Hi, I’m just going through the SNMP Extension 2.0 and have been adding interfaces/disks to the entity screen by following the examples in here: > **[blogPostMaterial/topology-extraction-diskstation at master ·...](https://github.com/wolfgangB33r/blogPostMaterial/tree/master/topology-extraction-diskstation)** > > master/topology-extraction-diskstation I had a look at the schemas but it doesn’t provide enough details on how to further use things like entity list cards or what can be done on screens etc. It’s hard to work off the few examples available.  Is there a cache of examples or more detailed documentation on what can be done for extension 2.0? ---

[@jun\_phoon](https://community.dynatrace.com/user/38132), In the beginning, it seems really link a big task. I hope you’ve also had a look at the documentation at [About Extensions — Dynatrace Docs](https://www.dynatrace.com/support/help/extend-dynatrace/extensions20/extensions-concepts) There are a lot more pages on the menu on the left side. Afterwards, please share your more concrete difficulties, and the Community will try to help :dynaspin: ---

Hi [@jun\_phoon](https://community.dynatrace.com/user/38132), we are preparing a dedicated documentation page for configuring unified analysis pages for domain-specific entities. In fact, we will be using the example you referenced and we will be explaining concepts like entities list card. Please stay tuned. The doc page will be live soon. Thanks, Daniela ---

Hello [@jun\_phoon](https://community.dynatrace.com/user/38132) We have now documentation for configuration of unified analysis pages available here: [Extend Dynatrace with domain-specific web UI — Dynatrace Docs](https://www.dynatrace.com/support/help/extend-dynatrace/extend-ui) Please take a look and let us know if there are further use cases that you’d need us to describe there. Thanks! Daniela ---

Hi [@daniela\_rabiser](https://community.dynatrace.com/user/38764) Thanks for the further documentation it’s much appreciated - I will have a look at the video when I can as well. There is a “screen:” related question i posted below regarding list filters and “showGlobalFilter”  - I can’t seem to get it to work with the custom entities i created - it would be good to have some sense of description of how the filters work for screens.

Updating and improving the documentation would be much appreciated. The documentation which has been present for the last 12 months or so, is lacking any good examples of much of the functionality, there is little to no explanation on how the different things work, and add to that the logging our output you get from the extension 2.0 is also missing or severely lacking. ---

Hi [@tarjei](https://community.dynatrace.com/user/12960), thanks for reaching out. Are you referring to the documentation of UI page configurations part of extensions 2.0, or would you suggest adding documentation on a different aspect of extensions 2.0? What topics would you like to see addressed in the documentation? Thanks! ---

Hi [@daniela\_rabiser](https://community.dynatrace.com/user/38764) ! I am talking about the Yaml stuff. Just at the moment I have been on the support chat since yesterday, to get some examples / explanations on how to use the filtering mechanisms. > **[Extension YAML file](https://docs.dynatrace.com/docs/ingest-from/extensions/develop-your-extensions/extension-yaml)** > > Learn how to create an extension YAML file using the Extensions framework. ---

Hi [@jun\_phoon](https://community.dynatrace.com/user/38132) Until we have official documentation ready, I hope this quick post can get you further with your extension screens development: [https://community.dynatrace.com/t5/Dynatrace-tips/Extension-2-0-Screens-How-to-add-filtering/m-p/189329#M430](https://community.dynatrace.com/post/189329#M430) Best regards, Radu ---

Hi [@tarjei](https://community.dynatrace.com/user/12960) While the documentation explains the core concept, I have added some additional examples in this quick post [https://community.dynatrace.com/t5/Dynatrace-tips/Extensions-2-0-How-to-use-dimension-filters/m-p/189340#M431](https://community.dynatrace.com/post/189340#M431) I hope this gets you further with your extension development.

Hi Radu, Just regarding the dimension filter in extensions.  My collegue found that variable filters in the extensions, where you can define them in the extension config - has a 500 character limit. Is this documented somewhere? Can the limit be increased?
