Hi,
Going through the basics with this question... I'm looking for some guidance around configuring SNMP CONNECTION and SERIAL CONNECTION when creating a Microsoft Platform element.
Looking into the protocol.xml for various versions of Microsoft Platform and Microsoft Platform SNMP and loading into Cube, I'm assuming that the Microsoft Platform element has two connections (primary=SNMP and secondary=Serial) because the very first driver to manage Microsoft used purely SNMP, and as WMI got introduced, a serial connection was added. And SNMP was maintained mainly to retrieve server HW specific data (e.g.: Dell iDRAC and HP iLO data). This is just an assumption and I'll be interested to hear more about why two connection exists.
Questions (in the context of Microsoft Platform v1.1.2.x):
1) Do we always set the IP address of SNMP CONNECTION and SERIAL CONNECTION to the same IP address which is the IP address used to log into the Microsoft platform? (i.e.: driver is only designed to poll both Microsoft data via WMI and Dell iDRAC/HP iLO HW data via in-band SNMP)
2) Is there a situation whereby we would set SNMP CONNECTION to a different IP address to SERIAL CONNECTION? (I'm thinking is the driver designed to retrieve Microsoft data via WMI (serial) and Dell iDRAC/HP iLO HW data via out-of-band SNMP)?
I'll be keen to read any further info documented around this topic.
Hi Bing,
The objective of the second connection is to monitor additional parameters related to the hardware where the OS is running. Currently there are two vendor OIDs supported:
-
- HP ILO (1.3.6.1.4.1.232)
- Dell IDRAC (1.3.6.1.4.1.674.10892)
These servers comes with an extra controller that is used to access/control the servers remotely. The controllers have their own SNMP agents running on dedicated IP addresses. This means that the SNMP connection of the element will need to be set with the IP address of the iDRAC/HP ILO NIC card.
The purpose of this driver range (v1.1.2.x) is to monitor Microsoft OS running on a physical hardware. In case the HW is not supported, you could assign the same IP address of the serial (WMI) connection. The SNMP parameters are not enabled by default, so the driver will not execute any SNMP polling.
Ok, it is clear to me now. Thanks Miguel!
