Promise

The Promise Storage Area Network (SAN) is capable of sending SNMP traps to remote destinations. Unfortunately, Syslog is not supported on these units.

Log sample
2654  Fan 4 Enc 1    Info     Apr 27, 2017 19:08:48 PSU fan or blower speed is decreased

There is a single management interface no matter how many shelves are installed, so configuration only needs to be performed once from the Promise web interface or the command line.

More information about configuring Promise arrays is available in the E-Class product manual. Also, additional details on CNMP configuration and links to MIB files are available in the following KB article.

  1. Configure NXLog for receiving SNMP traps (see the example below). Remember to place the MIB file in the directory specified by the MIBDir directive. Then restart NXLog.

  2. Make sure the NXLog agent is accessible from the unit.

  3. Configure Promise by using the web interface or the command line. See the following sections.

Example 1. Receiving SNMP traps from Promise

This example shows SNMP trap messages from Promise, as received and processed by NXLog.
