Hi All,
Just upgraded to OH2.2 yesterday, which to be fair went pretty smoothly, but I have ran into the following issue when trying to view performance charts from Grafana/Influxdb server.
The charts appear fine when OH 2.2 has just been started but after a short period I get blank images, via web page or IOS app, and I get the below error in the OH logs.
2017-12-22 09:00:46.770 [WARN ] [.internal.proxy.BlockingProxyServlet] - Proxy servlet failed to stream content due to a timeout
2017-12-22 09:00:48.013 [WARN ] [.internal.proxy.BlockingProxyServlet] - Proxy servlet failed to stream content due to a timeout
2017-12-22 09:04:50.385 [WARN ] [.internal.proxy.BlockingProxyServlet] - Proxy servlet failed to stream content due to a timeout
I’m using the following in my sitemap which was working fine in the previous OH 2.1 build.
Image item=System_Temperature_CPU
url="http://192.168.1.176:3000/render/dashboard-solo/db/openhab?orgId=1&refresh=5m&panelId=2&from=now-1d&to=now&width=1000&height=320&tz=UTC%2B00%3A00"
refresh=60000
Grafana/Influxdb run on a separate Pi3 as it has been for several months.
Running on:
Pi3
Raspbian GNU/Linux 8.0 (jessie)
OH installation/upgrades via APT
openhab-cli info
Version: 2.2.0 (Build)
User: openhab (Active Process 10735)
