Key Attributes:

Name Id Type Description
Event Type eventType string Event type set to PH_DEV_MON_NET_INTF_UTIL
Event

Severity

eventSeverity uint16 Set to 1. In general, a number between 0 (lowest severity) and 10 (highest severity)
Event

Severity

Category

eventSeverityCat string Set to Low. IN general, takes the values Low, Medium and High. Event Severities 0-4 are mapped to Low, 5-8 are mapped to Medium and 9-10 are mapped to High
Event

Receive

Time

phRecvTime Date Time at which AccelOps generated this event
Reporting IP reptDevIpAddr Date IP address of device reporting this event. In this case set to the device reporting the utilization (same as Host name attribute)
Relaying IP relayDevIpAddr Date IP address of device relaying this event from the source to AccelOps. In general it could be a syslog-ng IP address but in this, since AccelOps talks to the device directly, Relaying IP is set to AccelOps IP Address.
