tm1s.cfg parameters cheatsheet

The number of parameters in the tm1s.cfg has been steadily rising as more features have been made available over the years in TM1. So, a cheatsheet summarising all these parameters can help as an overview of the different settings that a TM1 server can be configured with.

This cheatsheet is now available in the following formats:

  • csv so you can build your own variations of the cheatsheet
  • tm1s.cfg including all parameters, only the required parameters are uncommented, every parameter is set to its known default value (as of 2023-02-14 and according to the IBM online documentation). There should not be a need to explicitly define a parameter when you just want to stick to the default value. However, be cautious that IBM may change default values and that could lead to issues when upgrading versions.
  • md markdown to save in your personal knowledge management repository full of markdown files to ripgrep through fzf.vim
  • pdf for an allegedly pretty overview (coming soon)
  • html below or here on its own that you can "Save as" to use as a local copy.

The cheatsheet is generated with python scripts (coming soon) responsible for the conversion of the csv file to a pandas dataframe and then exported to different formats. The csv file currently holds the following fields:

  1. parameter: name of the parameter
  2. optional: indicates if the parameter is either required or optional.
  3. restart: indicates if the parameter is either dynamic or static 🔄, in the later case, it requires a service restart when its value has been modified
  4. url: URL address of the official IBM Planning Analytics documentation for that parameter
  5. default: default value of that parameter when it is not explicitly declared
  6. type: type of that parameter (bool, int, float, str, time). This will be useful for scripts checking tm1s.cfg validity
  7. context: arbitrary categorisation for the context of the parameter e.g. it can be Network related, Rules related, etc..
  8. dependency: that may hold the name of another parameter that the current parameter may rely on to operate
  9. description: short description about what the parameter does

The categorisation is completely arbitrary, most parameters could fit in several categories, so I just picked one that seemed most appropriate. This is a limitation and probably something to look into for the design of future versions of that csv file.

And finally, the tm1s.cfg parameters cheatsheet in html.

Note that there is a drop down menu at the top of the Context column. This allows you to show only parameters that relate to a specific aspect of your TM1 server. If you are on mobile, you probably need to rotate your screen for a wide display in order to display all 5 columns.
