Get Total Commands Processed in Redis Using Python (Detailed Guide w/ Code Examples)
The total commands processed statistic in Redis can be used to monitor the workload of a Redis instance. It represents the total number of commands processed by the server since it started. This is useful in performance monitoring and debugging.
Using redis-py, a Python client for Redis:
r = redis.Redis(host='localhost', port=6379, db=0)info = r.info()print(info['total_commands_processed'])
In this example, we connect to a Redis server running on localhost at port 6379. Then, we call the info method which returns a dictionary containing information and statistics about the server. We then print the 'total_commands_processed' value from this dictionary.
Always ensure that the Redis instance is up and running before trying to fetch stats.
Handle exceptions that may occur during the connection with Redis or if the stat does not exist.
Not checking the availability of Redis server: Make sure Redis server is running and accessible.
Misunderstanding the meaning of commands processed: This indicates the total number of commands processed since the Redis server started, not the currently active commands.
What does 'total_commands_processed' represent?
It represents the total number of commands processed by the Redis server since it started.
Is 'total_commands_processed' reset on Redis restarts?
Yes, it's reset every time the Redis server is restarted.
