Drop metrics that have cardinality above some number:

```

cat sample_metrics.txt | python prometheus_drop_high_cardinality.py 5

```

Input:

```

# HELP metric_name_1 Metric 1

# TYPE metric_name_1 gauge

metric_name_1{label_a="1"} 1

metric_name_1{label_a="2"} 1

metric_name_1{label_a="3"} 1

metric_name_1{label_a="4"} 1

metric_name_1{label_a="5"} 1

metric_name_1{label_a="6"} 1

metric_name_1{label_a="7"} 1

metric_name_1{label_a="8"} 1

# HELP metric_name_2 Metric 2

# TYPE metric_name_2 gauge

metric_name_2{label_b="1"} 1

metric_name_2{label_b="2"} 1

metric_name_2{label_b="3"} 1

# HELP metric_name_3 Metric 3

# TYPE metric_name_3 gauge

metric_name_3{label_a="1",label_c="1"} 1

metric_name_3{label_b="1",label_c="1"} 1

```

Output:

```

# HELP metric_name_1 Metric 1

# TYPE metric_name_1 gauge

# HELP metric_name_2 Metric 2

# TYPE metric_name_2 gauge

metric_name_2{label_b="1"} 1
