What does the @mean

Hello, folks,
i have just started to deal with grafana and elastic. in the dokus i see things like @timestamp or @value again and again. Is that a variable that you set somewhere?

can this be used for any elasticsearch database? i connected elastic without metricbeats… and only get to the timestamp when i walk over an object. Means : object.timestamp

@’ doesn’t have any special meaning. It is a historic prefix (“namespacing” - probably to avoid field name conflicts) for some logstash ES fields.

Thank you for your answer!
Otherwise, I would have continued thinking unnecessarily about it :slight_smile:
