Getting journalctl logs from landscape scripts

snap
1

Hey, we would like to retrieve device logs(journalctl) through landscape scripts, but journalctl requires sudo access, tried with root user too, is there a way to get logs without requiring root privileges.

Thanks in advance

Does the landscape-client snap not run as a daemon (i.e. as root) ? It should have full access to logs and the journalctl binary via the log-observe interface this way…

Its working as a daemon, but seems landscape-client doesnt have this interface

Ah, you should open an issue/bug for this then, so the interface gets added

5

Hey, @mikecw would it be possible to add log-observe interface into landscape-client ?

6

Yeah ok. I don’t see why not. I’ll sort it out.

PR done. It just needs to go through the usual checks, builds, testing, release cycle blah blah blah stuff.

You will need to manually connect the interface though.

8

thanks a lot, would you mind to notify, when its released into edge or sth, maybe any other way to track it.

9

Will this always be the case?

I guess we can connect through Landscape API itself :stuck_out_tongue:

10

Probably not - the interface will probably get auto-connected in the global snap store at some point although if you are using a dedicated snap store, you have the power to make that auto-connection yourself.

And yes - you technically could make the connection with a Landscape script…

11

The edge track now has the interface. Just manually add with

snap connect landscape-client:log-observe

Request made for auto connect: https://forum.snapcraft.io/t/auto-connect-of-log-observe-for-landscape-client

Thanks for update. Do you have estimate time to released as stable?

14

Not quite I am afraid. We’ve found a slight bug in the edge release with configurations that we just want to get fixed first so I’m afraid at the moment the answer is “not too long”.

Should be stable now.

Thank you very much! I’m hoping this auto-connection will be completed soon.

Best regards.
