"Disk drive temperatures and health" graphs empty

[mgruben]

"forked" from issue 91.

In summary, I'm able to # hddtemp /dev/sda and to # smartctl -a /dev/sda and return Celsius temperatures for that SSD, but the Monitorix graph for Disk Drive Temperatures has only -nan values.

This time, however, -nan occurs regardless of whether with rrdtool branch 1.4 or branch 1.5.

Added copy of the disk.rrd log file to my host, http://76.209.20.97:9997/

OK, after checking your log file I see the following lines right after starting Monitorix:

Mon May 18 07:08:17 2015 - Loaded main configuration file '/etc/monitorix/monitorix.conf'.
Use of uninitialized value in lc at /usr/lib/monitorix/disk.pm line 60.

Mon May 18 07:08:17 2015 - disk::disk_init: 'accept_invalid_disk' option is not set.
Mon May 18 07:08:18 2015 - fs::fs_init: Unable to detect the device name of '/mnt/4TB'. I/O stats for this filesystem won't be shown in graph. If this is really a mount point then consider using <devmap> to map it manually to a device name.

Can you, please, paste the sections <disk> and <fs> from your configuration file? Thanks.

On occasion I have one or more external hard drives plugged in, which become /dev/sdb and /dev/sdc respectively, and one of which is occasionally mounted to /mnt/4TB

If you configure a device name that won't be permanent in the system, then you must set the option accept_invalid_disk to y in the configuration file.

Please, read the monitorix.conf(5) man page. Thanks.
