It's common for a LogScale action to send an email or some other message
to specified users, administrators. Within those actions may be hyperlinks
for the receiver, the user to click to go to the appropriate page within
the LogScale User Interface or elsewhere. To simplify entering of content
for messages or other actions, the ACTION_LINK_BASE_URL
environment variable may be used to set the base URL to use in links sent
This property is only important if you plan to use actions that send
messages that include links to the LogScale User Interface.
Below is an example of how to set this variable in the configuration file:
Incidentally, any trailing slashes in the URL will be discarded. Also,
it's not a problem if the URL given is only reachable behind a VPN. This
is because the user's browser will still be able to access it —
assuming they are connected through the VPN.
