Linux, CPU metrics, count, (online/offline), ...

Hello,
Would it be possible to extend/add System.CPU.Count() metric provided by subagents/linux with parametrized one that would enable count of online/offline CPUs in the system.
Example system with 24 cores with 2 cores online:
...:# lscpu --online --extended CPU NODE SOCKET CORE L1d:L1i:L2:L3 ONLINE MAXMHZ MINMHZ MHZ 12 0 0 0 0:0:0:0 yes 3200.0000 1200.0000 1197.3630 13 0 0 1 1:1:1:0 yes 3200.0000 1200.0000 1197.3240 ...:# lscpu --offline --extended CPU NODE SOCKET CORE L1d:L1i:L2:L3 ONLINE MAXMHZ MINMHZ MHZ 0 0 0 0 0:0:0:0 no 3200.0000 1200.0000 1197.3800 1 0 0 1 1:1:1:0 no 3200.0000 1200.0000 1197.4100 2 0 0 2 2:2:2:0 no 3200.0000 1200.0000 1197.3630 3 0 0 3 3:3:3:0 no 3200.0000 1200.0000 1200.0000 4 0 0 4 4:4:4:0 no 3200.0000 1200.0000 1197.8280 5 0 0 5 5:5:5:0 no 3200.0000 1200.0000 1197.4139 6 1 1 6 8:8:8:1 no 3200.0000 1200.0000 1197.3640 7 1 1 7 9:9:9:1 no 3200.0000 1200.0000 1197.5330 8 1 1 8 10:10:10:1 no 3200.0000 1200.0000 1197.4250 9 1 1 9 11:11:11:1 no 3200.0000 1200.0000 1198.4170 10 1 1 10 12:12:12:1 no 3200.0000 1200.0000 1197.3580 11 1 1 11 13:13:13:1 no 3200.0000 1200.0000 1197.4180 14 0 0 2 2:2:2:0 no 3200.0000 1200.0000 1197.5649 15 0 0 3 3:3:3:0 no 3200.0000 1200.0000 1197.3621 16 0 0 4 4:4:4:0 no 3200.0000 1200.0000 1200.0000 17 0 0 5 5:5:5:0 no 3200.0000 1200.0000 1197.4301 18 1 1 6 8:8:8:1 no 3200.0000 1200.0000 1200.0000 19 1 1 7 9:9:9:1 no 3200.0000 1200.0000 1197.5850 20 1 1 8 10:10:10:1 no 3200.0000 1200.0000 1197.5100 21 1 1 9 11:11:11:1 no 3200.0000 1200.0000 1197.5310 22 1 1 10 12:12:12:1 no 3200.0000 1200.0000 1197.5060 23 1 1 11 13:13:13:1 no 3200.0000 1200.0000 1197.3719Metric is provided via sysfs:
# cat /sys/devices/system/cpu/present
0-23# cat /sys/devices/system/cpu/online
12-13Etc:
- on this exact system System.CPU.Count will return: 14 for number of CPU's.
thank you,
