Grafana
Grafana is well-known open platform for beautiful analytics and monitoring.
Data
It’s recommended to exchange data with Grafana either via InfluxDB or via Prometheus.
After database notifier creation, EVA ICS immediately starts sending metrics to the specified database.
Create data source in Grafana.
EVA ICS item metrics automatically appear in Grafana and ready to be selected.
To put current item state on Grafana dashboard (e.g. to gauge), use last value, e.g. for InfluxDB:
SELECT last("value") FROM "sensor:env/temp1"
Controls
Custom UI
You can develop any custom EVA ICS UI and then put it into iframe on Grafana dashboard via Grafana AJAX Plugin.
Install EVA ICS JS Framework
Develop custom web UI and put it into /opt/eva/ui folder
Install AJAX plug-in:
grafana-cli plugins install ryantxu-ajax-panel
systemctl restart grafana-server
Create new visualization in Grafana and embed your custom web UI via iframe.
HMI Block UI
Install HMI Block UI:
cd /opt/eva/ui
mkdir -p apps
cd apps
git clone https://github.com/alttch/eva-hmi-block_ui.git
Follow HMI Block UI documentation and configure it / create interface pages.
Install AJAX plug-in:
grafana-cli plugins install ryantxu-ajax-panel
systemctl restart grafana-server
Create new visualization in Grafana and embed your custom web UI via iframe. See HMI Block UI embedding documentation section for example.
Custom resources
To put custom resource on dashboard (e.g. chart from private local network or camera image), use AJAX plug-in together with SFA PVT.
