Ideally I would also like to be able to show this in color if the time is longer than a certain threshold. Basically the idea is to have a display that shows, for instance, green if a certain backup has been completed in the last 24 hours, and red if it hasn't. Unfortunately, Grafana doesn't understand thresholds in your requested time format older than 24 hours.
Probably table panel will be better - you can use thresholding based on the age metric there.Elysium plot

All of this data-gathering and visualization is great, but in order to truly protect your application and assets, you need a way to alert your teams when something goes wrong.
Prometheus gives us a way to do this by using its modular AlertManager component. Revisiting our diagram from Part 1, we can see that the AlertManager runs alongside of Prometheus, and can integrate with third-party notification tools like PagerDuty:. AlertManager runs standalone alongside Prometheus. It takes care of handling alerts, grouping them, deduplicating them, and routing them to the appropriate services like email, chat, and PagerDuty. It can also silence and inhibit certain alerts during planned events or downtime.
AlertManager rules are conceptualized as routes, giving you the ability to write sophisticated sets of rules to determine where notifications should end up. A default receiver should be configured for every notification, and then additional services can be configured through child routes that match certain conditions, as such:.
In this example, we have instructed AlertManager to route any notifications classified as an outage to PagerDuty.Masterclass: Dashboard Part 3 - Daily time series, Metrics & Power by % threshold bpm panels
Further, if the Alert matches a specific team we send it to a chat solution, and if the Alert matches a particular group we send it to a mailing list. Note that these matches are not exclusive, and an alert can match multiple conditions with multiple destinations. Until then, to set up AlertManager: 1 Download the official distribution and unarchive the bundle.

We first set some global parameters to manage our default behavior, which will be to send an email alert. This part is pretty easy -- we just need to modify our existing Prometheus yaml configuration and let Prometheus know that we have an AlertManager instance ready to go.
We will be statically configuring, but there are discovery mechanisms available as well. The final configuration file will look like:. In this config, then, we are creating an alertmanagers config, and pointing to the instance of AlertManager we have running locally in this demo. This is where we configure our actual thresholds and alerts. Now that we have Prometheus integrated with AlertManager, we will need to configure some rules.
Prometheus gives you a great deal of functionality and flexibility to create your alert conditions which you can read more about here. So in our new rules-amq.Owner financed land eastern ky
In this section, we have a few things going on.Online services should aim to provide a service availability that matches business requirements.
A key part of this process should involve different teams in an organization, for example, from the business development team to the engineering team. To verify how a service complies with these targets, it should be possible to define "thresholds" with measurable "achievements" of these, for example, "Service must be available In the dashboard above, the service went above 0.
A key factor in this result is the time span you choose to measure availability 7 days in above example. For example, if you set a Another trivial "numbers fact" is that adding extra 9s to the SLO has an obvious exponential impact. See the following time fractions for a total 1 year period span:. The above numbers for the allowed time a service can be down may be thought of as an error budgetwhich you consume from events such as the following:. The practical outcome is that any of above will consume error budget from your service, for example, an unexpected outage may deplete it to the point of blocking further maintenance work during that time period.
From the above, it's clear that we must have service metrics to tell us when the service is considered un available. There are several approaches for this:. Let's take a specific example, following the RED method as the metrics we already have available are a better match for this approach : create alerts and dashboards to support a target SLO for the Kubernetes API, via tools commonly used for monitoring purposes: [Prometheus] and [Grafana].
Additionally we'll use [jsonnet] to build our rules and dashboards files, taking advantage of existing library helpers.
Rather than explaining how to signal when your service is out of the thresholds, this article focuses on how to record the time the service has been under this condition, as discussed in [SLOs are about time] slos-are-about-time section. The rest of the article will focus on creating Prometheus rules to capture "time out of SLO", based on thresholds for specific metrics SLIs.
The Kubernetes API exposes several metrics we can use as SLIs, using the Prometheus rate function over a short period here we choose 5min, this number should be a few times your scraping interval :. The formula above discards all metrics labels for example, by http verbcode.
If you want to keep some labels, you'd need to do something similar to the following:. For example, to get the 90th latency quantile in milliseconds: note that the le "less or equal" label is special, as it sets the histogram buckets intervals, see [Prometheus histograms and summaries][promql-histogram] :. PromQL is a very powerful language, although as of Octoberit doesn't yet support nested sub queries for ranges see Prometheus issue for detailsa feature we'll need to be able to compute time ratio for error ratio or latency outside their thresholds.
One very useful outcome of using jsonnet to set our SLO thresholds and code our Prometheus rules, is that we can re-use these to build our Grafana dashboards, without having to copy and paste them, that is, we keep a single source of truth for these. You can read our implementation at dash-kubeapi. Our built Prometheus rules and Grafana dashboard files get produced from the jsonnet sources as the following:.
Since we started this project, many other useful Prometheus rules have been created by the community. If we had to start from scratch again, we'd likely be using the kubernetes-mixin together with jsonnet-bundler.

Like you can see in the following screenshot I am trying to map "no value" to text. What I want to achieve is that in the case of "no value" the text "offline" gets displayed. My guess is that "no value" is not the right parameter to map with, but I have no idea whats the right one. I also tryed NaN which doesnt work to. I would be really happy if someone can point me to the right value here!
Also, for your 2nd mapping, you could use range to text. You could use range to text for both your mappings actually. You might need to save dashboard and refresh it to see changes. It did not update for me without a refresh using an older version though.

There is a long discussion on why alerting with template variable is difficult and maybe not what people actually want:.
I meet this problem too. Then, i can not set alert in child dashboard. Because i use variable in my dashboard. Do you want to create an alert for one server I have a dashboard with a variable, and I want that dashboard to generate an alert.

Proxy access means that the Grafana backend will proxy all requests from the browser, and send them on to the Data Source.
Direct access is still supported because in some cases it may be useful to access a Data Source directly depending on the use case and topology of Grafana, the user, and the Data Source. This way usually faster than pulling data from Zabbix API, especially on the wide time ranges, and reduces amount of data transferred.
