Fuel UI does not show old ironic-conductor logs

[Kyrylo Romanenko]

1. Having MOS cluster with Ironic working last 3 days.
2. When tried to read previous warnings and errors of Ironic node in conductor logs
http://<FUEL_IP>:8000/#cluster/1/logs/type:remote;node:3;source:os/ironic-conductor;level:warning
i noticed that i can not see via UI only fresh messages for the last day.

3. root@node-3:/var/log/ironic# ls
ironic-conductor.log
ironic-conductor.log.1

Only logs from "ironic-conductor.log " are accessible via UI.

Expected to see older records like for nova-compute logs, where Fuel UI show records from rotated logs and even from compressed ones. Example:
root@node-2:/var/log/nova# ls
nova-compute.log nova-compute.log.1 nova-compute.log.2.gz nova-manage.log

Record from compressed nova-compute.log.2.gz were visible in UI and found in GZ archive by zgrep:
zgrep req-84b2e0df-e317-4d72-b16d-164a3b5fa3a6 nova-compute.log.2.gz
Attached screenshot where this record available in UI.

[Dmitry Pyzhov (dpyzhov)]

Rotated logs are hidden from UI by design. Sorry, but we are not changing this behaviour because we deprecating UI logs.
