It is used to measure how a gauge metric (like available filesystem bytes) behaves over time rather than at a single instant.  \nFor example:  \navg_over_time(node_filesystem_avail_bytes[1h])  \nThis query returns the average amount of available filesystem space observed across all samples within the last hour for each time series.  \nBy contrast:  \navg() performs aggregation across diferent series at a single point, not over time.  \nsum() and sum_over_time() compute totals rather than averages.  \nThus, only avg_over_time() provides the correct temporal average.  \nReference:  \nExtracted and verified fromPrometheus documentation-Range Vector Functions, avg_over_time() Definition, and Working with Gauge Metrics Over Time sections.  \nNEW QUESTION \\# 52  \nGiven the metric prometheus_tsdb_lowest_timestamp_seconds, how do you know in which month the lowest timestamp ofyour Prometheus TSDBbelongs?  \n A. prometheus_tsdb_lowest_timestamp_seconds % month  \n B. (time() -prometheus_tsdb_lowest_timestamp_seconds) / 86400  \n C. month(prometheus_tsdb_lowest_timestamp_seconds)  \n D. format_date(prometheus_tsdb_lowest_timestamp_seconds,\"%M\")  \nAnswer: B  \nExplanation:  \nThe metric prometheus_tsdb_lowest_timestamp_seconds provides the oldest stored sample timestamp in Prometheus's local TSDB (in Unix epoch seconds). To determine the age or approximate date ofthis timestamp, you compare it with the current time (using time() in PromQL).  \nThe expression:  \n(time() -prometheus_tsdb_lowest_timestamp_seconds) / 86400  \nconverts the di ference between the current time and the oldest timestamp from seconds into days (1 day = 86,400 seconds). This gives the number of days since the earliest sample was stored, allowing you to infer the time range and approximate month ma","cbCaigs8hES296bb","https://ap.wps.com/l/cbCaigs8hES296bb","pdf",91916,1,"English","en",105,"# Exam Questions and Explanations\n## PromQL sample questions (Q51–Q56)\n## Concepts: temporal averaging and comparisons\n## Concepts: TSDB timestamp interpretation\n## Concepts: Alertmanager inhibition rules","[{\"question\":\"What PromQL function returns an average over the last hour for filesystem free bytes?\",\"answer\":\"Use avg_over_time(node_filesystem_avail_bytes[1h]).
