Linux Filesystem Stats Discovery Rule - w/DM support

[Jburkemx]

I modified ghillan device_mapper script from https://www.zabbix.com/forum/showpos...77&postcount=7 to handle normal /dev's and also device mappers.

The primary change was to add a check to see if the filesystem name (returned from /proc/mounts) has "mapper" in it, if so it does another step is done to find the /dev/dm-? for each /dev/mapper device.


When called without arguments, device_mapper.pl returns three values for each mount:
FSNAAME = the mount point
FSDEVICE = the /dev/ device (sda or dm-)
FSTYPE = the filesystem type.

for example, the root filesystem:
"{#FSNAME}":"\/",
"{#FSDEVICE}":"dm-7",
"{#FSTYPE}":"ext4" },


User Parameter for your zabbix_config:

UserParameter=device_mapper[*],/usr/bin/device_mapper.pl $1 $2

Discovery Template is attached.


ToDo: Add step to get device for UUID mounted drives (/dev/disk/by-uuid/xxxxx-xxxx-xxx)

Works great ! Thanks for sharing

Btw, double check the template items and graphs. I think I made some minor configuration errors in them. Specifically in regards to the Read/Write times and IO times.

I see, I set units to ms and looks like I'm getting the right values, is that enough?

Yes, i think that was it.

Fixed the trailing comma on the last object and removed the empty object. No more "no value received for macro".
