Understand Grafana Cloud usage limits

Grafana Cloud continuously provides your account limits in the following metrics:

grafanacloud_instance_metrics_limits
grafanacloud_logs_instance_limits
grafanacloud_traces_instance_limits

To find these limits in your Grafana Cloud instance:

Click Explore (compass icon).
Select grafanacloud-usage from the drop-down menu.
In the Metrics browser query field, enter the metric, for example grafanacloud_instance_metrics_limits.
Click Run query.

The label limit_name provides the specific limit. See below for a complete reference.

`max_query_lookback`	Querier limit on how far back data can be queried.	0 (disabled)

Discarded Spans panel in the Billing dashboard

In the Billing dashboard, there is a panel that shows Discarded Spans and a color-coded legend with a reason why the spans were discarded. The table that follows defines each of those reasons.

Reason for discarded span	Description
`internal error`	A general error that should be further explained in the logs.
`live_traces_exceeded`	Exceeded the max number of traces allowed in the ingester per tenant.
`rate limited`	Exceeded the `ingestion_rate_limit_bytes` limit.
`trace_too_large`	Exceeded the `max_bytes_per_trace` limit.

You can use grafanacloud_traces_instance_percentage_complete_traces_flushed metric. This metric has a value between 0 and 1, indicating the percentage of traces without any orphaned spans when the trace is flushed to storage.

In addition, you can use the grafanacloud_traces_instance_discarded_spans_total:rate5m metric to review the number of discarded spans, including the reasons for discarding, in 5 minute periods.

Grafana Cloud usage

Grafana Cloud continuously provides your account usage in the following metrics:

grafanacloud_instance_metrics_*
grafanacloud_logs_instance_*
grafanacloud_traces_instance_*

For example, to monitor log stream count, you can use grafanacloud_logs_instance_active_streams.

Cloud Traces usage

If you need to have a limit raised, then contact Grafana Support for assistance.
