PowerScale OneFS 9.2.1.0 CLI Administration Guide

Configure the cluster for SNMP monitoring

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

1. Enable SNMP monitoring.
   Run the following command to enable SNMP v2c and to set the SNMP community name. The default community name is I$ilonpublic. Ensure that you set the default community name when enabling SNMP v2c. OneFS supports SNMP v2c and later.

   isi snmp settings modify --snmp-v1-v2c-access yes -c <community_name>

   Run the following command to enable SNMP v3 and set the SNMPv3 private password:

   isi snmp settings modify --snmp-v3-access yes --snmp-v3-priv-password <your_private_password>

2. Start the SNMP service.

   isi snmp settings modify --service yes

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. Configure SNMP v3 settings.
   1. Change the default SNMPv3 security name and password for the read-only user.
      The default read-only user is general. The default password is password. It is recommended that you set the community name from the default. Ensure that you change both the SNMPv3 authentication and privacy passwords to improve security. The password must contain at least eight characters and no spaces.

      isi snmp settings modify -u <readonly-user> --snmp-v3-password <readonly-password>

   2. Set a system contact and a cluster description for reporting purposes. For example, to set the system contact to SysAdmin and cluster description to Production:

      isi snmp settings modify --system-contact SysAdmin --system-location Production
