The http input plugin acts as a server and processes incoming requests. It looks like you might be looking for the http poller plugin, which is able to periodically collect data from HTTP endpoints.

Thanks Christian,
I was using http_poller thus :

input {
http_poller {
urls => {
test0 => "http://agromet.inia.cl/api/emas/?user=adbdb1ef0dca1ad"
#test1 => {
# Supports all options supported by ruby's Manticore HTTP client
#method => "get"
#url => "http://agromet.inia.cl/api/emas/"
#auth => {
# user => "adbdb1ef0dca1ad"
# password => ""
#}
#}
}
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"
}
}
Only is working Test0, Test1 connect but no return data.
I think Test1 must be run because both are doing the same or not?
Regards & thanks again
