Yes, I agree, this is a super common "discussion" between app and network teams... I'm a converted network engineer (like I bet many people are these days)... so know all the tricks to push it back on the app :) On Tue, Nov 6, 2018 at 12:25 PM Wes Sisk (wsisk) wrote: > Nick, > > The command is i

Not a bad idea, but they have so much many more tools to do this. I'll keep this in mind though. Thanks. On Tue, Nov 6, 2018 at 11:06 AM Matt Jacobson wrote: > You could use the CLI packet capture with some filters to maximize the > capture window, run the dbreplication command once or twice, an

Nick, The command is invoking database commands that Cisco does not own. They are not being obtuse; they genuinely do not know. It will cause a spike in database communication between nodes. My first guess is very much in line with yours that the burst in traffic exceeds certain QoS queues. I

You could use the CLI packet capture with some filters to maximize the capture window, run the dbreplication command once or twice, and then stop the capture. Pop open RTMT, download the capture(s), and then see what you find in Wireshark. On Tue, Nov 6, 2018 at 20:58 Nick Barnett wrote: > We al

We all know the max latency is 80ms, but ours occasionally goes over. I'm trying to track down why but the network team cannot find an issue. We are able to reproduce the issue repeatedly by running "utils dbreplication runtimestate." Whether this is causing the issue (I doubt it) or that command j
