Parse System Metrics and Warn on Threshold Breaches

Problem: Parse System Metrics and Emit Threshold Warnings Implement a script that reads multiple lines from standard input. Each line is split by whitespace into columns. Given: A column number n, 1-indexed; A numeric threshold; A required count x. Scan every input line: If the line does not have column n, skip it; If column n is not numeric, skip it, e.g. header lines; If the numeric value in column n is greater than threshold, increment a counter; Once the counter reaches x, print a warning and terminate. Command-line Arguments The real script should support: python monitor.py --column n --threshold threshold --count x < input.txt Where: --column: positive integer, the 1-based column index; --threshold: numeric threshold; --count: positive integer, the number of breaches needed to trigger a warning. For online testing, the script may also support putting the configuration in the first input line: n threshold x The remaining lines are metric logs. Output Format If a warning is triggered, print: WARNING: column {n} exceeded {threshold} at least {x} times If no warning is triggered, print nothing. Example Input: 3 100 2 procs -----------memory---------- ---swap-- -----io---- -system-- -------cpu------- r b swpd free buff cache si so bi bo in cs us sy id wa st gu 2 0 101 5630832 1 0 99 5630832 2 0 200 5630832 Output: WARNING: column 3 exceeded 100 at least 2 times Constraints Up to 10^6 input lines; Each line length up to 10^4; Process the input as a stream; do not load the whole log into memory.
