in_cpu or in_head: add cpu temperature?

[mahdi-asadpour-rr]

CPU temperature is reported in "/sys/class/thermal/thermal_zone0/temp" (Linux), which is an important metric to monitor in embedded systems. Would it be possible to include this somehow?

• include temperature in the in_cpu, OR

• it's actually possible to use in_head on this file, but the read value is outputted as "string" and not "number", which makes it not usable to visualize in Kibana when output_es is used.

Thanks.

Actually reading from a file will be considered as a string. No workaround at the moment but I will flag this issue as an enhancement request to see how this can be accomplished in the future.

@nokute78 what about an option on in_head to force a atoll() over the read data ?

[nokute78]

@edsiper In my opinion, it will be nice to support "types" feature of parser like fluentd.

Because type casting is helpful for not only in_head but also other input plugins.

[edsiper]

@nokute78 so for Parsers context it would be to add a new format(ter) backend-type, e.g:

• Regex
• JSON
• Number (handle integer and double)

I pushed #310 to update parser.

@edsiper It is different from parser of fluentd.
Could you check this?

@nokute78 I can confirm that #310 -- adding types -- solves the issue/feature mentioned here.

@mahdi-asadpour-rr
Thank you for reporting.

@edsiper Could you review #310 ?

[edsiper]

@nokute78 sure, shortly (~tomorrow)
