Alarm Overview

Last updated: 2020-10-30 15:19:11

    This document describes the metric alarms and event alarms for a connection, dedicated tunnel and direct connect gateway to help you configure alarm policies.

    Metric Alarms

    To create a metric alarm policy, you can configure the outbound bandwidth, inbound bandwidth, and bandwidth utilization as the trigger conditions for a connection; configure the outbound bandwidth and inbound bandwidth for a dedicated tunnel; and configure the outbound bandwidth, inbound bandwidth, outbound packet, and inbound packet for a direct connect gateway.

    Metric Description
    Outbound bandwidth Average outbound traffic of the connection/dedicated tunnel/direct connect gateway per second.
    Inbound bandwidth Average inbound traffic of the connection/dedicated tunnel/direct connect gateway per second
    Bandwidth utilization Current bandwidth divided by connection bandwidth * 100%.
    Outbound packet Average outbound packets of the direct connect gateway per second
    Inbound packet Average inbound packets of the direct connect gateway per second.

    Event Alarms

    You can use the DirectConnectDown event as the trigger condition of event alarms for a dedication. You can use the DirectConnectTunnelDown, DirectConnectTunnelBGPSessionDown, DirectConnectTunnelRouteTableOverload, and DirectConnectTunnelBFDDown events as the trigger conditions of event alarms for a dedicated tunnel.

    Event Name Event Parameter Event Type Dimension Recoverable Description Troubleshooting Method
    Connection downtime DirectConnectDown Exception Connection Yes The physical link of the connection is interrupted or has an exception 1. Check whether the physical link has an exception or is interrupted (for example, the fiber cable is cut off, the line is unplugged, etc.).
    2. Check whether the receiving port and optical/electrical modules are normal.
    3.Check whether the network device port is closed.
    Dedicated tunnel downtime DirectConnectTunnelDown Exception Dedicated tunnel Yes The physical link of the connection is interrupted or has an exception 1. Check whether the physical link has an exception or is interrupted (for example, the fiber cable is cut off, the line is unplugged, etc.).
    2. Check whether the receiving port and optical/electrical modules are normal.
    3.Check whether the network device port is closed.
    Dedicated tunnel BGP session downtime DirectConnectTunnelBGPSessionDown Exception Dedicated tunnel Yes The dedicated tunnel BGP session is interrupted 1. Check whether the BGP process of the network device is normal.
    2. Check whether the dedicated tunnel is normal.
    3. Check whether the physical line is normal.
    Alarm for exceeded number of BGP tunnel routes DirectConnectTunnelRouteTableOverload Exception Dedicated tunnel No The number of BGP session routes in a dedicated tunnel exceeds 80% of the threshold Check whether routes published by the BGP session of the dedicated tunnel have reached 80% of the maximum, which is 100 by default. For more information, see Resource Limits.
    Dedicated tunnel BFD detection downtime DirectConnectTunnelBFDDown Exception Dedicated tunnel Yes The dedicated tunnel BFD detection is interrupted 1. Check whether the dedicated tunnel is normal.
    2. Check whether the physical line is normal.
