Raise a problem when license consumption is close to limit

deni — Mon, 29 Sep 2025 06:41:29 GMT

Hi,

We are using a Dynatrace Managed environment and would like to automatically raise a problem when license consumption (for example, DDUs) is close to being exhausted.

I checked the available metrics but couldn’t find anything like ddu.used or hostunits.used. I did see some metrics such as billing.ddu.log.total, but for DDUs there are also metrics and traces that need to be considered in the calculation, not just logs.

Is there a way to monitor the overall license consumption across all DDU categories?
Can we set up alerting or problem generation for approaching license limits in Dynatrace Managed?
If there are no direct metrics, what would be the recommended approach to achieve this?

Any advice or best practices would be greatly appreciated.

Regards, Deni

Hi,

Managed is more limited about that.

For DDU categories, you can try this dashboard.

I do not know any way to alert automatically in Managed about that. I would say review before dashboard to checking trend, and compare to limit your license has.-

Best regards

For these purposes we developed an Extension 2.0 which creates metrics per Dynatrace environment and you can then alert using Metric events. It scrapes the Cluster API and writes metrics.

@Julius_LomanThanks for the reply!

If I understand correct you suggest to create a custom extension which calls API to collect the license information and the sent a custom event via v2/events/ingest?

I searched in the swagger but can't find API to get licenses - I see only v1/config/clusterid and v1/clusterversion nothing more in v1, v2 and config APIs connected to cluster or license.

In managed you should know from your license the amount of DDUs you have (i.e. a fixed number)

What you can do is have a metric event to alert on this, but keep in mind this will be per environment.

((builtin:billing.ddu.metrics.total:splitBy():sum:default(0):fold(sum)) + (builtin:billing.ddu.log.total:splitBy():sum:default(0):fold(sum)) + (builtin:billing.ddu.serverless.total:splitBy():sum:default(0):fold(sum)) + (builtin:billing.ddu.events.total:splitBy():sum:default(0):fold(sum)) + (builtin:billing.ddu.traces.total:splitBy():sum:default(0):fold(sum)))

That will give you the total amount used.

Let's say your total available is 1M, so put as a static threshold in the metric event with something like 800k.

With an extension, script or synthetic-test you could extract this information for the whole cluster from this API https://docs.dynatrace.com/managed/shortlink/api-cluster-get-license-consumption

Also maybe something to have a look at are DDU pools, where you can assign a specific env a limit of DDUs allowed to be consumed. https://docs.dynatrace.com/docs/shortlink/davis-data-units#ddu-pools

@deni - https://docs.dynatrace.com/managed/shortlink/api-cluster-environments-list-existing
This includes consumption data (Classic licensing per environment).

Mark's answer is also valid if you need it for a single environment. We had a requirement to alert on DDU consumption for two environments together, which is not possible with metrics just from a single environment.

Hi,

I'm pasting the code which I'm using:

with requests.get(f"{DT_CLUSTER_URL}/api/cluster/v2/license/consumption", headers=headers, stream=True, verify=VERIFY_SSL) as response: ... with inner_zip.open(json_filename) as json_file: with io.TextIOWrapper(json_file, encoding="utf-8") as text_file: data = json.load(text_file) env_entries = data.get("environmentBillingEntries", []) for env in env_entries: # Sum DDUs for pool in env.get("davisDataUnits", []): total_ddus += safe_float(pool.get("total", 0)) # Count hosts host_usages = env.get("hostUsages", []) total_hostunits += len(host_usages) # Count DEMs (based on agent usages per host) for host in host_usages: total_dems += len(host.get("agentUsages", [])) print("Aggregated License Consumption (from license start until now):") print(f" Total DDUs used: {total_ddus:.2f}") print(f" Total DEMs used: {total_dems}") print(f" Total Host Units used: {total_hostunits}")

I saw that there are two environments in this Managed Dynatrace Cluster. The information on the /cmc shows aggregating result for the current consumed/available licenses and that's why I'm also aggregating the results. The problem is that the results which I get completely differs from these shown in the /cmc:

Aggregated License Consumption (from license start until now): Total DDUs used: 93747.71 Total DEMs used: 4428 Total Host Units used: 4424

but in the /cmc it is:

Host Units: 15/15 DEM: 2.07k/10k DDU: 599.51k/900k

Can you help me with that?

Regards, Deni

Since Dynatrace Managed version 1.326, new Cluster v2 APIs are available for retrieving host, Davis data, and DEM unit information. For details, see https://docs.dynatrace.com/managed/shortlink/release-notes-managed-sprint-326#track-your-cluster-license-usage-via-api

In an upcoming release, we will also provide cluster billing metrics that allow you to define alerts in the self-monitoring environment when your license units are running low. Stay tuned!

We will also provide a dashboard for tracking the cluster license usage. See this preview:

Hi,

@_Alexander_ Thank you! Nice improvement!

Do you know if that dashboard is going to be deployed automatically or do we need to import it manually?

Best regards

It will be deployed automatically to the Local Self-Monitoring environment
