Custom dashboard based on Kubernetes

[Florin-Marian]

So, I need to create a Dashboard in Dynatrace where I can see the SLA.

Now, let me explain the deployment architecture:

• A deployment represents a component of the application (~ 25 existing at this moment)
• A deployment is present on all/several environments (~ 50 existing at this moment)
• It is considered that the SLA is below 100% when for a certain period of time a deployment remained with 0 active pods on one of the environments.

My dashboard must provide me with information such as: SLA at the application level, SLA at the component level and I can easily see which environment caused the SLA to drop below 100%, seeing exactly which component failed.

I think it is useful to mention the fact that on some deployments we have multiple replicaSets and a formula like the one below sometimes gives erroneous results, having SLA ~ 200% and on some environments only 100%.

(
builtin:kubernetes.pods
:filter(
  in("dt.entity.cloud_application", 
    entitySelector("
      type(cloud_application), 
      entityName.equals(******-api-portal)"
    )
  ),
  and(eq("pod_status","Running")))
:splitBy("dt.entity.cloud_application","dt.entity.cloud_application_namespace")
:sort(value(auto,descending))
)

I mention that I have just started using Dynatrace and I would also appreciate an advanced course on Udemy if you know of any (I only found one for beginners using the "Search" function).

Thank you!

Hi,

you already came up with a nice expression. I tried to simplify it a little:

builtin:kubernetes.pods
  :filter(
    and(
      eq("k8s.workload.name", "frontend"),
      eq("pod_status", "Running")
    )
  )
:splitBy("dt.entity.cloud_application","dt.entity.cloud_application_namespace")
:sort(value(auto,descending))

Does this work better for you? I'm not sure I understand why Replicasets are important here. What I understood: You want to measure if there is at least 1 pod running per workload (deployment, statefulset, ...), no matter which underlying replicaset is controlling it. Please help me understanding 🙂
Out of curiosity: What's the reason you're filtering for "Status=Running" instead of "Phase=Ready"?
best,

Florian
