Amazon CloudWatch metrics
Amazon Managed Service for Prometheus vends usage metrics to CloudWatch. These metrics provide visibility about your
workspace utilization. The vended metrics can be found in the AWS/Usage and
AWS/Prometheus namespaces in CloudWatch. These metrics are available in CloudWatch
for
no charge. For more information about usage metrics, see CloudWatch usage metrics.

*Some of the reasons that cause samples to be discarded are as follows.
|
Reason |
Meaning |
|---|---|
|
greater_than_max_sample_age |
Discarding log lines, which are older than the current time |
|
new-value-for-timestamp |
Duplicate samples are sent with a different timestamp than was previously recorded |
|
per_metric_series_limit |
User has hit the active series per metric limit |
|
per_user_series_limit |
User has hit the total number of active series limit |
|
rate_limited |
Ingestion rate limited |
|
sample-out-of-order |
Samples are sent out of order and cannot be processed |
|
label_value_too_long |
Label value is longer than allowed character limit |
|
max_label_names_per_series |
User has hit the label names per metric |
|
missing_metric_name |
Metric name is not provided |
|
metric_name_invalid |
Invalid metric name provided |
|
label_invalid |
Invalid label provided |
|
duplicate_label_names |
Duplicate label names provided |
A metric not existing or missing is the same as the value of that metric being 0.

RuleEvaluations,
and RuleEvaluationFailureshave the RuleGroup dimension of
