I'm wanting to write a simple web-based tool to see the status of several servers at a glance. I know there are many solutions existing, but I can't learn as much about perl by just using one of those as I can by writing my own. The first step I want to do is call a script from cron that runs several basic monitoring tools (sar, vmstat, df, iostat, etc) and saves the output of each to a file. Then I'd parse those files up, and write a summary file. Easy enough. And I could certainly do it with by calling the tools one at a time. However, I'd like to get roughly 1 minute of vmstat, iostat, and sar output.... Simultaneously. So I'm supposing I'd want to fork off each process, and then when those are all done come back and run a script that then parses those results out for the individual statistics I'm looking for. I've never used fork before, and while it looks fairly straight forward what I am not sure of is how to make sure all of those forked processes have completed before moving on and parsing the files. Any pointers?
