CSV Datasource with URL Connector http://username:password@...

Hi,

I'm trying to setup a CSV datasource which uses a URL Connector.
Purpose is to get live monitoring status information from a Nagios/Check_MK server which does provide the info as csv.

The access to this URL has to be protected with username and password.

A datasource of type "Relational Database " provides two fields for username and password including the security mechanism to not send back the password to browser.
A datasource of type "CSV List" with "URL connector" does not provide such username and password fields.

I've also tried to include the username:password into URL as "http://username:password@IPofNagiosServer/check_mk/view.py/....", but always receive a 401 Authentication required.

Error message:
"
Error
The report could not be executed: java.lang.IllegalStateException: java.lang.IllegalStateException: java.io.IOException: Server returned HTTP response code: 401 for URL: http://username:password@IPofNagiosServer/check_mk/view.py?view_name=servicegroup&servicegroup=PROD&output_format=csv_export
"

On Nagios/Check_MK apache the username+password seem to not arrive. Apache httpd access.log:

172.0.0.2 - - [19/Jun/2015:17:06:09 +0200] "GET /check_mk/view.py?view_name=servicegroup&servicegroup=PROD&output_format=csv_export HTTP/1.1" 401 401 "-" "Java/1.7.0_79"


My first assumption:
Username + password in URL are not supported by java.net.URL / java.net.URLConnection and would need to be provided via HTTP header / connection property "Authentication: Basic <encoded username:password>"


I do not see this as a bug, but as an potential improvement/feature to support passwords for URL Connectors and to protect them in a similar way as you do already for Database connections.

Re: CSV Datasource with URL Connector http://username:password@...

Remark:
my current workaround is to load the csv via curl triggered by cron into local filesystem and use for the datasource URL file:///pathtocsvfile

Re: CSV Datasource with URL Connector http://username:password@...

Hi,

you are right. For HTTP Authentication one indeed needs to do some extra work on the java side which is why this is currently not working. I've added a feature request ticket for this. In the mean time, if you are not happy with the curl based solution you could also do some hack in RS: you could point the URL to a ReportServer script (scriptAccess) and have the script go and get the CSV.

Cheers

Re: CSV Datasource with URL Connector http://username:password@...

Couple questions about CSV datasources via URL:
1) Has support for http://username:password@aaa.bbb.ccc.ddd/URL been added?
2) Lets say we get a CSV datasource via http set up so that it does not need a username and password, how do you go about testing it?

Re: CSV Datasource with URL Connector http://username:password@...

To answer my question above, it does appear that http://username:password@aaa.bbb.ccc.ddd/URL works.

Re: CSV Datasource with URL Connector http://username:password@...

Hi,

what is the optimal syntax for putting files via curl to the local RS fileserver?

What is the correct Url of a fileserver folder?

Thanks,

Christoph

Re: CSV Datasource with URL Connector http://username:password@...

Hi Christoph,

did you check the SFTP feature? https://reportserver.net/en/guides/admi … TP-Server/
If you install sftp, you can put files easily via SFTP.

Regards,
Eduardo
