Based on Yuval's yuvalif/ceph-end2end-tracing.md

In order to view traces when vstart is started on a remote (Sepia) node, we must (?) use SSH tunneling:

open the remote terminal with some extra parameters:

ssh -L 16686:localhost:16686 -L 8000:localhost:8000 sockeni07.front.sepia.ceph.com

Tidy Up Song

Background

Static analysis is a powerful tool when searching for code issues. It does, however, have its costs. Careful tuning is required so that the developers are not overwhelmed with "false positive" detections, while on the other hand - critical errors are not missed. It also requires simple integration into the development flow, so that new issues are continuously detected and addressed.

In this project we use clang-tidy for automated static analysis
