I have an API call to JIRA which should run only once every 4 weeks. I'm using logstash http\_poller to fetch the data from JIRA.

The schedule with http\_poller does not allow a complex cron schedule so I was planning on setting up an external cron. For this, I need the http\_poller to run only once which works with using schedule as **{"in" =\> "0"}** but logstash is not terminated after the run.

Is there a way to terminate logstash after http\_poller runs once. Or is there an alternative input plugin to fetch API data?

Use a stdin input, which will tell logstash to exit when it hits end-of-file. Then run logstash using

```
echo One line | /usr/share/logstash/bin/logstash ...

```

Use an http filter to make the API call.

Thanks a lot @Badger! I've tried to implement this solution and I'm getting the below error.

> error during HTTP request {:url=\>"URL\_with\_query\_params", :code=\>415, :response=\>""}

The call that I'm making is a GET call to JIRA REST API and here's the configuration I'm using. The URL does have query parameters and I've tried to use **query** property to define the parameters as key-value pairs but no luck.

```auto
input {
	stdin {}
}

filter {
	http {
		url => "URL_with_query_params"
		verb => "GET"
		user => "username"
		password => "password"
		truststore => "path_to_certificate"
		truststore_password => "truststore_password"
	}
}

output {
  stdout { codec => rubydebug }
}

```

Can you please review and let me know why this is not working?

A 415 response code would typically indicate an incorrect Content-Type header. You can set the header using the "headers" option...

```
http {
    headers => { "Content-Type" => "text/plain" }
    ...

```

text/plain is just an example. I do not know what the JIRA API expects.

Thanks a lot for the help @Badger! I was able to successfully implement this. JIRA API was expecting Content-Type as "application/json".
