use “fill(previous)” instead of “fill(null)” in histou application while querying influxdb timeseries database

[kaushalshriyan]

Hi Philip Griesbacher,

I am referring to https://support.nagios.com/kb/article/nagios-core-performance-graphs-using-influxdb-nagflux-grafana-histou-802.html I am currently facing issue with the setup. For example, is there a way to run SQL query in InfluxDB for the time period between 17:20 till 18:00 where there is no data? For example http://externalIP:3000/dashboard/script/histou.js?orgId=1&host=dublin-dmz-non-dmz-cszk1.testmoconnect.io&service=Check%20Disk&refresh=30s&fullscreen&edit&panelId=1 I see the below issue.

Is there a way to use “fill(previous)” instead of “fill(null)”, which is the default one in histou application https://github.com/Griesbacher/histou as per the below screenshot?

Please let me know if you need any additional information and I look forward to hearing from you. Thanks in advance.

Best Regards,

Kaushal

Hi, sorry I'm not actively working on Histou. You could create custom simple templates and change the fill behavior, like here: https://github.com/Griesbacher/histou/blob/master/templates/default/ping.simple.example#L54

@Griesbacher I am not sure if I understand it completely. Any examples?

@Griesbacher I will appreciate it if you can help me understand with examples. Thanks in Advance. I working hard to fix this task.

The link I've provided is an example, histou generates JSON which will be used as dashboard by Grafana. Therefore you have to change the histou output to match the Grafana config for your desired Dashboard. The line I've marked is for the filling behavior.
