Charting the sum of two Prometheus data source values in Grafana
I am trying to create a chart in Grafana with Prometheus data source which includes a series indicating the total size of the young gen memory used on a java 8 jvm. Below is the formula I have used to sum the values together:
(jvm_memory_pool_bytes_usedjob="jmx",instance=~"my-jboss-server:10191",pool="PS Eden Space"
+
jvm_memory_pool_bytes_usedjob="jmx",instance=~"my-jboss-server:10191",pool="PS Survivor Space")
I am able to chart the individual values for PS Survivor Space and PS Eden Space but as soon as I try to add them together, there is no data returned.
Below is some sample data which is returned:
jvm_memory_pool_bytes_usedpool="PS Eden Space", 5.83346368E8
jvm_memory_pool_bytes_usedpool="PS Survivor Space", 8.5090432E7

You can use the sum() function. It would probably look something like
sum(jvm_memory_pool_bytes_usedPS Survivor Space", [other labels])

That does not work - I can see it is returning values in the query inspector but there is no line in the chart for these values.

There appears to be some kinda a bug where the chart does not work. Tried the exact same query and it worked.
