 说起来挺偶然的，结识hertzbeat是因为我大学的毕业设计，当时在一家互联网公司实习，那个时候第一次看到了企业是怎么监控项目的，不管是系统监控、业务监控还是物联网iot监控，那个时候见世面不广，只知道Prometheus + Grafana，但是学起来、用起来成本比较高，那个时候就觉得应该有其他类型的监控，恰好，到了大学毕业设计选题，我就开始寻找这方面的开源项目，那个时候我们小组正在使用Shen Yu网关，我就看了下社区，发现了hertzbeat，自此我便于它结缘了。

 In March 2023, I noticed Hertzbeat's project, so I directly sent an email to Tom in the community to ask if I could join, and he replied very quickly. It just so happened that I was in my senior year of college when I had more time, so I decisively picked an issue to resolve and had my first pull request at Hertzbeat.

 In the following period, I spent some time reading Hertzbeat's code, and submitted a few PRs off and on until April, when I learned about the Summer of Open Source event, and it just so happened that Hertzbeat was participating as well, so I submitted my application information and was selected. My task is mainly responsible for the implementation of a push collector, in the process of writing the code, I got a lot of community mentor Zheng Chenxin and Tom to help, and finally was able to successfully complete the code, the whole process is still relatively smooth.

 - When you first get involved in an open source project, start with simple tasks. Gradually familiarize yourself with the code and process of the project, and gradually take on more complex tasks.
 - If you encounter problems that you can't solve by yourself, you can ask for help from the community.

 In April of this year, when HertzBeat entered the Apache Incubator, I happened to see a recommendation on a WeChat public account in my social circle.
 
 My first reaction was that the name was really well chosen 😄. Then, after looking closely at the features it provides and the problems it solves, I realized its powerful functionalities 💪.
 
 Since I also need to maintain an observability system at my company, and I have participated in an open-source project called cprobe (which has some similar goals to HertzBeat), I have some experience with monitoring systems and a strong interest in them. Therefore, I read the documentation and quickly started it locally (the community has done a great job in this regard, as many open-source projects lose potential developers right at the initial startup step).
