Suricata 7 , dpdk , Redhat 8 initial setup advice and tips appreciated

atbohmer · April 6, 2023, 11:08am

Hi,
Finnaly managd to get it working all together, but please need to reflect if I made the right choices and configuration assumptions. For now running with root priviliges but hope to run suricata with dpdk under a non root account.

By listing 4 interfaces each with threads: auto with 128 cores, I think it is going to create 512 threads (4x128). That is probably excessive even for this machine. What happens if you limit it to 16 or 32 per interface?

atbohmer · April 7, 2023, 7:22am

Indeed, it took a hour to start, but it started Is there some rule of thumbd regarding theads, interfaces and cores of just try and find out?

32 Instead of auto for threads fired up suricate within minutes:

Regarding CPU affinity and NUMA, how do I pin those dpdk interfaces? I know how to find out which interface relates to which node, but how to make configure this right in suricata?

lukashino · April 20, 2023, 7:08pm

I think you could order your interface in within the interfaces list so that you first start with the first NUMA node and then define the NICs located on the other NUMA node.

something like

dpdk:
  interfaces:
    - interface: 7b:00.0 (node 0)
      threads: 4
    - interface: 7b:00.1 (node 0)
      threads: 4
    - interface: 8c:00.0 (node 1)
      threads: 4
    - interface: 8c:00.0 (node 1)
      threads: 4

threading:
  set-cpu-affinity: yes
  workers: [0-7 (NUMA 0), 64-71 (NUMA 1)]

Hopefully my “illustration” is correct and helpful.

atbohmer · April 21, 2023, 9:08am

Thanks, but my NUMA config is more complicated then 1-10 for 0 and 11-20 for 1, it is mixed sigh:
NUMA node0 CPU(s): 0-31,64-95
NUMA node1 CPU(s): 32-63,96-127

So this works for me the way suricata handles affinity with threads: 24 per interface:
cpu: [ “6-29”,“38-61”,“64-87”,“96-119” ]
And this interface order:
- interface: 0000:10:00.0
- interface: 0000:84:00.0
- interface: 0000:10:00.1
- interface: 0000:84:00.1

Perfect, great to hear that.
