in the new version, rate() and histogram_quantile() functions, producing the same result as their PromQL counterparts, have been added. Other new additions to complement this functionality are the bucket_rate_foreach() differences and similarities between PromQL and Zabbix Prometheus preprocessing query language. PromQL instant vector selector Zabbix Prometheus preprocessing Differences 354 PromQL instant vector selector Zabbix Supported foreach functions: bucket_rate_foreach Functionally corresponds to ’histogram_quantile’ of PromQL. Returns -1 if values of the last ’Infinity’ bucket (”+inf”) are equal to 0. Examples: => his-
