Hello guys,

I have just started building a high-available site using ubuntu server 9.10. I am using moodle. The thing is that i want to write an application using curses, to show the status of the apache servers, mysql servers and the nfs server. I can check the mysql from the c api, but how can i check the status of apache and nfs?

Ideas are very much appreciated.

what "status" do you want to know about apache? Is it running? Is it running an functional, etc..? If you just want to see if it is up you could check the httpd.pid file and make sure it exists using kill(pid,0). you could send a HTTP request to the server-status page and parse that.

mod_status - Apache HTTP Server

for NFS - what do you want to know? You could perform a read/write test. create a file with certain pattern(0101...) and then read it back. keep track of timings etc..

just a thought.
