This is a real life sample alert from the leader in Proactive Network Management software: indeni.

Description:

Some NIC’s duplex is set to half instead of full. This may be an auto-negotiation error.

indeni will re-check this alert every 1 minute. If indeni determines the issue has been resolved, it will automatically be flagged as such.

Affected NICs:

eth5 (Bandwidth: 100M/half, MAC Address: 00:1C:7F:31:23:D8)

Manual Remediation Steps:

Please ensure that all physical network connections are in place, all routers and switches are properly configured and identify any recent changes which may be causing this.

How does this alert work?

indeni monitors the critical stats of all network interfaces and ports constantly. When issues are found, such as half duplex (which, in reality, should almost never happen), indeni alerts and attempts to provide as much information as it can.

Get this and thousands of other checks performed algorithmically, 24/7/365.
