#!/bin/bash -x
# Do some performance related information gathering for placement.
EXPLANATION="
This output combines output from placeload with timing information
gathered via curl. The placeload output is the current maximum
microversion of placement followed by an encoded representation of
what it has done. Lowercase 'r', 'i', and 'a' indicate successful
creation of a resource provider, inventory and aggregate. If
there are upper case versions of any of those letters, a failure
happened for a single request. The letter will be followed by the
HTTP status code and the resource provider uuid. These can be used
to find the relevant entry in logs/screen-placement-api.txt.gz.
Note that placeload does not exit with an error code when this
happens. It merely reports and moves on. Under correct circumstances
the right output is a long string of 3000 characters containing
'r', 'i', 'a' in random order (because async).
After that are three aggregate uuids, and then the output
of two timed curl requests.
If no timed requests are present it means that the expected number
of resource providers was not created. At this time, only resource
providers are counted, not whether they have inventory or aggregates.
