check_diskstat
Linux disk IO check. Reads /sys filesystem directly to query tps, read, write, avg. request size, avg. queue size and avg. wait time.
EXAMPLE OUTPUT

$ ./check_diskstat.sh -d sda -W 10 -C 20
summary: 3 io/s, read 32 sectors (0kB/s), write 4216 sectors (43kB/s), queue size 0 in 48 seconds | tps=3io/s;;; read=341b/s;;; write=44970b/s;;; avgrq-sz=24;;; avgqu-sz=0;10;20; await=43ms;;;


USAGE

./check_diskstat.sh -d DEVICE [ -w tps,read,write -c tps,read,write ]
| [ -W qlen -C qlen ] | -h

This plug-in is used to be alerted when maximum hard drive io/s, sectors
read|write/s or average queue length is reached.

-d DEVICE DEVICE must be without /dev (ex: -d sda)
-w/c TPS,READ,WRITE TPS means transfer per seconds (aka IO/s)
READ and WRITE are in bytes per seconds
-W/C NUM Use average queue length thresholds instead..
-b Brief output.

Performance data for graphing is supplied for tps, read, write, avgrq-sz,
avgqu-sz and await (see iostat man page for details).

Example: Tps, read and write thresholds:
./check_diskstat.sh -d sda -w 200,100000,100000 -c 300,200000,200000

Example: Average queue length threshold:
./check_diskstat.sh -d sda -W 50 -C 100
