I am following this link (Link) to display live weather data on Kibana. I am using logstash to stash the live data into elasticsearch.

I used the logstash configuration explained in the pdf.

Here is my logstash configuration:

input {
  exec {
    command => "curl --silent -L ’http://api.openweathermap.org/data/2.5/weather?id=5490223&appid=my_api_key&units=metric’"
    codec => "json"
    interval => 600
  }
}
filter {
  mutate {
    remove_field => ["@version" ,"command" ,"host" ,"cod" ,"id" ,"base" ,"coord" ,"sys" ,"dt"]
  }
  split { field => "weather" }
}
output {
  elasticsearch {
    hosts => ["localhost:9200"]
    index => "weather-%{+YYYY.MM.dd}"
  }
}

When I execute, I get an error like this

You copied the configuration from source, which, based on your editor preference, replaced ' U+0027 : APOSTROPHE {APL quote} by U+2019 : RIGHT SINGLE QUOTATION MARK {single comma quotation mark}. Please read Right single apostrophe vs. apostrophe? on why its different.

In your command => "curl --silent -L ’http://api.openweathermap.org/data/2.5/weather?id=5490223&appid=my_api_key&units=metric’"

you need to replace by ', or manually write the entire url instead of copying it
