Is it safe to delete shards in _internal database?

1

will deleting the following shards impact influxdb service ?

name: _internal
id database retention_policy shard_group start_time end_time expiry_time owners
"-- -------- ---------------- ----------- ---------- -------- ----------- ------
2 _internal monitor 2 2019-12-11T00:00:00Z 2019-12-12T00:00:00Z 2019-12-19T00:00:00Z
3 _internal monitor 3 2019-12-12T00:00:00Z 2019-12-13T00:00:00Z 2019-12-20T00:00:00Z
7 _internal monitor 7 2019-12-13T00:00:00Z 2019-12-14T00:00:00Z 2019-12-21T00:00:00Z

@aditya It should be fine. The _internal database just captures internal InfluxDB performance metrics. Nothing depends on these metrics other than maybe a dashboard that visualizes the data. In fact, you can disable the _internal data collection and storage altogether if you want. Just update the following in your InfluxDB config file:

[monitor]
  store-enabled = false
