Help migrating an equipment

[nataklug]

Hello guys,

I am using Cacti and I had an equipment change in my network. I wish I can save the data from the old equipment and use the same database to insert the new equipment data. How can I do so? Is it possible or I will need to create a new graph?

Regards,

So, you simply want to continue the graphs with the new host?
This is possible, but requires a lot of manual changes. Are you sure, that the new equipment will respond to each request, just like the old one did?

Hello gandalf,

Actually I just need the ethernet interfaces to respond and, yes, it will respond just like the old one (I am changing my border router from a Mikrotik host to a Vyatta host, both unix like, and capable of running snmp.

One of my interfaces configured itself all alone and got the old data, so it's running. But the other one (both are WAN interfaces using VLAN in my network scenario) was not able to continue the graph.

Where shall I manually change?

You will create the "new graph" just as usual.
This will create a data source implicitely.
This, in turn, will "define" a new rrd filename. This file is NOT created instantaneously - it will be created on next poller run.

The task now is to replace the new rrd filename by the filename used by the "old" graph. The poller will then fill in all new data into the "old" file. And as the "new" graph will now use the "old" file as well, all is fine.

Thank you gandalf, it worked!
