monitoring software
 

i'd like to have some tool to monitor the processes and the file reads and writes.
under windows, there are the systernals softwares to do just that:
Process Explorer to show all the processes in parent-child hierarchy, view all the process info, the security, the handles, the libraries, dependencies, opened files, current operation, context switches and so on;
File Monitor to see all the accesses to files by any program, reads, opens, writes, with filter capabilities

is there anything on linux?
for the files i havent seen anything at all, for the processes there's top, ps, ksysguard, but they give very little info

thanks

lsof ?

The message you have entered is too short. Please lengthen your message to at least 10 characters

and 'pstree' will show you parent-child dependencies on processes

ok there are some commands to get some of the info
but didn't anybody ever develope some monitoring software for linux? for example ksysguard does some kind of monitoring, but it doesnt give much info

Try strace

usage:

strace -p pid1 -p pid2 -p pid3 -p pid4 -p pid4 etc ....
