Cloud VPS Server Admin Log
All projects can record Server Admin Log messages by sending a message in the format !log <project> <message> on the #wikimedia-cloud connect irc channel. Messages will be added to a Wikitech page like Nova Resource:<project>/SAL and are also available on the SAL tool.
Toolforge tools can do the same thing by using tools.<toolname> as the project;
dologmsg command in a Toolforge bastion shell can be used to send such messages (the project name is automatically included).
