I am backfilling a month's worth (March 1st to 31st, 2022) of Zabbix trend data (hourly avg values) for a single metric (gauge) with a single label (Hostname). There are 746 datapoints in my OpenMetrics file which I'm converting to TSDB format using the command:

promtool tsdb create-blocks-from openmetrics 300300000360463_history.txt

When I move the data into the Prometheus storage directory the first 15 day and 17 hours of data are removed for some reason. Can anyone tell me why and what I have to do to keep all the data?

Regards,

John

What have you set your Prometheus retention period to? By default it is
