Simple example snap to show how to send journal messages from a device to a remote journal server. This uses systemd-journal-upload.
sudo snap install logsync-james --devmode
Note that devmode is needed as the snap needs privileged interfaces. This can be avoided by using a brand store and a snap declaration assertion.
To connect the interfaces:
sudo snap connect logsync:log-observe
sudo snap connect logsync:config-logsync
snap connections logsync-james
Set up log-sync over HTTP:
sudo snap set logsync-james url="http://example.com:19532"
Set up log-sync with custom certificates:
sudo snap set logsync-james url="https://example.com:19532"
sudo snap set logsync-james cert="/path/to/pem-encoded/certificate"
sudo snap set logsync-james key="/path/to/pem-encoded/certificate-key"
sudo snap set logsync-james ca=`LS0tLS1CRUdJTiBSU0EgUFJJVkFUR...`
The certificate settings (cert, key and ca) can be a path to a file or the
base64-encoded file.
