See https://prometheus.io/docs/prometheus/latest/querying/functions/#irate

func Irate(v cog.Builder[Expr]) *FuncCallExprBuilder

LabelReplace🔗

matches the regular expression regex against the value of the label src_label.

See https://prometheus.io/docs/prometheus/latest/querying/functions/#rate

func Rate(v cog.Builder[Expr]) *FuncCallExprBuilder

Resets🔗

For each input time series, resets(v range-vector) returns the number of counter resets within the provided time range as an instant vector. Any decrease in the value between two consecutive float samples is interpreted as a counter reset. A reset in a native histogram is detected in a more complex way: Any decrease in any bucket, including the zero bucket, or in the count of observation constitutes a counter reset, but also the disappearance of any previously populated bucket, an increase in bucket resolution, or a decrease of the zero-bucket width.

resets should only be used with counters and counter-like native histograms.

If the range vector contains a mix of float and histogram samples for the same series, counter resets are detected separately and their numbers added up. The change from a float to a histogram sample is not considered a counter reset. Each float sample is compared to the next float sample, and each histogram is compared to the next histogram.

See https://prometheus.io/docs/prometheus/latest/querying/functions/#resets

func Resets(v cog.Builder[Expr]) *FuncCallExprBuilder

Scalar🔗

func Scalar(v cog.Builder[Expr]) *FuncCallExprBuilder

Sgn🔗

func Sgn(v cog.Builder[Expr]) *FuncCallExprBuilder

Sort🔗
