Use Dynamic Float Value with DBSCAN

Splunk Search

Dear all!

I am trying to use a dynamic value for my epsilon in the MLTK in Splunk:

map search="search index = cisco_prod 
| timechart span=1h count as logins_hour 
| timewrap w series=short| fields - logins_hour_s6|table logins_hour_s*|transpose 0| fit DBSCAN  \"row *\"  eps=$eps$"

This doesn't return anything if eps is a float, only when I first round the dynamic variable.

However if I run the same search with a static float value for eps instead of my variable, it returns the clustering I am looking for.

Has anyone an idea what's wrong with my dynamic search?

Thanks!
