check_diskstat

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
