Adding same metric with different label values

[Ankit Kumar]

Hi Guys,

I was trying to add the same metric with different label values using the following querry:

metric_total{label1="label1", label2="label2"} + ignoring(label2) metric_total(label2="label3")

However, I get "No Data". Not sure what is the issue, can someone help?

With such a low level of details I am afraid it will be difficult to help.

Can you provide a sample of actual metrics?

You can also try https://promlens.com/ which could help you understand what is going on.

Hi Julien,

Thanks for letting me know about promlens. Got to know the issue. Im so lame!!

To summarise:

my metric was defined as 

metric(label1,label2,label3,label4) value

When label2 changed label4 was also changing 

Hence, metric_total{label1="label1", label2="label2"} + ignoring(label2) metric_total(label2="label3") was not able to find a match (since both label2 and label4 changed but only label2 was ignored)

Fixed it by adding label4 to the ingoring list

metric_total{label1="label1", label2="label2"} + ignoring(label2,label4) metric_total(label2="label3") 

Regards

Ankit
