Hi,
I need to add frequency to elastize data in my elasticsearch.
I'm using stdin input and I don't know which the parameter/variable relationated with frequency.
Somebody can help me?

not sure on your exact query.
Do you mean
- frequency of a term within data (i.e. like the [termvectors](https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-termvectors.html))
- Or is it more of frequency of data collection? How quick should you poll ?

Refresh data already stored by establishing a frequency to refresh of this data.
I obtain the data from a web service, for which if the data of the web service changes I need to update it in my logstash automatically by means of a certain elastication frequency.

Welcome to our community! 😃
What sort of data is this?

Can be json, html, xml or csv.
I'm using input stdin.

ok. So what you are looking is more like scheduling/cron type of pulling from the web-service?
If you look into the relevant [input plugins of logstash](https://www.elastic.co/guide/en/logstash/current/input-plugins.html), you will find some modules contain scheduling/cron built in
For example for a web-service, you can use [http\_poller](https://www.elastic.co/guide/en/logstash/current/plugins-inputs-http_poller.html) , but depends on what you exactly want..
Something of concept like below should be good starting point
```auto
input {
http_poller {
urls => {
webservice1 => "http://localhost:9200"
}
}
request_timeout => 60
# Supports "cron", "every", "at" and "in" schedules by rufus scheduler
schedule => { cron => "* * * * * UTC"}
codec => "json"
# A hash of request metadata info (timing, response headers, etc.) will be sent here
metadata_target => "http_poller_metadata"
}
```
}
