# 首先，检查 OpenTSDB 和 TSDB 是否正常运行
curl http://localhost:4242/api/version
curl http://localhost:8242/api/version

# 确认版本是否支持
# OpenTSDB 只保证 2.3.x 是兼容的
# TSDB 只保证 2.4.x 及以上版本是兼容的

# 配置任务
cd /tmp/datax
cp datax/job/job.json opentsdb2tsdb.json

You can download this recording in asciicast v2 format, as a .cast file.

Download

Replay in terminal

You can replay the downloaded recording in your terminal using the asciinema play command:

asciinema play 246856.cast

If you don't have asciinema CLI installed then see installation instructions.

Use with stand-alone player on your website

Download asciinema player from the releases page (you only need .js and .css file), then use it like this:

<!DOCTYPE html>
<html>
<head>
  <link rel="stylesheet" type="text/css" href="asciinema-player.css" />
</head>
<body>
  <div id="player"></div>
  <script src="asciinema-player.min.js"></script>
  <script>
    AsciinemaPlayer.create(
      '/assets/246856.cast',
      document.getElementById('player'),
      { cols: 178, rows: 48 }
    );
  </script>
</body>
</html>

See asciinema player quick-start guide for full usage instructions.

While this site doesn't provide GIF conversion at the moment, you can still do it yourself with the help of asciinema GIF generator utility - agg.

Once you have it installed, generate a GIF with the following command:

agg https://asciinema.org/a/246856 demo.gif

Or, if you already downloaded the recording file:

agg demo.cast demo.gif

Check agg --help for all available options. You can change font family and size, select color theme, adjust speed and more.

See agg manual for full usage instructions.
