Constants ¶
const STATIC_ROOT string = "html/static/"
const STATIC_URL string = "http://redskull.iamtherealbill.com/static/"
Variables ¶
var NodeMaster = new(common.NodeStore)
NodeMaster is deprecated. Previously/currently used for storing node connections. It needs refactored to use the constellation-wide node routines
var TemplateBase string
Functions ¶
func APIAddSlave ¶
APIAddSlave is the API call handler for adding a slave
func APIFailover ¶
func APIGetMaster ¶
func APIGetPodMap ¶
func APIGetPods ¶
func APIGetSlaves ¶
func APIMonitorPod ¶
func APIRemovePod ¶
func AddNode ¶
AddNode isn't currently used but would add a non-master, non-slave node. This will be refactored out to a provisioning layer
func AddNodeHTMLProcessor ¶
AddNodeHTMLProcessor is the target for the AddNode form's action
func AddPodForm ¶
AddPodForm displays the form for adding a pod
func AddPodHTML ¶
AddPodHTML is the action target for adding a pod. It does the heavy lifting
func AddPodJSON ¶
func AddSentinelForm ¶
AddSentinelForm displays the form for adding a sentinel
func AddSentinelHTML ¶
AddSentinelHTML does the heavy lifting of adding a sentinel. It is the action target for the sentinel add form
func AddSlaveHTML ¶
AddSlaveHTML shows the slave addition form
func AddSlaveHTMLProcessor ¶
AddSlaveHTMLProcessor is the action target for the AddSlaveHTML form
func BalancePodProcessor ¶
BalancePodProcessor calls the constellation's BalancePod function for the pod
func Clone ¶
Clone is not currently exposed as it comes from the first incarnation of the idea of a Redis manager. It will likely be incorporated into the pod-level handlers and exposed through that route.
func CloneServer ¶
func CloneServer(originHost, cloneHost string, promoteWhenComplete, reconfigureSlaves bool, syncTimeout float64, roleRequired string) (result map[string]string)
TODO?: rename/copy this to have MigratePodToNewPod and CloneServer ? CloneServer does the heavy lifting to clone one Redis instance to another.
func CommifyFloat ¶
CommifyFloat turns a float into a string with comma separation
func ConstellationInfoHTML ¶
func ConstellationInfoJSON ¶
func DoFailoverHTML ¶
DoFailoverHTML is how the UI initiates a failover for a pod
func DoFailoverJSON ¶
func GetNodeJSON ¶
GetNodeJSON returns the JSON output of the data known about a node
func HumanizeBigBytes ¶
HumanizeBigBytes transforms a uint64 to a human readable string such as "100Kb"
func HumanizeBytes ¶
HumanizeBytes transforms an int to a human readable string such as "100Kb"
func HumanizeCallStats ¶
HumanizeCallStats is used to convert Redis' calls stats to something humans can easily read. This means converting microseconds to milliseconds where appropriate, adding commas, and hopefully soon upconverting to seconds, minutes, hours, days, etc. where approriate
func HumanizeSlowlog ¶
HumanizeSlowlog is used to convert Redis' calls stats to something humans can easily read. This means converting microseconds to milliseconds where appropriate, adding commas, and hopefully soon upconverting to seconds, minutes, hours, days, etc. where approriate
func IntFromFloat64 ¶
IntFromFloat64 provides a convenience function fo convert an int to a float insert screed about how you probably should not do it but sometimes you need to here.
func RebalanceHTML ¶
WEB UI CALL
func RebalanceJSON ¶
func RemovePodHTML ¶
RemovePodHTML is the action target for adding a pod. It does the heavy lifting
func ResetPodProcessor ¶
ResetPodProcessor is called to reset the pod's slave&sentinel configuration
func Root ¶
Root shows the index page of Red Skull, if you didn't want to display the dashboard at the root.
func SetConstellation ¶
func SetConstellation(con actions.Constellation)
Types ¶
type ErrorMetrics ¶
type ErrorMetrics struct {
NoQuorum int
MissingSentinels int
TooManySentinels int
NoValidSlave int
InvalidAuth int
TotalErrorPods int
ConnectionError int
NoFailover int
Groups map[string][]interface{}
}
ErrorMetrics is a struct used by the UI to display the current breakdown of errors among the pod.
type InfoResponse ¶
InfoResponse represents the information returned in an API call
type PageContext ¶
type PageContext struct {
Title string
SubTitle string
Data interface{}
Static string
ViewTemplate string
CurrentURL string
Constellation *actions.Constellation
NodeMaster common.NodeManager
Pod *common.RedisPod
Node *common.RedisNode
Refresh bool
RefreshTime int
RefreshURL string
Error error
}
PageContext holds all the contextual information a page will want to return, use, or display
func NewPageContext ¶
func NewPageContext() (pc PageContext, err error)
NewPageContext instantiates and returns a PageContext with "global" data already set.
