Containerize the runtime events in a ring buffer.

[matttproud]

To enable someone to use this tool to observe event streams over sliding windows of sample recency as well as prevent unbound growth of observations, the list of observations has been wrapped in a ring buffer of flag-specifiable size. This has been a tremendous help in visualizing events from particularly garbage collector-active servers.

Thanks. I'll take a look tonight On 13 Jul 2014 23:01, "Matt T. Proud" [email protected] wrote:

Hmm. Let me think about this. I'm not sure this pays for itself given we have the slider to zoom into a particular area of the trace.

for cases like this, you could also just stream the values into something like graphite or influxdb and visualize with something like grafana.
