The PowerScale OneFS operating system provides an inbound back-end Ethernet switch monitoring through the CELOG system. CELOG monitors, logs, and reports important events and error conditions on the node and cluster, including the back-end Ethernet switches. CELOG provides a single point from which notifications are generated, including sending alert emails and SNMP traps.
Monitoring event | Alert | Applies to | Frequency check | Description |
NODE_BE_SWITCH_MGMT_SERVICE | Failed to talk with back-end switch management {protocol} service on {ifname} | All Ethernet switches | Every 3 minutes | Determines the responsiveness of the back-end Ethernet switch management service. |
NODE_BE_SWITCH_FAN | Fan failure detected in switch {switch_serial} on {int} fabric | All Ethernet switches | Every 11 minutes | Determines the state of the back-end Ethernet switch's FRUs. |
NODE_BE_SWITCH_PWR | Power supply failure detected in switch {switch_serial} on {int} fabric | All Ethernet switches | Every 7 minutes | Determines the state of the back-end Ethernet switch FRUs. |
NODE_BE_SWITCH_FABRIC | {int} fabric error detected: {desc} {id} {switch_serial} | Only Dell switches | Every 5 minutes | Determines if there is back-end Ethernet miscabling and other validation errors reported by the fabric. |
NODE_BE_SWITCH_BANDWIDTH_DISCREPANCY | {int} fabric bandwidth discrepancy detected: {desc} {id} {switch_serial} | Leaf-Spine Only | Every 59 minutes | Determines if there is a discrepancy between total uplink and total downlink bandwidth on a leaf switch. |
NODE_BE_FABRIC_BANDWIDTH_INCONGRUENCE | Fabric bandwidth incongruence detected: {desc} | Leaf-Spine Only | Every 61 minutes | Determines if there is incongruity between total uplink (trunk) bandwidth between int-a and int-b fabrics. |
Besides these listed CELOG inbound alerts, users can also monitor the switches through SNMP MIBs. Dell Networking OS supports standard and private SNMP MIBs. For a list of MIBs supported in the OS10 version running on a switch, see the OS10 Release Notes and Guide.
