# 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!

## Usage:

    Usage of vm-replace-metrics:

        -export-end string

            End time for the exported metrics (default: current time)

        -export-start string

            Start time for the exported metrics

        -file string

            File path to export metrics to (default "./metrics.jsonl")

        -match string

            Metric expression to export from VM

        -password string

            VM user password to authenticate

        -remove-end string

            End time of the points to remove from exported metrics (default: current time)

        -remove-start string

            Start time of the points to remove from exported metrics

        -url string

            VM url (default "http://localhost:8428")

        -user string

            VM user to authenticate

        -insecure bool

            Ignore server certificate issues

Example of removing December 1-4, 2022 data from data exported since Jan 1, 2020:

```./vm-replace-metrics -url http://localhost:8428

-user user -password password

-match 'my_cool_metric{mylabel="a", otherlabel=~"b_.*"}'

-export-start 2020-01-01T00:00:00+05:00

-remove-start 2022-12-01T00:00:00Z05:00

-remove-end 2022-12-05T00:00:00Z05:00

```
