Monitor disk space without gkrellm


Hi all,

Currently I am running gkrellm for the sole reason to monitor disk space. When a partition reaches 95% full the pc will be halted to prevent data loss.

I'd like to get rid of gkrellm, but want to keep monitoring disk space. Is there an elegant way to do this? Maybe through conky (fork of torsmo)? Surprisingly google nor LQ came up with anything.

Cheers, Leon.

You could have a cron job check for the space left periodically.
percentleft=$(df / | tail -n 1 | tr -s ' '| cut -d' ' -f5)
if [ ${percentleft%\%} -lt 5 ]; then shutdown -s 500 -h +5 'Disk space critical'; fi

Using quotas may be a more elequent way to handle this.

Thanks, but what I had in mind was more a kind of real-time monitoring. So that it will notice a near-full partition when copying large amount of files, or ripping a DVD.

Cheers, Leon.

I believe that using quotas you could have a soft limit and a hard limit. On the softlimit you are warned immediately and on a hard limit, you aren't allowed to continue (save the file).

This may work better if you are on a system with several users.

You might read through the ulimit man page. In any case I think that a warning, perhaps using xwindow, would be better than a shutdown.

A program that would do this, ( perhaps there are some ), may get the info from the kernel and run as a service. There may be a kernel feature for this. You could try googling for terms like "disk limit kernel alarm". You could also look at the source for gkrellm and gut it out, removing the display code and retaining the monitoring and action parts of the code.

Someone else on this site probably knows of the perfect program for you!
