Influxdb and grafane retriving less number of rows than inserted

$

What are you trying to achieve?

I inserted 997 metrics into InfluxDB and want to visualize and count them correctly in Grafana.


How are you trying to achieve it?

  • Inserted 997 data points into the testUTC_1krows bucket in InfluxDB.
  • Queried using Flux in Grafana:
from(bucket: "testUTC_1krows")
|> range(start: 2024-02-07T12:55:00Z, stop: 2024-02-07T15:49:10Z)
|> count()

What happened?

  • The query only returns 505 metrics instead of 997.

What did you expect to happen?

  • The count query in Grafana and influx should return 997 metrics instead of 505.
  • No data loss or filtering should occur.

Configuration Details

  • InfluxDB Bucket: testUTC_1krows
  • Timezone Used: UTC
  • Grafana Timezone: (Browser Time / UTC)
  • Server Timezone: Confirmed as Etc/UTC (+0000)
  • Command output:
date -u
Sun Mar 16 12:02:40 UTC 2025
timedatectl
Time zone: Etc/UTC (UTC, +0000)

Errors in Grafana UI or Logs?

  • No direct errors, but incorrect count() results.
  • Possible incorrect handling of time ranges or missing data points.

Did you follow any online instructions?

Yes, I followed:

  • InfluxDB count query documentation
  • Grafana Time-Series Data Debugging

Note : it is stored csv and not continous data. any help would be appriciated, also want to know if influxdb and grafana works for such data ?or just incoming data
