Telegraf 1.19 - Windows smart plugin does not work correctly with adaptec raid

[marianob85]

Relevant telegraf.conf:

 # Read metrics from storage devices supporting S.M.A.R.T.
 [[inputs.smart]]
   ## Optionally specify the path to the smartctl executable
   path_smartctl = "C:/Program Files/smartmontools/bin/smartctl.exe"

   ## Optionally specify the path to the nvme-cli executable
   # path_nvme = "/usr/bin/nvme"

   ## Optionally specify if vendor specific attributes should be propagated for NVMe disk case
   ## ["auto-on"] - automatically find and enable additional vendor specific disk info
   ## ["vendor1", "vendor2", ...] - e.g. "Intel" enable additional Intel specific disk info
   # enable_extensions = ["auto-on"]

   ## On most platforms used cli utilities requires root access.
   ## Setting 'use_sudo' to true will make use of sudo to run smartctl or nvme-cli.
   ## Sudo must be configured to allow the telegraf user to run smartctl or nvme-cli
   ## without a password.
   use_sudo = false

   ## Skip checking disks in this power mode. Defaults to
   ## "standby" to not wake up disks that have stopped rotating.
   ## See --nocheck in the man pages for smartctl.
   ## smartctl version 5.41 and 5.42 have faulty detection of
   ## power mode and might require changing this value to
   ## "never" depending on your disks.
   nocheck = "never"

   ## Gather all returned S.M.A.R.T. attribute metrics and the detailed
   ## information from each drive into the 'smart_attribute' measurement.
   attributes = false

   ## Optionally specify devices to exclude from reporting if disks auto-discovery is performed.
   # excludes = [ "/dev/pass6" ]

   ## Optionally specify devices and device type, if unset
   ## a scan (smartctl --scan and smartctl --scan -d nvme) for S.M.A.R.T. devices will be done
   ## and all found will be included except for the excluded in excludes.
   # devices = [ "/dev/ada0 -d atacam", "/dev/nvme0"]
   devices = [ "/dev/sda -d aacraid,0,0,0", "/dev/sda -d aacraid,0,0,1", "/dev/sda -d aacraid,0,0,2", "/dev/sda -d aacraid,0,0,3", "/dev/csmi1,2", "/dev/csmi1,3"]

   ## Timeout for the cli command to complete.
   timeout = "30s"

System info:

Windows Server 2019
smartctl 7.2 2020-12-30 r5155 [x86_64-w64-mingw32-2019] (sf-7.2-1)
Adaptec RAID 2405 ( 4 drive with RAID 0 )

Steps to reproduce:

Run telegraf: ( powershell ) with above smart config:
& 'C:\Program Files\telegraf\telegraf.exe' --test --debug --input-filter smart

Expected behavior:

smart_device,device=sda,enabled=Enabled,host=gcf-server-b,model=WD5000AAKX-0,power=ACTIVE,serial_no=WD-WMAYUW891053 exit_status=0i,health_ok=true,temp_c=0i 1624436434000000000

Actual behavior:

smart_device,device=sda,host=gcf-server-b exit_status=2i 1624435449000000000
smart_device,device=sda,host=gcf-server-b exit_status=2i 1624435449000000000

Additional info:

The problem is that function getAttributes from smart.go file use asynchronous call of function gatherDisk. Unfortunately parallel access to raid controller causes errors, end the only way to get it work as point in "Actual behavior" is to remove completely async functionlity from getAttributes ( smart.go ).

Seems that for now you can find workaround here: #8684
