A wrapper for redis-py, instrumented using OpenCensus for distributed tracing and metrics

Project description

ocredis is a wrapper for the popular [redis-py](

ocredis provides observability using OpenCensus for distributed tracing and metrics.

Installing it

pip install ocredis

Using it

You can initialize exactly how you would for redis.Redis. In fact it is meant to be a drop replacement.

  • Change the import statement from
>>> import redis


>>> import ocredis
  • Change the client initialization from
>>> client = redis.Redis(host=host, port=port)


>>> client = ocredis.OcRedis(host=host, port=port)`

and obviously enabling OpenCensus metrics and exporters as per

>>> ocredis.register_views()

and the rest is trivial to use then.

For example

>>> import ocredis
>>> ocredis.register_views()
>>> r = ocredis.OcRedis(host='localhost', port=6379)
>>> r.set('foo', 'bar')
>>> r.get('foo')

Metrics available

  • calls
  • latency
  • key_length
  • value_length
Metric View Name Unit Tags
Latency redispy/latency ms ‘error’, ‘method’, ‘status’
Calls redispy/calls 1 ‘error’, ‘method’, ‘status’
Key lengths redispy/key_length By ‘error’, ‘method’, ‘status’
Value lengths redispy/value_length By ‘error’, ‘method’, ‘status’


Tests can be run by using pytest, for example
