vm-patch-metrics

vm-patch-metrics is a helper tool for VictoriaMetrics. I wrote it for removing "bad" points from metrics without losing the rest of the metrics.

What it does:

1. Exports the matching metrics to a .jsonl file
2. Removes datapoints from each line that fall within the -remove-start and -remove-end times, writing them to a new .jsonl file
3. Deletes the matching metrics from VictoriaMetrics. (For all time!)
4. Imports the metrics without the removed dates back into VictoriaMetrics.

This is a quick project and I won't guarantee you won't lose data in the process. You've been warned!
