Smart not for all devices #4720

sachaz · 2018-09-19T12:37:35Z

Relevant telegraf.conf:

[[outputs.prometheus_client]]
#   ## Address to listen on
listen = ":9101"

[[inputs.smart]]
devices = [ "/dev/ciss0 -a -d cciss,0", "/dev/ciss0 -a -d cciss,1", "/dev/ciss0 -a -d cciss,2", "/dev/ciss0 -a -d cciss,3", "/dev/ciss0 -a -d cciss,4", "/dev/ciss0 -a -d cciss,5", "/dev/ciss0 -a -d cciss,6", "/dev/ciss0 -a -d cciss,7" ]

System info:

FreeBSD 11.1-RELEASE-p13
telegraf-1.6.3

Steps to reproduce:

From the 8 devices in the telegraf.conf I got only 2 devices result :

smart_device_exit_status{device="ciss0",enabled="Enabled",host="poseidon.aquilenet.fr",model="",serial_no="",wwn=""} 0
smart_device_exit_status{device="ciss0",enabled="Enabled",host="poseidon.aquilenet.fr",model="Samsung SSD 850 PRO 256GB",serial_no="S251NX0H869352H",wwn="500253884027f72e"} 4
smart_device_exit_status{device="ciss0",enabled="Enabled",host="poseidon.aquilenet.fr",model="Samsung SSD 850 PRO 256GB",serial_no="S251NX0H869353L",wwn="500253884027f72f"} 4
# HELP smart_device_udma_crc_errors Telegraf collected metric
# TYPE smart_device_udma_crc_errors untyped
smart_device_udma_crc_errors{device="ciss0",enabled="Enabled",host="poseidon.aquilenet.fr",model="Samsung SSD 850 PRO 256GB",serial_no="S251NX0H869352H",wwn="500253884027f72e"} 0
smart_device_udma_crc_errors{device="ciss0",enabled="Enabled",host="poseidon.aquilenet.fr",model="Samsung SSD 850 PRO 256GB",serial_no="S251NX0H869353L",wwn="500253884027f72f"} 0

Expected behavior:

smart result on all disks

Actual behavior:

only 2 disks

Additional info:

on the system a request on other devices like following exemple works:
/usr/local/sbin/smartctl --info --health --attributes --tolerance=verypermissive -n standby --format=brief /dev/ciss0 -a -d cciss,7

@sachaz Can you add the output of your command:

/usr/local/sbin/smartctl --info --health --attributes --tolerance=verypermissive -n standby --format=brief /dev/ciss0 -a -d cciss,7

sachaz · 2018-09-21T15:49:48Z

Sure, here it is & thanks for your answer

I have telegraf-1.7.4-1.x86_64 installed on CentOS Linux release 7.5.1804 (Core).
Disks are behind the Hewlett-Packard P420i .
Disks can be reached with /dev/sg0 -d cciss,0 ... /dev/sg0 -d cciss,23
In the telegraf.conf, I put only one disk for testing " /dev/sg0 -d cciss,0" with

devices = [ "/dev/sg0 -d cciss,0"]

And here is the test output for smart part:

# telegraf  --test| grep smart
2018/09/25 11:33:00 I! Using config file: /etc/telegraf/telegraf.conf

#

sachaz · 2018-10-21T14:31:53Z

devices = [ "/dev/sg0 -d cciss,0"]

As I said it works for one or two disks, not for more :(

douginoz · 2021-01-13T08:04:28Z

I don't think the solution matches the problem.
I have the same problem, which is this:
If my telegraf.conf [input.smart] has the following, it works:
devices = [ "/dev/sg3 -d areca,12/2"]

which $telegraf --test|grep smart shows:

etc. etc. (The actual output is about 25 lines long).

But since /dev/sg3 is a hardware raid controller, there are many hard drives within it, which is why you have to specify the additional parameters (" -d areca, 12/2")

So I need to have multiple entries, one for each drive in the array:

devices = [ "/dev/sg3 -d areca,1/2", "/dev/sg3 -d areca,2/2", "/dev/sg3 -d areca,3/2", "/dev/sg3 -d areca,4/2"] etc etc

But as soon as I add the second one, it fails:

I can add the other, non-array drives all I want, for example this works:
devices = [ "/dev/sg3 -d areca,1/2", "/dev/sdb", "/dev/sdc", "/dev/sdd"]

I thought the problem was that it doesn't accept duplicate devices. For example, I would have thought this would fail:

devices = [ "/dev/sda", "/dev/sda"]

but it works. The only difference is that my configuration requires the '-d' parameter:
devices = "/dev/sg3 -d areca,1/2", "/dev/sg3 -d areca,2/2"]

which returns the 'smart_device,device=sg3,host=sophie exit_status=2i 1610524882000000000' error and only lists the first drive within the array.

For your reference, here's the output of Smartctl using the correct values
