How to tell when writes are being dropped?

InfluxDB 2

Is there a way to identify when writes are being dropped? For example, if you write to influxDB faster than it can keep up, and set a low CacheMaxMemorySize is there a way to tell if and when writes are being rejected?

I am not sure if this is what you are looking but you can try to monitor influxdb internals with telegraf. Beside that, you can monitor each telegraf agent internally.

As long as InfluxDB returns a HTTP 204, it’s fine.

There are a few 4xx errors for quotas and payload problems.
