stathub-go's Issues

客户端到服务器的网络不稳定时，大量重复错误日志

观察到两台位于大陆地区的客户端无法稳定地向海外服务器报送数据，日志文件中有大量错误记录行。

基本都是以下两类：

 334807行
ERROR] send stat failed, Post https://1.2.3.4:15944/api/stat: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

  67706行
ERROR] send stat failed, Post https://1.2.3.4:15944/api/stat: dial tcp 1.2.3.4:15944: connect: connection refused

因为我有一段时间没关注软件的运行情况，没及时发现并排查解决问题，所以日志增长很快。也许其他用户也可能有网络不稳定的问题，软件是否可考虑降低网络不稳定情况下的重试频率，或合并错误日志行并定时清除？

以下为错误日志的排查详情：

很不错的项目,使用了一段时间.

您在V2EX发帖的时候就有V友询问有没有 Windows client 的考虑.
https://www.v2ex.com/t/184177#r_1982552

请问有这个 Windows client 打算吗,还是说你把项目忘了哈哈哈.

是否可以支持查看监控页不需要密码？

有正确的卸载姿势吗？

服务端+客户端

Remove Node on the List

Please help how to remove nodes not needed on the list.

问一下安装客户端的时候，已经按提示安装了，但是数据没有显示在页面上

页面没有显示

客户端执行了

也没有客户端client.log日志生成是怎么回事

装完后发现宝塔挂了

装完后发现宝塔挂了，之前安装好的建站环境都显示未安装，环境是debian7+宝塔

想问一下service的文件是那里编译

请问一下，service的运行文件是在那里编译出来的？

请问如何完全卸载服务端和客户端

请问如何完全卸载服务端和客户端
想重新安装一下

你好大大，请教下为何我的安装后

本机不显示实时流量等信息，其他的客户端倒是没问题
不知道怎样解决多谢

逻辑优化：客户端部署

on 32 bits node
$ wget http://IP:15944/static/client_x86 -O client
on 64 bits node
$ wget http://IP:15944/static/client_x86_64 -O client

可优化为：wget http://IP:15944/static/client_$(uname -m) -O stathub_client && chmod +x stathub_client

磁盘空间占用显示不对

应该显示成21%

应该显示成94.8%

系统提示我升级~问下怎么升级？

客户端也要再来一遍吗？

引入workspace改善文件组织结构

目录结构：

bin/
    server_x86
    server_x86_64
    server_start.sh
    server_stop.sh
    client_x86
    client_x86_64
src/
    server/
        .....
    client/
        .....

构建过程：

GOOS=linux GOARCH=386   go build -o bin/server_x86    server
GOOS=linux GOARCH=amd64 go build -o bin/server_x86_64 server
GOOS=linux GOARCH=386   go build -o bin/client_x86    client
GOOS=linux GOARCH=amd64 go build -o bin/client_x86_64 client

考虑支持 Windows 吗

rc.local的两个问题

你好，我用的Ubuntu，反馈以下两个问题。

1、有些版本（如oracle的ubuntu 18镜像）没有rc.local文件，也没有调用rc.local的/etc/init.d/rc.local文件，安装时有如下错误：

2019-12-06 07:46:49 (7.37 MB/s) - ‘stathub.x86_64.tar.gz’ saved [2744821/2744821]

2、16.04和18.03两个版本的rc.local默认最后一行是exit 0，stathub的启动命令默认被放在了此行后面，造成了重启后服务不会自动启动。

I check the /var/stathub/data and the log file is empty.

其实我是想在Windows下使用Client

Can I run both server and client on my single VPS ?

click password again and faile

我使用密码登录进去之后，再点击右上角的password，进入登录界面，这时输入密码likexian就不能登录。
console errror是 Failed to parse SourceMap: https://IP:15944/static/bootstrap.css.map

增加 robots.txt 屏蔽搜索引擎收录

使用 ./service stop 进程并没有被杀死

使用了 ./service stop 进程并没有被杀死，pid 文件倒是被删掉了
看了一下 service 源码

stop() {
    echo "stopping"
    if [ -f $PID ]; then
        kill `cat $PID`
        rm -rf $PID
        echo "ok"
    fi
}

建议使用 kill -9 强制杀死
kill 会发送 SIGTERM 信号给程序，然后看程序怎么做了
kill -9 会发送 SIGKILL 信号给程序，强杀

能有arm的吗？

因为是树莓派的client~~~

优化建议：服务端和客户端程序体积压缩

解决问题的终端输出记录，显示stop未能终止进程：

在此之前运行了过一次`service stop`了，输出结果除了stopping还有前面的一行，不过输出被覆盖掉看不到了。

然后页面恢复正常了。
