スクリプトインプリメンテーションcloudstackのリソースとステータス情報をhtmlレポートで表示する
8127 ワード
環境に複数のcloudstackが複数のvdcを構築し、スクリプトでリソース情報を取得し、レポートとしてメールに送信したい
以下は簡略化版の考え方です.
1、構成ファイルの構築
これらのcloudstackの情報はxmlファイルで格納されます.以下のようにします.
2、リモート実行コードモジュールの実現
3、cloudstack情報モジュールの作成
4、フォーマット出力html
html_end = ""
html_str = html_start + " "
for i in tr_list:
html_str = html_str + " %s" % i
html_str = html_str + " "
for item in source_list:
html_str += " "
for attr in tr_list:
if attr not in item:
html_str += " "
else:
html_str += " %s" % item[attr]
html_str += " "
return html_str+"
