Regex support in elasticsearch metrics alias pattern

[soltiz]

Metrics field are often longer than wished in a legend.
Example: topbeat ==> "cpu.idle", "cpu.system", "cpu.user", "cpu.nice"

a regex in alias pattern (like {{regex /cpu.(.*)/}} ) would allow more readible series names (here, only "idle", "user", "system"). This is especially powerful if we can chain it with {{term fieldname}} so as to transform terms values !!!

Same. I have lookup values in my index. e.g. 1, 2 ,3. While I could create a new index, I think I would like to be able to Regex them. 1/httpd, 2/jboss, 3/auditd

Is anyone working on this feature?
I'm interested in helping where needed.

@holiiveira you're welcome to contribute. No one else in working on this as far as I know. Please note that it's no guarantee that we'll accept your PR and/or it may take some time depending on how we see this feature fit. Right now there are no other core datasource having this feature so maybe this feature would be better to solve in a more generic way. However, how this generic way looks we don't know right now.

If you want to open a PR you'll need to solve it both client and server side to support alerting.

It's a feature that I miss a lot. For exemple, with the module jolokia from metricbeat, when using generic terms, I could have fields like "kafka.server:name=MessagesInPerSec,topic=gap,type=BrokerTopicMetricskafka.". In this case, the only discriminating thing I would like to see in legend is the name of the topic ("gap" here).

I have two ES queries, both are simple "Count" metrics, unfortunately both of their names is "Count". I believe this prevents Grafana from displaying these next to each other (they are grouped by the same "group by") - this is not an issue with InfluxDB at all since aliasBy is available. This also prevents me from using Meta Queries plugin.

Same here. Use case: My host names are stored as-is as tags in the time series databases, and I need to have a generic way to drop the domain part. :-/

This is most useful in elasticsearch, but sadly, after 4 years, still no way to do this.
While a generic way to do this in all data sources is awesome, trying to aim just for that may be harder and block this features for several years. It is better to add this just to elasticsearch and then expand or rewrite if it is found a better way
