hddtemp sensors not updating correctly

[tsumaru720]

Hi Fellas,

I noticed that last Thursday, graphs for my hddtemps are not displaying correctly in LibreNMS

My daily.sh cron runs at 00:15 every day which is about the time this seems to have occured (as per the graph)

As per request from @laf on IRC - Output of (snipped ofc):

./poller.php -r -f -m applications,unix-agent -h HOSTNAME -d

http://pastebin.com/y7sCfhK7

Permissions appear to be correct (and the files are being updated, by rrdcache) however it seems zero value is being inserted into the RRDs themselves - no other issues with RRD files as far as I can tell

As evident by the paste, the temps seem to be exposed correctly to LibreNMS

@laf Looks to still be inserting 0's into RRDs.
Ran poller manually

./poller.php -h HOSTNAME -d

Maybe my PR #5930 fixes this?

[tsumaru720]

Looking at comments on #5930 which suggests this is fixed so I updated from 872eac1 to 1140be1 and it does seem to be working again
