There is a set of information made available by vCenter through the WebServices API that the vmware probe does not present by default. The collection of information is known as HostNumericServerInfo, or sometimes NumericServerInfo in the literature. This includes information about server fans, running temperatures, power supplies, etc. UIM does not present this for monitoring by default. There is a configuration hand-edit that can enable the data for monitoring. This document will explain how to enable these monitors. However, there are some reasons the monitors are disabled by default. That discussion will be considered first.
- Host Numeric Sensor info not supported via the Admin Console
IMPORTANT: Host Numeric Server Info monitoring is ONLY available when using the Infrastructure Manager (IM) and is NOT available/accessible via the web Admin Console.
In larger environments which commonly use the vmware probe for storage monitoring of hundreds or thousands of ESX Hosts, it is NOT recommended to use IM, as the Admin Console scales and performs much better than the Infrastructure Manager for the vmware probe. Normally the vmware probe needs very large min and max memory setting values just to operate in a somewhat acceptable manner. It can get bogged down easily in IM, so we highly recommend using the Admin Console as the preferred method of vmware probe administration and configuration.
In the Admin Console, the Template Builder and ability to copy templates from one environment to another, e.g., DEV to Production, is a great advantage.
vmware configuration using IM versus AC
In the vmware raw configuration, if you set enable_bulk_configuration = false then you use IM to configure the vmware probe.
If you set enable_bulk_configuration to a value of pobc, it defaults to using the web-based Admin Console.
