How to set indices.lifecycle.poll\_interval?  
Read that it a cluster level setting.

Thanks and regards

You can change the ILM poll interval if needed:

```auto
PUT _cluster/settings
{
  "transient": {
    "indices.lifecycle.poll_interval": "5s"
  }
}

```

But I'd not do this in production as the default values seem reasonable to me.

Note that I used `transient` here. So it won't survive a cluster restart.  
Use `persistent` of you want it to be persistent.

Thanks sir,  
I was planning to test the ILM policy that I created with indices of small sizes as roll over condition . So this setting may be helpful for that.

Hi @shi

Let me save you a little trouble ... testing lifecycle with small indices and small times, and small sizes will will not perform "Exactly" as you expect there have been a number of threads on this...

See [Here](https://discuss.elastic.co/t/ilm-rollover-not-working-on-max-size/287999/4) and [Here](https://discuss.elastic.co/t/question-about-index-rollover/207452)

Not to say you can not test... but if you expect indices to rollover at _ **exactly** _ 50MB they will not... Rollover is a background task... ILM is geared to work on indices that of sizes of GBs, hours, days etc... not MB and Minutes.
