Hi all:
Whenever I have to maintain a PC, I look at GSmartControl (on Linux) or
CrystalDiskInfo (on Windows).
If any S.M.A.R.T. attributes are red or yellow, I know that something is
not quite right with the disk.
I would like Prometheus to automate this by generating alerts for SMART
warnings or errors.
I would have thought this to be a basic feature for such an advanced
monitoring system like Prometheus, but alas, I have found no easy solution
yet.
The Windows Exporter seems to deliver no such disk information, but the
Node Exporter for Linux/Unix does deliver SMART attributes like
"reallocated sector count":
# HELP smartmon_reallocated_sector_ct_raw_value SMART metric
reallocated_sector_ct_raw_value
# TYPE smartmon_reallocated_sector_ct_raw_value gauge
smartmon_reallocated_sector_ct_raw_value{disk="/dev/sda",smart_id="5",type="sat"}
0
# HELP smartmon_reallocated_sector_ct_threshold SMART metric
reallocated_sector_ct_threshold
# TYPE smartmon_reallocated_sector_ct_threshold gauge
smartmon_reallocated_sector_ct_threshold{disk="/dev/sda",smart_id="5",type="sat"}
36
# HELP smartmon_reallocated_sector_ct_value SMART metric
reallocated_sector_ct_value
# TYPE smartmon_reallocated_sector_ct_value gauge
smartmon_reallocated_sector_ct_value{disk="/dev/sda",smart_id="5",type="sat"}
100
# HELP smartmon_reallocated_sector_ct_worst SMART metric
reallocated_sector_ct_worst
# TYPE smartmon_reallocated_sector_ct_worst gauge
smartmon_reallocated_sector_ct_worst{disk="/dev/sda",smart_id="5",type="sat"}
100
I am no S.M.A.R.T. expert. Can anyone tell me how to generate alerts from
those values?
Or is there a better way? Any alternative for Microsoft Windows?
Thanks in advance,
rdiez
