Node red - counter timer

[Andy Haig]

HI 

I am having a brain fade, so if someone could point me in the right direction here, I would be grateful

I want to count the number of messages i receive on a given flow in a given time - and then (When the timer expires) 

- emit a single message with the total

- reset the time and total 

All help and commentary gratefully received; abuse less so, but acknowledged as karmic punishment for my hangover

Cheers

Andy

One way would be 2 flows:

1st: use inject node to trigger every x seconds/minutes/whatever, read flow variable, output, reset flow variable

2nd: for each msg recvd, add 1 to a flow variable, continue processing

It looks like this might do it, though not used it myself

I use https://flows.nodered.org/node/node-red-contrib-counter for similar task

It counts incoming messages and also allows special messages to reset counter or report current state (for this I set "Default Step"=0 and enrich every message that has to be counted with msg.increment=1)
