perfSONAR User Q&A and Other Discussion

[Johann Hugo <>]

Hi

Latency tests are working fine by adding ?format=psconfig, but throughput tests gives a validation error: 

[root@ps-1-100g /]# psconfig validate https://155.232.195.41/pub/config/sanren_100g.json?format=psconfig
Loading template ...... OK
Validating JSON schema ...... OK
Verifying object references ...... OK
pScheduler Validation (Quick) ...... FAIL

Test spec SANReN 100g Throughput is invalid when used in task SANReN 100g Throughput:
    At /: Additional properties are not allowed ('streams' was unexpected)

It validates fine if I remove "streams": 2 from the config file by hand

    "SANReN 100g Throughput": {
      "type": "throughput",
      "spec": {
        "duration": "PT10S",
        "streams": 2,
        "source": "{% address[0] %}",
        "dest": "{% address[1] %}",
        "omit": "PT5S",
        "ip-version": 4,
        "schema": 1
      }
    }
  },

PWA should be the latest version. I did a docker-compose pull to make sure.

The perfSONAR testpoint is a docker container, based on Centos 7 (testpoint:v5.0.8)

BTW, I see the same issue with my very old PWA server when I add ?format=psconfig to the URL.

This works fine:

psconfig validate https://perf-pwa.sanren.ac.za/pub/config/sanren_100g.json

This gives the same validation error:

psconfig validate https://perf-pwa.sanren.ac.za/pub/config/sanren_100g.json?format=psconfig

Thanks a lot. It's working fine now.

Hi,

That seems to be an old version of PWA that returns the a format that is no longer supported and a pre-5.1.0 version of "psconfig validate". I get a slightly different error when I validate using the latest “psconfig validate”, but I suspect the old format is the cause:

# psconfig validate "https://155.232.195.41/pub/config/sanren_100g.json"

Loading config ...... OK

Validating JSON schema ...... FAIL

    Error: Additional properties are not allowed ('organizations', 'measurement_archives', 'description' were unexpected)

If you change the URL to "https://155.232.195.41/pub/config/sanren_100g.json?format=psconfig” then it will validate. 

Hope that helps,

Andy

Hi all

I'm trying out the latest PWA tool, but I get the following error when I validate the file:

psconfig validate https://155.232.195.41/pub/config/sanren_100g.json
Loading template ...... FAIL

Error retrieving JSON. Encountered the following error:

   No task objects returned.

What does this error mean? 

Is there something missing in my configs?  

See attached screenshot of configuration + json file that was generated.

Regards

Johann
