I’m monitoring some data and, although some fields continually change over time, other fields don’t (usually). In fact, they very rarely change; but I want to monitor them nevertheless for if and when they do. Data is being recorded with Telegraf and sent to InfluxDB.
Since several thousand points could have been taken with the same value, is there functionality that de-duplicates this at the InfluxDB level? Or is it possible for me to include a conditional statement when getting the input data in Telegraf? (IE get last value, only store a new point if the new value is different)?
