Looking for a way to monitor kernel parameter usage



This is how I'd monitor file system handles:

[root@moon linux]# sysctl -a | grep file
fs.file-nr = 1472       0       6815744
fs.file-max = 6815744



I can see there are 1472 file handles in use.


But what about other parameters?


[root@lxpsapmoon linux]# sysctl -a | grep shm
kernel.shmmax = 4294967295
kernel.shmall = 4294967296
kernel.shmmni = 4096
kernel.shm_rmid_forced = 0
vm.hugetlb_shm_group = 0


I am lookint for a scripted (hopefully), reliable solution for monitoring important usage of important kernel parameters.


I am looking for functionality similar to the kcusage/kcalarm suite of tools on HP-UX
