I just installed FlowDoh on my Docker container. It's using debian:jessie, nfsen 1.3.8, nfdump 1.6.13, and flowdoh 1.0.2. You can see my system's configuration at: https://github.com/richb-hanover/nfsen-dockerized/blob/adding-flohdoh/Dockerfile
I have two observations: 1) It is slow. Opening the Plugins tab takes almost 30 seconds to summarize data arriving from a single exporter averaging 15-20 flows/second. Switching to the Graphs tab, then back to Plugins causes another 30-second hang. I checked top, and no process ever use > 1% of the processor. Any thoughts on this? Is this expected? 2) I get many errors in the apache2/error.log (see log messages below) These sometimes occur when I click the Alerts tab of the flowdoh window, which also displays, "Error occurred communicating with the backend." I know that I do not have any FlowDoh alerts defined (the backend alerts directory is empty). I see that Jens Hektor reported this in https://sourceforge.net/p/nfsen/mailman/message/31160829/ Has anyone fixed/worked around these messages?
