In Hyperledger Fabric, block events are provided by peers. Whenever a block is committed to a peer's ledger, that peer generates a corresponding event. These events can include the full block content or a summary of the transactions within the block, allowing applications to register and receive notifications about these events. This setup is crucial for applications that need to respond to changes recorded on the blockchain in real-time .

Yeah, "Do health check" is super common in APIs.

"Get log data" is definitely a standard feature though.

Wait, are you sure? I thought all those functions were included.

Totally agree, that seems off for an Operations Service.

I think "Set log level" is the one that's not provided.

I’m leaning towards "Do health check" being provided, but I’m not confident about "Get log data" either. This is tricky!

I feel like "Get metrics" is a common function in APIs, but I can't remember if it's specifically mentioned as part of this service.

I think we had a practice question about health checks and logging. If I recall correctly, "Set log level" might not be part of the Operations Service API.

I remember we discussed RESTful APIs in class, but I'm not entirely sure which function is unprovided.

I've seen questions like this before. The key is to identify the core functionality an operations API should provide, then eliminate the options that don't fit that profile.

Okay, let's see. The Operations Service API should provide common management functions. I'm guessing "do health check" is the one that's not typically part of that set.

Hmm, I'm a bit unsure about this one. I need to make sure I understand the difference between the options - get log data, get metrics, set log level, and do health check.

This looks like a straightforward API question. I'll focus on understanding the different operations provided and think about which one is not included.

Ah, the age-old question: 'Get log data' or 'Get metrics'? I'll go with 'Get log data' - it's like reading a novel, but with more code!

'Set log level' is also important for troubleshooting and debugging.

I prefer 'Get metrics', it gives a better overview of the system performance.

Hmm, I think 'Set log level' is the way to go. Gotta keep those logs clean and tidy, you know?

Clearly, the answer is 'Do health check'. I mean, who doesn't love a good health check? It's like a spa day for your server!

I'm not sure, but I think B) Get metrics might also be a valid option as it's not directly related to operations.
RO

I disagree, I believe the answer is D) Do health check because it's not a typical operation service API.
