logging output

[Athul Krishna]

Hi Manu,

I tried logging the output a script run through cloudprober using --log_dir.

But the output of the script is not gettng logged but other metric values are getting logged.

For example this is the output I get after running a sample script.

cloudprober 1558519385008376821 1558519393 labels=ptype=external,probe=testing,dst= success=4 total=4 latency=319124.706

cloudprober 1558519385008376822 1558519393 labels=ptype=external,probe=testing,dst= b=10.000 c=9.000 

cloudprober 1558519385008376823 1558519395 labels=ptype=sysvars,probe=sysvars hostname="host" start_timestamp="1558519385" version="undefined"

cloudprober 1558519385008376824 1558519395 labels=ptype=sysvars,probe=sysvars cpu_usage_msec=14.410

Here the first two lines are not getting logged.

Another thing is I was able to log everything when I used the binary version of cloudprober.

Is there a way to log it?

Regards,

Athul

We disabled logging by default in the latest cloudprober release. You can enable it back on a per probe basis using the log_metric field:

https://github.com/google/cloudprober/blob/6d530d843d2a584b857e199389e9765df984df8f/probes/proto/config.proto#L91

You'll need to add the following to your probe def:

probe {

  name: test

  type: EXTERNAL

  ..

  debug_options {

    log_metrics: true

  }

}

Reason for disabling log_metrics was the duplicate data. Same information is anyway sent to STDOUT by default, if you don't configure any surfacers.

You can add a file surfacer to your config, to send all metrics to a file:

surfacer {

  type: FILE

  file_surfacer {

    file_path: "/tmp/x/"

  }

}
