Solution
You can adjust the broadcast rate of the salt beacon on that client system in the following configuration file, under the beacons section:
C:\ProgramData\National Instruments\salt\conf\minion.d\nisysmgmt.conf
beacons:
nisysmgmt_startup:
- run_once: true
- interval: 0
nisysmgmt_dynamic_grains:
- interval: 15
nisysmgmt_changes:
- interval: 15
nisysapi_changes:
- interval: 15
nisysmgmt_monitoring:
- interval: 15
ni_asset_health_monitoring:
- interval: 15
nisysmgmt_assets_monitoring:
- interval: 15
nisysmgmt_utilization_cleaning:
- interval: 15
nisysmgmt_status_checks:
- interval: 3
The interval property for each beacon is in seconds. If you remove that beacon definition entirely from the beacons section, it will be disabled on that client system. You should restart the NI Salt-Minion Windows service on that client after each change to the nisysmgmt.conf file.
