Data inconsistencty shown in ELK


I am running with ELK version 7.17.15.

# curl -X GET "localhost:9200"
  "name" : "ip",
  "cluster_name" : "name",
  "cluster_uuid" : "uudi",
  "version" : {
    "number" : "7.17.15",
    "build_flavor" : "default",
    "build_type" : "deb",

Till now I was focusing on indices/index name starting with filebeat-7.17.15-2024.* when I checked using the curl on a CLI interface. e.g. as below

# curl -X GET "localhost:9200/_cat/indices/filebeat-7*?v"
health status index                              uuid                   pri rep docs.count docs.deleted store.size

Currently I am seeing there index name starting with filebeat-8.10.4-2024.01.12 and filebeat-8.11.2-2024.01.12. I am not sure if I am overlooking into this pattern?

# curl -X GET "localhost:9200/_cat/indices/filebeat-8*?v"

Please someone could suggest on why?



It is not clear what is the inconsistency here and what is your issue.

If you have indices that start with filebeat-7.17.15-*, this means that you have some filebeat 7.17.15 sending logs to your cluster.

The same thing happens for indices starting with filebeat-8.*, you have some filebeat instance on these specific versions sending logs to your cluster.


Thanks, I understood.

Question: This is a single node solution and when I checked the filebeat version it specifies as below mentioned.

filebeat version

filebeat version 7.17.15 (arm64), libbeat 7.17.15 [xxxx built 2023-11-08 19:08:34 +0000 UTC]

I will check at the client end if anything or any client server has been added and has fb version 8.x installed. correct me if I am wrong here.


As mentioned, y ou have filebeat instances on version 8 sending logs to your cluster.

You can look in Kibana in the dataview for your filebeat logs and filter by the index name to know more about those logs and maybe identify the source.

Thank you @leandrojmp This helped a lot and was able to fetch the details on identifying the source and the logs path.
