Sensu-go: Windows based Sensu-Agent does not work with Linux based Sensu-Backend

[marcseguin]

I installed an testing environment as described in the https://docs.sensu.io/sensu-go/5.0/installation/install-sensu/.
The sensu-backend runs on Linux (CentOS 7.5) while sensu-agents run on Linux (still CentOS 7.5) and Windows (Server 2016)

Expected Behavior

Windows based sensu-agents can be used.

Current Behavior

Windows based sensu-agents can not be used.

While Linux based sensu-agents can register on the sensu-backend, the Windows based sensu-agents can't. They do not appear in the dashboard and the sensu server logs error messages:

Nov 25 15:26:01 srv-mon01.ks.netoffice-kassel.de sensu-backend[1587]: {"component":"keepalived","error":"entity name must not be empty","level":"error","msg":"invalid keepalive event","time":"2018-11-25T09:26:01-05:00"}

The error messages only appear when the Windows sensu-agent sends something to the sensu-backend.

Possible Solution

I'm not sure but I believe that the Windows based sensu-agent is too old and transmits wrong data to the sensu-backend. (Maybe related to issue #2308)
The as download offered Windows based sensu-agent is rather old, please provide an up to date one; best would be to includes Windows based sensu-agents into the build and provisioning process.
BTW: The download is not downloaded as executable (.exe) it is necessary to rename it after the download (no big deal but still a small hick-up)

Steps to Reproduce (for bugs)

Follow the installation guide https://docs.sensu.io/sensu-go/5.0/installation/install-sensu/

The windows agent we released is quite old. We haven’t yet started building them again, but we do intend to have them available soon (likely this week or next).

@grepory thx for the quick reply but I’m wondering why the issue is closed before the announced solution is available.

We can reopen it if you like. I will try to provide a timely update when we have windows packaging, but the community Slack, and Twitter are usually more timely channels for updates.

@grepory thank you very much. And thank you for the hint to slack. I will have a look to subscribe there as well.

Absolutely. I don’t know if it shows it in this ticket, because it’s in a private repo, but I linked our windows packaging ticket to this so when we close that, well follow up here.

for anyone watching this, looks like the binary is available and linked in docs, and works without issue. Wheeee : D

[marcseguin]

I got the first connection sucessfully. THX!
