Hi all, me again.
I have an influxDB temperature source:
When I enable query A and/or B and/or C then the temperature graph shows spikes:
What could cause this?
Thanks for any help!
Can anyone offer any help? Thanks!
Looks quite odd - and possibly a bug. I guess the value of the line chart is “stacked” along with the bar charts, even though it’s (I assume) on a separate y-axis? Maybe try adding an override to the line chart to explicitly disable stacking, and see if that helps?
Otherwise check the Grafana GitHub Issues list. I feel like I’ve seen behavior like this reported there before (and maybe already fixed in more recent versions)
I had a similar issue where a panel that I copied and changed to stacked was all spiked. Data was created every 5m, but the telegraf collector was set to check for data every 60s. I am using inputs.directory_monitor.
I changed the agent interval from “60s” to “5m” in telegraf.conf file and restarted telegraf.
After that, the graph on the stacked panel started to smooth out the new data.
Hope that helps.
