Expressions support

The expressions support is based on ideas from go-away but with different opinions about how things should be done.

Functions ¶

func BotEnvironment ¶

func BotEnvironment(dnsObj *dns.Dns) (*cel.Env, error)

BotEnvironment creates a new CEL environment, this is the set of variables and functions that are passed into the CEL scope so that Anubis can fail loudly and early when something is invalid instead of blowing up at runtime.

func Compile ¶

func Compile(env *cel.Env, src string) (cel.Program, error)

Compile takes CEL environment and syntax tree then emits an optimized Program for execution.

func Load1 ¶

func Load1() float64

func Load5 ¶

func Load5() float64

func Load15 ¶

func Load15() float64

func New ¶

func New(opts ...cel.EnvOption) (*cel.Env, error)

func ThresholdEnvironment ¶

func ThresholdEnvironment() (*cel.Env, error)

NewThreshold creates a new CEL environment for threshold checking.
