------------------------------------------------------------------------
btw, in practice, ThresholdFilter would be set at least to WARN, I do not think
there is a lot of added value to go through INFO logs, why would you? There is
other telemetry for that, diagnostic events, jmx metrics ... but WARN or ERROR
would be nice to see for sure. So there will not be a lot of WARNs or ERRORs in
runtime, a magnitude less than INFO. It would take quite a buggy node to fill
that buffer with WARN or ERROR only.
More to it, from CASSANDRA-16806 it is possible to TRUNCATE / DELETE on
vtables. So if you find the buffer full or your are not interested in that
anymore you can just truncate and clear that buffer completely.

> Project: Cassandra

> The warnings and errors are currently only accessible through Cassandra logs.
> Automating the monitoring of the nodes would be much easier/secure if we can
> make use of virtual tables to get the logs.
