I am trying to implement state tracking for a rest collector. How do I reference the state in the collect parameters trying to assign the parameter 'newerThan' an integer with the javascript prevState.lastActivityId == null ? 7369027 : prevState.lastActivityId When I run a preview it just passes url encoded of my javascript, but the expression should set to 7369027

Not Robert's fault. Quirk in the way we handle JS fields that may be plain text To be sure: Start all JS entries with backticks () and use template expressions (${}`) inside to enclose the JS bits. And for text always start with a single or double quote

A preview run won't reference state. You'll need a full run i believe

the get url cribl is sending should just send that integer 7369027 right ?

but it's sending the text of the javascript, that is what I am trying to figure out at least initially.

Looks like you're missing some backticks or related in the config. can you grab a screencap and post here or DM me?

One other detail with the state value references is to make sure you increment the value by 1 second (or 1 millisecond depending on timestamp precision) to avoid duplicates

i was just helping a customer with NinjaOne a few mins ago and happy to help with this one if needed

Hey Randy I was trying to use the lastActivityId to track state, seemed simpler

since the events all have an id field and the API gives you a lastActivityID as part of the top level payload (before you break the events)
Randy Corelli
That's a good callout. If it's an ID vs. timestamp then you don't need to increment it. It's just a detail I see lots of people miss with time based state tracking so I like to mention it

I believe I got the state tracking via the lastactivityid working. I can't seem to crack the pagination, despite having a "pageSize" parameter for the endpoint it returns no other data to help manage pages or point to the next page.
