The pirate on crack output of placeload can be confusing so this change adds a prefix to the placement-perf.txt log file so that it is somewhat more self-explanatory. This change also pins the version of placeload because the explanation is version dependent. Change-Id: I055adb5f6004c93109b17db8313a7fef85538217

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.
