Syslog has very detail key name sand namespacing (http://www.iana.org/assignments/syslog-parameters/syslog-par...) which can be filled in with application related data and this can be then parsed by any PaaS logging platform / OSS logging tool

I think syslog is a widely accepted log format and most of the tools which revolve around log metrics do support syslog and more so with parsing tools
