Functions ¶
func QueryAndValidateMetrics ¶
func QueryAndValidateMetrics(query string, validate func(datadogV1.MetricsQueryMetadata) error) error
QueryAndValidateMetrics queries metrics from Datadog.
query can be a query string like the following examples: - "avg:kubernetes.cpu.user.total{*}" - "system.cpu.idle{*}"
Note that this function does not validate the query on its own. For example, the following query is invalid:
"avg:kubernetes.cpu.user.total"
You get:
Error parsing query: \nunable to parse avg:kubernetes.cpu.user.total: Rule 'scope_expr' didn't match at ” (line 1, column 30).
because it lacks the scope_expr, which is required for the query to be valid. This specific query should be:
"avg:kubernetes.cpu.user.total{*}"
The validate function is called for each series in the response. You can use this function to validate the metadata of the series. The whole QueryAndValidateMetrics function returns an error if any of the validate calls return an error.
func RequireMetrics ¶
func RequireMetrics(t *testing.T, query string, validate func(datadogV1.MetricsQueryMetadata) error)
RequireMetrics queries metrics from Datadog and validates them.
query can be a query string like the following examples: - "avg:kubernetes.cpu.user.total{*}" - "system.cpu.idle{*}"
Note that this function does not validate the query on its own. For example, the following query is invalid:
"avg:kubernetes.cpu.user.total"
You get:
Error parsing query: \nunable to parse avg:kubernetes.cpu.user.total: Rule 'scope_expr' didn't match at ” (line 1, column 30).
because it lacks the scope_expr, which is required for the query to be valid. This specific query should be:
"avg:kubernetes.cpu.user.total{*}"
The test fails if the query returns no series, or if any of the validate calls return an error.
