The situation you describe is more an event then it is an metric, and indeed postgres is much better suited for it, if asked that is what I'd recommend for this kind of issue.
What DalmatinerDB was build of is handling high numbers of metrics like CPU usage, memory usage, etc, everything where for every point in time you have exactly 1 value. In that space it can handle millions of metrics (read millions of inserts) at the same time where a system like postgres would stat to have problems in my experience.
