Using Grafana 6.3 and Graphite to display metrics generated by collectd.
My servers contain various applications, so collectd collects some common metrics like cpu, memory and some app-specific metrics.
I want to create a dashboard for just one of these apps, so don’t want to include servers without the app.
Graphite folder structure looks like this (much simplified):
I want a panel for each instance of metric1, which is easy enough using a query variable with value “collectd..app1.”, but when I use that variable in the repeat panel field and panel title, I get two panels, each with the title metric1.
Ideally what I want is each panel to have the server name and metric name as its title, but I can’t see how to extract the server name.
I tried creating a server query variable “collectd.*” and using that to template the rows, but then I get a row for all servers, including server2, even though it doesn’t have app1.
Is there a way to ensure that the server variable only returns values if the app1 sub-folder folder exists?
Any suggestions please?
