Monitoring Oracle VM Manager
eG Enterprise provides a specialized monitoring model for the Oracle VM manager. Figure 1 depicts the Oracle VM Server model that eG Enterprise offers.
This is an ‘agentless’ model that requires the eG agent to be deployed on any remote Windows/Linux/Solaris host in the environment. This model constitutes a set of hierarchical layers, which are mapped to a wide variety of tests to determine the inside and outside views of VM performance. When the remote agent executes these tests, it pulls out a wealth of performance information about the VMs. Using the inside and outside views, administrators can find quick and accurate answers for the following performance queries:
- How many guest VMs are running on each Oracle VM server, what is the IP address of each of guests, what operating system is each guest running, and when was the guest powered on?
- Is the web services interface accessible? If so, how quickly can it be accessed?
- How much memory is allocated to each guest and does each guest VM have sufficient free memory?
- Is the control domain consuming resources optimally?
- Does the Oracle VM server have sufficient memory available to support the guest VMs that it is hosting?
- What is the CPU utilization of the Oracle VM server and which of the guest VMs is taking up excessive CPU?
- Which application(s) running on each of the guest VMs is taking CPU, memory, and disk resources?
- Is there sufficient disk space in each of the disk partitions of the guest operating system?
- Which of the guests is seeing the highest and lowest network traffic?
- Is there excessive queuing for disk access on any of the guest VMs?
