Can't check logs

Hello,

In some instances, when I click on “Log” I receive this error:
"Some ad-block extensions are known to filter the '/log?id=' URL"
and, down on the right, appears this message:
"It appears there was a server exception. Please check server's log".

In file /var/log/one/oned.log appears these message:

Fri Nov 20 10:03:40 2020 [Z0][ReM][D]: Req:4112 UID:0 IP:127.0.0.1 one.vm.info invoked , 5682, false
Fri Nov 20 10:03:40 2020 [Z0][ReM][D]: Req:4112 UID:0 one.vm.info result SUCCESS, “5682<UI…”

And in /var/log/one/sunstone.log appears:

Fri Nov 20 10:03:40 2020 [I]: 192.168.10.25 - - [20/Nov/2020:10:03:40 +0100] "GET /vm/5682/log?id=5682&csrftoken=842835bc04ce673bff74995494b67b87661ae0700263da5096c73e9f833629d7 " 500 - 0.4060

These error is appearing with differents templates and not always…

Thanks.

(I’m using Passenger because Sunstone daemon fell some time to time)

Any idea?

Thanks.

Hi,

after some tests, I have discovered the problem. This is caused by a message in Spanish that contains a word with accents (“Operación”) when user tries to attach a IDE volatil disk… and, of course, system locales are defined as “es_ES@utf-8” (and, as I told yesterday, system is running Passenger RackApp). After changing locales to en_GB@utf-8, message returned during attaching an IDE volaltil disk, has not yet contains an accent.

If you have an VM with the same problem, you can remove the line with accents in /var/log/one/$id.log and you could get its logs again.

Bye!
