TOP 5 Talkers Blank

[matt.lilek]

Hello Team,

The TOP 5 Talkers is not showing on our one instance of NNA. I have rebooted it and upgraded it to the latest version (was on 2.3.1) and was wondering what my next step should be. Let me know.

Thank you,

Matt

Hello, @matt.lilek. Is the graph next to the top 5 talkers table empty as well or not?
Most often this issue is caused by incorrect timestamps in packets that your network devices are sending. Please make sure that the time is in sync between the Nagios Server and network devices.

What kind of network devices are sending the data to the NNA server?
Has the TOP 5 talkers table worked in the past?

Please upload a few nfcapd files from the following folder:

Code: Select all

/usr/local/nagiosna/var/name_of_the_source/flows/

Also, please run the TCP dump:

Code: Select all

 tcpdump -i any -s 0  port xxx -w /tmp/nagios.pcap

*Replace xxx after port with the port number that your NNA listens on

And upload the /tmp/nagios.pcap file.

how do i upload those files here?

[matt.lilek]

so there is the one file, but how do i do a whole folder with all the flows, not gonna up each one individually.

@matt.lilek, Do you have a google drive or some other cloud storage where you can upload everything and share a public link with us?

FLOWS and Nagios

@matt.lilek, Unfortunately, the TCP dump didn't get captured correctly. But your flow files appear to be ok. What kind of device is sending the flow data to your NNA? Is the device located in the same or different timezone?
Also, please take a screenshot of the whole web page with top 5 talkers table.

[matt.lilek]

These are all Cisco Routers located all over the Americas, so same timezone and different timezones. Just for the record this was working all fine a couple months ago. I have not come across 1 in the 100+ we have that is showing any talk talker data. Let me know if you need anything else on my end. Thank you!

Hey Matt

Can you share the following from the server after trying to load talker data

Code: Select all

tail -100 /var/log/httpd/error_log
