Retrieving NSX-T gzipped logs from appliances

[mafteiu]

Hi,

I am trying to retrieve archived logs from Edge appliances using REST API (NSX-T 3.2.2):

GET

URI Path(s):

/api/v1/transport-nodes/<transport-node-id>/node/logs/<log-name>/data

The problem is the downloaded .gz files are corrupted.

7zip would extract a few k (1 to 15k), then would fail with an error, gzip will directly return invalid compressed data--format violated without extracting anything. To note that the little amount of data extracted with 7z is readable.

I've tried using

invoke-webrequest, invoke-restmethod, System.Net.WebClient class - in pwsh 7.3

curl and wget in bash

Same result.

Has anyone succeeded in retrieving this?

Thanks.

Something interesting I noticed, in the REST API docs it says:

Response Code:

200 OK, 206 Partial Content

Response Headers:

FileRequestHeaders
Content-type: application/octet-stream

 

whereas a Fiddler trace shows:

Content-Type: text/html;charset=UTF-8
