Because APM collects performance monitoring data about each request or
job execution, this results in a large amount of additional data being
sent to Sentry. For this reason, APM is off by default, and the rate of
sampling is configurable in a setting.
Settings related to this change:
- `sentry_backend_traces_sample_rate`: the APM sample rate, with a
default value of 0.0 (max value 1.0, although this isn't recommended)
refs DE-922
flag=none
test plan:
- ensure you have Sentry running at sentry.docker and have a DSN
configured in `config/sentry.rb`
- confirm that, by default:
- no traces appear in the "Performance" section
- change the `sentry_backend_traces_sample_rate` setting to `1.0`
- restart rails and job servers
- confirm that:
- traces now appear in the "Performance" section for both controller
and job executions
- for jobs, traces and contain context from the job under the
"INST-JOBS"section
- remove `config/sentry.yml` and restart rails and jobs servers
- confirm that the app/jobs start fine and there are no issues
