Memory Limit Thresholds

You are able to set memory limit thresholds for the jobs of the different components in the a9s Data Service Framework. You can configure two thresholds per job:

• alert_if_above_mb: The job will alert if memory is above this threshold
• restart_if_above_mb: The job will restart if memory is above this threshold

Per default the property alert_if_above_mb is set to 2250 and restart_if_above_mb to 2450.

Configuration Properties

Configuration

To change the thresholds you can use an Ops file that sets these properties. The following example Ops file changes the default values for the backup-service and can be used as a base for your use case:

- type: replace
  path: /properties/backup-monit/thresholds?
  value:
    alert_if_above_mb:  3500
    restart_if_above_mb: 4096

- type: replace
  path: /properties/anynines-backup-manager/thresholds?
  value:
    alert_if_above_mb:  1024
    restart_if_above_mb: 2048
