db2pd output

I am quite confused with the 'db2pd' output.
When I fired the command as "db2pd -d <DB_NAME> -logs" the output on screens..,

Logs:
Current Log Number 22724

Method 1 Next Log to Archive n/a

Method 2 Archive Status n/a

Can anyone tell me, Why status of some field is shows as not collected??
Is there any harm in that??
Or do we need to enable some parameters in order to collect the status??
