GenesisNX2 offers additional SNMP values to monitor Pool and ZFS attributes.<br/>It is necessary to query specific OIDs in order to receive those attributes.


For basic ZFS parameters NYMNETWORKS-MIB mib is included ([[Ftp:ftp://software:UuPpDdAaTtEe@ftp.Scale_Logic.com/Downloads/NYMNETWORKS-MIB.txt|NYMNETWORKS-MIB):]]

This function enables you to configure access over the SNMP protocol in versions 2 or 3.

With SNMP enabled, you receive a wealth of information (CPU usage, system load, memory info, ethernet traffic, running processes).
System location and system contact are only for your information.  For example, when you connect from an SNMP client, you will see your location and name.

SNMP, version 3 has an encrypted transmission feature as well as authentication by username and password.
SNMP, version 2 does not have encrypted transmission, and authentication is done only via the community string.

The community string you set can contain up to 20 characters, while the password needs to have at least 8 characters.

Links to SNMP clients:

Note:

Our storage system supports the SNMP protocol in MIB-II standard.  List of MIBs:

  • - mib-2.host
  • - mib-2.ip
  • - mib-2.tcp
  • - mib-2.udp
  • - mib-2.interfaces
  • - mib-2.at
  • - system

GenesisNX2 offers additional SNMP values to monitor Pool and ZFS attributes.
It is necessary to query specific OIDs in order to receive those attributes.

For basic ZFS parameters NYMNETWORKS-MIB mib is included (NYMNETWORKS-MIB):

snmpwalk -v 2c -m NYMNETWORKS-MIB -c community 192.168.251.79 .1.3.6.1.4.1.25359.1

Additional information, like compression ratio, deduplication ratio, available space (in bytes), age (in seconds) of youngest snapshot on volume,
can be obtained with standard NET-SNMP-EXTEND-MIB:

Examples:

NET-SNMP-EXTEND-MIB::nsExtendOutputFull."deduplication" = STRING:

"deduplication Pool-0 1.00"

NET-SNMP-EXTEND-MIB::nsExtendOutputFull."compression" = STRING:

"compression Pool-0/vol00 1.01
compression Pool-0/clone-vol00 1.00"

NET-SNMP-EXTEND-MIB::nsExtendOutputFull."volumes_list" = STRING:

"available Pool-0/vol00 11981377536
available Pool-0/clone-vol00 11981377536"

NET-SNMP-EXTEND-MIB::nsExtendOutputFull."snapshots_age" = STRING:

"snapshot_age Pool-0/vol00 3
snapshot_age Pool-0/vol01 371"
