Step-by-step guide
Prerequisites
- A user with sufficient rights (the automation user would do out of the box)
...
- Checkmk's server hostname (or IP)
...
- The site which holds the agent
...
- The agent you want to download (i.e., OS & hash or hostname)
...
The easiest way for the latter to find the OS and has, is to navigate to the Agents section in Checkmk agent bakery and hover the cursor over the installation package:

If you're not able to fetch the hash via the browser, you can access it via cliCLI:

root@linux# su - mysite
OMD[mysite]:~$ ls var/check_mk/agents/linux_deb/_PACKAGESpackages/
0f5881c7d6ea8e111ae46a9ab42f290b 1ae46a9ab42f290b.conf 0f5881c7d6ea8e111ae46a9ab42f290b.sig d218f24da92c980a.conf8107877152463cf2 d6379f6fc8945c3d

wget
As you can see the HTTP call in the above screenshot is almost complete, sou you can just right-click on the package and say (depending on the browser): "Copy link" and then create the wget link out of it:
| Code Block |
|---|
wget "http(s)://<checkmkhost>/<site>/check_mk/download_agent.py?hostname=<hostname>&hash=c9394c3914cc6982&os=linux_tgz&_username=automation&_secret=<automation_secret>" -O agent.deb |
httpie, download by hash value
Install httpie on the system where you want to download the agent.
Create a script with the following content:
