To check status information:

  • Use the command status in the CLI.
  • See the monitoring and status information in the netCDF file.

CL61 alerts can have up to 4 statuses.

The alert limits are based on alert configuration parameters. See CL61 configuration parameters.

Table 1. Alert status values
Value Description
CLI netCDF
0 0 OK
I 1 Indication
W 2 At least one warning active, no alarms
A 3 At least one alarm active

The following tables list the status information in the order that it appears in the CLI status information response. The order and naming of items in the CLI status information response and in the netCDF file differ slightly.

The netCDF files contain information about the active status values and possible corrective actions in error situations. If you need further information, contact Vaisala.

Block 1 of the CLI status information is for reference and displays a few basic settings.

Block 13 of the CLI status information is for reference and displays a few values for monitoring purposes.
