In accordance to our Release Policy we’re proudly present release 19.4.

19.4 release contains of 394 bugfixes, optimisations and improvements. Refer to the Release Notes for details.

Highlights

Python3 Compatibility Statement

Python3 compatibility was one of primal focuses during 19.4 release cycle. We made lots of code reviews and cleanups to improve py3 compatibility. NOC 19.4 is able to perform test suite both on Python 2.7 and Python 3.6 and most of functions work on py3, though some glitches still remain. So we continue routine work on reaching full py3 compatibility.

We expect that:

• NOC 20.1 will have full py3 compatibility and will allow to choose between py2 and py3 during deploy.
• NOC 20.2 will by py3-only release with all py2-compatibility stuff removed.
• NOC 20.3 will use py3 features like async/await and will switch from tornado to FastAPI.

Extended MAC discovery

Discovery got extended MAC (xmac) discovery method, showing good results in linking dumb terminal equipment like CPE’s, IP Phones, IP cams, which have no other reliable discovery methods.

See #1071 for details.

DataStream improvements

IPAM got VRF, Prefix and Address streams allowing to expose all IPAM data to external systems.

managedobject DataStream got additional tags attribute exposing ManagedObjects’s tags. Tags allow to pass unstructured metadata to external system.

managedobject DataStream also exposes comprehensive VPN information.

nbi improvements

NBI got 3 additional groups of API:

• objectstatus for online Managed Object status requesting
• config and configrevisions for accessing Managed Object’s config
• path - the swiss-army knife for network topology paths calculation

time_delta in metrics

Discovery writes time elapsed from previous check to time_delta field, allowing to store metrics deltas instead of speed, allowing to perform tasks like traffic calculation and robust error detection.

Network Map Search

Objects can be searched and centered on network map which can be helpful on large maps.

Compare Configs

Configs from different managed objects can be compared via UI

BI improvements

Amount of reboots, outages, STP topology changes are added to Managed Objects’ BI statistics allowing additional problem drill-down vectors.

ICQ sender

Additional icqsender service allows to push notifications via ICQ messenger.

Development Process Changes

py3 tests

Python3 tests are mandatory now and all test suite must pass python3 testings stages as well.

Mypy integration

NOC adopts Mypy. Though mypy tests are still advisory developers are urged to add type annotations to new and to the refactored code.

Code Formatting

NOC adopts Prettier <https://prettier.io/>_ for JS, JSON, CSS and YAML code formatting. CI pipeline checks code formatting of changed files. Any misformatting considered the error and CI pipeline fails at the lint stage. We recommend to add Prettier formatting to git’s pre-commit hook or to the IDE’s on-save hook.

Docker container is also available. Use::

docker run --rm \
    -w /src \
    -v $PWD:/src \
    registry.getnoc.com/infrastructure/prettier:master \
    /usr/local/bin/prettier --config=.prettierrc --write <file name>
