I was able to install Grafana and Influxdb in a docker on my Synology NAS.
Also able to create graphs in Grafana from the persisted items and able to show an Image on my sitemap. So far so good.
What I am looking for is dynamic graphs (so updating the data frequently and showing it on my sitemap). With the option to take the embedded graph version from Grafana I am stuck.
After reading multiple hours I still don’t know how to get it working.
The Image element on the sitemap takes a “refresh” argument. That is how frequently the image will be reloaded in milliseconds.
Rich I do have a refresh in the statement but it is not refreshing at all.
My statement is
Image refresh=60000 url="http://10.10.10.10:3003/render/d-solo/S9FCyA6Wk/openhab?orgId=1&from=1588575377704&to=1588596977704&panelId=2&width=1000&height=500&tz=Europe%2FAmsterdam"
It shows the below Image on the sitemap but it is never reloading.
Below is the actual graph from Grafana.
I just took the pictures a minute ago.
Maybe it is just a refresh issue.
Your render URL is using fixed to and from timestamps. You need to use something like
from=now-1h&to=now
Look in the Grafana docs for all the right ways to define it. But if I recall correctly:
- s = seconds
- m = minutes
- h = hours
- d = days
- w = weeks
- M = months
- y = years
