eos exporter exit status 194

Dear EOS experts,

we have deployed eos_exporter for the EOS instance fmfi (the exporter
listens on :9986). The exporter starts correctly, but multiple
collectors consistently fail during metrics collection with errors such as:

failed collecting space metrics: exit status 194
failed collecting node metrics: exit status 194
failed collecting fs metrics: exit status 194
failed collecting ns metrics: exit status 194
failed collecting fsck metrics: exit status 194
failed collecting eos inspector metrics …: exit status 194

At the same time, the MGM log (/eos/xrdlog.log) shows the following
server-side error:
Unable to execute proc command - you don’t have the requested
permissions for that operation (2) /proc/admin/; Operation not permitted
sec=unix uid=65534 gid=65534 unit=mgm@lcgeos.dnp.fmph.uniba.sk:1094

What is confusing for us is that manual eos CLI commands work fine when
executed interactively.

Environment details
Operating system:AlmaLinux 9.3
EOS version: EOS_INSTANCE=eosdev
EOS_SERVER_VERSION=5.3.27 EOS_SERVER_RELEASE=1
EOS_CLIENT_VERSION=5.3.27 EOS_CLIENT_RELEASE=1

Thank you very much for your help.

Best regards, Michal Meres

Hi @mmeres !
Under which user is the exporter running? It seams that that user does not have the required permissions on EOS. If the exporter is running under a systemd unit, make sure that User field is correct in Service section.

Cheers,
