Functions

func KeyToField

func KeyToField(key string) string

KeyToField format key to struct field name, e.g. instance_id -> InstanceId TODO key demo: datanodePort or HA_state or instance_state, key is not unified, this is bad design

func OutputToMap

func OutputToMap(cmdOutput []string, countList []int, otype string) (map[string]string, error)

OutputToMap filter valid output, transfer it to key/value, check if result count is in count list

func ParseChannel

func ParseChannel(topology string, ctype string, portMap map[string]string) (*dtstruct.BaseInfo, error)

ParseChannel parse channel info from gs_ctl query

func ResetValue

func ResetValue(structInstance interface{}, infoMap map[string]string, ignoreMiss bool) error

ResetValue reset field of struct instance value using key/value in info map

func UpdateHostAndPort

func UpdateHostAndPort(kvs map[string]string, ip string, hostname string, port string)

UpdateHostAndPort replace ip in key hostname use real host name
