I have setup an Etherboot system with an NFS root. I am looking for the best way to monitor file activity on this NFS mount, with an eye to optimizing the configuration. The information I think I need to do this is a log of file opens, reads, writes, closes, etc. What is the best way to achieve this? I have not seen any easy logging mechanism in the NFS system itself, so is there another system utility that might do the trick? I know "strace" can generate this kind of generic info (along with volumes of extraneous data), but I want to monitor ALL access from the point of mounting the NFS partition during the boot cycle, so "strace" is not the answer. My intention here is to figure out which system components should be maintained (compressed) in a RAM drive on the DC, and which should be maintained on the NFS mount. For instance, it is likely that shared libraries would be accessed constantly, and might be candidate for the RAM drive, whereas (in an embedded system, which might normally run a few scripts, then load an application) something like the shell (i.e., bash), might only be needed once during init, so it would be wasteful to maintain a copy (even compressed) in RAM. Maintaining "frequent use" components on the RAM drive would minimize impact on the network providing the NFS mount. Any suggestions appreciated.
