Redundancy in logging "Flushing buffer at interval"

Elastic Stack Logstash

I am seeing below logs being displayed continuously in debug mode. What may be the issue?

 Flushing buffer at interval {:instance=>"#<LogStash::Outputs::ElasticSearch::Buffer:0x357b290a @operations_mutex=#<Mutex:0x3bbcd1d5>, @max_size=500, @operations_lock=#<Java::JavaUtilConcurrentLocks::ReentrantLock:0x3f83427a>, @submit_proc=#<Proc:0x165e8ecd@/installdir/ELK/logstash-2.2.0/vendor/bundle/jruby/1.9/gems/logstash-output-elasticsearch-2.4.1-java/lib/logstash/outputs/elasticsearch/common.rb:55>, @logger=#<Cabin::Channel:0x3b94904a @metrics=#<Cabin::Metrics:0x41cd5277 @metrics_lock=#<Mutex:0x6a7bc668>, @metrics={}, @channel=#<Cabin::Channel:0x3b94904a ...>>, @subscriber_lock=#<Mutex:0x6e356cf3>, @level=:debug, @subscribers={18942=>#<Cabin::Outputs::IO:0x5ac91d15 @io=#<IO:fd 1>, @lock=#<Mutex:0x6e35d8a2>>}, @data={}>, @last_flush=2016-03-09 05:42:49 -0500, @flush_interval=1, @stopping=#<Concurrent::AtomicBoolean:0x4b31c7aa>, @buffer=[], @flush_thread=#<Thread:0x6e04cc24 run>>", :interval=>1, :level=>:debug, :file=>"logstash/outputs/elasticsearch/buffer.rb", :line=>"90", :method=>"interval_flush"}

There is no issue. This is a debug-level log message indicating that the elasticsearch output plugin is about to attempt to flush whatever is in its buffer.

The above message is rolling 4-5 times per second.. is it fine?

Due to this I am not seeing anything in kibana

What does your elasticsearch output configuration look like?

What makes you draw the conclusion that they're related? Does Kibana work fine if you shut down Logstash?

I was wrong. This was not the issue; created another index and worked
