* Add osprofiler wsgi middleware. This middleware is used for 2 things:
1) It checks that person who wants to trace is trusted and knows
secret HMAC key.
2) It starts tracing in case of proper trace headers
and adds first wsgi trace point, with info about HTTP request
* Traces HTTP API calls
* Traces DB (SQLAlchemy) calls
Demo: https://tovin07.github.io/panko/openstack-event-list.html
HOW TO TEST?
1. Install devstack with panko as usual
2. Install osprofiler
pip install osprofiler
3. Add these line to /etc/panko/panko.conf
[profiler]
enabled = true
hmac_keys = SECRET_KEY
connection_string = redis://localhost:6379 # example when using redis
4. Pass HMAC_KEYS to client commands
- panko client with `--profile <HMAC_KEYS>`
- openstack client with `--os-profiler <HMAC_KEYS>`
Output will look like this:
To display trace use the command:
osprofiler trace show --html <TRACE_ID>
5. Use osprofiler to get the trace
osprofiler trace show \
--connection-string redis://localhost:6379 \
--out out.html \
--html <TRACE_ID>
6. Open that html file with browser and view the result
