* add jaeger support, link hot container & req span * adds jaeger support now with FN_JAEGER_URL, there's a simple tutorial in the operating/metrics.md file now and it's pretty easy to get up and running. * links a hot request span to a hot container span. when we change this to sample at a lower ratio we'll need to finagle the hot container span to always sample or something, otherwise we'll hide that info. at least, since we're sampling at 100% for now if this is flipped on, can see freeze/unfreeze etc. if they hit. this is useful for debugging. note that zipkin's exporter does not follow the link at all, hence jaeger... and they're backed by the Cloud Empire now (CNCF) so we'll probably use it anyway. * vendor: add thrift for jaeger

# SYNOPSIS
|
|
#
|
|
# AX_CHECK_OPENSSL([action-if-found[, action-if-not-found]])
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Look for OpenSSL in a number of default spots, or in a user-selected
|
|
# spot (via --with-openssl). Sets
|
|
#
|
|
# OPENSSL_INCLUDES to the include directives required
|
|
# OPENSSL_LIBS to the -l directives required
|
|
# OPENSSL_LDFLAGS to the -L or -R flags required
|
|
#
|
|
# and calls ACTION-IF-FOUND or ACTION-IF-NOT-FOUND appropriately
|
|
#
|
|
# This macro sets OPENSSL_INCLUDES such that source files should use the
|
|
# openssl/ directory in include directives:
|
|
#
|
|
# #include <openssl/hmac.h>
