Nebula Dashboard 修改PromQL后，未生效

Reid00 · 2021 年9 月 6 日 06:28

提问参考模版：

nebula 版本：v2.0.1
部署方式（分布式 / 单机 / Docker / DBaaS）：分布式
是否为线上版本：Y
硬件信息
- 磁盘（推荐使用 SSD）
- CPU、内存信息

修改/app/assets/utils/PromQL.ts 中的query

disk_used: 'node_filesystem_size_bytes{mountpoint=~"/mnt|/mnt/data",fstype!="rootfs"} - node_filesystem_avail_bytes{mountpoint=~"/mnt|/mnt/data",fstype!="rootfs"}',
  disk_free: 'node_filesystem_avail_bytes{mountpoint=~"/mnt|/mnt/data",fstype!="rootfs"}',
  // disk_readbytes: 'irate(node_disk_read_bytes_total{device=~"(sd|nvme|hd)[a-z0-9]*"}[1m])',
  disk_readbytes: 'irate(node_disk_read_bytes_total{device=~"vdb"}[1m])',
  disk_writebytes: 'irate(node_disk_written_bytes_total{device=~"vdb"}[1m])',
  disk_readiops: 'irate(node_disk_reads_completed_total{device=~"vdb"}[1m])',
  disk_writeiops: 'irate(node_disk_writes_completed_total{device=~"vdb"}[1m])',
  inode_utilization: '(1- (node_filesystem_files_free{mountpoint=~"/mnt|/mnt/data",fstype!="rootfs"}) / (node_filesystem_files{mountpoint=~"/mnt|/mnt/data",fstype!="rootfs"})) * 100',
  disk_size: 'node_filesystem_size_bytes{mountpoint=~"/mnt|/mnt/data",fstype!="rootfs"}',

修改后的每个query 我都在Prometheus 中check 了，可以查询到，如下

npm run stop
npm run start

观察到Disk 相关的监控还是没有发生变化，如下，是还需要修改什么参数吗？

改完有重新build，重新部署么？

Reid00 · 2021 年9 月 6 日 06:57

没有重新build，只是重启了服务，要重新build？

jerry.liang · 2021 年9 月 6 日 07:06

对的，因为我们用了typescript语法，需要重新build一下

Reid00 · 2021 年9 月 6 日 08:20

@jerry.liang 我要继续问一下了，7003 端口不能访问，步骤如下:
我clone 了https://github.com/vesoft-inc/nebula-dashboard 最新的代码

vendor folder下添加了nebula-http-gateway 重新启动
现在8090、9090、9100、9200 服务都已经正常启动
修改了static/custom.json的配置如下：

{
    "connection": {
        "ip": "10.0.7.140",
        "port": 9669
    },
    "alias": {
        "ip:port": "instance1"
    },
    "chartBaseLine": {

    }
}

github install，启动命令如下, 不再是npm run start，dev 的端口是7003

$ npm install
$ npm run dev

报错：

如果npm run start 启动端口7001, 不报错，但是浏览器访问

Internal Server Error, real status: 500

看了proxy.ts 并没有写死

System limit for number of file watchers reached, 看起来像是文件数太多了，试试这个react项目启动报错：Error: ENOSPC: System limit for number of file watchers reached-CSDN博客

Reid00 · 2021 年9 月 6 日 10:25

感谢，这个问题解决了，但是npm run dev 之后前端一直再加载中，而且npm run dev 不是daemon 进程

Reid00 · 2021 年9 月 6 日 11:06

重新安装依赖，npm install, npm run tsc,npm run build,npm run start这样一套

jerry.liang · 2021 年9 月 6 日 15:46

嗯嗯，npm run dev是运行开发环境，daemon的是npm run start
