Hey all,

I am writing a daemon in perl which will check for load average, free disk space on a particular partition and free memory and send it as an updation query to another daemon.

I am supposed to check for these params at least twice in a minute. I was looking at perl modules which would give me this info - but after looking under their hood - most of them fire system command to launch a shell. Some of them do it via /proc which I would rather do myself. My queries are

1. What is faster - reading /proc/loadavg or uptime? I would say /proc/loadavg.

2. Are there any perl modules which are using XS to get these queries done faster without opening a shell?

3. Load average I can get through /proc/loadavg, free memory through /proc/meminfo. But how to obtain free disk space through proc? I am talking about 2.6.x kernels on RHEL4. I want to use /proc as much as I can because I would be reading from a file and not launching a shell.

Are there any other suggestions that you guys think would be useful in writing such daemons which do frequent updates? Thanks for going through my post.


regards,
Saurabh.
