Add functionality to limit RAM usage (Windows)

Windows Sisense currently has no way for us as administrators to control how much ram is being used by elasticubes. From looking at the community site, it appears that linux has a way to do this through data groups, but when consulting with support, I have been told to increase our resources, simplify our models, etc.

 

The big problems that we have observed at my company is that

1. Sisense seems to take up the resources it is given - when ram is increased, usage percentage stays at the same level

2. If something does go wrong and resources begin to get consumed, there are no guard rails in place to stop whatever incident is happening from taking down the whole server

This second case has happened only a few times in the years we have had Sisense, but I don't like that I have no way to be proactive about these issues.

    jamnikej ,

    Before migrating to Linux we also experienced this struggle / issue. What eventually helped us and minimize/prevent downtime is Process Lasso Server Edition (https://bitsum.com/server/). You can configure this to restart services when they reach a certain threshold regarding CPU/Mem. For us this reduced the amount of 503-errors or very slow user experience. 

    It is not a real solution, it is more a band-aid, but untill there is a fix (or untill you perhaps migrate to Linux) . I can recommend this tool

    Hi jamnikej,

    Hello .

    Thank you for your feedback! I would like to get this Idea over to the product team, but first I would like to get more information and head off any roadblocks to implementation.

    How would you like to see Sisense implement these "guard rails"? Are you looking for things you already use third-party server monitoring apps for? Can you provide some examples?

    Thank you for working with me to get this Idea fleshed out so it can be evaluated and scoped for effort.

    Have a great day!

    Hi,

    We are really looking for a way to control how much data can be cached by Sisense - when I look at this article - Data Groups In-depth - it looks like similar functionality is set up for linux. The article points out that complex aggregations and formulas can lead to increased caching of ram as dashboards are being accessed - this is what we are experiencing on our windows instance. 

    I am happy with a tool like data groups being implemented on windows that would allow us to put a cap on how much ram a set of queries can take up, and setting up a time to auto-stop sources that are no longer being used. I am really looking for the data groups tool to be available for windows rather than a completely new tool be invented.
