Hi everyone, is there a way to setup a log to monitor past data from an input? I'm still rather confused on how to set one after reading through some forums.
What I have in mind was to set the log to store up to 10 data or to display top 10 latest information for people to read.
Thanks in advance
Do you want that data logged in Node-RED or in the browser? Both are possible.
Ehhh I wanted to log the past few things registered through Node-RED and have the history of it displayed on the dashboard. Although, I've found a way to work on it, but the ui doesn't seem nice since I'm using the ui_table to display the log. Any other suggestion on which node should I use?
Here is a scrolling message table on the dashboard as well as writing to a log file on disk
One of the other members on here gave me the basic code for this a LONG time ago (sorry can't remember who) - i have not looked at it in more than a year or so - but should do what you want

Hi Craig, is there a reason why the text's white?
Nope not at all - probably because i use the dark theme?
Craig
Ah, makes sense. Think that solved my issue on making the log, thank you so much!!
No worries - i note there are a couple of trivial errors thrown in the Function node in the javascript code - you could probably clean it up and get rid of them with a little bit of playing.
