temperature

Hi,

I have searched sam, stm and various env files and I have been as yet unsuccessful in finding the current temperature of a machine.

Can anyone tell me how to find out the temp of a Unix server.

Re: temperature

Hi,

What is server model?

If you can login thr. GSP do following pro

GSP>ps
PS

Power Monitor Status:
Firmware Revision : 3
System Power state: On Power Switch : On
Temperature : Normal Selected fan state: Normal

Power supplies | Fan
# State Type | States
-----------------------------------------------------------
0 Normal Type 0 | Normal
1 Normal Type 0 |

above o/p u will find temp is normal

Re: temperature

Hi,

There are rp7410's which use MP as opposed to GSP but there are also L-classes that use GSP. I have actually obtained this info also however I was really looking for something more specific than 'NORMAL', i.e. the actual temp in degrees?

Cheers,
Dermot

Hi Dermot,

Check this doc.

Re: temperature

V class servers have something as env command. That used to give exact temp. of the system. But on other systems PS is what you can come close to.

Re: temperature

Hiya Dermot

If you are interested in the temperature of the environment (which has a bearing on the machine temperature), as an alternative you could use STM to report the temperature of connected disk enclosures instead (assuming they're in the same rack). I've suceeded in this with DS2300s and SC10s.

Sorry if this doesn't help, I've been in the same situation as yourself and nothing appears to be available!!

Re: temperature

By far the best (and most universal) way to do this is to use an instrument designed for this purpose. It's called a thermometer. You really should have a digital thermometer equipped with a data port and then this becomes trivially easy. I've used inexpensive models manufactured by ExTech; these come with mutiple thermocouples and a serial port so that measurements can be made at various locations in the DataCenter simultaneously. It's very easy then to write a monitor program to sample this data.
If it ain't broke, I can fix that.

Re: temperature

A Clay - got a web site or reference point(s) for both purchase and code? You caught my eye with the whole idea of multiple sensors in the room - instead of just one per room. I'd also like to be able to program more handling options myself than just use "whatever the system comes with". Thanks ...

Re: temperature

Hi Dermot,

on a r[p|x][7|8]xx machines you can connect to the mp and try these commands from the MP:


MP> cm


Enter HE to get a list of available commands



MP:CM> de

B - BPS (Bulk Power Supplies)
U - CLU (Cabinet Utilities: Fans, Intrusion, Clock's etc.)

The "Inlet Air temperature" is exactly what you are looking for.

Stefan,

Thanks a million! This is exactly what I was looking for.

Re: temperature

As Stefan outlined in his mail, this I believe is the only means of obtaining exact server temp info.
