Monitor linux host NFS I/O on local mount points

[peterjsouza]

I am new to Splunk and as part of the evaluation i wanted to create a script that poled the NFS stats on one of our busiest CentOS hosts. I took the iostat.sh script that is in *nix app and tried to adapt it. Can someone point me in the right direction? THANKS!!
[Below is the script]

. `dirname $0`/common.sh

HEADER='Mount           rBlk_svrPS       wBlk_svrPS         opsPS         ropsPS   wopsPS'
HEADERIZE="BEGIN {print \"$HEADER\"}"
PRINTF='{printf "%-90s  %11s  %11s  %12s  %12s  %13s\n", mount, rBlk_svrPS, wBlk_svrPS, opsPS, ropsPS, wopsPS}'

    CMD='iostat -n -h'
    assertHaveCommand $CMD
    FILTER='/^$/ {next} /^Filesystem:/ {reportOrd++; next} (reportOrd<2) {next}'
    FORMAT='{mount=$1; rBlk_svrPS=$6; wBlk_svrPS=$7; opsPS=$8; ropsPS=$9; wopsPS=$10}'

$CMD | tee $TEE_DEST | awk "$HEADERIZE $FILTER $FORMAT $PRINTF"  header="$HEADER"
echo "Cmd = [$CMD];  | awk '$HEADERIZE $FILTER $FORMAT $PRINTF' header=\"$HEADER\"" >> $TEE_DEST

While not directly answering your question, take a look at http://apps.splunk.com/app/870/. This is the Add On for SoS, and includes an NFS iostat input for diagnosing Search Head Pool problems, however can probably be adapted to your needs.
