Not sure if this is actually the right place to start this topic, but I couldn´t find any more suitable. Since I´m having fatal problems with Grafana rendering crashing openhab, after upgrading openhab from 2.3 to 2.4, Markus @mstormi suggest to look at the EXTRA_JAVA_OPTS in the /etc/default/openh…

[image] Kim_Andersen: Webview crashed openhab as well… webview with no PhantomJS present? that’s the main point. there should be no PhantomJS on your machine at all. [image] Kim_Andersen: ´m not quite sure which URL to use for Webview. I just used the original URL when I tried webview fi…

I found I got less ram issues out of a PI when I left off the Xms parameter. Since I no longer use a PI I never looked into it in enough depth to be 100% sure why this was, perhaps it was FRAGMENTATION caused by the use of a GC which does not compact after cleaning. I value my time higher then the …

[image] rlkoshak: is only required to be installed manually from 5.2.0. Previous versions of Grafana ship with the library as part of it. Yes.. I misunderstood the 5.2.0 update of Grafana. I thought PhantomJS was implented at that time, and previous version didn´t. [image] rlkoshak: if y…

[image] matt1: I value my time higher then the cost to upgrade so I see it as a waste of time trying to make a system that is clearly near its maximum to work as it may just stop working the next update or when I add a few extra components to my smart home… Agree.. I have given up trying to s…

[image] Kim_Andersen: Agree… I have given up trying to solve this. Give it one more try and add another swapfile or grow the existing one (see my post how to, but don’t set the swappiness value). At least in theory, the memory that’s useable to processes is not RAM but the virtual memory whi…

I´ll take a look at your post. Thanks Markus.

[image] Kim_Andersen: The Grafana version that comes with openhabian-config is 5.3.4. This version requires PhantomJS to be able to render charts, right? Wrong. It only requires that library to render static images of your charts. And as of that version of Grafana, that feature is no longer s…

[image] rlkoshak: One can ignore this and restore the ability to render static images of charts by manually restoring PhantomJS. But that puts your Grafana in an unsupported and unrecommended configuration. But static images are not the only way to put charts on your sitemap and the other ways …

[image] Kim_Andersen: I know of no other way to put charts on a sitemap except for using webview, as you suggested. Exactly. The original tutorial presents two ways to put charts on your sitemap using a Webview. Image is no longer supported by Grafana. [image] Kim_Andersen: If PhantomJS…

[image] mstormi: Give it one more try and add another swapfile or grow the existing one (see my post how to, but don’t set the swappiness value). Markus, should I just deleted the value, or comment out the command CONF_SWAPSIZE=100 ?? I assume it requires an reboot after change? EDIT: I gav…
