No really great turnkey software exists for this. There are many tools which can be used for specific types of monitoring + managing.<br />
<br />
Start by describing exactly what you'll be monitoring + managing.<br />
<br />
Tip: If you have 100s of Debian servers, likely most or all barely use any resource.<br />
<br />
A likely intermediate step will be to convert many of your machines to LXD containers.<br />
<br />
LXD allows slicing up physical machines into other physical machines, meaning LXD containers run at bare metal speed.<br />
<br />
Once I switched to LXD (back when it was LXC) my daily task load dropped greatly.

I tried Cockpit and I really liked it but it is limited to 20 servers.

<br />
Is it running up against a physical limit on the server that you're running it on? &nbsp;It's free open source, so it should be able to handle as many as you code or config it to run.

<div>
Maybe you installed cockpit from some odd source.<br />
<br />
Best to install cockpit from the actual Debian repository...<br />
<br />

<pre><code class="code-1 nolinks" id="code-20-42829034-1"><span>apt-get install cockpit</span>
</code></pre>
</div>


<div>
Ok, I will try to install it on a CentOS server. <br />
<br />
Thank you very much to both of you.
</div>


<div>
You're welcome!<br />
<br />
Good luck!
</div>


<div>
to manage them all use ansible <a href="https://www.ansible.com/" rel="ugc">https://www.ansible.com/</a><br />
to monitor use zabbix <a href="https://www.zabbix.com/" rel="ugc">https://www.zabbix.com/</a>

<div>
@CLR, be sure to update this question with what your determine is best tool to use.<br />
<br />
Your update may help out someone down the road.<br />
<br />
Thanks!
</div>


<div>
I think I will stay with Cockpit on a CentOS server. It is way better than running it on Debian.<br />
<br />
In the future, if I have the chance to start the infrastructure from the beginning, I will go on a container solution.<br />
<br />
Thank you for your help.<br />
<br />
Benjamin.

Hi everyone,<br />
<br />
I'm searching for a tool to manage and monitor hundreds of Unix servers. <br />
90% are on Debian but from Debian 7 to Debian 9.<br />
<br />
I tried Cockpit and I really liked it but it is limited to 20 servers.<br />
Webmin is not good enough.<br />
I tried to install a CentOS server with SpaceWalk on it but I can't take the control of Debian's servers.<br />
<br />
So I would like to know if you have some advice for me.<br />
<br />
Tank you all.

How to manage hundreds of Debian server ?

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

Installation is the act of making a computer program program ready for execution. Because the process varies programs often come with a specialized program responsible for doing whatever is needed for their installation. Installation may be part of a larger software deployment process. Cross platform installer builders that produce installers for Windows, Mac OS X and Linux include InstallAnywhere, InstallBuilder and Install4J. Installers for Microsoft Windows include Windows Installer, InstallShield, and Wise Installation Studio; free installer-authoring tools include NSIS, IzPack, Clickteam, InnoSetup, InstallSimple and WiX. Mac OS X includes Installer, and also includes a separate software updating application.

Installation

The variety of Linux distributions creates myriad issues relating to configuration and operations when computers are networked, not the least of which is the use of various network management applications, some of which are included with specific distributions, while others are standalone applications.
