FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.
Description This article describes how to identify the daemon/process using which CPU core.
Solution 1) Identify the Process ID(PID) of a daemon/process before it is possible to trace it. Below is the command to get the PID of a daemon:
#diag sys top [JRun Time: 1 days, 23 hours and 54 minutes 0U, 0N, 0S, 100I, 0WA, 0HI, 0SI, 0ST; 7996T, 5392F ipshelper 330 S < 0.0 1.6 ipsengine 333 S < 0.0 1.2 ipsengine 331 S < 0.0 1.2 ipsengine 332 S < 0.0 1.2 reportd 200 S 0.0 1.1 cmdbsvr 159 S 0.0 0.4 pyfcgid 186 S 0.0 0.4 scanunitd 203 S < 0.0 0.3 scanunitd 239 S < 0.0 0.3 scanunitd 238 S < 0.0 0.3 scanunitd 236 S < 0.0 0.3 scanunitd 237 S < 0.0 0.3 httpsd 185 S 0.0 0.3 pyfcgid 233 S 0.0 0.3 pyfcgid 234 S 0.0 0.3 pyfcgid 235 S 0.0 0.3 httpsd 243 S 0.0 0.3 httpsd 284 S 0.0 0.3 cw_acd 218 S 0.0 0.3 forticron 192 S 0.0 0.2
-> Process ID (PID)
2) After tracing the PID of a daemon, issue the following commands:
# diag sys process dump 7091 | grep Cpus_allowed Cpus_allowed: f < ------- Hex Value Cpus_allowed_list: 0-3 < ------- list of CPU core
Convert the HEX value to binary to find out the core using the following table: Decimal Binary CPU used 1 0001 cpu-0 2 0010 cpu-1 3 0011 cpu-0 and cpu-1 4 0100 cpu-2 ....... 15 1111 cpu-0, cpu-1, cpu-2 and cpu-3 16 10110 cpu-1, cpu-2, and cpu-4 .......
