Configure the cluster for SNMP monitoring

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

Before you begin

When SNMP v3 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.

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.

Note: 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 Service area of the SNMP Monitoring page, enable or disable SNMP monitoring.
    1. To disable SNMP monitoring, click Disable, and then click Submit.
    2. To enable SNMP monitoring, click Enable, and then continue with the following steps to configure your settings.
  3. In the Downloads area, click Download for the MIB file that you want to download. Follow the download process that is specific to your browser.
  4. Optional: If you are using Internet Explorer as your browser, right-click the Download link, select Save As from the menu, and save the file to your local drive. You can save the text in the file format that is specific to your Net-SNMP tool.
  5. Copy MIB files to a directory where your SNMP tool can find them, such as /usr/share/snmp/mibs/ or /usr/local/share/snmp/mibs, depending on the SNMP tool that you use. 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
  6. Navigate back to the SNMP Monitoring page and configure General Settings.
    1. In the Settings area, configure protocol access by selecting the version that you want. OneFS does not support writable OIDs; therefore, no write-only community string setting is available.
    2. In the System location field, type the system name. This setting is the value that the node reports when responding to queries. Type a name that helps to identify the location of the node.
    3. Type the contact email address in the System contact field.
  7. Optional: If you selected SNMP v1/v2 as your protocol, locate the SNMP v1/v2c Settings section and type the community name in the Read-only community field. The default community name is I$ilonpublic For security reasons, we recommend that you change the community name or disable the SNMP service.
    Note: OneFS no longer supports SNMP v1. Although an option for v1/v2c may be displayed, if you select the v1/v2c pair, OneFS will only monitor through SNMP v2c.
  8. Configure SNMP v3 Settings.
    1. In the Read-only user field, type the SNMP v3 security name to change the name of the user with read-only privileges. The default read-only user is general.

      The password must contain at least eight characters and no spaces.

    2. In the SNMP v3 password field, type the new password for the read-only user to set a new SNMP v3 authentication password. The default password is password. We recommend that you change the password to improve security.
    3. Type the new password in the Confirm password field to confirm the new password.
  9. Click Submit.
