Functions ¶
func Export_All_Keys ¶ added in v1.1.3
keys is function for command `keys` output all keys in rdb file(s) get from args
func InitHTMLTmpl ¶
func InitHTMLTmpl()
func ParseUnitToBytes ¶ added in v1.1.3
将带单位的字符串转换为字节数
func ServeHTML ¶
func ServeHTML(w http.ResponseWriter, layout string, content string, data map[string]interface{})
ServeHTML generate and write html to client
func ToCliWriter ¶
ToCliWriter dump rdb file statistical information to STDOUT.
func ToCliWriterToFile ¶ added in v1.0.6
ToCliWriter dump rdb file statistical information to file.
Types ¶
type Counter ¶
type Counter struct {
// contains filtered or unexported fields
}
Counter for redis memory usage
func NewCounter ¶
func NewCounter(config *CounterConfig) *Counter
NewCounter return a pointer of Counter
func (*Counter) Count ¶
Count by various dimensions，show.go NewCounter 后，调用此方法，遍历decoder的entry, <-chan表示一个只能接收数据的单向通道
func (*Counter) GetLargestEntries ¶
GetLargestEntries from heap, num max is 500. 过滤掉小于阈值的key
func (*Counter) GetLargestKeyPrefixes ¶
func (c *Counter) GetLargestKeyPrefixes() []*PrefixEntry
GetLargestKeyPrefixes from heap
func (*Counter) GetLenLevelCount ¶
func (c *Counter) GetLenLevelCount() []*PrefixEntry
GetLenLevelCount from map
type CounterConfig ¶ added in v1.1.4
type CounterConfig struct {
// Bigkey数量阈值，默认 500
TopBigKeyNum int
// key前缀分隔符，默认 ":;,_- "
Separators string
// 是否存储所有前缀，仅当你的主机内存足够时开启，默认关闭
// false时，对前缀的存储量进行动态收缩, 前缀个数越多，创建的对象也就越多，从而耗内存就越多,就会因内存不足执行不完, 详见 https://github.com/919927181/rdr/issues/1
StoreAllPrefixes bool
// 前缀数量阈值，默认 500
TopPrefixNum int
// 前缀容器的最大容量，默认值为前缀数量阈值的10倍，可以理解为最大水位线，到达最大水位线，就要去排出一部分水
PrefixContainerMaxCapacity int
// 前缀容器的预缩容数量，可以理解为正常水位线
PrefixPreShrinkNum int
}
v1.1.4 add
type PrefixEntry ¶
type PrefixEntry struct {
Bytes uint64
Num uint64
Db string //之前为int
// contains filtered or unexported fields
}
PrefixEntry record value by prefix
type SafeMap ¶
type SafeMap struct {
// contains filtered or unexported fields
}
SafeMap is a map which concurrency safe
func (*SafeMap) Get ¶
func (m *SafeMap) Get(k interface{}) interface{}
Get from maps return the k's value
func (*SafeMap) Items ¶
func (m *SafeMap) Items() map[interface{}]interface{}
Items returns all items in safemap.
