### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Motivation Currently, we have topic load-related metrics like the followings: ``` topic_load_times{cluster="standalone",quantile="0.5"} 140.0 topic_load_times{cluster="standalone",quantile="0.75"} 183.0 topic_load_times{cluster="standalone",quantile="0.95"} 249.0 topic_load_times{cluster="standalone",quantile="0.99"} 249.0 topic_load_times{cluster="standalone",quantile="0.999"} 249.0 topic_load_times{cluster="standalone",quantile="0.9999"} 249.0 topic_load_times_count{cluster="standalone"} 6.0 topic_load_times_sum{cluster="standalone"} 955.0 topic_load_times_created{cluster="standalone"} 1.671240308864E9 ``` But we are not able to detect if there are topics that failed to load due to zookeeper/bookkeeper problems. It's better to add new metrics for the topic load failed operation so that users can add alerts based on the metrics. ### Solution Add `topic_load_failed_count` metrics ### Alternatives _No response_ ### Anything else? The metrics changes requires a proposal ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
