Configure the cluster for SNMP monitoring

You can configure your Isilon cluster to remotely monitor hardware components using SNMP.

Before you begin

When SNMPv3 is used, OneFS requires the SNMP-specific security level of AuthNoPriv as the default value when querying the cluster. The security level AuthPriv is not supported.

About this task

You can enable or disable SNMP monitoring, allow SNMP access by version, and configure other settings, some of which are optional. All SNMP access is read-only.

The Isilon cluster does not generate SNMP traps unless you configure an event notification rule to send events.

Procedure

  1. Click Cluster Management > General Settings > SNMP Monitoring.
  2. In the SNMP Service Settings, click the Enable SNMP Service check box. The SNMP service is enabled by default.
  3. Download the MIB file you want to use (base or trap).
    Follow the download process that is specific to your browser.
  4. Copy the MIB files to a directory where your SNMP tool can find them, such as /usr/share/snmp/mibs/.
    To have Net-SNMP tools read the MIBs to provide automatic name-to-OID mapping, add -m All to the command, as in the following example:
    snmpwalk -v2c -c public -m All <node IP> isilon
  5. If your protocol is SNMPv2, ensure that the Allow SNMPv2 Access check box is selected. SNMPv2 is selected by default.
  6. In the SNMPv2 Read-Only Community Name field, enter the appropriate community name. The default is I$ilonpublic.
  7. To enable SNMPv3, click the Allow SNMPv3 Access check box.
  8. Configure SNMP v3 Settings:
    1. In the SNMPv3 Read-Only User Name field, type the SNMPv3 security name to change the name of the user with read-only privileges.
      The default read-only user is general.
    2. In the SNMPv3 Read-Only Password field, type the new password for the read-only user to set a new SNMPv3 authentication password.
      The default password is password. We recommend that you change the password to improve security. The password must contain at least eight characters and no spaces.
    3. Type the new password in the Confirm password field to confirm the new password.
  9. In the SNMP Reporting area, enter a cluster description in the Cluster Description field.
  10. In the System Contact Email field, enter the contact email address.
  11. Click Save Changes.
