parse error: missing unit character in duration

[derekakelly]

Hello, About half of the sections are coming up like this.

I'm using Ubuntu 21.04, with Prometheus version 2.22.0+ds-1, and prometheus-node-exporter version 1.1.0+ds-2. Both installed with apt. I have Grafana version 6.7.4, installed with snap.

I had this dashboard working on another install, but it's fighting me a bit here.

Hello @derekakelly , I had the same error when I used Grafana 6.7.2, I resolved the parse issue by upgrading grafana to version 7.5.7.

the problem for grafana6 is the use of $__rate_interval, only availlable in grafana 7+

As a workaround, you can edit the json source and replace :

• rate -> irate
• $__rate_interval -> 5m

10 second in notepad++ :

open the json file use the replace function with regex : search: rate((.*)\$__rate_interval replace by: irate(${1}5m

copy the json to grafana and enjoy this great dashboard (thank you @rfrail3 👍 )

@bjolivot : $__rate_interval -> $__interval will do the job, if you want to keep the interval configurable.

Any way how to fix it in new Grafana?

any fix for grafana/grafana-oss:9.2.6?

From what I've found online, these are the wrong Variables. Go into settings/variables and they should all be with a green checkmark, and the missing ones will show up if you click the link at the bottom.

What I did was that I found a partially working dashboard, added the necessary panels from other dashboards to it and copied variables from them.

Some variables are repeated, such as job or node. Then I rename the variable to job2 and node2 in the dashboard settings and later in editing the panel, replace $job with $job 2 in the code and everything works.

Here a sample code: node_memory_MemFree_bytes{job="$job2",instance=~"$node2:$port",job=~"$job2"}

Original code: node_memory_MemFree_bytes{job="$job",instance=~"$node:$port",job=~"$job"}

Node-exporter for server stats, cAdvisor for docker stats, Prometheus for storing data, Grafana to visualize it.
