I think this is going to act a little strange if the tls.Config isn't created succesfully, because the second time Gather is called it will not return an error here. You may want to look at the nginx input for a good example.

You can use internal.GetTLSConfig to do this: https://github.com/influxdata/telegraf/blob/master/internal/internal.go#L118

Could you remove the ResponseHeaderTimeout and only use the Timeout on http.Client?

@Soulou do you have time to address the changes requested by Daniel? |

My apologies for the delay, @glinton. I'm going to do them before the end of August |

Sorry to pester you @Soulou, but just looking for an update. Thanks |
…dpoints Goal: A completely secure NSQ doesn't have any HTTP endpoint, but only HTTPS, often with x509 client authentication. This PR aims at configuring the HTTP client to correctly connects to nsqd Choices: TLS configuration build is only done once, and the first `Gather()` will return an error, if configuration is invalid, then it will be silent. The HTTP client is only built once, to limit allocations
