[Q] What's the advantage of using tag based metrics over normal metrics?

[abdulj8]

We have millions of metrics and we looked at tags to see if moving out instance-related nodes from metric names to tags would reduce the number of metrics and consequently also the number of whisper db files. Looks like that is not the case, as it's creating files for each metric name and tag-value combination.

So, what is the advantage of using tags over normal metrics?

Indeed, tags are quite artificial for Graphite, so, not providing any significant value if using whisper as storage IMO. Compatible systems (e.g. graphite-clickhouse) using it, when not saving metric per file.
