Polling and SNMP Support

The following table lists the configurable values for polling and thread selection in the hwmgmtd.conf file when SNMP monitoring is used on the host.

Note:

The default configuration for polling provides the optimal functionality in systems where SNMP monitoring is not used. Where host-based SNMP monitoring is configured and the Oracle ILOM trap proxy setup using itpconfig, the Hardware Management Agent will perform an initial poll of Oracle ILOM and then listen for Oracle ILOM SNMP traps to decide when a re-pole is needed. Enabling SNMP polling threads increase resources used by the Hardware Management Agent which might affect system performance.

Thread	Description
storage_poller_enabled=<value>	When enabled, the Hardware Management Agent provides up-to-date information about host internal storage to Oracle ILOM. In addition, if SNMP monitoring is enabled on the host, this poller responds to host SNMP requests to the SUN-STORAGE-MIB. Supported values are: 0=disabled; 1=enabled. The default is 1. Note: Disabling this parameter is not recommended as it will prevent storage information from being sent to Oracle ILOM.
inventory_poller_enabled=<value>	When enabled, this poller responds to host SNMP requests to the SUN-HW-MONITORING-MIB. Supported values are: 0=disabled; 1=enabled. The default is 0.
request_thread_enabled=<value>	When enabled, the Hardware Management Agent responds to host SNMP requests and listens for SNMP traps generated by Oracle ILOM. Supported values are: 0=disabled; 1=enabled. The default is 0.
polling_round_delay=<time in seconds>	If needed, this option can be added. When set, this option overrides the default polling delay of every hour, or sooner if a trap is detected when using host-based SNMP monitoring and the Oracle ILOM trap proxy. You might want to add this option if you require more precise real-time data regarding sensor values (temperature/voltage). Set the default sleep time in seconds. Note: When using this option, Oracle recommends not setting it to anything under 60 seconds due to the additional use of system resources.
