Analyzer sysctl

# Name

sysctl - Run sysctl -a to get all sysctl parameters

The analyzer executes the sysctl -a command to collect all system kernel parameters. In software performance analysis, these parameters are critical for verifying whether the system kernel configuration matches the software’s runtime requirements, as improper kernel settings can directly lead to performance bottlenecks.
