如何使用 Conky 监控我的 mythtv 后端？

Question 1

只是对 mythtv-status 选项做一个快速评论，您可以设置主机选项，在/etc/default/mythtv-status这种情况下，如果 mythtv-status 升级或重新安装，它会被记住。

您还可以设置其他选项，例如打开彩色输出并向输出添加其他信息。

Question 2

来自论坛帖子（内容和语法已编辑）：

我最近发现了这一点，因为我需要其他东西，但我认为检查远程和本地前端的状态可能会很好。

http://www.mythtv.org/wiki/Telnet_socket

我编写了一个脚本，用于在 conky 中显示本地和远程前端的状态，我想与你分享。我刚刚开始学习编写脚本，这是我第一次尝试使用变量，我主要只是将一些可以从 shell 中输入的内容放入其中，而无需变量或错误更正，因此我为此学习了一些准备工作。

有关如何使用的说明位于文件的注释中，并且此链接应该让您了解 mythtv telnet 以及如何启用它。

考虑到为了在 conky 中启用几行代码而不得不编写的大量代码，我认为这非常微妙。无论如何，这对我来说很有趣，我希望人们尝试一下，并告诉我它进展如何，如果您需要任何帮助，我很乐意帮助您设置它。

Question 3

这是关于在任何 ubuntu 机器上使用 conky 查看后端录制信息的操作方法。这可以通过在使用 conky 的 ubuntu 机器上安装 mythtv-status 来实现。我对 mythtv-status 做了一些修改。

/home/username/.mythtv/config.xml将你的 mythbuntu 盒子复制到你的本地 ubuntu 桌面/home/username/.mythtv/config.xml
编辑 config.xml 文件以反映后端的 IP 地址
```
gedit ~/.mythtv/config.xml
```
编辑此行。将 localhost 更改为后端的 IP 地址。在我的例子中
```
<DBHostName>localhost</DBHostName>
```
变成：
```
<DBHostName>192.168.15.3</DBHostName>
```
将 config.xml 链接到/root/.mythtv/config.xml
```
sudo mkdir /root/.mythtv
sudo ln -s ~/.mythtv/config.xml /root/.mythtv/config.xml
```
这是为了修复 mythtv 状态中的 perl api 警告。
安装 mythtv-status

sudo apt-get 更新 sudo apt-get 安装 mythtv-status
编辑 mythtv-status 来反映我的更改。
```
sudo gedit /usr/bin/mythtv-status
```
大约 21 行。将 localhost 更改为后端的 ip 地址
```
my $host = "localhost";
```
在我的例子中，它变为。
```
my $host = "192.168.15.3";
```

编辑.conkyrc 文件以添加输出。

gedit ~.conkyrc

在顶部附近添加：

text_buffer_size 1024

在底部添加

${color #0077ff} ${execi 300 perl /usr/bin/mythtv-status KISP}

更改颜色以对应您当前的 .conkyrc 配置。

运行conky进行测试。
