I'm getting the dreaded "Data is not available" graphs.
Yesterday I added a node to our netflow sources, and everything was working fine. I checked this morning and it was still working! I then added a second node, and went to grab a cup of coffee. After coming back, I see the first node is now showing "Data is not available" while the second node is showing flows correctly.
I've waited a half hour now, so I don't think this is an issue with it not being polled or enough flows being sent to graph. I also verified the configuration between the two nodes is the same, and I do see flows being exported when I issue a show command. I've now tried to remove the first node from our netflow sources and added it back in -- still a no go.
Any ideas on why it would suddenly stop showing data? Maybe something wrong with our database?
