Yes you can pass all data including performance data back in one call.
Here's an example output from check_wmi_plus

Plugin data:
Overall Status - OK (Sample Period 300 sec) - Logical Drive Name="C:" 
(OK) - _PercentIdleTime=99%, _PercentBusyTime=1%, _PercentDiskTime=1%, 
_PercentDiskReadTime=0%, _PercentDiskWriteTime=1%, 
_DiskReadBytesPersec=0B/sec, _DiskReadsPersec=0/sec, 
_DiskWriteBytesPersec=51.6KB/sec, _DiskWritesPersec=3/sec, 
CurrentDiskQueueLength=0, _AvgDiskQueueLength=0.0, 
_AvgDiskReadQueueLength=0.0, _AvgDiskWriteQueueLength=0.0

Performance Data:
'_PercentIdleTimeC:'=99; '_PercentBusyTimeC:'=1; '_PercentDiskTimeC:'=1; 
'_PercentDiskReadTimeC:'=0; '_PercentDiskWriteTimeC:'=1; 
'_DiskReadBytesPersecC:'=0; '_DiskReadsPersecC:'=0; 
'_DiskWriteBytesPersecC:'=52838; '_DiskWritesPersecC:'=3; 
'CurrentDiskQueueLengthC:'=0; '_AvgDiskQueueLengthC:'=0.0; 
'_AvgDiskReadQueueLengthC:'=0.0; '_AvgDiskWriteQueueLengthC:'=0.0;

You just need to make sure all the field names (for perf data) are 
different. Something like PNP4Nagios will draw multiple graphs using 
output like that.

If you didn't like returning it all at once you could:
- You could rewrite the plugin to be run on a cron schedule. When it is 
run, collect all 30 bits of information and pass the data to Nagios as 
passive results to 30 different services.
- You could rewrite the plugin to check multiple parameters at once eg 
10 and then pass all 10 back to Nagios as an active plugin. Then just 
call it 3 times (making it parameter driven to return group1 data, 
group2 data group3 data etc)
