For example, after installing lnav,
sudo snap install lnav
sudo snap connect juju-lnav:juju-bin juju
running
juju-lnav octavia:/var/log/octavia/*.log{,1}
will open the current and the first rotated log files from all of the octavia units.
Likewise

nova-cloud-controller:/var/log/nova

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
If you’re running Ubuntu 16.04 LTS (Xenial Xerus) or later, including Ubuntu 18.04 LTS (Bionic Beaver) and Ubuntu 20.04 LTS (Focal Fossa), you don’t need to do anything. Snap is already installed and ready to go.
For versions of Ubuntu between 14.04 LTS (Trusty Tahr) and 15.10 (Wily Werewolf), as well as Ubuntu flavours that don’t include snap by default, snap can be installed from the Ubuntu Software Centre by searching for snapd.
Alternatively, snapd can be installed from the command line:
sudo apt update
sudo apt install snapd
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install juju-lnav, simply use the following command:
sudo snap install juju-lnav
Browse and find snaps from the convenience of your desktop using the snap store snap.
