Kibana not showing events logged by logstash in elasticsearch db


(Suraj Sharma) #1

Following are my configuration settings:-
Logstash: is used as an indexer
ElasticSearch: used to store the events and indexes them. RUNNING ON ALL
DEFAULT SETTINGS.
Kibana: Used as the GUI and is of RUBY version. RUNNING ON ALL DEFAULT
SETTINGS.

WHEN THE NUMBER OF EVENTS RECEIVED IS LESS SAY 4-5 (in past 15 mins), THE
KIBANA INTERFACE IS NOT SHOWING THEM IN THE 'LAST 15 MINUTE WINDOW'.

Here is the total test cases that i have run:-

CASE 1 : (CASE1_logstash_sent_single_event.png +
CASE1_kibana_not_showing_single_event.png)
Logstash: In this i have sent a single event (as shown in
logstash logs) to elasticsearch server.
Kibana: is also running from this and is not showing any
entry.
CASE 2 : (CASE2_logshatsh_sent_2events_per_second.png +
CASE2_kibana_not_showing_this_event.png)
Logstash: It was logging events with rate of 2 per seconds
Kibana: Kibana interface is still not showing any thing.
CASE 3 : (CASE3_logstash_sent_8events_per_second.png +
CASE3_kibana_started_showing.png)
Logstash: it started showing events with rate 8 per seconds
Kibana: It started showing all the events along with the
previous "SMALL Frequented" events.
CASE 4: (CASE4_when_i_select_to_inspect.png +
CASE4_kibana_shown_nothing_on_select.png)
WHEN I SELECT TO INSPECT THE "SMALL Frequented" EVENTS,
KIBANA AGAIN SHOWS NOTHING.

My Question: Is there a threshold or something which is controlling this...?

Also can you explain me the significance and actual need of the following
configuration options in kibana (Taken from KibanaConf.rb):-

  1. Analyze_limit (my_value=default=2000)
  2. Analyze_show (my_value=default=25)
  3. Rss_show (my_value=default=25)
  4. Export_show (my_value=default=2000)
