Hi, did you find a solution?

I’m looking for the same thing.

Solved this by adding a dummy field for each request I log, where the content is simply the value 1. Then in grafana, I can use the sum aggregator and an inline script that allow me to calculate a rate given a time interval like 5m, where the script is simply value / 605*.

Thank you, meanwhile i was able to solve it in another way.

My syslog-ng sends every 10m a message log to graylog with its stats, i then do some processing in graylog to create the fields d_graylog_processed, d_graylog_dropped, etc…

for example d_graylog_processed containers the number of messages that were processed by syslog-ng regarding the graylog destination on the last 10m.

I was able to make it work with sum and derivative.

I just added some overrides to hide the sum field and rename the derivative one.
