Saving Custom queries as template variable

Grafana Dashboards
#1
  • What Grafana version and what operating system are you using?
    I am currently using grafana 8.5.4 and mac os 12.4
  • What are you trying to achieve?
    I am trying to save a custom PromQL query as a template variable which i can use in multiple panel dashboards.
    I want to plot a overall health dashboard for my systems. If a value in a panel goes beyond warning threshold but below error threshold then I am plotting it as 1 (or in yellow color) if it goes beyond error threshold then i am plotting as 2(or red color) in another panel.

I have a separate result panel which tracks threshold breach in 3 different panels.

  • How are you trying to achieve it?
    I am planning to use following queries
    warning - (vector(1) and on() (25 <metrics_size >0)) or on() vector(0)
    error - (vector(2) and on() (metrics_size <0)) or on() vector(0)

I have to create 6 different queries (2 for each panel) for result panel.
Can we store this as template query? where i can just change threshold values and metrics name?

If yes how to achieve that. I really appreciate if you suggest any alternate feasible solution for this problem.

this is not super clear to me. can you try and illustrate or screenshot what you are trying to achieve?

I am trying to plot health monitoring metrics using grafana.
I am monitoring multiple panels in grafana. Each of these panels has 2 threshold values
a. warning b. error
In my result health panel I am plotting only if metric value is greater than threshold but less than error then it should mark it as 1 and yellow color.
I am having prometheus as backend db.
so my warning query is
vector(1) and on() (500 < metrics_count{status=~“xyz”} < 1000 ) or on() vector(0)
similarly my error query is
vector(1) and on() (metrics_count{status=~“xyz”} > 1000 ) or on() vector(0)

whenever i use another template variable inside variable and if variable is constant it is giving an error.
Is it possible to do so.
The purpose behind this is I can save query, variable, threshold variables and use it
vector(1) and on() $warning <$AB <$error or on() vector(0)

I will have 2 queries for each panel(warning and error) if i have multiple panels e.g. 10 different panels then i have to write 20 queries in similar way. Adding query as template variable will avoid repetation

Thanks in advance.
