I'm trying to enable sysstat to take temperature readings, so that I have past temperature information to diagnose host failures in the future.
I tried this command to get temperature information:
$ sar -m TEMP
Requested activities not available in file /var/log/sysstat/sa22
Here's what the sar man page has to say about this:
-m { keyword [,...] | ALL }
Report power management statistics. Note that these statistics depend on sadc's option "-S POWER" to
be collected.
Possible keywords are CPU, FAN, FREQ, IN, TEMP and USB.
[...]
With the TEMP keyword, statistics about devices temperature are reported. The following values are
displayed:
According to this, power management information (which temperature is a subset of) is not logged by default. So, I changed the file /etc/sysstat/sysstat
to enable it. I changed this:
# Parameters for the system activity data collector (see sadc(8) manual page)
# which are used for the generation of log files.
# By default contains the `-S DISK' option responsible for generating disk
# statisitcs. Use `-S XALL' to collect all available statistics.
SADC_OPTIONS="-S DISK"
into this:
SADC_OPTIONS="-S DISK,POWER"
Another issue on the [sysstat issue tracker](https://github.com/sysstat/sysstat/issues/156) said that sysstat requires lm-sensors to function, so I installed that package too. Here's the output of sensors
:
$ sensors
acpitz-acpi-0
Adapter: ACPI interface
temp1: +27.8°C (crit = +119.0°C)
temp2: +29.8°C (crit = +119.0°C)
coretemp-isa-0000
Adapter: ISA adapter
Package id 0: +89.0°C (high = +82.0°C, crit = +100.0°C)
Core 0: +86.0°C (high = +82.0°C, crit = +100.0°C)
Core 1: +88.0°C (high = +82.0°C, crit = +100.0°C)
Core 2: +89.0°C (high = +82.0°C, crit = +100.0°C)
Core 3: +89.0°C (high = +82.0°C, crit = +100.0°C)
Core 4: +88.0°C (high = +82.0°C, crit = +100.0°C)
Core 5: +87.0°C (high = +82.0°C, crit = +100.0°C)
nvme-pci-0800
Adapter: PCI adapter
Composite: +38.9°C (low = -273.1°C, high = +84.8°C)
(crit = +84.8°C)
Sensor 1: +38.9°C (low = -273.1°C, high = +65261.8°C)
Sensor 2: +37.9°C (low = -273.1°C, high = +65261.8°C)
So this does seem to correctly detect my temperature sensors.
I also tried waiting ten minutes for another collection to happen. (My system is configured to log every ten minutes, at :05, :15, :25, etc.)
Unfortunately, after all that, I still get the same error:
$ sar -m TEMP
Requested activities not available in file /var/log/sysstat/sa22
