Kibana only display logo no content -elasticsearch error shard

im new to the elastic search,
we use it to capture cisco callmanager cdr record. but it seems stop working recently.
it keeped 2yr of data.

could you please help to get it working again? tried restart the ubuntu server and restart the all three services logstash/kibana/elasticsearch.

log file is saved in /home/ftp directory and it seems everytime i restart the elasticsearch the log is being processed and removed from the FTP location.

but the main problems is the kibana is not showing any content.

could you please help, could you please also let me know the command to use?

That's a HUUUUUGE number of shards for a single node and likely causing you a lot of problems.
You should look to reduce that down to a few hundred using the _shrink or reindex APIs.

Please also format your code/logs/config using the </> button, or markdown style back ticks. It helps to make things easy to read which helps us help you :slight_smile:

thanks for the quick reply
will try follow this first

my index are done daily and name as lcch-cisco-2019.04.01

do you have a quick command reference guide for this to reduce the shards?

thanks in advance

How big are the indices?

i think 60mb a day for 2yrs, about 42Gb ..

Thanks for using the format button there, made it heaps easier for me to read :smiley:

Ok you're probably best off using the _reindex API to merge some of these into monthly with a single shard. So something like;

PUT lcch-cisco-2018.03

POST _reindex
  "source": {
    "remote": {
      "host": "http://localhost:9200"
    "index": "lcch-cisco-2018.03.*"
  "dest": {
    "index": "lcch-cisco-2018.03"

Note that this assumes you have a template for the index pattern lcch-cisco-*, otherwise when you create the lcch-cisco-2018.03 index, apply your own mapping manually.

this is awesome,

im relaying on COPY AS CURL in the help website quite a bit. anywhere i can convert your code to curl?

Ahh yeah, that's from the Dev Tools Console (which I would recommend using if you have Kibana).

If you replace the PUT with curl -XPUT IP:9200/, then add the API/index after it and then your json.

really sorry to be a pain, kibana is so broken when i click on the dev tools, it show nothing on the right

i have tried below but getting error based on here and your code

curl -X POST "localhost:9200/_reindex" -H 'Content-Type: application/json' -d'
  "source": {
    "index": "lcch-cisco-2018.03.*"
  "dest": {
    "index": "lcch-cisco-2018.03",

curl -XPUT localhost:9200/lcch-cisco-2018.03 -H 'Content-Type: application/json' -d'

POST _reindex
  "source": {
    "remote": {
      "host": "http://localhost:9200"
    "index": "lcch-cisco-2018.03.*"
  "dest": {
    "index": "lcch-cisco-2018.03"

i think i got it

curl -X POST "localhost:9200/_reindex" -H 'Content-Type: application/json' -d'
  "source": {
    "index": "lcch-cisco-2019.06.*"
  "dest": {
    "index": "lcch-cisco-2019.06"

but errors

What is the state of that new index, it looks like it's unassigned?

Trying to reindex when some of the indices you are migrating from are in a red state wll either fail or provide incorrect results. You may need to close and/or delete indices in order to bring the cluster to at least a yellow state before you can reindex. Another option might be to temporarily reduce the number of shards by setting the number of replicas to 0, which might help the cluster recover faster.

Once you have got your cluster sorted out I would also recommend upgrading. Newer versions have limits on the number of shards per node which would provide you with a warning before you got into a state like this.

thank you so much to both Christian and warkolm for quick reply and good directions.

i managed to have the system back and running by close 2017 and 2018 log first and reindexing to monthly.

code below if anyone having simliar issues.

just wanna ask, for upgrade is it just simply ##apt upgrade? from 6.4 to 7.1?

curl -X POST "localhost:9200/lcch-cisco-2019.02.*/_close"
curl -X POST "localhost:9200/lcch-cisco-2017*/_close"
curl -X POST "localhost:9200/my_index/_open"

curl -XGET 'localhost:9200/_cluster/health?pretty'

From <> 

curl -X POST "localhost:9200/_reindex" -H 'Content-Type: application/json' -d'
  "source": {
    "index": "lcch-cisco-2019.03.*"
  "dest": {
    "index": "lcch-cisco-2019.03"

Make sure you are deleting the old daily indices too :slight_smile:
