CPU temperature collectd report on NetBSD
by Emile `iMil' Heitor - 2017-01-22
pkgsrc’s collectd does not support the thermal plugin, so in order to publish thermal information I had to use the exec plugin:
LoadPlugin exec
# more plugins
<Plugin exec>
Exec "nobody:nogroup" "/home/imil/bin/temp.sh"
</Plugin>
And write this simple script that reads CPUs temperature from NetBSD’s envstat command:
$ cat bin/temp.sh
#!/bin/sh
hostname=$(hostname)
interval=10
while :
do
envstat|awk '/cpu[0-9]/ {printf "%s %s\n",$1,$3}'|while read c t
do
echo "PUTVAL ${hostname}/temperature/temperature-zone${c#cpu} interval=${interval} N:${t%%.*}"
done
sleep ${interval}
done
I then send those values to an influxdb server:
LoadPlugin network
# ...
<Plugin network>
Server "192.168.1.5" "25826"
</Plugin>
And display them using grafana:
HTH!
