I push all my logs into logstash->elasticsearch. For metrics I go Riemann->Graphite. Riemann comes with a graphite compatible server so I push straight to that for processing and alerting. I also send from Riemann to logstash and logstash to Riemann where it makes sense. For my metrics dashboard I use Grafana which is really awesome. I make use of its templating pretty heavily as I run a lot of individual IIS clusters. I can create cluster overview and drill down dashboards and template it so I can just change the cluster number to see its stats. You can also link directly into a dashboard passing variables as a query string parameter. Pretty excellent.
