nsp VS arkime

Arkime: https://arkime.com/ Packet capture and search

Also consider running full PCAP collection with https://arkime.com/ so you can monitor your past network traffic. That has come in handy many times for security and troubleshooting, and doesn't require as much horsepower as you might think.

Anyone using Arkime? https://arkime.com/

dns && ip.src==x.y.z.w Note that this display filter will not display the DNS replies for the requests sent by x.y.z.w if you want those as well then it will be dns && ip.addr==x.y.z.w Although DNS will be displayed in upper case in Wireshark, it has to be in lower case in the display filter, that said, like others said based on your exact needs and the size of your resulting pcap / pcapng file you may want to look at capture filters, finally if you are dealing with multiple gegabytes file(s) you may want to take a look at another tool like Arkime (formerly moloch) https://arkime.com/

Full PCAP's? Look at https://arkime.com/ or network miner. Arkime is probably more what you're looking for. But I love network miner

I used moloch which is now https://arkime.com/. It used to be free and was a great tool for pcaps. Uses elastic underneath.

Arkime is secure, scaleable, indexed packet capture and search tool that can improve your network security by providing greater visibility. This open-source tool stores and indexes network traffic in standard PCAP format. Our thanks for the suggestion goes to Security_Chief_Odo.

I would suggest instead of graylog look into something like this https://arkime.com/
