Nagios Network Analyzer CPU 100% Gateway Timeout when extracting Reports

[smallboy679]

hi Nagios Community

we are currently testing out Nagios Network Analyzer on our Gateways..

The Network Analyzer Application does not give pdf reports and Apache is showing under htop 100% utilization..

my Core Count is 18 and memory 32g..

my Nic is 10Gbps..

can please direct me to documentation that will optimize the reporting as well as Application..

as we are trialing out this application..

Thanks

Hey @smallboy679

Glad to hear your giving network analyzer a shot. I wasn't able to find any documentation or tips for optimizing your NNA server. For the PDF reports is there certain reports or pages you are looking for PDF extracts of? I see an export as PDF option on most pages that have information but im unsure if we are missing it in a few locations. Here is some documentation on our reports and if you have any suggestions on things that NNA is lacking feel free to let us know!

Thank you for the link,

just one question

it just came to me, are the interface for the netflow ingress and the Nagios Network Analyzer the same..

currently both are using the 10gbps NIC, maybe that is why the Gateway is timing out..

is it best pratice to keep the Nagios Network Analyzer interface separate from the Ingress Netflow interfaces...

Appreciate your advise

Thanks

Hey @smallboy679

I will preface my knowledge in this area is limited. From what i've researched it seems that if your having issues with 100% utilization that it may be best to have them be separate to avoid possible resource contention between nna commands and the netflow data coming in. That being said I didnt find any posts about doing so with NNA, there has been some things with XI though, and I don't know what the process would look like. If I find anymore data on it I'll make sure to let you know.
