Hi
I am using the Generic Cisco Device Extension to monitor Cisco devices. I am planning to use a metric event to detect interface link downs. I thought I could achieve this by monitoring the metric “com.dynatrace.extension.network_device.if.status”, but the value of this metric is always 1, and Link Up/Down is defined as a dimension. Is it possible to use this metric to detect link downs as a metric event?
@Shirai You can use these
Key: oper.status
Usage: The operational state of the interface (up/down/etc.).
Key: admin.status
Usage: The admin state of the interface (up/down/etc.).
@p_devulapalli-san. Thanks for the reply.
I understand that oper.status indicates Link up/down, but I don’t know how to define a change in oper.status as a metric event.
I tried the metric event setting screen below, but I was unable to set “oper.status” in the Metric key field.
@Shirai You can use the Dimension Filter along with monitoring strategy to set the threshold , please see below example
Let me ask a few more questions. In the configuration you provided, the Dimension value is set to “up(1)”. In this case, will it detect a link up or a link down?
