Linux & Unix Server Auto-Discovery
Beginning with version 13.2.0, Device42 supports ssh-based linux and unix discovery from within the main appliance. For a full list of supported *nix operating systems please visit Device42 Supported Operating Systems
Setting up Linux/Unix auto-discovery
Prior to configuring an ssh-based discovery job please be sure you have your SSH port (standard TCP port 22, or custom port) open between your Device42 Main Appliance or Remote Collector and the targetted unix/linux servers.
From Tools > Auto-discovery > Hypervisors/*nix/win, you can add a *nix discovery job to connect and gather host and VM details:
On the “Add Hypervisors/*nix/win for Autodiscovery” page, choose *nix as the platform. Other options are as follows:
URL Prefix: This will be https in most cases. But, if you have changed it, you have the option to switch it to http.
Server : This is the FQDN or IP of the vCenter server or the ESX server. If using FQDN, device42 should be setup for DNS resolution(vm console, option 1)
End IP Address : Optional, if doing discovery on a range of servers rather than a single server.
Port : This will be 22 by default. Only change if you have a different ssh port configured.
Username & password: self explanatory. Use username with permission to connect to the linux/unix targets with SSH. For details about the level of user permissions required for linux/unix discovery please refer to our Linux Permissioning Guide.
Strip domain suffix : Checking this will strip domain suffix from discovered servers.
Give Precedence to Hostname : Check this option to give precedence to the discovered hostname. Debug Level : Debug On for extra debug info, useful for a support ticket.
There are a few other options that are geared toward hypervisor discovery and can be ignored for WinRM discovery.
Last status : Last run task status.
Run report: This will record what has changed in the last task.
Schedule for auto-discovery: You can schedule the discovery to run at certain times.
Run *Nix SSH discovery
Upon save(if you haven’t scheduled the discovery), you can run it from list, view or edit page using “Run now” button or link.
You can schedule the auto-discovery to run on a recurring basis. Specifically, you can choose to have it run on certain days of the week and at a specific time each day.
