Kibana doesn't show any results in "Discover" tab

For people who have a problem like this:

Change time frame in top right corner.

By default it shows data only for last 15 min.

I wanted to put this as a comment but unfortunately, I am not able to given my deficient repo to do so. So as @Ngeunpo suggested, this is how you add a time field to an index while creating it:. If you did not do that while creating your index, I suggest you delete that index and recreate it. The index name logstash-* in the gif is analogous to your index applogs. In this case, field @timestamp is added as the time field. Let me know if this works.

Kibana does not understand the timestamp field, if it's format is incorrect.Timestamp, which you selected by clicking on Time-field name when Configure an index pattern, need to be :

"timestamp":"2015-08-05 07:40:20.123"

then you should update your index mapping like this:

curl -XPUT 'http://localhost:9200/applogs/1/_mapping' -d'{  "1": {    "timestamp": {      "enabled": true,      "type": "date",      "format": "yyyy-MM-dd HH:mm:ss.SSS",      "store": true    }  }}'

See this question and answer

UPDATE

If you are using ES 2.X, you can set the "format" to "epoch_millis" like this:

curl -XPUT 'http://localhost:9200/applogs/1/_mapping' -d'{  "1": {    "timestamp": {      "type": "date",      "format": "epoch_millis",      "store": true,      "doc_values": true    }  }}'
