调用阿里云api获取阿里云数据同步服务（DTS）并且作图发送邮件的整个流程

前言在https://rorschachchan.github.io/2018/02/24/阿里云获取DTS服务延迟的脚本/ 文章里已经写过，领导现在要求“每天查看阿里云dts同步的延迟情况和同步速率情况”，并且在https://rorschachchan.github.io/2018/02/27/使用matplotlib画图的一个脚本/ 里面也放了一个使用python matplotlib画图的demo，这篇文章的目的就是把整个过程实现，并且把dts图形以每日邮件的形式发送给领导的效果！实现需求的思路本次需求有四个动作，分别是获取一天以内的DTS延迟和同步速率、将获取到的DTS值做成PNG图像、将生成的PNG图像上传到阿里云云存储OSS 、把图片展示到邮件里并发送给相关领导。由于第一步获取一天以内的DTS延迟和同步速率需要将这个脚本每小时执行一次，执行24次，才可以执行生成png图像这一步，所以后三个其实可以写成一个大脚本。不过在本文为了表述的清楚，就把各自不同用途写成了不同的脚本。获取阿里云DTS延迟和同步速率的脚本这个脚本这里再拿出来晒一遍： #!/usr/bin/env python #coding=utf-8 #这个脚本是用来获取dts延迟数字的 from aliyunsdkcore import client from

SSIS vs. DTS performance

问题 Seems crazy to be doing this at this late date, but... I am rebuilding some ETL infrastructure with a Rocket Software UniVerse source and an SQL destination. The old destination platform was SQL 2000 on Windows Server 2003, the new platform is SQL 2012 on Windows Server 2012. In both cases, an ODBC driver is used to connect to the source. Everything seems to work fine on the new platform, but the execution time for a package is exponentially slower. For example, one table with roughly 1.3

Can the ffmpeg av libs return an accurate PTS?

阅读更多关于 Can the ffmpeg av libs return an accurate PTS?

问题 I'm working with an mpeg stream that uses a IBBP... GOP sequence. The (DTS,PTS) values returned for the first 4 AVPackets are as follows: I=(0,3) B=(1,1) B=(2,2) P=(3,6) The PTS on the I frame looks like it is legit, but then the PTS on the B frames cannot be right, since the B frames shouldn't be displayed before the I frame as their PTS values indicate. I've also tried decoding the packets and using the pts value in the resulting AVFrame, put that PTS is always set to zero. Is there any way

问题 I get an "Index was outside the bounds of the array." error when I do the following. 1) I launch the Import and Export Data Wizard (32 bit). 2) Data source: .Net Framework Data Provider for Odbc. 3) I provide a connection string and DSN for a 32 bit Progress OpenEdge 10.2A ODBC driver that I've set up. 4) I set up a flat file destination. 5) When I click "Next" I get the following error: TITLE: SQL Server Import and Export Wizard Column information for the source and the destination data

How do you copy a MS SQL 2000 database programmatically using C#?

阅读更多关于 How do you copy a MS SQL 2000 database programmatically using C#?

问题 I need to copy several tables from one DB to another in SQL Server 2000, using C# (VS 2005). The call needs to be parameterized - I need to be able to pass in the name of the database to which I am going to be copying these tables. I could use DTS with parameters, but I can't find any sample code that does this from C#. Alternatively, I could just use drop table TableName select * into TableName from SourceDB..TableName and then reconstruct the indexes etc - but that is really kludgy. Any

MySQL to SQL Server transferring data

问题 I need to convert data that already exists in a MySQL database, to a SQL Server database. The caveat here is that the old database was poorly designed, but the new one is in a proper 3N form. Does any one have any tips on how to go about doing this? I have SSMS 2005. Can I use this to connect to the MySQL DB and create a DTS? Or do I need to use SSIS? Do I need to script out the MySQL DB and alter every statement to "insert" into the SQL Server DB? Has anyone gone through this before? Please

DTS/SSIS vs. Informatica Power Center

问题 I'm sure that this is a pretty vague question that is difficult to answer but I would be grateful for any general thoughts on the subject. Let me give you a quick background. A decade ago, we used to write data loads reading input flat files from legacy applications and load them into our Datamart. Originally, our load programs were written in VB6 and cursored through the flat file and for each record, performed this general process: 1) Look up the record. If found, update it 2) else insert

问题 I have a very old project implemented in (classic) ASP and SQL Server 2000. Because of quality concerns, I've been considering the possibility of implementing some form of automated quality testing. Though, the web pages are ASP the project is really 85% SQL Server stored procedure, functions, views and DTS. (Lots of dependency on DTS) A lot of code generation occurs from SQL Server. In regards to the DTS, we are hoping to possibly upgrade the database to SQL Server 2005 -- so If unit testing

SSIS XMLSource only seeing null values in XML variable

问题 I have a Data Flow task with an XMLSource that references an XML Variable. The DataFlow task does recognize that there are x number of rows in the variable, but it only sees null values in every row: The xml variable value: <?xml version="1.0" encoding="utf-8"?> <words> <word>butter</word> <word>crispy</word> </words> I used this source to generate the XSD within the XMLSource Editor - here is the auto-generated XSD: <?xml version="1.0"?> <xs:schema attributeFormDefault="unqualified"
