Polling of discovered Dell devices
In the Dell OpenManage Connection for ITNM IP Edition, polling of the discovered Dell devices is a
mechanism to monitor their global health status, using specific polling policies and polling definitions.
The health status of the polled device is displayed in the Network View and Hop View in the following
format:
• Critical — Event that indicates loss of data or function such as a hardware failure.
• Normal — Event with successful operation of a component such as a power supply turning on.
• Warning — Event that may indicate a possible future problem such as crossing a warning threshold.
NOTE: The Store Poll Data option is not available.
If the health of a device turns from one status to the other, the latest status overwrites the previous status
of the device.
For polling DCLM, make sure that the Dell OOB servers are discovered on the systems and the DCLM
parameters are configured. Based on the number of available licenses, the possible status of DCLM is:
• DCLM critical — License is not available.
• DCLM warning — License has reached the limit, but system is running with a grace license.
• DCLM normal — License is available.
On Dell OEM servers, polling can be done through both the in-band and out-of-band (OOB)
mechanisms. You can enable or disable only the in-band polling on the Dell OEM servers.
On 10th and 11th generation of Dell PowerEdge servers or PowerVault NX Storage Arrays, the polling is
done through the in-band process, but on the 12th and 13th generation of Dell PowerEdge servers or
PowerVault NX Storage Arrays, or Dell workstations, the polling can be done through the in-band and
out-of-band (OOB) mechanisms. You can enable or disable only the in-band polling on the 12th or 13th
generation of Dell PowerEdge servers or PowerVault NX Storage Arrays, or workstations.
For polling Dell servers or workstations running ESXi, if the server is not reachable or WS-MAN
communication fails, then a minor alert is generated. This alert is cleared by the next polling alert if the
device is reachable and the WS-MAN communication is established.
If the EqualLogic device or the S-Series switch is not reachable or SNMP communication fails during the
polling, then a minor alert is generated. This alert is cleared by the next polling alert if the device is
reachable and SNMP communication is established.
If the Dell PowerVault MD Storage Arrays (with no SNMP support) is not reachable during the polling, a
minor alert is generated. This alert is cleared by the next polling alert if the device is reachable.
