All of the output indicates that there is either a problem with your broccoli-python
bindings, a firewall issue (not likely in your case since they all seem to be running on a
single host), or there could be other Bro processes that have accidentally been forgotten
about. To help debug this, could you send me…
- The content of node.cfg
- The output from the "ps.bro" command in broctl
- A snippet from your manager's communication.log when you try to run
You might also want to try removing the old installation and reinstalling (save your site/
directory!). I'm starting to suspect that something may have happened recently that
is causing this to be a problem with the broccoli-python bindings if you reinstall in
Also, I am wondering what kind of issues I might run
several geographically disparate clusters from a single manager.
Currently, I have each setup as a separate bro cluster. I am most
concerned about the amount of traffic and possible congestion this
This is a very similar deployment model to the deep cluster we've been talking about
for a little while but this is more of a shallow cluster model. :) I don't have any
experience yet with people using remote managers, I suppose a lot of potential performance
problems could come from the workers -> manager connection not being fast enough.
I'd be glad to work on it directly with you, it would be great to finally get some
relevant experience with that deployment model.
Is there a way to measure the amount of traffic
the workers and manager if all are on the same server?
You can always run tcpdump on your loopback interface. Capstats should even work on the
loopback interface. Unfortunately, you'd only be able to filter down easily to
traffic that is being sent to your manager. Traffic sourced from your manager process
would be a bit harder, but there isn't much of that fortunately.
