Trying to upload a csv to an index fails

I am trying to load a csv file to an index associated with ILM policies, the first time it was executed it was successful, then I have deleted and recreated the index and the load has not worked again.

This is the pipeline.

input {
  stdin {
  file {
    path => "C:/Desarrollos/pruebas/file.csv"
    start_position => "beginning"
filter {
  csv {

output {
  elasticsearch {
    hosts => ["http://localhost:9200"]
    ilm_rollover_alias => "pac_demo"
    ilm_pattern => "000001"
    ilm_policy => "pac_demo_policy"


and this is the lifecycle policy:

  "pac_demo_policy": {
    "version": 1,
    "modified_date": "2022-09-22T14:05:24.841Z",
    "policy": {
      "phases": {
        "hot": {
          "min_age": "0ms",
          "actions": {
            "rollover": {
              "max_age": "1d"
        "delete": {
          "min_age": "7d",
          "actions": {
            "delete": {
              "delete_searchable_snapshot": true
    "in_use_by": {
      "indices": [
      "data_streams": [],
      "composable_templates": [

Hi @alter1

That is because logstash keeps track of what it has already loaded and that is stored in the sincedb

So if you want to reload a file you need to do 1 of 2 things.

1 - Clean up the sincedb by removing the file ... it is in your losgstash.log

delete this file you will need to do this after each run ...


2 - set the following in the input section which then will not keep track and the fille will be reloaded each time you start logstash. The is a good way during Dev / Test Cycle
sincedb_path => "NUL"
