Monitor ESXi or vCenter 5.0.0 with PRTG 9.2.0

Hello,

are the necessary credentials provided in the 'Settings'-tab of the group/device in PRTG?

best regards.

Hello,

yes.

when i go to the vCenter Server and add a new sensor it showes me "the parent device must be a VMware ESX or vCenter Server.."

but how can i configure a ESXi Host as a Child Host from a vCenter Host? The Parent Element is always a Group Element.

regards

On the vcenter-Server device you only add sensors, no other devices. You can add sensors for the virtual machines and also for the ESX(i)-hosts there. But you need to use your active directory credentials and apply them in PRTG in the settings of the parent device.

I can't select the ""VMware Host Server (SOAP)" or "VMware Virtual Machine (SOAP)" on my vCenter Server. For testing i used my Domain administrator login under the settings "Inherit Credentials for Windows Systems "of the vCenter server. i use this credentials when i work with vSphere Client on my vCenter Server.

on a ESXi Host i can select the sensor's but i receive an error "[prtg] [error]2[/error] [text]The session is not authenticated.[/text] [/prtg] " but i think that i s a snmp misconfiguration on ESXi side.

I can't select the ""VMware Host Server (SOAP)" or "VMware Virtual Machine (SOAP)" on my vCenter Server. For testing i used my Domain administrator login under the settings "Inherit Credentials for Windows Systems "of the vCenter server. i use this credentials when i work with vSphere Client on my vCenter Server.

I have now activated snmp on ESXi with the Vmware vSphre CLI commandline vicfg-snmp.pl script. then i try some configurations in PRTG but receive always an error "[prtg] [error]2[/error] [text]The session is not authenticated.[/text] [/prtg] "

i try all ESXi Logins, try http and https settings , try our snmp community name and the public name. try all snmp versions 1,v2c,v3 bot no luck.

with telnet from PRTG server to ESXi on port 161 the connection failed. the firewall setting on the ESXi host is set to allow incoming traffic for SNMP on Port 161(UDP)

please enter the same admin credentials in

Credentials for VMware/Xen server.

in your vCenter Server device.

Then please try again.

I try the same admin credentials "Credentials for VMware/XEN Servers " and for "Credentials for Windows Systems" but the same error.

My configuration is now this:

Group "MyvCenter": - Credentials for Windows Systems Domain or Computer Name: mydomain Username: myusername (this user is a domain admin) password: xxxxx - Credentials for VMware/XEN Servers User: mydomain\myusername Password xxxxxxx VMware Protocol HTTPS (recommended)

-Credentials for Linux (SSH/WBEM) Systems Username: admin (a local login on ESXi) Login: Login via Password Password: xxxxxx For WBEM Use Protocol: HTTPS For WBEM Use Port: Set automatically (port 5988 or 5989)

Under this group i add my ESXi Host and inherit all Login data's from group "MyvCenter". When i select a new sensor "VMware Host Server (SOAP)" or "VMware Virtual Machine (SOAP)" on this ESXi host i receive the error:

[prtg] [error]2[/error] [text]The session is not authenticated.[/text] [/prtg]

Hallo,

if you are adding virtual machine sensors or VMware host server sensors top your vCenter server device, your domain credentials have to be used in the credentials for VMware/Xen server

If the device you are trying to add sensors to is your ESX host itself, the credentials have to be used that you do normal use in your vSphere Client to log on to the server.

please open a ticket with support @paessler.com and maybe send some screenshots or provide access to your PRTG web interface so that we can take a look at it.

thx

When i use the vCenter credentials for the "Credentials for VMware/XEN Servers " i can add the "VMware Host Server (SOAP)" and the "VMware Virtual Machine (SOAP)" sensor to my vCenter Server.

that's fine for me.
