End-of-life announcements

Team,

Please make sure you pay attention to this page: End-of-life announcements.

https://docs.dynatrace.com/docs/whats-new/technology/end-of-life-announcements#scheduled-eol-for-unsupported-oneagent-versions

Reminder: Keep your Dynatrace agents updated! EOL versions will eventually be blocked from the platform. It’s a necessary move to phase out legacy versions, so please check your support status today.

End of Support (EoS)

Last date on which Dynatrace provides bug fixes or security updates.
After EoS, the component keeps running, but maintenance stops and support is best-effort only. Features will no longer be maintained, and no critical fixes will be deployed.
Ongoing operation, and associated risk, becomes the customer’s responsibility.

End of Life (EoL)

Latest date when Dynatrace disables, removes, or blocks the component, ending its useful operation.
Upgrade paths remain open so you can migrate and continue getting full value from Dynatrace.
Support tickets related to the component are no longer accepted.

Scheduled EOL for unsupported OneAgent versions

If you are running any of the OneAgent versions listed below, upgrade to a supported version before the EOL date to ensure uninterrupted monitoring.

OneAgent versions Standard EoS 1 EoL

1.141 and earlier	2018	Aug 1, 2025
1.215 and earlier	April 29, 2022	Oct 1, 2025
1.241 and earlier	June 8, 2023	Jan 1, 2026
1.299 and earlier	Sep 30, 2025	Sep 1, 2026

Here are a couple of DQL queries that may help:

fetch dt.entity.host, from:-1h
| fieldsAdd installerVersion,paasVendorType,lifetime
| sort installerVersion asc
| filter isNotNull(installerVersion)

| summarize count = count(), by:{installerVersion}

fetch dt.entity.host, from:-1h
| fieldsAdd installerVersion,paasVendorType,lifetime
| sort installerVersion asc
| filter isNotNull(installerVersion)

Good luck and keep updating.

Good to know, this changed recently. We still have customers running hosts with OA 1.269 (RHEL 5, Windows 2008). I already knew about EOL 1.241 and below, but 1.299 is a new one for me.

I only noticed this today! One thing is EOS, another is EOL! Is Dynatrace shooting itself in the foot? The amount of systems that will not be supported is astonishing!

Hi @AntonioSousa ,

Isn't it standard OnAgent support less than 12 months?

@MartinKulov ,
There are two different things:

End of Support (EoS)
End of Life (EoL)

EoL means it won't work any more: Latest date when Dynatrace disables, removes, or blocks the component, ending its useful operation.

I got that, thanks.

Just wondering what is the EoL per Dynatrace policy? Any ideas?

Two years seems like a good enough timeframe.

You have environments that span longer not being updated?

@MartinKulov ,

Yes, my clients have LOT's of systems that won't be supported by 1.301.

And that's not even the biggest point: Six months ago, agents with more than 7 years would still work. In six months, Dynatrace will effectively be reducing EOL to 2 years. From more than 7 years, it's going down to 2 years!
