Add OpenTelemetry integration to Redix (#29)
Initial approach follows Ecto instrumentation, recording spans for all
Redix `[:redix, :pipeline, :stop]` events.
The command sanitization is inspired-by and adapted from [Java
instrumentation][1], from where I've also copied the actual commands and
what configuration should they follow.
Network attributes are tracked via a "sidecar" process, which keeps
track of connection attributes also via `telemetry`. This extra bit of
bookkeeping is needed as command events doesn't include that piece of
information, unfortunately.

||||
attribution notices from the Source form of the Work,
|
||||

|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed

|
||||

|
||||
wherever such third-party notices normally appear. The contents
|
||||

||||
|
||||

|
||||

|
||||

|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|

of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

# OpentelemetryRedix
|
||||
|
||||
OpentelemetryRedix uses [telemetry](https://hexdocs.pm/telemetry/) handlers to
|
||||
create `OpenTelemetry` spans from Redix command events.
|
||||
|
||||
Supported events include command stop. Connection and disconnection events
|
||||
are also observed to track Redis instance address.
|
||||
|
||||
## Note on Redix integration
|
||||
|
||||
A sidecar process runs under `opentelemetry_redix` application to track
|
||||
Redix connection information to inside command spans. As a requirement, all
|
||||
Redis connections should start after this application.
|
||||
|
||||
For connections started by your application, all works as expected. But some
|
||||
libraries manage internally, and for those cases, you need to ensure proper
|
||||
order via `extra_applications`.
|
||||
|
||||
One such example is [hammer_backend_redis](https://hex.pm/packages/hammer_backend_redis).
|
||||
In case you depend on that library, `extra_applications` will be similar
|
||||
to the following:
|
||||
|
||||
```elixir
|
||||
def application do
|
||||
[
|
||||
extra_applications: [:opentelemetry_redix, :hammer_backend_redis]
|
||||
]
|
||||
end
|
||||
```
|
||||
|
||||
## Installation
|
||||
|
||||
The package can be installed by adding `opentelemetry_redix` to your list of
|
||||
dependencies in `mix.exs`:
|
||||
|
||||
```elixir
|
||||
def deps do
|
||||
[
|
||||
{:opentelemetry_redix, "~> 0.1"}
|
||||
]
|
||||
end
|
||||
```

||||
