重新编译zookeeper_exporter源码，构建镜像

1.github

https://github.com/dabealu/zookeeper-exporter

 

2.dockerfile

FROM golang:1.17
ENV GO111MODULE=on \
    GOPROXY="https://goproxy.cn,direct"
COPY zookeeper-exporter-0.1.12 /apps/zookeeper-exporter-0.1.12
WORKDIR /apps/zookeeper-exporter-0.1.12
#在没有go.mod的情况下执行
RUN go mod init zookeeper-exporter
#更新go.mod，可以不执行
#RUN go mod tidy
RUN go build -v
RUN cp /apps/zookeeper-exporter-0.1.12/zookeeper-exporter /usr/local/bin/zookeeper-exporter
WORKDIR /apps/zookeeper-exporter-0.1.12
ENTRYPOINT  ["/usr/local/bin/zookeeper-exporter"]

 

3.如果上面这个zookeeper-exporter在prom的页面出现unsupported character in float的问题（暂时没找到具体原因），可以换一个zookeeper-exporter试试

上图的的指标是zk_max_分区_write_per_namespace拼接而来的，其中分区为服务在zk中注册的分区。

 因为拼接后的指标zk_max_$SaturnSelf_write_per_namespace带有特殊字符$，导致prometheus无法解析
