perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi Johann,

Looks like our docs and the helper script are putting that “_meta” field in the wrong place, sorry about that. Move _meta outside the “data” element and you should be good to go. Example:

{

    "archiver": "http",

    "data": {

        "schema": 2,

        "_url": "https://{% scheduled_by_address %}/logstash",

        "verify-ssl": false,

        "op": "put",

        "_headers": {

            "x-ps-observer": "{% scheduled_by_address %}",

            "content-type": "application/json", "Authorization":"Basic cGVyZnNvbmFyOmRMRE50dmt0Q253elZNdXRlbUdr"

        },

        "schema": 3,

        "_url": "https://perf-cm.sanren.ac.za/logstash",

        "verify-ssl": false,

        "op": "put",

        "_headers": {

            "x-ps-observer": "{% scheduled_by_address %}",

            "content-type": "application/json"

        }

    },

    "_meta": {

        "esmond_url": "https://perf-cm.sanren.ac.za/esmond/perfsonar/archive/"

    }

}

Thanks,

Andy

Looks like pscheduler keeps on running (pscheduler monitor shows green tests) when I merge the json into /etc/perfsonar/psconfig/archives.d/http_logstash.json

but psconfig-pscheduler-agent is complaining about invalid archiver data.

Test results are not posted to local or central logstash archives + errors for the local esmond archives. Pscheduler is complaining about Invalid JSON returned.

Any ideas ?

Hi Andy

I've tried both methods on one of my testpoints, but no luck.

1) Adding raw json to my PWA config:

 The testpoint downloads the config. "psconfig pscheduler-stats list" shows all the tests that it should run. I can see the tests under "pscheduler monitor", but all the tests are grey. See attached mesh config file created by PWA.

2) Create a  json archive file under /etc/perfsonar/psconfig/archives.d/

With my old mesh config file the tests under "pscheduler monitor" are green. When I create a json archive file under under /etc/perfsonar/psconfig/archives.d, then the tests under "pscheduler monitor" turn grey. When I delete the json archive file (attached perf-cm.json) it will go green again. 

I've added the IP of my own pc to /etc/httpd/conf.d/apache-logstash.conf on the central archive server and I can see it's waiting for test results when I open https://perf-cm.sanren.ac.za/logstash, but if I tail -F /var/log/httpd/ssl_access_log only esmond results are posted to the server, no logstash results.

Hi,

You would add that to the PWA archiver config. I don’t have a PWA interface in front of me, but I believe there is a way to add raw json to the archiver config, so you should be able to use that since there will not be pulldowns for all the options (a PWA refresh is a something we are looking at currently, but still quite a ways out). Alternatively, on the measurement hosts (i.e. the host running pscheduler and doing the actual measurements) you can add the JSON from that command into a .json file) under /etc/perfsonar/psconfig/archives.d. You can name the file whatever you want as long as it ends in .json.

Thanks,

Andy

Hi all

I'm trying to get a new central measurement archive running, using authentication by IP address:

https://docs.perfsonar.net/multi_ma_install.html

I've done the following:

- yum install perfsonar-archive

- vi /etc/httpd/conf.d/apache-logstash.conf 

     Require ip 155.232.40.0/24

- /usr/lib/perfsonar/archive/perfsonar-scripts/psconfig_archive.sh -a none -n perf-cm.sanren.ac.za

{
    "archiver": "http",
    "data": {
        "schema": 3,
        "_url": "https://perf-cm.sanren.ac.za/logstash",
        "verify-ssl": false,
        "op": "put",
        "_headers": {
            "x-ps-observer": "{% scheduled_by_address %}",
            "content-type": "application/json"
        },
        "_meta": {
            "esmond_url": "https://perf-cm.sanren.ac.za/esmond/perfsonar/archive/"
        }
    }
}

According to the docs, this is the next step:

Copy above to your central pSConfig template and your measurement hosts should begin archiving

I'm not sure what or how I should do this. Should I add it somewhere to the PWA json config file that the measurement hosts download, or somewhere on my archive/MadDash server ?

Regards

Johann
