如何使用 Conky 監控 mythtv 後端？

我想使用Conky 來監控mythtv 後端，我該如何設定？

答案1

只是對 mytv-status 選項進行快速評論，您可以設定主機選項，在/etc/default/mythtv-status這種情況下，如果 mytv-status 升級或重新安裝，它將被記住。

您也可以設定其他選項，例如開啟顏色輸出並向輸出添加其他資訊。

答案2

來自論壇貼文（內容與語法編輯）：

我最近發現了這一點，因為我需要其他東西，但我認為檢查遠端和本地前端的狀態可能會很好。

我編寫了一個在 conky 中顯示本地和遠端前端狀態的腳本，我想與您分享。我剛剛學習腳本編寫，這是我第一次嘗試變量，我主要只是將一些東西放入其中，我可以從 shell 中輸入類型，沒有變量或糾錯，所以我學會了一些準備工作。

有關如何使用的說明位於文件的註釋中這個連結應該讓您了解 mytv telnet 以及如何啟用它。

#Version 0.4 "       " added more events to output in human friendly terms changes it so only one instance of nc is used to prevent hammering of ports
#Version 0.5 17/04/09 add some fixes to playback status and added a check status in the even the frontend not running but the host is up

考慮到我必須寫多少才能在 conky 中啟用幾行，我認為這是相當微妙的。不管怎樣，這對我來說很有趣，我希望人們嘗試一下，如果您需要任何幫助，請告訴我它是如何回复的，如果您在設置時遇到任何問題，我很樂意為您提供幫助。

答案3

這是關於在任何 ubuntu 機器上使用 conky 查看後端錄製資訊的操作方法。這是透過在使用 conky 的 ubuntu 機器上安裝 mythtv-status 來實現的。我稍微修改了mythtv-status。

  1. /home/username/.mythtv/config.xml將您的 mythbuntu 盒子複製到本機 ubuntu 桌面/home/username/.mythtv/config.xml

  2. 編輯 config.xml 檔案以反映後端的 IP 位址

    gedit ~/.mythtv/config.xml

    編輯這一行。將 localhost 變更為您後端的 IP 位址。就我而言

    <DBHostName>localhost</DBHostName>

    變成：

    <DBHostName>192.168.15.3</DBHostName>

  3. 將 config.xml 連結到/root/.mythtv/config.xml

    sudo mkdir /root/.mythtv
sudo ln -s ~/.mythtv/config.xml /root/.mythtv/config.xml

    這是為了修復 mytv 狀態下的 perl api 警告。

  4. 安裝 mythv-status

    sudo apt-get 更新 sudo apt-get 安裝 mytv-status

  5. 編輯 mytv-status 以反映我的更改。

    sudo gedit /usr/bin/mythtv-status

    在第 21 行左右，將 localhost 變更為後端的 ip 位址

    my $host = "localhost";

    在我的例子中它變成了。

    my $host = "192.168.15.3";

  6. 編輯 .conkyrc 檔案以新增輸出。

    gedit ~.conkyrc

    在頂部附近新增：

    text_buffer_size 1024

    在底部添加

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

變更顏色以對應您目前的 .conkyrc 配置。

執行conky進行測試。
