Keep showing old node in munin to review data

cn flag

I am using munin to monitor some servers and now I have delete a server but I want to keep the graphs in my overview to be able to compare the data from the old server to the things that happen on the new server (for example questions like "how many apache accesses did we get in May last year on the main webserver (now delete) and how many do we get now on the current webserver?").

I tried to put

[old.example.com]
update no

into my config but the host old.example.com is not visible in the overview.

I also tried to trick munin into "updating" the host like this

[old.example.com]
address cmd:///usr/bin/true

but that also hides the node from my overview.

Is there any way to keep a node visible where I can not update the graphs any longer because I do not own the server/IP any longer?


PS: I saw this similar question but they advice to change the plugins on the node and I can not do that because the node does not exist any longer.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
