Sysdig Tracers
Tracers is nice extension to one of my favourite tool sysdig to troubleshooting problems. Using damn simple approach of writing tags to /dev/null, give an idea about your app’s health. More performing than popular statsd to measure duration, because of low overhead ca. 1 microsecond per tracer. Moreover you can filter out some of the tracers and send them to statsd to gain better visiblity. So you can get on demand tracing insight using command line sysdig or semi-graphical interface csysdig and long term approach of exporting data to statsd. Worth to try.
