understand thermal check commands

fatboy1607 — Fri, 30 Jan 2015 05:52:50 GMT

Need help with understanding output for this.

show system state filter env.* | match thermal

env.s1.thermal.0: { 'alarm': False, 'avg': 55.000, 'desc': 6220 Core Temperature, 'hyst': 4.500, 'max': 95.000, 'min': 5.000, 'notified-avg': 55.000, 'samples': [ 55.000, 55.000, 55.000, ], 'shutdown': False, }

env.s1.thermal.1: { 'alarm': False, 'avg': 39.000, 'desc': System Temperature, 'hyst': 3.250, 'max': 70.000, 'min': 5.000, 'notified-avg': 41.333, 'samples': [ 39.000, 39.000, 39.000, ], 'shutdown': False, }

what does false mean

what is 6220 Core Temperature and system tempreature.

hyst

samples ?

shutdown false means if it will not shutdown false if temp reach max ?

thanks for help in advance.

Hello Mandar,

I hope, you took this CLI output from a PA-200 firewall. "false" mean, there are no alarm currently activated. If any incident/alarm is not active then the firewall will show as "false".

A PA-200 firewall is having one physical dual-core CPU, that represent through "6220 Core". For Example, if you apply the same command on a PA-3000 FW, you will be able to see CAVIUM, OCELOT, INTEL etc.

The average value will be calculated based on multiple sample(3 sample mostly) taken within a small time interval,

For your better understanding, ihave given an example of 2 CLI command 1. >show system state filter env.* | match thermal and >> show system environmentals

Hope this helps.

** Please mark my answer as correct/helpful if appropriate.**

Thanks

Hi Kulkarni,

False - I used for any kind of Alarm. In this case you can consider as "Alarm False" which means there is No Alarm. In case it turns True than "Alarm True", which means system has some issue.

"6220 Core" - is a dual core CPU

'samples': [ 55.000, 55.000, 55.000, ] - is a temperature samples, it should be always bellow 60, other wise "false" will be turn into "True", and its a temperature alarm.

I am not sure of "shutdown" word.

what does this represent shutdown': False, }

Hello Mandar,

"shutdown': False" represent that, there was no incident ( system shutdown) happened because of the thermal condition and the "Alarm=False".

Hope this will give you a better clarity.

Thanks

ok , what is difference between 6220 Core Temperature and System Temperature

I see pattern on one of our firewall were 6220 core tempreature is high 56 Degree but system temperature is normal 39 Degree

what does that say to us.

Thanks for help.

The core temperature is measured on the CPU, which is typically the source of heat whereas system temperature is measured elsewhere in the chassis. it is normal for the core temperature to be higher than the system temperature

how much is average temperature for 6220 Core Temperature we expect to see on firewall.

Re: understand thermal check commands

reaper — Wed, 04 May 2016 07:50:11 GMT

The average needs to be between the recommended operating temperatures (5 - 95) and will vary depending on your environment, room temperature (office desktop or AC serverroom) , amount of traffic (more traffic means more computational cycles means more heat) etc, so it is not possible to give a global average

I think I recall TAC telling me that each firewall platform has an upper temperature limit at which the firewall will shut itself down. Can anyone shed any more light on this?

But if it shutdown, it would be shutdown. Right? Maybe not for a chassis system where it's possible you could be connected to the MPC and it could tell you that one of the NPC or DPC cards shutdown due to overheating. But if the chassis itself or MPC overheats...

I am wondering if Shutdown:False instead refers to the system being set to shutdown upon a temperature threshold. Not sure if this is configuration.

In either case though... it's not clear at what temp the shutdown would happen. I assume that it's not the same as the alarm threshold.

+1 on needing to know the shutdown vs alarm threshold. Does the shutdown action need to be enabled, or is it just always there? At what temperature does the system shut itself down vs just fire an alarm?
