RedisSentinel

interface RedisSentinel

Interface for sentinel commands

Functions

ckquorum

abstract fun ckquorum(name: String, handler: Handler<AsyncResult<String>>): RedisSentinel

Check if the current Sentinel configuration is able to reach the quorum needed to failover a master, and the majority needed to authorize the failover. This command should be used in monitoring systems to check if a Sentinel deployment is ok.

close

abstract fun close(handler: Handler<AsyncResult<Void>>): Unit

Close the client - when it is fully closed the handler will be called.

create

open static fun create(vertx: Vertx, config: RedisOptions): RedisSentinel

failover

abstract fun failover(name: String, handler: Handler<AsyncResult<String>>): RedisSentinel

Force a failover as if the master was not reachable, and without asking for agreement to other Sentinels (however a new version of the configuration will be published so that the other Sentinels will update their configurations)

flushConfig

abstract fun flushConfig(handler: Handler<AsyncResult<Void>>): RedisSentinel

Force Sentinel to rewrite its configuration on disk, including the current Sentinel state. Normally Sentinel rewrites the configuration every time something changes in its state (in the context of the subset of the state which is persisted on disk across restart). However sometimes it is possible that the configuration file is lost because of operation errors, disk failures, package upgrade scripts or configuration managers. In those cases a way to to force Sentinel to rewrite the configuration file is handy. This command works even if the previous configuration file is completely missing.

getMasterAddrByName

abstract fun getMasterAddrByName(name: String, handler: Handler<AsyncResult<JsonArray>>): RedisSentinel

Return the ip and port number of the master with that name. If a failover is in progress or terminated successfully for this master it returns the address and port of the promoted slave

master

abstract fun master(name: String, handler: Handler<AsyncResult<JsonArray>>): RedisSentinel

Show the state and info of the specified master

masters

abstract fun masters(handler: Handler<AsyncResult<JsonArray>>): RedisSentinel

Show a list of monitored masters and their state

reset

abstract fun reset(pattern: String, handler: Handler<AsyncResult<Void>>): RedisSentinel

Reset all the masters with matching name. The pattern argument is a glob-style pattern. The reset process clears any previous state in a master (including a failover in pro

sentinels

abstract fun sentinels(name: String, handler: Handler<AsyncResult<JsonArray>>): RedisSentinel

Show a list of sentinel instances for this master, and their state

slaves

abstract fun slaves(name: String, handler: Handler<AsyncResult<JsonArray>>): RedisSentinel

Show a list of slaves for this master, and their state
