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:
