Cisco Temperature Monitor
Hi,
I am using Cisco 3750,3560,2960 and 1800 Series routers in my network. I want to see temperature graph of said equipment on NMS (OP Manager).
Kindly let me know that these devices support such snmp traps ? and how i see these devices temperature information on NMS.
Regards,
Arshad Ahmed
Please refer to, for example, the entries listed at the bottom of this post taken from the envmon MIB (full MIB at link I posted earlier).
I also confirmed a 3560, for example, will reporte its temperature via SNMP. The attached screenshot shows CiscoWorks LMS reporting a 3560G-24TS temperature graph (function similar to what you want to do with 3rd party NMS):
If you want to query directly from cli, that can be done as well. For instance:
C:\Program Files (x86)\CSCOpx\objects\jt\bin>snmpwalk -c [community_string] -O s -v 2c [device_adress] 1.3.6.1.4.1.9.9.13.1.3.1.3
iso.3.6.1.4.1.9.9.13.1.3.1.3.1005 = Gauge32: 40
Tells me the Cisco 3560 device queried in the screenshot above has a temperature of 40 degrees C.
I got the OID values to translate the entries below into numeric form used in the CLI query above from this table.

1130AG temperature monitoring (SNMP / MIB)
Hi
Im trying to get some SNMP monitoring running for multiple 1130AG APs. I keep running into walls though. APS are running with the following image : c1130-k9w7-mx.124-25d.JA1.
Problem 1.
I cant use the show environment cmd on the APs. According to the following official Cisco document, the show environment cmd is supported from image version 12.2(11) JA , but is not available on my APs running 12.4(25d)JA1:
http://www.csd.uoc.gr/~hy435/material/cr12425d.pdf
Problem 2.
According to the Cisco IOS MIB locator, the 1130AG AP does not support the ENVMON-MIB . That MIB is generally used for temperatur monitoring on many cisco devices. The 1130AG does however support ENTITY-MIB , but I am not entirely sure that this MIB can return temp info. There is very little/no documentation on this.
Can anyone help me out? I would very much appreciate it :)

With this monitor, you can have 2 analog outputs that you can transfer to the computer by using DAQ boards. In my case, I need temperature measurements at 3 different locations so I need 3 analog outputs, which is not possible with this device.
However, the monitor can also store temperature data in its memory and print the data. What I need is not to print the data but send the data to the computer somehow in digital form and postprocess it. I am using the "serial I/O" port to connect the device to the computer. I think I can do some configurations on the temperature monitor with the drivers in the link (http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=0241DD1B3AAF0341E0440003BA7CCD... ) but I am not sure if the device recognize the commands that I send through the I/O port.
Any advice on how to transfer (in digital form) the stored data on the monitor to the computer?http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=0241DD1B3AAF0341E0440003BA7CCD...
and the temperature monitor is the one in this link: http://www.lakeshore.com/products/cryogenic-temperature-monitors/model-218/Pages/Overview.aspx
Actually, it says in the manual that the stored data can be send to either printer or they can be retrieved by the computer interface. However, there is not enough information about how to perform this task.
I am using labview to read the data for the analog outputs and the drivers in the first link are also in labview language. But with those drivers, I cannot retrieve the data to the computer.
I will check MAX to test the communication with the device, though. Thanks for the advice! -
Good Temperature Monitor for C2D MBP??
Just got my 17" MBP and it's great!!
I am new to the laptop world, so if someone can recommend a temperature monitor (preferably free) that would be great.
It seems fine, but I'd like to be able to monitor this.
CheersIt may actually be overkill......
But this is the best one I have found:

Temperature Monitor for OS 10.3.9
I need an application or console command that will show me the temperature of my CPU.
I'm running a Beige G3 that is using a G4 processor. It's running OS 10.3.9 through the use of the application xPostFacto. I've found the apps "Temperature Monitor 4.8" and "Hardware Monitor 4.8," but those don't support any Mac OSs below 10.4.x. Temperature Monitor 4.7 supports Mac OS 10.3.9, but I can't find a download of it for the life of me. All of the links redirect to version 4.8.
Please, any help would be much appreciated, my project is at a stand still until I can find something that works.
Thanks!Click on my TMM name at left & send me an email. I'll send you the 10.3 version. Don't know if your Mac has the sensors to monitor the temps.

Temperature Monitor Alert:Memory controller heatsink Results!!!
Hello all...
I have a question about the Memory Controller Heatsink sensor in the temparature monitor and I would appreciate it if you could shed any light in my problem.
Well it was long time since I checked my temperatures on my G5 DP 2.3 so yesterday while I was into some MP3 encoding I heard the fans making alot of noise ,not something unbearable but not the usual silence behaviour I was used to even under heavy load and with the nap off.
So because of that noise I decide to check it with the temperature monitor but nothing unusual came up except...yes you guess it the Memory Controller heatsink.
An alert came up and inform me that the temp was over 75 C/167 F.
The threshold was by default at 75 C/167 F.
Let me add that it's summer here and a hot one at 37 C and the room is not airconditioning,but it was exactly the same one year ago(June 2005)and I never came up with an alert.
Also I have no problem with the rest indications.
So what do you think is it normal or may I have a broken fan?
And finally what is the Memory Controller Heatsink?
Thanx in advance!The memory controller heatsink is shown, with the associated cooling tubes and fins, in the right-hand photo of the 'back' of the main logic board here
http://homepage.mac.com/jerrycube/jerrycubepix/22601bluebord.jpg
Air is pulled over the back of the main logic board and through the cooling fins, by the fan in a plastic housing, at 90deg to all the other fans, behind the hard drives.
This fan is called "Main Logic Board Backside" by Hardware Monitor in this ancient DP2.0 - and is showing "20%" in 22deg C room temperature. "Memory Controller Heatsink" is at 54deg C.
37deg C is above the specified max. 'Operating Temperature' of 35deg C shown here
http://support.apple.com/specs/powermac/PowerMac_G5_Late2005.html
I think it would probably be advisable to find some way of lowering the temperature of the room the G5 is in... -
temperature monitor lite has detected the SMART sensor on my 1.83 mbp... can anyone tell me what temperature range is "normal" for my machine?
thanks in advance.
MacBook Pro Mac OS X (10.4.6)i know the whole heat thing has been done to death, but i was still hoping somone would humor me. i couldn't find a "normal" range listed in any other thread, or i wouldn't have posted.
and actually, sadly, my mbp isn't running just fine. among other issues, when it runs hot, my fan spins up and then down right away... i know, i know... the infamous "moo" has also been done to death. but before i send my machine away for service for two weeks (two weeks! an eternity) i thought a comparison with other users' experiences would be prudent...

New MacPro: Good temperature Monitor Application for the nMP?
Can anyone suggest a good temperature monitoring application they have used for the new Mac Pro?
ThanksI would recommend iStat Menus (http://bjango.com/mac/istatmenus/). I switched to it when I got the Mac Pro 2013 because Hardware Monitor doesn't work with the new Mac Pro. It's pretty good, although the history is only visual with graphs showing the evolution of the different sensors temperature. With Harware Monitor it was possible to read the temperature that were recorded at a certain point in time.

Best Temperature Monitoring Program?
Hey all, first time posting in the forums.
I recently got a mid-2012 MBP for college, so of course I immediately began putting games like Borderlands and GTA:SA on it. It runs anything I throw at it beautifully, but it gets awfully hot while it does. I know this is common for MBP's, even up to 90 degrees celsius, but it is something a tad worrisome when it gets over 80 (some games get it there every time....). So I've been trying to monitor it to at least be sure I'm not letting it get up there too often or for too long.
So had a few questions about temperature monitoring with Macs. I've currently got 3 programs running monitor temperature and system usage- System Pal, iStat Pro, and SMCfancontrol (which I also kick up a bit when playing the more GPU intensive games). The problem is that all three show different temperatures. Right now SystemPal reads 41 degrees celsius, SMCfancontrol reads 49, and iStat Pro has temps between 30 and 42 degrees. Which one's right? Is there a more accurate/definitive program for temp monitoring?
If it makes any difference, I usually play projected onto a 32 in LG TV using a thunderbolt to HDMI. I know this is more GPU intensive to begin with, but after going HD it feels a necessary evil.
If anyone happens to know of ways to keep temps down while gaming, monitor temps during full screen apps/games, or ways to monitor GPU usage (right now I have none ) I'd greatly appreciate advice on that too!
Thanks so much for answers!Try iStat Menus 4.02 or Temperature Monitor 4.96 or Hardware Monitor 4.96.

Dear All,
I need to develope a room temperature monitoring system which will alert by send mails when the temperature goes high. I just wanted to know whether there is any such hardware in the market, together with java, I can acheive this. Any help will be greatly appretiated. Thanks in advance. You can also mail me to [email protected] Thanks once again.
Ramya.ramya1us,
Have a look at http://www.ibutton.com/ibuttons/thermochron.html and at http://ibutton.com.ibuttons/java.html . They seem to sell plenty of hardware and information on writing software to interface with it.
I know of someone who has bought some of their hardrware and created a user controllable WebCam with it.
Hope this helps.

Internal temperature monitoring utility?
Is there any monitoring software (similar to Activity Monitor) that detects whether key components such as the CPU and hard-drive are running at a reasonable temperature or are overheating?
I believe that temperature-monitoring sensors are present inside the casing so in theory what I am asking about should be possible.Hi, KDS-KDS. My experience has been that temperature-reporting utilities such as the one linked by roam above (which I've tested) are only able to find a single sensor in my Tibook, the same generation as yours. That sensor watches only the hard drive, which is normally one of the cooler parts of a Tibook. Though there clearly are additional sensors in the machine, it appears that their output is unavailable to (or perhaps isn't readable by) such reporting software, for some reason. Owners of other Mac models have reported quite varied results, from highly satisfactory (several sensors detected) to no sensors detected at all.
This question came up several times in the Tibook discussion forums a while back, and my recollection is that no Tibook owner, regardless of which of the four generations his machine belonged to, ever found any temp-reporting software that could provide a readout on the CPU. If you do find one, please post in over there and let us know. -
Temperature monitoring for Core i3 CPUs
I have a i3 330M and lm-sensors results in nothing. Any ideas?
I've dug up some more info..
For temperature monitoring, a QST SDK is needed for supporting the ICH8 southbridge. The OpenAMT project is working on that (http://www.openamt.org/), but there doesn't seem to be much progess.
However, it looks like Intel will be releasing an SDK itself. See: http://software.intel.com/en-us/forums/ … hp?t=54851
Maybe after that we will have temperature & voltage monitoring support for all Nehalem and Arrandale chipsets. -
Where are temperature monitoring components on K9N Platinum?
Where are temperature monitoring components on K9N Platinum?
Ok it appears that with current systems there is no mbrd mounted CPU temperature thermistor. There are two thermal sensors inside a K8 CPU: one is a simple thermal diode for use by external circuitry, e.g. a hardware monitor or Super I/O chip and this is the temperature you will see as measured through that monitor chip; the second is used internally by the CPU for software and hardware thermal management so includes the circuitry to translate to a temperature reading. This second sensor is associated with the THERMTRIP Status register where the diode measured "current temperature" is stored in bits 23-16 (23-14 for Rev G); now in pre-Rev F CPUs that field is documented as "reserved" but it does appear to have the temperature stored in it since Speedfan reads it and reports a valid(-looking) temperature. So with Speedfan you can get two CPU temperatures reported which behave somewhat differently, probably due to different calibrations of the sensor circuitry. One is read through the hardware monitor chip; the other is read directly from a CPU register.
What I'd like to know is if there is anything at all under the CoreCell box? In my system it is certainly not the Winbond hardware monitoring chip which is clearly visible in another area of the mbrd. Does anyone have a dead mbrd they could rip the CoreCell box off, just so we know what is hidden there? -
Is my temperature monitor working correctly?
i've downloaded the marcel bresink temperature monitor for my macbook.
before the firmware update, it ran at 67 degrees celsius. after the firmware update, it runs at 40's.
when i restarted my computer few hours later, and loaded up the temperature monitor, it gave me a reading of 29 degrees and even with intensive work (where i can feel the heat and the fan working) the temperature monitor still remained at 29 degrees. right now, it seems to be stuck on 25 degrees. i've changed the preferences so that the sensors are updating the temperatures regularly. i've also tried reinstalling it. is there something wrong or am i not noticing something here?
thanks guy!
btw, my new macbook is working great!It's an Intel processor design fault. I got this info from the Hardware Monitor developer.
Q: I have a Mac with an Intel Core Solo or Core Duo processor.
Sometimes, the temperature readings seems to "hang" and are no longer
being refreshed. Is this a problem with the application?
A: No, this problem is caused by an internal design flaw of current
versions of Intel Core processors. The Digital Thermal Sensors may
stop working when the processor returns from a C3/C4 power saving
state. Intel plans to correct this hardware bug for future steppings
of the CPU.
Intel refers to this hardware problem as Erratum AE18. For detailed
information, please see Intel document 30922204
