Output is being truncated even output_truncate: -1 is set

[Ared8]

With this config (trying to get full config from a switch) for each execution the length of the output is different, sometimes outputs everything and sometimes output is truncated

modules:
show_full_config:
user: XXX
password: XXX
command: "show run view full | begin Current"
timeout: 60
output_metric: true
output_truncate: -1

using last version 1.5.0

When the output is truncated, does it end with ...? The code will return the full string when the truncate is -1:

ssh_exporter/collector/collector.go

Lines 267 to 271 in bdea915

	func truncateString(str string, num int) string {
	bnoden := str
	if num == -1 {
	return bnoden
	}

If the truncated output does not contain the ... suffix then the truncation code isn't the cause. It might be there is a timeout occurring if the output is very large.

FWIW this exporter is designed to validate SSH is healthy and the output is intended to validate that SSH login was successful, ie execute uptime to validate got valid SSH login session. For something like downloading full switch configs, there are tools like oxidized: https://github.com/ytti/oxidized.
