Currently, the value is hard-coded to a limit of 100.

https://github.com/apache/drill/blob/master/exec/java-exec/src/main/java/org/apache/drill/exec/server/rest/profile/ProfileResources.java

If you are building Drill from source, you could fork off the Drill repo and 
modify the value for MAX_PROFILES from 100 to a higher value. A compile and 
deploy of Drill would then have this set at the new value.

Since the WebUI doesn't support pagination, this would be a good way to go 
about it. 

Please file a JIRA for this enhancement, so that this can be tracked in a 
future release. 

Thanks

On Drill WebUI, profiles tab does not have pagination and when many short
queries are running, sometimes very recently launched queries are not seen
from the profiles page.

How do I increase the number of profiles shown on the WebUI?

Thanks,
