Detailed Description

Collects a few specific statistics variables related to Rewriting.

Member Function Documentation

Variable* net_instaweb::RewriteStats::page_load_count ( )

inline

Note: page_load_count is a misnomer, it is really beacon count.

Todo:

TODO(sligocki): Rename to something more clear.

Waveform* net_instaweb::RewriteStats::thread_queue_depth ( RewriteDriverFactory::WorkerPoolCategory  pool )

inline

Returns a waveform object for recording the current thread-queue depth. Note: for servers that don't support waveforms, null will be returned.

Member Data Documentation

const char net_instaweb::RewriteStats::kSuccessfulDownstreamCachePurges[]

static

Variable tracking number of downstream cache purges that were successful (200s).
