This is a real life sample alert from indeni.
Having one or more NICs assigned to the same CPU core as an fw_worker will result in degraded performance.
Core 0 is assigned to both eth1 and fw_0
Manual Remediation Steps:
Update the affinity of cores. Follow the CoreXL documentation.
How does this alert work?
indeni runs “fw ctl affinity -l” and analyzes the output, looking for a situation where one of the fw lines (fw_0, fw_1, etc.) are associated with a core that is also associated with a NIC.
