Detailed Description

Members that are constructed later, during enable().

Whereas the ServerStats is constructed early in the server startup process, these members get to access globals and globals.config in their constructors.

Event::Signal::Monitor LogCabin::Server::ServerStats::Deferred::signalMonitor

Registers signalHandler with event loop.

std::chrono::nanoseconds LogCabin::Server::ServerStats::Deferred::dumpInterval

If nonzero, the statsDumper thread will write the current stats to the debug log if this duration has elapsed since the last dump.

Definition at line 154 of file ServerStats.h.

std::thread LogCabin::Server::ServerStats::Deferred::statsDumper

This thread dumps the stats periodically and when signalled.

Dumping the stats is done from a separate thread so that the event loop thread does not acquire locks in higher-level modules (which could result in deadlocks or delays). Introduced for https://github.com/logcabin/logcabin/issues/159 .
