| # PIP-276: Add pulsar prefix to topic_load_times metric |
| |
| # Motivation |
| |
| The metrics are all started with `pulsar_`, so that both users and operators can quickly find the metrics of the entire system through this prefix. However, due to some other reasons, |
| it was found that `topic_load_times` was missing the prefix, so want to get it right. |
| |
| # High Level Design |
| |
| In master branch, keep the old metric `topic_load_times` and add below new metrics: |
| |
| * `pulsar_topic_load_times` |
| |
| After release-3.1.0, remove ``topic_load_times`. |
| |
| |
| ### Metrics |
| |
| Add new metrics: |
| |
| * `pulsar_topic_load_times` : The topic load latency calculated in milliseconds |
| |
| # Monitoring |
| |
| After this PIP, users can use `topic_load_times` and `pulsar_topic_load_times` to monitor topic load times. |
