Previously used logentries and papertrail, but they became expensive as our log volumes got larger and flexibility was missing. Now we use self-hosted ELK (elasticsearch, logstash, & kibana) and I'm not itching to go back to any of the hosted services. It's not as good as something like papertrail for tailing log streams live (although that isn't very useful at larger scale) and the UI of Kibana does take a bit of getting used to though.
