Configuring SNMP settings

You can configure the system to make Object Identifier (OID) values available to Simple Network Management Protocol (SNMP) client applications. At the same time, you can receive status information or messages about system events in a designated trap. For information about environmental circumstances that are monitored by IBM® StoredIQ®, see the following table.

Procedure

  1. Go to Administration > Configuration > System > SNMP settings.
  2. To make OID values available to SNMP client applications, in the Appliance Public MIB area:
    1. Select the Enabled checkbox to make the MIB available, that is, to open port 161 on the controller.
    2. In the Community field, enter the community string that the SNMP clients use to connect to the SNMP server.
    3. To view the MIB, click Download Appliance MIB. This document provides the MIB definition, which can be provided to an SNMP client application.
  3. To capture messages that contain status information in the Trap destination area:
    1. In the Host field, enter the common name or IP address for the host.
    2. In the Port field, enter the port number. Port number 162 is the default.
    3. In the Community field, enter the SNMP community name.
  4. To modify the frequency of notifications, complete these fields in the Environmental trap delivery area:
    1. Send environmental traps only every __ minutes.
    2. Send environmental traps again after __ minutes.
  5. Click OK. Environmental traps that are monitored by IBM StoredIQ are described in this table.
    Option Description
    siqConsoleLogLineTrap A straight conversion of a console log line into a trap. It uses these parameters: messageSource, messageID, severity, messageText.
    siqRaidControllerTrap Sent when the RAID controller status is anything but normal. Refer to the MIB for status code information. It uses this parameter: nodeNum.
    siqRaidDiskTrap Sent when any attached raid disk's status is anything but OK. It uses this parameter: nodeNum.
    siqBbuTrap Battery Backup Unit (BBU) error on the RAID controller detected. It uses this parameter: nodeNum.
    siqCacheBitTrap Caching indicator for RAID array is off. It uses this parameter: nodeNum.
    siqNetworkTrap Network interface is not UP when it must be. It uses this parameter: nodeNum.
    siqDbConnTrap Delivered when the active Postgres connection percentage exceeds an acceptable threshold. It uses this parameter: nodeNum.
    siqFreeMemTrap Delivered when available memory falls too low. It uses this parameter: nodeNum.
    siqSwapUseTrap Sent when swap use exceeds an acceptable threshold. Often indicates memory leakage. It uses this parameter: nodeNum.
    siqCpuTrap Sent when processor load averages are too high. It uses this parameter: nodeNum.
    siqTzMismatchTrap Sent when the time zone offset of a node does not match the time zone offset of the controller. It uses this parameter: nodeNum.
