Is there a way we can get data(like interface utilization data of routers) from Cacti server remotely?
I did come accross some answers which said using rrdtool export options,but i was wondering if there was a way to do it without touching the rrd's?I would be using a linux server to remotely access this data.
There is no RESTAPI for CACTI, however you can pull the details from the database tables

We have a multi-tenant, single db application where some customers have expressed the desire to get direct access to their own data.
I have been suggested looking into Azure Data Sync to achieve a setup where each of the customers get their own Azure SQL instance to which we setup a one-way synchronization of their data from the master database.
I managed to find some documentation on this, but one I got around to try it out in a lab setup, it looks like the ability to filter rows in the sync job has been removed in a later iteration of the Azure Data Sync service.
Am I wrong or is that feature really gone? If so, what would be your suggestions to achieve something similar on Azure?
You cannot filter rows using Azure SQL Data Sync. However, you can build a custom solution based on Sync Framework as explained here.
Usually a Tableau dashboard operates on "static" data that are "attached" to the published dashboard. I wonder if it is possible to make Tableau able to read data on-the-fly (when a user interacts with it). By that I mean that the data, that should be visualized, are taken from a data base that can by "dynamic". It means, for example, that the data shown by Tableau today and yesterday should not be the same because content of the database might change. Alternatively, we might try to retrieve data from an API. For example Tableau sends a request to a HTTP server and gets a data table in form of JSON and than visualizes it. Is Tableau able to do that?
Yes, Tableau can connect to live data sources such as any number of database technologies. No, it cannot send HTTP requests for JSON directly. It does a have web data connection feature if you or someone has built that web service. Here are some tips on when to use Live connections versus taking an Extract. http://mindmajix.com/use-direct-connection-data-extract-tableau/
I am trying to connect tableau desktop to Hadoop Hive connection. I want to change the default hive engine to TEZ . How can i change this parameter through tableau desktop?
One thing which I have figured it out is, you can use :
initial SQL
option to set default engine to TEZ. However problem with this is, it only gets fired when firing first tableau query, for subsequent queries again engine related changes are reverted back.I am in research on this with Tableau, and will post once I hear anything concrete.
I am working with a client that has data in an MSSQL database. I only have read access to a remote ODBC connection and cannot modify the database in any form.
I'd like to replicate a subset of the data locally in an open-source alternative, syncing once per day or so. This is largely to eliminate reads against the data during peak hours. The local data will be used in a Rails 4 application. Note that syncing only needs to be one-way, as I don't have write access.
How can I best accomplish this?
FreeTDS?
Are there any libraries that will help with the syncing, or can I expect to write all the glue code myself?
I would advise you to create a ruby script that can be scheduled to do the data retrieving.
In order to connect to the MSSQL database, please take a look at this simple project I've created.
Then you only need to code the data you want to retrieve and the way you store it.
I prefer the approach of being decoupled from your rails application, although you can use a scheduler like rufus-scheduler or sidekiq and run it with your application.
Not great at programming so not all that confident of being able to pull data from the Google API.
Basically what I'm trying to do is pull everything from Google Analytics, all data and dump it into a table on a SQL Server (2008 R2). What would be the best way of achieving this?
Would like to automate the process so that it could be scheduled say once a month.
Cheers
There an existing add-on specifically for accessing Google Analytics.
Haven't used it but from what I read seems like it will exactly what you are looking for

There is a specific SSIS DataSource Component for that – https://analyticssource.codeplex.com
It is open source and free.
