How to handle Multi Value Labels

[Srihari Jonnalagadda]

Hi,

Consider a hypothetical scenario of monitoring the memory usage of service in an environment of an application. So we can have mem_usage as metric and labels as service, environment, application. Let's say each service can be owned by one or more teams, how to bring in this new dimension of teams into labels so that I can query what is the memory usage by teamA and teamB separately considering a service can be owned by both teams A & B?

Have a separate metric which relates instances to teams, and join in your query.  Details here:
