perfSONAR User Q&A and Other Discussion

Hi Doug,

It sounds like you need to change the archiver definition in your central pSConfig JSON template file. I’m guessing it either does not have any archive definitions or it has an “http” archiver defined but does not contain the following to tell MaDDash where to get data in a format it understands:

"_meta": {

        "esmond_url": "https://example.archive/esmond/perfsonar/archive/"

    }

See the docs here for more details on generating the archive definition: https://docs.perfsonar.net/multi_ma_install.html#scenario-3-writing-to-a-remote-archive-with-ip-authentication 

If none of the above helps, send me the URL to the pSConfig json (i.e. the one you’d get from “psconfig remote list”) and I’ll see if I notice anything.

Thanks,

Andy

We’ve been upgrading all of our Measurement Hosts to Perfsonar 5.0.6. In conjunction with this we updated our Maddash implementation to 5.0.6 but after doing so the psconfig-maddash-agent can no longer successfully build a maddash.yaml file with the grids we had before the upgrade. A psconfig maddish-stats shows 0 grids:

]# psconfig maddash-stats

Agent Last Run Start Time: 2023/11/21 17:32:46

Agent Last Run End Time: 2023/11/21 17:32:49

Agent Last Run Log GUID: 0A619144-88D7-11EE-92C2-9548F7BB3364

Total grids managed by agent: 0

And the psconfig-maddash-agent.log shows warnings and errors we have not seen before:

Check the plugin requirements as well as any selectors you may have defined and verify they match your configuration.

Any input to point me in the right direction would be greatly appreciated.

Thanks, Doug.
