Lines 444 to 455 in eb5eb94

	// Prepend a baseline lead-in that summarizes the number of certificates
	// retrieved and from which target host/IP Address.
	defer func() {
	nagiosExitState.LongServiceOutput = fmt.Sprintf(
	"%d certs found for %s%s%s%s",
	certsSummary.TotalCertsCount,
	certChainSource,
	nagios.CheckOutputEOL,
	nagios.CheckOutputEOL,
	nagiosExitState.LongServiceOutput,
	)
	}()

is included after hostname verification succeeds or fails. Instead, for troubleshooting purposes we probably want to include that just after the certificate chain is retrieved. Then, regardless whether any later checks succeed or fail we'll have the plugin output to indicate how many certs were found for what source.
