exclude a metric if it contains a dash

[azr]

this fixed #93 for us :)

That would fix it 👍

But what about instead changing the metric name and replace the - with _ ?
In that way the metric is still exposed and available to users.

You could replace this line here:
https://github.com/azr/redis_exporter/blob/02859cc0fec36f8d529ccbcb9a16f8456f38d937/exporter/redis.go#L394
with something like

metricName := sanitizeMetricName(split[0])

and

func sanitizeMetricName(n string) {
    // replace "-" with "_" in n 
    // and maybe other characters?
    return n
}

[azr]

Yup, looks better like this :)

But that redis_cluster_stats_messages_auth-ack_received metric is still there

[oliver006]

Hmm, no idea why that is.

I just tried to reproduce that but don't see that error on Redis 3.2.8 - what redis version are you using and what's your cluster setup?
