[Release] Checkmk innovation release 2.0.0i1

Dear friends of Checkmk,

the new innovation release 2.0.0i1 of Checkmk is ready for download.

We are excited to bring you the first innovation release of Checkmk 2.0. For numerous months our team has been pushing hard to deliver the next full version of Checkmk. In doing so, we have reworked Checkmk’s foundations. With so many significant changes coming finally together, we have decided to
make the version step change to 2.0.

This innovation release is a preview of most features planned for Checkmk 2.0 and gives you the possibility to try these new and interesting features.

With Version 2.0 we will also be introducing a new user interface and user experience. The Innovation Release already contains many aspects of this to gather early feedback.

We will have dedicated channels to gather your feedback on the new user experience:

To get a good grasp of what fundamentals in the user interface have changed, read this forum post containing more details:

We would like to ask all users to try out the new version and help us ensure that Checkmk 2.0 becomes a success.

Please send general feedback, feedback on the new user experience, and bug reports to this dedicated mail address: feedback-2.0 [at] checkmk.com

All mails to this address will be used to improve the 2.0 and are completely free of charge.

This is not a stable release. Please do not use this in productive environments as it is a compromise between stability and new features. It is also only available in the Checkmk Enterprise Editions.

Hallo Zusammen

Habe gerade von 1.6.0p18 auf 2.0.0i1 aktualisiert und bisher alles ausser die Backed Agent funktionier Problemlos, bzw. der Agent ist aktualisiert aber mit folgende Meldung:

WARN - [agent] Version: 2.0.0i2, OS: windows, unexpected agent version 2.0.0i2 (should be 2.0.0i1)

Habt ihr eine Idee……?

PS: Die Adresse feedback-2.0@checkmk.com funktioniert irgendwie nicht, alle Mails werden zurückgeschickt.


Ich würde sagen, das sieht so aus, als wenn der Windows-Agent eine falsche Versionsnummer mitschickt. Diese WARN-Meldung kannst du aber auch abschalten.

Hi Mela,
we have fixed the mail address and it’s forwarding to our ticketing system. Should work now again. Can you resend the feedback please?

Hi @martin.hirschvogel , cool, I send it right now, thanks.

@Dirk, sieht leider nicht so aus, der Agent liefert die richtige version

Abschalte… ja könnte ich, aber will nicht, ich finde sie gut :slight_smile:

Hallo Mela,
hast du diesen Agent per Bakery erhalten?



Hallo @athomaidis, yeap.

@Mela bitte schreib das so in die Email rein.
Die Kollegen schauen sich das an.

@athomaidis, alles klar, mache ich gleich.

Danke Dir.

Tut er doch gerade nicht. Die Server-Version lautet 2.0.0i1 und da sollte doch auch der Agent eine i1 melden – zumal, wenn er per Bakery ausgerollt wurde.

Ich habe gerade im Repo nachgeschaut: Die Version, die mit 2.0.0i1 getaggt ist, liefert auch 2.0.0i1. Hast Du evtl. eine Version vom “master” (d.h. daily build) benutzt? Da ist die Versionsnummer schon auf i2 hochgedreht.


ich habe dieses hier heruntergelade /installiert:

das ist die “richtige” oder?

Hi, the problem has been identified (a 2.0.0i2 Windows agent is in inside the 2.0.0i1). Thanks for the feedback mail Mela.
If there are any specific issues/bugs/questions with the innovation release, please use the feedback mail provided above. If you have an issue, where you want feedback/help from the community, please open a new thread in the General or Troubleshooting category. Thanks!


greate, thanks @martin.hirschvogel .

Dear Martin, is it possible to install CEE 2.0.0i1 on the same server we‘re running CRE 1.6 on?

Yes, that’s the benefit of omd. The sites should be independent of each other.
