interface RedisSentinel
Interface for sentinel commands
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. |
|
abstract fun close(handler: Handler<AsyncResult<Void>>): Unit
Close the client - when it is fully closed the handler will be called. |
|
open static fun create(vertx: Vertx, config: RedisOptions): RedisSentinel |
|
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) |
|
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. |
|
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 |
|
abstract fun master(name: String, handler: Handler<AsyncResult<JsonArray>>): RedisSentinel
Show the state and info of the specified master |
|
abstract fun masters(handler: Handler<AsyncResult<JsonArray>>): RedisSentinel
Show a list of monitored masters and their state |
|
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 |
|
abstract fun sentinels(name: String, handler: Handler<AsyncResult<JsonArray>>): RedisSentinel
Show a list of sentinel instances for this master, and their state |
|
abstract fun slaves(name: String, handler: Handler<AsyncResult<JsonArray>>): RedisSentinel
Show a list of slaves for this master, and their state |
