Benefits of agent-based monitoring
Even though Dell EMC's yx2x and later generations of PowerEdge servers can be monitored through the agentless (iDRAC) method,
agent-based (OMSA) method has the following benefits:
Alert generation capabilities of OMSA and iDRAC are not the same. In Dell EMC's yx3x or later generation of PowerEdge servers, the
alert generation capabilities of OMSA and iDRAC are almost similar. However, alerts from chipset and software RAID are available only
through OMSA.
For devices with a ProSupport Plus, ProSupport Flex for Data Center, or ProSupport One for Data Center service contract Dell EMC's
recommendations for operating system and software component versions are available only if the device is monitored through OMSA.
OMSA is the only option available for monitoring x9xx to yx1x generation of PowerEdge servers.
Support for automatically installing or upgrading
OMSA
To monitor a device through the agent-based method, SupportAssist Enterprise requires the OpenManage Server Administrator (OMSA)
agent to be installed and running on the device. The OMSA agent is an application that monitors the health of various components of the
device where it is installed. When OMSA is installed and running on a device, the OMSA agent generates an alert whenever a hardware
event occurs on the device. SupportAssist Enterprise receives the alert from the device and processes the alert to identify if the alert
indicates a hardware issue. For more information on OMSA, visit Delltechcenter.com/OMSA.
NOTE:
The SupportAssist Enterprise recommended version of OMSA may vary depending on the generation of the
PowerEdge server and the operating system running on the server. For information on the recommended versions of
OMSA, see the
SupportAssist Enterprise Version 2.0.50 Support Matrix
at Dell.com/ServiceabilityTools.
SupportAssist Enterprise has the capability to automatically download and install the recommended version of OMSA on a device. By
default, when a server is added for agent-based monitoring, SupportAssist Enterprise verifies if the recommended version of OMSA is
installed on the device.
If OMSA is not installed on the device, SupportAssist Enterprise prompts for your confirmation to download and install the
recommended version of OMSA on the device. On confirmation, SupportAssist Enterprise downloads and installs OMSA in the
background. The OMSA installation status is displayed in the Status column on the Devices page. If you choose not to install OMSA,
the status of the device is displayed as
OMSA not installed. To install OMSA at a later time, you can use the Tasks > Install /
Upgrade OMSA option on the device overview pane.
If OMSA is already installed on the device, SupportAssist Enterprise verifies if the version of OMSA matches with the recommended
OMSA version for SupportAssist Enterprise. If the existing version of OMSA is not the recommended version, but supports direct
upgrade to the recommended version of OMSA, SupportAssist Enterprise prompts for your confirmation to download and upgrade
OMSA on the device. The OMSA upgrade status is displayed in the Status column on the Devices page. If you choose not to upgrade
OMSA, the status of the device is displayed as
New version of OMSA available. To upgrade OMSA at a later time, use the
Tasks > Install / Upgrade OMSA option on the device overview pane.
NOTE:
Direct upgrade to OMSA version
n
is supported only from the two previous versions
(n-2)
of OMSA. If direct
upgrade is not supported, you must manually download and upgrade OMSA on the device. For example, if OMSA
version 7.0 is already installed on the device, but the recommended version of OMSA is 7.4, you must manually
upgrade from OMSA version 7.0 to 7.2. After upgrading to OMSA version 7.2, you can upgrade to OMSA version 7.4
using the More Tasks > Install/Upgrade OMSA option on the device overview pane or you can manually download and
upgrade to OMSA version 7.4.
NOTE: When you allow or use SupportAssist Enterprise to install or upgrade OMSA, the downloaded packages of OMSA
are retained in the SupportAssist Enterprise installation folder. If a compatible version of OMSA was already
downloaded during an earlier operation, SupportAssist Enterprise does not download OMSA again. In this scenario,
SupportAssist Enterprise only installs or upgrades OMSA on the device using the already downloaded version of OMSA.
NOTE: The time taken to download OMSA is dependent on the internet download speed and network bandwidth.
