Bug #7137
Updated by UPPER KEES 5 months ago
More info: https://forum.suricata.io/t/cpu-affinity-with/4615
In a nutshell, I have this NUMA layout:
<pre><code class="shell">
root# lscpu | grep NUMA
NUMA node(s): 2
NUMA node0 CPU(s): 0,2,4,6,8,10,12,14,16,18
NUMA node1 CPU(s): 1,3,5,7,9,11,13,15,17,19
</code></pre>
The documentation (https://docs.suricata.io/en/latest/performance/high-performance-config.html) shows the following:
<pre><code class="shell">
threading:
cpu-affinity:
- management-cpu-set:
cpu: [ "1-10" ] # include only these CPUs in affinity settings
- receive-cpu-set:
cpu: [ "0-10" ] # include only these CPUs in affinity settings
- worker-cpu-set:
cpu: [ "18-35", "54-71" ]
mode: "exclusive"
prio:
low: [ 0 ]
medium: [ "1" ]
high: [ "18-35","54-71" ]
default: "high"
</code></pre>
When I apply this line @high: [ "0,2,4,6,8,10,12,14,16", "1,3,5,7,9,11,13,15,17" ]@, ]@ or any other with strings, Suricata fails to start with the error:
<pre><code class="shell">
Error: affinity: worker-cpu-set: invalid cpu range (not an integer): "0,2,4,6,8,10,12,14,16"
</code></pre>
How can I define these NUMA nodes? The documentation shows a way, but the software does not accept it in the configuration. Only consequtive CPU ranges work, e.g. @"0-5", "10-15"@, but that's not how my NUMA looks like.
I'm using Debian 12 with Suricata 7.0.6-1~bpo12+1.
