site query broken in web UI

[clelange]

I was trying to figure out if a data set is already available at a site, but the query

'site dataset=/DYJetsToLL_0J_TuneCP5_13TeV-amcatnloFXFX-pythia8/RunIISummer20UL16NanoAODAPVv9-106X_mcRun2_asymptotic_preVFP_v11-v1/NANOAODSIM'

equivalent to
https://cmsweb.cern.ch/das/request?instance=prod/global&input=site+dataset%3D%2FDYJetsToLL_0J_TuneCP5_13TeV-amcatnloFXFX-pythia8%2FRunIISummer20UL16NanoAODAPVv9-106X_mcRun2_asymptotic_preVFP_v11-v1%2FNANOAODSIM

returns

while dasgoclient lists the sites:

dasgoclient -query 'site dataset=/DYJetsToLL_0J_TuneCP5_13TeV-amcatnloFXFX-pythia8/RunIISummer20UL16NanoAODAPVv9-106X_mcRun2_asymptotic_preVFP_v11-v1/NANOAODSIM'

Any idea what could be wrong?

Clemens, thanks for report, it seems you found a bug in DAS web interface. The issue comes from calculation of ratios and in this case a dataset/blocks has zero files which cause to lead to NaN and web server fails to proceed. I identified the issue and send a patch in this commit: 5be4186 I need some time to perform additional tests to put version in production though and it may take a while since I'm traveling.

Thanks, Valentin! I'll wait for the fixed version to be deployed.

also, I found that any site queries on DAS web UI are broken now due to wrong proxy cert, see discussion here https://mattermost.web.cern.ch/cms-o-and-c/channels/web-serv--security

Now, the certificate issue is fixed and new version of DAS server is deployed, if you'll query DAS on cmsweb again you'll see the site content. Please verify and close the issue.

Thanks a lot! I can confirm it's working now (showing only the first 4 sites):

I haven't checked if the percentages are correct though. I assume they are.
