[Collectl-interest] collectl says "system does not have lustre modules installed"!!

Hi,

I want to use collectl (V4.1.0-1) to get lustre
(version=2.12.2_178_ga0680fe_dirty) specific stats. But, it says "-sl
disabled because this system does not have lustre modules installed"! But,
system does have the necessary lustre modules. Can somebody help in
resolving this issue.

root@dgx1:~# collectl -sL
Use of uninitialized value $strace in pattern match (m//) at
/usr/share/collectl/formatit.ph line 178.
Use of uninitialized value $speed in numeric gt (>) at /usr/share/collectl/
formatit.ph line 181.
-sl disabled because this system does not have lustre modules installed
Error: no subsystems selected
type 'collectl -h' for help
root@dgx1:~#

root@dgx1:~# collectl -sl
Error: invalid subsystem 'l'
