Q: What specific information does the Cloudamize agent collect?
A: The Cloudamize agent collects system and application related performance and usage metrics such as CPU, memory, disk, network and running applications.
Q: How does the Cloudamize agent connect to the Cloudamize server?
A: The Cloudamize agent sends data to the Cloudamize server over SSL (port 443).
Q: Do I need to open firewall to send data to the Cloudamize server?
A: Yes, the Cloudamize agents send data to the Cloudamize server over SSL (port 443). You need to make sure that outbound SSL (port 443) access is permitted to the Cloudamize server. You will not need to open firewall access if you are using Internet proxy.
Q: What if my physical servers do not have direct access to the Internet?
A: If your physical servers have Internet proxy access, Cloudamize agents will still be able to relay data via your Internet proxy to the Cloudamize server.
Q: Is there a proxy available to forward data from the physical machines that are not directly accessible by Internet?
A: No, there is not a proxy that is available to forward data from the physical machines that are not directly accessible by Internet.
Q: Is the Cloudamize agent a standalone executable (i.e. libc) or does it need Java or another framework preinstalled?
A: For Linux server hosts and VMs, the Cloudamize agent is a standalone binary executable. For Windows servers and VMs, the Cloudamize agent requires .NET framework 2.0 or greater.
Q: What is the performance overhead of running agents on physical servers?
A: The Cloudamize agents are lightweight. Typically it takes less than 0.5% CPU utilization. Cloudamize Agents are Smart Agents. They run two processes. One is the data-collection agent and the other is the watchdog agent. Watchdog agent monitors the data-collection agent and makes sure the data-collection agent is behaving correctly. Watchdog agent monitors every system metric and caps the data-collection agent if it goes beyond expected consumption. If any of the metric is higher than the cap, then data-collection agents sleeps and waits until they can start collecting again. For example, typically, our agents take less than 0.5% CPU utilization. However, if CPU utilization goes higher than 2%, data-collection agents sleeps and waits for watchdog-agent's to tell when to start collection again.
Q: What is the data collection frequency?
A: Cloudamize agents collects data every 30 seconds and pushes it out to Cloudamize server every 5-min.
Q: Can agents be installed on virtual machines without also collecting data from the hypervisor such as vCenter or the Hyper-V host machine?
A: Most performance metrics can be collected from the agent even when the agent is running on a VM and no data is being collected from vCenter. However, there can be some inaccuracy when estimating the CPU utilization. This inaccuracy can lead to an overestimate of the required computational needs, and can result in Cloudamize recommending a larger machine than necessary. However, this is only an issue when the physical server is under provisioned. In any case, memory and IO requirements are estimated correctly. To understand the issue, suppose that two VMs are running on a physical server that has a single CPU with a single one hardware thread. If both VMs are demanding the entire CPU, the hypervisor will allocate 50% of the compute time to each VM. However, from the perspective of a the VM and our agent on the VM, the CPU is 100% utilized. Since the agent sees the CPU 100% utilized, while the CPU is actually only 50% utilized, the Cloudamize agent will over estimate the computational requirements of the VMs. If this scenario occurs frequently, then it could lead to Cloudamize recommended a larger machine than is necessary. On the other hand, if CPU utilization data is collected from the hypervisor, then the actual CPU utilization is measured and an accurate estimate of compute requirements is made.
Q: How much bandwidth is used when the data is transported from Cloudamize agents?
A: Windows/Linux agents are approximately 5KB to 40KB per 10 minutes.
Q: Can I import the data rather than run an agent?
A. No. Cloudamize reads data from vCenter’s read-only APIs. For non-VMWare environment, Cloudamize provides a proprietary agent that can be installed for data collection and can be removed after the data collection period is completed.
Q: What is the methodology in obtaining the ‘Software Installed’ on each node? Is the Cloudamize Agent or ADC looking for EXE files, running processes, other methods?
A. The installed app list comes from the registry in Windows, basically, the list of apps that appear when you open add/remove programs. We use the rpm/deb database on Linux to list all packages installed on the system.
Q: Will Cloudamize continue using Admin to operate during assessment duration?
A. Yes, Cloudamize Windows Agent will continue to use SYSTEM account whenever it is running.
Q: Can an user provide custom role for necessary permissions?
A. No, Cloudamize Windows Agent will use only SYSTEM account.
Q: Can all update, install and download functions be deactivated in the agents?
A. Agents do not automatically update, download or install once installed. This must be triggered manually.
Q: How does the distribution of the agents work? Which accounts and rights are used?
A. Agent software is provided as-is, our guides can be used. Mass-installation is not supported by Cloudamize, but commonly done by scripting, SCCM, etc.
Q: For ADC Where are credentials stored, Only on the data collector VM, or are they saved to Cloudamize in the console?
A. They are stored on C:\Program Files (x86)\CloudamizeAgentlessDC\HostInfo.xml or HostInfoBackup.xml, Only on the data collector VM.
Q: Will CloudAmize help to discover the MS SQL database and application mapping? (When I discover the database name, will I be able to get the Application details running on the database, for eg: Application Host Name, Application IP address)?
A. Yes, for the details that will be collected by Cloudamize for the MS SQL data on our Knowledge base https://support.cloudamize.com/kb/Agentless-Overview.36852924700.html under Supported MS SQL data collected by Agent-Based and Agentless.
Q: What is the minimum version on OpenSSL/TLS that is supported by the current Cloudamize agent?
A. Cloudamize supports TLS 1.2 and above versions. The TLS version below 1.2 is not supported due to security reasons. Cloudamize Agent is currently using version 3.0.13. for the OpenSSL. The minimum required version of openSSL is 1.1.1 or higher.
Q: Does the watchdog restart the agents too or does it only kill the agents?
A. The watchdog will restart the Agent on a periodic basis if it determines the environment has enough resources for the Agent to run without interfering in normal operations.
Q: Would it be possible to download the actual agent installers prior (Windows and Linux) since our ops team wants to distribute the install packages early?
A. Installation of actual agents to collect data for an assessment requires a customer key that is only issued upon the opening of the console account. A free demo account can be provided that will give access to the Agent download and installer, but the dummy key will result in any gathered data being discarded upon receipt, and once you have the actual customer key you would have to uninstall and re-install again on all infrastructure using the customer key.
Q: Agentless data collector is limited to 500 hosts per subnet. How would you scale the data collector to deal with a larger subnet? Is it a vertical scale, or a horizontal scale?
A. We recommend increasing number of Agentless Data Collector. To scale the Cloudamize Agentless Data Collector to handle more than 500 hosts, it is recommended to use a horizontal scaling approach by installing additional data collectors on separate machines. Each data collector can monitor up to 500 hosts, so for larger environments, it is highly recommended to deploy multiple data collectors across different machines.
Q: Can we schedule the data upload from data collector server to cloudamize SaaS server on any time which clients wish to schedule?
A. Cloudamize does not support a data upload schedule that the customer can set up. ADC has its own schedule and sends data with best effort.
