Hello,
I'm sending this email for asking about the work in integrating OSprofiler into
Aodh & Panko.
Currently, there are some patches related to this work, and they are waiting
for review:
1. Aodh: https://review.openstack.org/#/c/483268/
2. Aodh client: https://review.openstack.org/#/c/484295/
3. Panko: https://review.openstack.org/#/c/483848/
4. Panko client: https://review.openstack.org/#/c/484294/
FYI, OSprofiler provides functionality to generate a trace per request, that
goes through all involve services.
This trace can visualize flow of a request [1] [2].
A trace from OSprofiler can help us know these things:
- Performance bottle-neck of a service
- Trouble-shooting issue in a service
- Understanding flow of a request (from cli client or other client)
- Trace can be store in persistent storage
- Visualization trace flow in many OpenTracing compatible tracer [2] (will
be done soon)
- Head, tail-based sampling for reducing overhead [3]
- Asynchronous tracing [4]
OSprofiler has already been in most of main OpenStack services such as: Nova,
Neutron, Keystone, Glance, and Cinder...
Hope that it will receive reviews from you all.
Thanks!
