Is it possible to change the value only for a single graph in a dashboard?
Like this pseudo promql ($vertical is taken from global dropdown):
if $vertical=='fido2' then $vertical='multi-tenant' endif
sum(kafka_consumergroup_lag_sum{topic=~".+$vertical.+", \
consumergroup=~".+$testenv", consumergroup=~".+events.+"})
I found a workaround, but any no data will trigger the same:
sum(kafka_consumergroup_lag_sum{topic=~".+$vertical.+",\
consumergroup=~".+$testenv", consumergroup=~".+events.+"})
OR
sum(kafka_consumergroup_lag_sum{topic=~".+multi-tenant.+",\
consumergroup=~".+$testenv", consumergroup=~".+events.+"})

Is it possible to transform the alias by in Grafana to map data? The measurement I have already includes the tag interface_name which translates to things like 'Bundle-Ether 1'. Then I have a variable query that pulls the interface description using that interface_name.
In the dashboard I have the following panel
Which gives a legend of
Is it possible to map the tag_interface_name to the interface_description? So that instead of Bundle-Ether1 on the legend I get the corresponding description
Bundle-Ether1 = 'Description'
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 am trying to make a detailed dashboard in grafana that opens on click. I do it by passing a variable to the dashboard debending on the clicked facility. When the dashboard opens it needs to display value using the passed url variable inst. I just cannot seem to get it working. Here is an example of my dashboard link.
How can i use the variable inst?
I will add gogibogi4's correct answer. The Grafana documentation is lacking on this.
In your drill-down dashboard, add a constant variable. To be retrieved in Grafana, you need the prefix var- then the name of the variable in the query string. Let's assume the variable is "region." The URL coming into the drilldown dashboard should look similar to the following:
/drilldowndashboard/?var-region=NorthWest
Drilldown Dashboard Settings:
In the drilldown dashboard settings, create a variable. The Name in this example is "region" Make the type Constant. Under Hide, you can just leave that unselected. Under Constant options, you can write the word "blank" The preview of values will just show the word "blank" but go ahead and save it as it will be replaced in the query.
Query:
You can refer to the variable using [[region]] in your data query.
Parent Dashboard:
The parent dashboard merely needs to refer to the drilldown dashboard with var-region as a query parameter.
I figured out the solution on my own. The variable that i wanted to pass was var-inst, the trick to use it is to create a custom template variable named inst and give it a dummy value. After that is done i can use the passed value by using $inst. Note that in order for the variable to be passed i had to go back to my primary dashboard and then i had to click my link again. After that the value got passed and is working perfectly.
just referred above answer by gogibogi4 and it worked for me but when I tried to see variable information then I saw I have selected constant as a type but automatically it got converted into datasource and type is selected grafana. when I try to select them manually it didn't worked. this is some kind of bug of grafana I guess.
I am building Grafana (4.1.1) graphs with a Prometheus (1.1.2) backend, and am trying to use Templates to select/deselect certain sub-sets of metrics on a dashboard. I have a template variable called "$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'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
