hyphens in metric names causing scrape failures

[jpiper]

In the latest clickhouse version, clickhouse is exporting metrics about devices, and this is generating metric names with hyphens in them, which are not valid for prometheus and scraping fails

# HELP clickhouse_block_active_time_dm-0 Number of BlockActiveTime_dm-0 async processed
# TYPE clickhouse_block_active_time_dm-0 gauge

I have no idea how it can happen, because on clickhouse server side we replace all chars except a-zA-Z0-9_: in metric name to _ https://github.com/ClickHouse/ClickHouse/pull/26140

Could please you provide server version and config to reproduce problem?

UPD: got it, problem is connected to golang code in clickhouse_exporter and not related to embedded exporter
