I did the installation going to "Setup > Add Target > Add targets Manually > Add Host Targets".
If I install a Linux agent by this way all OS metrics are successfully retrieved.
Didn't see any target promotion step... I only see a promotion step if the install is made by auto discovery procedure.
I did the installation via agent push.
If I go to "Targets > Hosts" the windows host is there... The OEM knows that there is a windows host in the env, so the management plug-in is probably there.
Let me explain you few operation in EM 12C:
*Discovering Unmanaged Hosts in Enterprise Manage
r*If you want to monitor additional targets on the host where you have installed Enterprise Manager Cloud Control, then skip this section. Such a host is already discovered and monitored as a managed host in Enterprise Manager Cloud Control. However, if you want to add other hosts that are currently not discovered and monitored in Enterprise Manager Cloud Control, then configure an automatic discovery of such unmanaged hosts, particularly using the IP scan. For instructions, access the following URL:
Note:The unmanaged hosts are discovered using an IP address scan. However, to convert the discovered unmanaged host to managed host, you have to promote it. When you click Promote, you are taken to the Add Host Wizard where you are required to install a Management Agent on that unmanaged host. For instructions, refer to Oracle Enterprise Manager Cloud Control Basic Installation Guide.
If the agent installation fails because the agent image is not available, then download the agent image as described in the following URL:
Configuring Automatic Discovery of Targets on Managed Hosts
After converting unmanaged hosts to managed hosts in Enterprise Manager Cloud Control, you must configure automatic discovery of targets on those hosts so that the unmanaged targets running on those hosts can be identified.
For instructions to configure automatic discovery of targets on managed hosts, access the following URL:
Checking For and Promoting Discovered TargetsOnce you have configured automatic discovery of targets on managed hosts, you must regularly check for discovered targets so that they can be promoted and monitored in Enterprise Manager Cloud Control.
For instructions to check for and promote discovered targets to managed status, access the following URL:
Note:The promotion operation takes care of deploying the corresponding target-specific plug-in to the Management Agent. This happens internally in the background. Therefore, you need not explicitly deploy the plug-ins to the Management Agent using EM 12c console
thanks for your explanation. But what I really need to know is if the Windows Agent 184.108.40.206.0 retrieve some OS performance metrics like CPU%, memory%, swap%, etc...
By the logs I successfully installed the agent and only very basic metrics about the host are being retrieved. I just want to know if this is normal.
Have anyone installed the Windows Agent 220.127.116.11.0?
What do you see on your Targets -> Hosts -> (Select Server) page?
I see CPU/Memory/File and Network Utilisation (%) graphs.
Selecting "Table View" for Memory Utilisation (for example) show % values being recorded at 5 minute (or less) intervals.
Target Host is Windows Server 2003 (x64). Target Database is 10.2.0.4 (x64). Target Agent is 18.104.22.168 (pushed from 12c CC Windows x64).
thanks for you response. That's the problem, all graphs are empty.
And if I go to "Host > monitoring > [all metrics] [metric collect settings]" on windows host page I don't see any performance metrics like I see in a Linux host.
My OEM 12c is installed on a Linux x86_64.
I don't know for sure what was causing the problem, but I did two things.
Synchronized the clock of the windows server and oms sever and added the flag nodosfilewarning on CYGWIN environment variable on .bash_profile of the user that connects to windows server.
export CYGWIN=$CYGWIN nodosfilewarning
Do this and reinstall the agent. If it don't work try to resync the agent.
