I am building Grafana (4.1.1) graphs with a Prometheus (1.1.2) backend, and am trying to use Templates to select/deselect certain sub-sets of metrics on a dashboard. I have a template variable called "$POP" which describes my city locations, and a template variable called "$Resolver" which describes the type of resolver I am using ("unbound" or "pdns" are the possible string results.)
I have these two metrics like this that work quite well currently selecting on the various values in $POP:
irate(dnsdist_recursor_main_servers_unbound_drops{env="prod",loc=~"$POP"}[1m]) > 0
irate(dnsdist_recursor_main_servers_pdns_drops{env="prod",loc=~"$POP"}[1m]) > 0
Putting aside for the moment that instead of labels the selection criteria are embedded in the metric name (I know it's not ideal but this is just an example of larger problem sets so please do not suggest how I can use labels) I would like the following results:
When (~"$Resolver" == "unbound") I would like to show the first metric (dnsdist_recursor_main_servers_unbound_drops) and when (~"$Resolver" == "pdns") I would like to show the second one (dnsdist_recursor_main_servers_pdns_drops) and when both are selected I'd like to show both metric set data. Basically, I hope to have an on/off visibility trigger for a metric that is keyed to my $Resolver template value.
How do I create a boolean such that the metric is shown or not shown based on the setting of the string value in the templated setting of $Resolver? The trick here is that the selection criteria is in the metric name, not a label, which is really stumping me. I tried "bool" modifiers but was never able to get anything to work on string equality tests. I'm sure it's just a syntax issue but examples are thin on the ground.
What you can take advantage of here is that there's no uniqueness restriction on label selectors, so you can do {resolver="$resolver",resolver="unbound"}

I have Grafana dashboards with “Stat” components and I try to change the display names.
I’ve found only one working way: add a field override using regexp. All works, but I can’t use groups in regexp. I want to do something like:
My_own_metric_(.+_.+) -> $1
I’ve tried a lot of different way to write it: $1, \1, ${“\1”},..
But I was only able to change it on static text.
I’m using Grafana-8.3.3-Ubuntu version.
Maybe someone knows a solution?
Apparently it's not possible to use groups in field override.
What you need to do is add an "operation" in the query itself:
+ Operations > Functions > Label replace
and set the legend:
Options > Legend > Custom > {{yourlabel}}.
So, an example for a straightforward mqtt exporter query,
changing the displayed label
from $SYS/broker/clients/maximum
to maximum:
I would like to create a dynamic dashboard of my cluster nodes. this dashboard will be composed of multiple single state panels. each one shows the status and name of a node
So this what I have done:
create a template variable list_of_vm = label_values(up{job="node_exporter"},instance) by checking multi-value combo
the result of this is something like ip1:port, ip2:port, ... , ip7:port
create un single state panel with repeat panel set to list_of_vm. And in metrics I set up{instance="$list_of_vm",job="node_exporter"}
After checking all instances in the template variable, the panels are correctly duplicated, but their value is wrong because in metric the query is evaluated as : up{instance="$list_of_vm",job="node_exporter"}
when list_of_vm = "ip1:port+ip2:port+..+ip7:port"
And I am expecting to have ip1:port for the first panel, ip2:port for the second one...
Do you have any idea to fix this problem
I'm currently building a component that has TouchUI configuration properties separated with three tabs (Standard, CASL, GDPR). Each tab has the same set of options available and my current config names are similar to the following:
./standardMarketingText
./standardThirdpartyText
./gdprMarketingText
./gdprThirdpartyText
./caslMarketingText
./caslThirdpartyText
(There are several other options for standard,gdpr,casl but I left them out for brevity)
While this works, I'm hoping to instead store the values in the JCR as a JSON node per category. For example:
casl = {"marketingText"="m test", "thirdpartyText"="tp test"}
gdpr = {"marketingText"="gdpr m test", "thirdpartyText"="gdpr tp test"}
This way I can load all "casl" (or others) options at once when I need them (there isn't a case where I would only load one "casl" option)
I have attempted using granite/ui/components/foundation/form/multifield however, it asks to "Add field". I only want one set of each, and not provide the ability to add another set of properties under each tab. Is there a way to accomplish this without overriding the multifield resourceType?
There are multiple ways to achieve what you are looking at, I would look at the reusability as there are similar named properties for different categories (in your case tabs). To group them you could do that at node level by correctly defining the name property for each tab.
For above provided values, you could do something like -
./standard/marketingText
./standard/thirdpartyText
./gdpr/marketingText
./gdpr/thirdpartyText
./casl/marketingText
./casl/thirdpartyText
Your each tab stores the properties in named node (standard, gdpr, casl). In addition you could have a single SlingModel/WCMUsePojo that can adapt to these nodes to provide the Pojo with accessor to property values.
As far as getting JSON is concerned, your SlingModel or WCMUsePojo can provide a method to return JSON based string for the values.
I have two Shape Data rows for a Shape's ShapeSheet:
Shape Data Label Prompt Type Format Value Invisible
Prop.Type "Type" "" 4 "Alpha;Beta;Gamma;Delta;Epsilon;Zeta;Eta;Theta;Iota;Kappa" INDEX(4,Prop.Type.Format) False
Prop.Abbrev "Abbrev" No Formula 4 "A;B;G;D;E;Z;E;T;I;K" INDEX(4,Prop.Abbrev.Format) True
The way I intent to use this is to have the user select the Type, say Epsilon, and then have the Abbrev automatically switch to the corresponding value in the Prop.Abbrev.Format.
Note: the values used here are placeholders for the actual values for my application, which are not shown here so they don't distract from the real answer I need, how to keep the selections in sync when the first one is chosen or changed.
Thanks for any help you can give!
I don't have Visio on this machine, so I am unable to copy and paste a working solution. The approach gets a little complicated, but extremely flexible.
Save your lists in the User section, rather than Prop - this then becomes underlying data for use in properties. If you are using a master stencil then this also helps with managing the fields.
You can now store an index in your data as well - this index points to the appropriate values in your arrays. You can use Actions and side menus to set the index which, when referenced properly, means you can have the full name and/or abbreviation in the side menu and the ShapeSheet does all the work underneath.
The functions you want to look at are:
Index (e.g. INDEX(1,User.Type) will return "Beta". (0-based)
Lookup (e.g. LOOKUP("D", User.Abbrev) will return "3". (0-based)
GetAtRef
SetAtRef
SetAtRefExpr
SetF
I had a similar business problem which relied on setting a background colour based on the value of shape data. Your final solution could end up including formulas like this: =SETF(GetRef(Prop.Type),"GUARD(INDEX(LOOKUP(Prop.X,Prop.X.Format),User.Type))").

I'm making a Grafana dashboard and want a panel that reports the latest version of our app. The version is reported as a label in the app_version (say) metric like so:
app_version_updated{instance="eu99",version="1.5.0-abcdefg"}
I've tried a number of Prometheus queries to extract the version label as a string from the latest member of this time series, to no effect.
For example, the query
count(app_version_updated) by (version)
returns a {version="1.5.0-abcdefg"} element with a value of 1. When put in a Grafana dashboard in a single value panel, this doesn't display the version string but instead the count value (1).
How can I construct a Prometheus query that returns the version string?
My answer tries to elaborate on Carl's answer. I assume that the GUI layout may have changed a little since 2016, so it took me while to find the "name" option.
Assuming you have a metric as follows:
# HELP db2_prometheus_adapter_info Information on the state of the DB2-Prometheus-Adapter
# TYPE db2_prometheus_adapter_info gauge
db2_prometheus_adapter_info{app_state="UP") 1.0
and you would like to show the value of the label app_state.
Follow these steps:
Create a "SingleStat" visualization.
Go to the "Queries" tab:
Enter the name (here db2_prometheus_adapter_info) of the metric.
Enter the label name as the legend using the {{[LABEL]}} notation (here {{app_state}}).
Activate the "instant" option.
Go to the "Visualization" tab:
Choose the value "Name" under "Value - Stat".
Note on the "Instant" setting: This setting switches from a range query to a simplified query only returning the most recent value of the metric (also see What does the "instant" checkbox in grafana graphs based on prometheus do?). If not activated, the panel will show an error as soon as there is more than one distinct value for the label in the history of the metric. For a "normal" metric you would remedy this by choosing "current" in the "Value - Stat" option. But doing so here prevents your label value to be shown.
We recently added support for displaying the serie name as a value in the single stat panel (https://github.com/grafana/grafana/issues/4740). So you have to run our nightly build until we release 4.0.
Just make sure the query returns one serie and you can use the "name" value in the dropdown under Options -> big value.Then you can format the string using the legend formater. Ex {{job}} would return "node" as a serie name.
I hope this answers your question.
While most of #marcus-rickert's answer is still valid in Grafana 7, there is some change.
The 'Stat' 'Name' field seems to be gone, instead in the 'Field' panel, you can set the 'Display name' to the label you want to show.
This worked for me.
label_values(my_metric{type= "xxx", another_label="xxx"},target_label)
With Stat visualization in Grafana 8+, you can set the legend to the intended label name and then change the Stat Styles -> Text Mode to Name
Prometheus doesn't have any functions that return strings, what you're looking for is for a Grafana singlestat to be able to display a label value - which it unfortunately doesn't support yet.
https://github.com/grafana/grafana/issues/5094 tracks this.
Another update on very latest kube-prometheus-stack using grafana 8.0.3. I still faced this issue, for me in a Bar gauge I still had this issue in scenarios where it only returned 1 value, but with 2+ values the Legend field works OK.
My solution:
Go to Edit Panel, find Display Name, type
${__field.labels.insertYourLegendValueHere}
I wanted to get all the various values of a label from Prometheus to put into a variable in Grafana. I used this simple query to populate my varialbe Drop-Down list:
label_values(myLabelName)
This returned the expected "value01", "value02" etc
