutes."
      mentioning: true  # and mention the admins (default: true)

To configure the DCS server monitoring, you can change these values in your nodes.yaml and scheduler.yaml:

nodes.yaml

MyNode:
  DCS.dcs_serverrelease:
    max_hung_minutes: 5   # maximum heartbeats a server can miss (default: 3)

plugins/scheduler.yaml

DCS.dcs_serverrelease:
  schedule:
    00-24: YYYYYYY  # the server (and its DCS_server.exe process) should run 24x7
