[network::dell::os10::snmp::plugin] bad fan status

[jeremyit]

Hi, I use OS10 centreon plugin to check Dell S4112 hardware status. Works fine on standard airflow. S4112 with reverse airflow fans plugin give a bad status in result of check. I think because hardware fan count is false.

Reverse airflow switch, output plugin :

UNKNOWN: fan '1' status is 'unknown' - fan '2' status is 'unknown'
'TH04Y1xxxxHDN45O123#hardware.temperature.celsius'=55C;;;; 'hardware.card.count'=1;;;; 'hardware.fan.count'=5;;;; 'hardware.fantray.count'=1;;;; 'hardware.psu.count'=2;;;; 'hardware.temperature.count'=1;;;;

output show system command on switch :
OS10#Show system
-- Fan Status --
FanTray  Status      AirFlow   Fan  Speed(rpm)  Status
----------------------------------------------------------------
1        up          REVERSE   1    11531       up
                               2    11464       up
                               3    11430       up

Standard flow switch, output plugin :

OK: All 8 components are ok [1/1 cards, 3/3 fans, 1/1 fantray, 2/2 psus, 1/1 temperatures].

                               3    11364       up

To fix quickly monitoring I had to add: --filter=fan,1 --filter=fan,2 but I lost fantray

OK: All 7 components are ok [1/1 cards, 3/3 fans, 2/2 psus, 1/1 temperatures]. | 'TH0xxxxEHDNxxxx#hardware.temperature.celsius'=55C;;;; 'hardware.card.count'=1;;;; 'hardware.fan.count'=3;;;; 'hardware.psu.count'=2;;;; 'hardware.temperature.count'=1;;;;

Hello :)

Can you provide us with the output with the --debug option? And ideally a SNMPWalk from your equipment (anonymized) which would allow us to reproduce the situation internally and work on it?

Hello Lucie :) Thanks for reply.

First the --debug output, and then I attached the snmpwalk output.
