Hi All - new to Grafana. I am using a prebuilt dashboard that up until recently was displaying data correctly at any time interval. However, now it is not displaying CPU or traffic data for any time interval under 8 hours. No changes have been made to prometheus or grafana and as you can see certain dashbaords populate while CPU and network traffic do not. any help is apprecaited… thank you
Hi @ericphipps,
Can you share query that’s behind panels that aren’t showing data? Also, can you share link or dashboard ID which you used to import dashboard in grafana?
So, if you set time range for longer than 8 hours you get data?
Thank you Idrascic - below are your answers and attached is a screen shot showing 8 hours. Probably unrelated but the data goes missing around the 7:30-7:45 mark
Query: sum by (instance)(rate(node_cpu_seconds_total{mode=“system”,instance=“$node”,job=“$job”}[$__rate_interval])) * 100
Query: CPU Busy
(((count(count(node_cpu_seconds_total{instance=“$node”,job=“$job”}) by (cpu))) - avg(sum by (mode)(rate(node_cpu_seconds_total{mode=‘idle’,instance=“$node”,job=“$job”}[$__rate_interval])))) * 100) / count(count(node_cpu_seconds_total{instance=“$node”,job=“$job”}) by (cpu))
