Disk I/O for all Multipath devices

What should I check then?
Can you please help?

Can you please help?

I'm trying

Does your multipath device vendor offer MIB files that you can use or have any information on where to get that data through SNMP?

You need to answer that, or at a minimum tell us what mpio device/driver you're using and we can try to research a bit for ourselves.

So... please answer the aforementioned question and we'll see if we can help.

Hello Sir,

How do I check about MPIO drivers. I am using Centos 6.6

[yunushaikh]

i am using MPIO provided by CENTOS

Nothing is standing out on the Exchange.

Show us the output of `ls /sys/block` from one of the multipath systems. Perhaps we can modify the plugin we suggested in the earlier thread to help.

[yunushaikh]

Thanks for showing the hope

Here is the output of that command
ls /sys/block

dm-0 dm-12 dm-16 dm-5 dm-9 loop3 loop7 ram11 ram15 ram5 ram9 sdac sdag sdak sdao sdas sdaw sdb sdbd sdd sdh sdl sdp sdt sdx

I am in very need of disk I/O on my servers for implementing nagios.

Starting with dm are the multipath devices.

Try modifying the check_all_diskstat.sh script as follows:

Code: Select all

#!/bin/bash

CHK=/usr/local/nagios/libexec/check_diskstat.sh
WARN=${1:-"200,10000,10000"}
CRIT=${2:-"300,20000,20000"}

for DEVICE in `ls /sys/block/dm*`; do
        if [ -L /sys/block/$DEVICE/device ]; then
                DEVNAME=$(echo /dev/$DEVICE)
                echo -n "$DEVNAME: "
                $CHK -d $DEVICE -w $WARN -c $CRIT | sed "s#=#_$DEVNAME=#g"
        fi
done

Sir but this plugin does not execute remotely.
I have attached the plugin which I used for Disk I/O but that is not pulling multipath devices.

Will you be able to make any changes to this script. Please check.

Or Is there any possibility to execute the plugin which you have provided remotely.
Thanks for help in advance

It appeared that you worked through running the plugin remotely in the other thread you linked at the beginning of this thread.

This plugin will not accept the -H argument, but it should run over NRPE just fine. Please follow the same methodology you did before to get this working:
