There are few discussions about the Topic; unfortunately, not with complete explanation.
Question addresses few issues.
At the Nexus 9000; list of temperature sensors are here:
Temperature:
--------------------------------------------------------------------
Module Sensor MajorThresh MinorThres CurTemp Status
(Celsius) (Celsius) (Celsius)
--------------------------------------------------------------------
1 FRONT 80 70 35 Ok
1 BACK 70 35 35 MinorAlarm
1 CPU 90 80 41 Ok
1 Bigsky 110 100 50 Ok
It's visible that the MinorThres has half of the value of MajorThres; which may partially causing the issue.
Then:
Fan:
---------------------------------------------------------------------------
Fan Model Hw Direction Status
---------------------------------------------------------------------------
Fan1(sys_fan1) NXA-FAN-160CFM-PE -- back-to-front Ok
Fan2(sys_fan2) NXA-FAN-160CFM-PE -- back-to-front Ok
Fan3(sys_fan3) NXA-FAN-160CFM-PE -- back-to-front Ok
Fan_in_PS1 -- -- back-to-front Ok
Fan_in_PS2 -- -- back-to-front Ok
Fan Zone Speed: Zone 1: 0xff
Shows fan direction. Here it's visible that it's back-to-front.
And, strange, the temperature at BACK is the same as at the FRONT; that may show that temperature at Room is already high.
What I wanted to ask is if applets at the Cisco Nexus 9000 may be used to configure existing numbers; in this case, the MinorThres number; to put there 39; for example (I checked the "history" of alert, the temperature is not going over 37 degrees Celsius).
If those numbers are hardcoded, it may not be possible (to reconfigure numbers using applets), at that case, is there any possibility to use applet to disable thise single one, exact sensor from monitoring?
Applets are described at few pages, unfortunately, very basic way and examples are basic, simplified as well.
I do not have saved applets
Command which shows that::
show event manager policy internal
Also, in global configuration mode, applet may be created:
event manager applet tempthre
event tempe modu 1 sens 2 thres minor
action 1 cli show environ temperature
end
And, prepared applet can be run.
This is just very basic, initial applet; just for having an example.
Again; question is if applet may change MinorThres value and / or it may exclude that row from being monitored?
Thanks a lot.
