Functions

func Download

func Download(L *lua.LState) int

Download lua clw:download(filename, filter={}, timeout) error filter table:

{
  log_group_name="/aws/rds/instance/name/rds",
  filter_patern="",
  start_time=timestamp,
  end_time=timestamp,
}

func GetMetricData

func GetMetricData(L *lua.LState) int

GetMetricData lua clw:get_metric_data({start_time=1, end_time=1, queries={}}) result, error

func Loader

func Loader(L *lua.LState) int

Loader is the module loader function.

func New

func New(L *lua.LState) int

New lua new(profile, region) returns (clw_ud, err)

func Preload

func Preload(L *lua.LState)

Preload adds cloudwatch to the given Lua state's package.preload table. After it has been preloaded, it can be loaded using require:

local cloudwatch = require("cloudwatch")
