[tempmon] Monitor temperature and take action if too high.

[af123]

It's been bothering me for a while that there is no easy way of telling if the internal fan has failed so I've written a new tempmon package which checks the HDD temperature every three minutes and can take action if it exceeds configurable thresholds.

The alert looks like this and also creates a notification which will be shown when logging into the web interface.

 

[Trev]

Brill. Is there no end to your Hummy skills?

 

[Wallace]

Just when you think it can't get any better...

Thanks af123.

Update:

I have install this on one of my HDRs to test. Set warnings t0 45/50/60. The actual HDD temp is 26 as the unit hasn't been on long.

The HDR gave a warning in the WebIF 'Temperature is 118 and exceeds standby threshold of 50'. The HDR shut off (standby).

When I powered it on, the WebIF reported '...box crashed, check Crash.log for info...'

Update, update:

I am stuck in a loop! Now when I turn the unit back on (front button), WebIF reports high temperature and puts the unit into standby again.
The unit does not even stay on long enough for me to disable the package.

HELP!

Update, update, update!

Wow, you have to be quick on the button, but I just managed to remove the tempmon package before it shut the unit down. All OK now.

I think I will wait for a package update! Just glad I didn't install it on the other HDR used by SWMBO!

 

[af123]

Ouch, sorry about that - worked fine on all three of my boxes!
I'll send you an update file to disable it. You'll need to put it on a USB stick and plug it in during boot.

Package removed from repository for the moment.

Tempmon doesn't seem to be available from the hummypkg i.e. :-

[Wallace]

Cross posted I think. I managed to remove it.

FWIW, the HDD is a WD 10EVDS as per 'HDR Green' in my sig.

 

[af123]

Package is http://hpkg.tv/hdrfoxt2/killtempmon.spk

 

[Wallace]

I don't mind being a Guinea pig to try an update if it helps.

Phew.

Could you run the tm diagnostic for me?

No problem, here is the result:

It worked OK on mine, but I had to reboot as the WI no l,onger responded. There were a couple of other updates as well, including the WI. Thinking about it, it probably wasn't tempmon as I had to install it after the reboot.
Anyway, set it to warn at 35 and sure enough it did when the temp got there, but on resetting the warning temp to 46 (well above its actual temp), the warning remained until a reboot. Is this by design? If so, how about making it auto reset when the temp drops below the warning threshold?

 

[Wallace]

I like to be different...

 

[prpr]

Don't ya wish SMART data was properly standardised...

 

[Ezra Pound]

I think the idea is to warn you of an O-M-G event, so you wouldn't want it to auto reset

 

[af123]

Oh yes, mine looks like:

194 Temperature_Celsius  -O---K  038  053  000  -  38 (0 17 0 0)

 

[af123]

No problem, here is the result:

Could you run the same diagnostic again please?

 

[Wallace]

Here you go...

Obviously, the unit has warmed up a bit now...

 

[af123]

New version available now!

 

[Wallace]

I have installed the update, retaining the original settings.

Stable so far

Thanks.

 

[af123]

The current temperature is displayed on the settings panel now too so you can check that it seems reasonable!
