I want all 3 resource usage and I want to monitor them every second. I looked at /proc/pid/stat, but I am not sure whether I am getting the required details.

The resources include cputime, disk usage and network usage. It seems to me, that stat /proc/ might be quite exact and also /proc//stat contains the time in clock ticks since system start. 18 I want to use the /proc to find the resource usage of a particular process every second.

But there might be other methods to find the start time of the process.

The bandwidth needs to be divided by the uptime of the process, which can be found by clock(3). You can read the IO bytes for each used interface. cat /proc/3553/net/devįace |bytes packets errs drop fifo frame compressed multicast|bytes packets errs drop fifo colls carrier compressedĮth0: 23650521 158896 0 0 0 0 0 9457 720802 4696 0 0 0 0 0 0 It seems you can see snmp values of a process in /proc//net/dev_snmp6/ at least for IP6: ifIndex 4īut quite likely that is a special kernel feature I eventually compiled in. iftop is another terminal-based free open source system monitoring utility that displays a frequently updated list of network bandwidth utilization (source and.
