check-disk-usage
Check disk capacity and inodes based upon the gem sys-filesystem.
Can adjust thresholds for larger filesystems by providing a 'magic factor'
(-m
). The default, 1.0
, will not adapt threshold percentages for volumes.
The -l
option can be used in combination with the 'magic factor' to specify
the minimum size volume to adjust the thresholds for.
Refer to check_mk's
documentation on adaptive thresholds.
You can also visualize the adjustment using
WolframAlpha with the following:
y = 100 - (100-P)*(N^(1-m))/(x^(1-m)), y = P for x in 0 to 1024
Where P = base percentage, N = normalize factor, and m = magic factor
check-fstab-mounts
Check the mount points in /etc/fstab to ensure they are all accounted for.
metrics-disk-capacity
Acquire disk capacity metrics from df
and convert them to a form usable by graphite
metrics-disk
Read /proc/iostats for disk metrics and put them in a form usable by Graphite. See iostats.txt for more details.
metrics-disk-usage
Based on disk-capacity-metrics.rb by bhenerey and nstielau. The difference here being how the key is defined in graphite and the size we emit to graphite(now using megabytes), inode info has also been dropped.
check-smart-status
Check the SMART status of hardrives and alert based upon a given set of thresholds
check-smart
Check the health of a disk using smartctl
check-smart-tests
Check the status of SMART offline tests and optionally check if tests were executed in a specified interval
This is a sample input file used by check-smart-status and check-smart, see the script for further details.

If you are verifying certificates in the gem install you will need the certificate for the sys-filesystem
gem loaded
in the gem certificate store. That cert can be found here.
