error :*"tsdb.HandleRequest() error invalid value type" in Grafana alert config

[bckim]

hi, all

I have one question about grafana alert system.

[IMG2=JSON]{“data-align”:“none”,“data-size”:“full”,“src”:“https://www.percona.com/forums/filedata/fetch?filedataid=922&type=thumb”}[/IMG2][IMG2=JSON]{“data-align”:“none”,“data-size”:“full”,“src”:“https://www.percona.com/forums/image/gif;base64,R0lGODlhAQABAPABAP///wAAACH5BAEKAAAALAAAAAABAAEAAAICRAEAOw==”}[/IMG2]​
the graph is fine,

metric : node_load1{instance=“big5db”}

but when I use “alert config” using this graph, there is some error.

error : “tsdb.HandleRequest() error invalid value type”

could I know why this error ouccured?

thanks.

this issue can be resolved in grafana 4.6.2 version.

so we need to upgrade grafana in pmm docker.
