I am currently setting up grafana alerts. How do I customize my message template so my alert email shows The ip address of the server, the state of the server and the node/instance?
Thank you.
I figured it out once, then recently I updated my grafana instance that wiped my work and I had to figure it out again. It was tough the first time.
You can use the labels that are made available through prometheus in your summary and description sections in your alerts by using the syntax:
{{$labels.instance}}
{{$labels.value}}
https://prometheus.io/docs/prometheus/latest/configuration/template_examples/
The only catch is that you have to use Math expression in the last condition in your alert rule for the labels to be available in the Summary section of the alert.
For example, in our personal alerts we will use something like:
Machine {{$labels.instance}} is not reporting status via win-exporter.
The machine could be offline or the service could be stopped.

I am using Grafana to set up email alerts. I have all my panels on my dashbboard created, and just turned the alerts on. However, I am now getting the following error. Alert execution exceeded the timeout. This is sending emails for all the servers on that dashboard to everyone associated with the email alert. Why is this happening? Is there too many servers on one data source? Should I change the data source from 1 to multiple?
The question is old, but still someone comes here looking for answer.
It happens when the data source you are using to generate the charts response very slowly ~ > 30s. In that case graph throws the error execution time out.
I would like to reference predefined variables, or those defined in templating section of dashboard, to customize alert message, but nothing I tried seems to work. Is it supported at all?
Considering the fact that nobody answered, most probably this is not supported yet in Grafana. However, in my particular case, as the values of variables are known and can be fixed at deploy time (I basically just wanted to notify from which environment comes notification, test or prod), the issue can be solved by using ansible variables in inventory files and fix the message in grafana, at deploy time. But in other cases, this is not sufficient and implementation within Grafana is required.
We are using grafana to visualize the influx data. There are multiple dashboard created in. Because of some technical issue there may not be new data in Influx to display in the dashboard because of some downtime.
Is there a possibilities that I can add a panel in all the dashboard with an alert message of the downtime. So that dash board users don't have to go anywhere and notified about the downtime there itself.
Thanks
I think that it's not possible to configure a pop up like you want with grafana.
Find another notification channel (e-mail,discord,slack,...).
If you really want a pop up, this wont be configured in Grafana but in Javascript. To do that, you'll have to custom your Grafana page.For that, i can't help ou.
I am trying to implement alerting using grafana and prometheus.
As Grafana does not allow template variables in metrics to be used in alerting, I am currently forced to hardcode the IP's if I want to collect the memory metrics.
But that's not a solution that can long last, as the nodes in my setup can terminate and get recreated as auto-scaling is enabled.
Is there any better alternative than hardcoding each instance IP in the metric and still enable alerting on memory usage of each node?
Any help will be really appreciated.
Yeah, that's why we've given up on using alerts in Grafana and decided to use Alertmanager. For that you'll need to create alert rules and add them to PrometheusRule resource on the cluster and configure alertmanager itself.
if you can figure out how to add your required info into labels, you can reference labels in your alert message using the template like so:
{{$labels.instance}}
Anything that's reported in the instance as a label should be available, however, it's only available if the alert ends in a math expression. It isn't available for alerts that use a classic expression.
I'm evaluating Jopr 2.3.1 to monitor a JBoss 4.2.3 Application Server.
Jopr, based on the better known RHQ Project from Redhat, supports to send email notifications triggered by so called alerts. Alerts can be defined to react to certain changes of system parameter such as metrics (e.g. 'Active Thread Count', 'JVM Free Memory') or the availability (e.g. goes UP, goes DOWN) changes.
I'm now wondering if it's also possible to send a for instance weekly status report by email?
Just to make sure: This email notification is to be send periodically, indipendent of the regular alter notification, rather problems occured or not.
Many thanks in advance - every hint is appreciated

RHQ 3 (anything Jopr related is old and outdated) has server side plugins.
They can be alert notification senders that let you e.g. connect to a trouble ticket system for alert notifications.
They can also be more generic and can be triggered periodically via an "internal cron". The latter may be what you want for report sending. In fact, Mazz has already written an example plugin generating a report on file system - you would only need to change the "write to disk" to "send email".
