Hobbit compatible temperature monitor 🔗 link

I am looking to add temperature graphs to hobbit.

What should I use to monitor and graph the temperature of our server room?
None of our servers report any temperature readings in the client data.
We have some APC battery backups that have environmental monitors built 
in, but I am willing to spend a little cash on a separate device if 
there is something proven to work with Hobbit.

Thanks,

-Eric

We use ITWatchdogs Weathergoose.  I poll them with mrtg, and inject status information into hobbit using bbmrtg.pl

What servers are these? Any recent HP or Dell servers, if you have their respective agents (HPASM or OMSA) installed, should allow you to monitor their temperatures via snmp, e.g. with Devmon + Hobbit you should be able to get graphs for each temperature probe.

Can you get the temperature data via SNMP? The existing templates for APC devices in devmon don't have any 'temp' test, but if the data is there that can be fixed.

I'm using OneWire DS18S20 sensors from Maxim-IC.com to watch room and
refrigerator temps in my wife's dairy at home.  Right now it's a bit of a
hack, with the sensors just soldered onto old phone cables, but it works
just fine.  The fridge seems to be maintaining about 25F while the room temp
gets up over 85F.

I'm using digitemp to read the sensors, which can be hooked up to either USB
or serial ports, though it's also possible to use owfs.  The readings are
fed to Hobbit via a custom script that generates NCV compatible data for
graphing.

The bare sensors are about $5, and the USB or serial port connector is
around $30.  You can use any old ethernet or phone cable.

If your platform supports it you can use ipmitool for various internals.
Actual server room temp would need some external device such as the ones others have mentioned.

Example:
On a Sun X4150 box one of the sensors is Ambient Temp0. temp="`/usr/sfw/bin/ipmitool sensor reading 'Ambient Temp0' | awk '{print $NF}'`"

Other hardware has different sensor names, some just have (temp) sensors for CPU die temps.

We have a NetBotz appliance from APC which supports temperature probes.   I
use snmpwalk to query the MIB and produce a hobbit test which looks like:

            NetBotz Overall Status: normal(0)
          NetBotz Enclosure Status: normal(0)
                 Module Pod Status: normal(0)
                Location 1 Temp at: DC Temp. DCH2
            Location 1 Temp Status: normal(0)
           Location 1 Temperature : 76F
                Location 2 Temp at: Temp. East
            Location 2 Temp Status: normal(0)
           Location 2 Temperature : 70F
                Location 3 Temp at: Temp. West
            Location 3 Temp Status: normal(0)
           Location 3 Temperature : 77F
                   Humidity Status: normal(0)
                          Humidity: 34

I have never been able to get custom graphs working, so I am not graphing
the output. But getting custom graphs is not high on my priority list.

Well, devmon could be a convenient method to poll the device, and would make 
getting graphs and alerts quite easy.

It might be, but since it doesn't support snmp v3 I have not been able
to use it.  mrtg does support snmp v3, has templates, and bbmrtg.pl is
pretty stable for importing the states into hobbit.

I use some APC environmental monitors (model AP9319) and I have an external
script I'd be happy to provide to the community.

they seem to retail for about $200 now.

Stewart,
I'd love to see your script.
Have you set up graphing for it?

Yep.  We graph temperature and humidity (as that is the base sensor included
in the package).  just queried via SNMP.

Here you go!  all of our sensors are in climate controlled rooms, so
humidity is not a concern.  This reports them both on one page, but only
alerts if temp is out of range.  would be a trivial update if someone wanted
to alarm on humidity thresholds...

I have written many externals using this template.  I use the same model to
pull over 500 firewalls for 10 data points each in less than 30 seconds.

I'll leave the NCV stuff up to you. add an 'apctemp' test to your hosts and
off it goes! Have fun!
