Instance Method Details

- (self) ckquorum(name = nil) { ... }

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.

Parameters:

  • name (String) (defaults to: nil)
    master name

Yields:

  • Handler for the result of this call

Returns:

  • (self)

Raises:

  • (ArgumentError)

    return self
  end
  raise ArgumentError, "Invalid arguments when calling ckquorum(#{name})"
end

- (void) close { ... }

This method returns an undefined value.

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

Yields:

Raises:

  • (ArgumentError)

  end
  raise ArgumentError, "Invalid arguments when calling close()"
end

- (self) failover(name = nil) { ... }

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)

Parameters:

  • name (String) (defaults to: nil)
    master name

Yields:

  • Handler for the result of this call

Returns:

  • (self)

Raises:

  • (ArgumentError)

    return self
  end
  raise ArgumentError, "Invalid arguments when calling failover(#{name})"
end

- (self) flush_config { ... }

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.

Yields:

  • Handler for the result of this call

Returns:

  • (self)

Raises:

  • (ArgumentError)

end

- (self) get_master_addr_by_name(name = nil) { ... }

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

Parameters:

  • name (String) (defaults to: nil)
    master name

Yields:

  • Handler for the result of this call

Returns:

  • (self)

Raises:
