Unable to filter by node in Grafana

[hdbjeff]

Repro:
Open the Explore tab: https://[stack].grafana.net/explore
Load the Harper datasource

Do the following
Select the duration metric
Add Condition: attribute node comparator equals value [valid node name] type auto
0 series returned

However if you
Select the duration metric
Add Condition: attribute path comparator equals value [valid path name] type auto
series data is returned

@hdbjeff Thanks for reporting! This will have to be handled specially due to some optimizations in how we encode node hostnames in the analytics data. As a result we will have to filter these in JS code rather than in query conditions. That means the equals comparator will be easy to implement, and one or two others probably also not a big deal, but supporting all of them would be a bigger effort. Is supporting just equals OK to start?

It is important to support all equally, otherwise inconsistent behaviors will emerge.
