Why collectl (V4.1.0-1) does not have subsystem "lustre"? What am I missing?

root@dgx1:~/pb/collectl/4.1.0/collectl-4.1.0# collectl --showsubsys
The following subsystems can be specified in any combinations with -s or
--subsys in both record and playbackmode. [default=bcdfijmnstx]
These generate summary, which is the total of ALL data for a particular type
b - buddy info (memory fragmentation)
c - cpu
d - disk
f - nfs
i - inodes
j - interrupts by CPU
m - memory
n - network
s - sockets
t - tcp
x - interconnect (currently supported: OFED/Infiniband)
y - slabs
These generate detail data, typically but not limited to the device level
C - individual CPUs, including interrupts if -sj or -sJ
D - individual Disks
E - environmental (fan, power, temp) [requires ipmitool]
F - nfs data
J - interrupts by CPU by interrupt number
M - memory numa/node
N - individual Networks
T - tcp details (lots of data!)
X - interconnect ports/rails (Infiniband/Quadrics)
Y - slabs/slubs
Z - processes
An alternative format lets you add and/or subtract subsystems to the
defaults by
immediately following -s with a + and/or -
eg: -s+YZ-x adds slabs & processes and removes interconnet summary data
-s-n removes network summary data
-s-all removes ALL subsystems, something that can handy when playing
back
data collected with --import and you ONLY want to see that data
