Nagios Support Forum

Team,

Recently we did Nagios XI migration from one Linux server to another Linux server. We observed that Graphs for a week (29th April to 3rd May) are missing after migration. Is there a way to get the missing Graphs from old server and append it in the new server.

Regards,
Pratap

Not very easily without overwriting the new rrds, but if you have yet to collect any new information only on the new server, you should be able to just copy and overwrite the rrds from the old sever to the new one.

I wrote a tool that allows you to do this:

Performance Data Tool

Keep in mind there is a javascript/jquery bug that I am yet to address (the screen does not sometimes refresh).

The tool actually uses a script called rrdmerge which does what you are wanting.
