Checking ifHighSpeed is likely the easiest if you don’t already have syslog set up.

 

My 200G LAGs show ifHighSpeed=>200000, so it would be easy to check if it’s < 200000, or != 200000 depending on how you want to write the check.

Syslog should show it. Just have to verify the text when a member drops and send alert out

I'm looking at an easy way to send an alert if a LAG member drops.

Running subscription Observium 22.12.12421 and talking a Juniper EX4500 switch.

My thought was to have a global check that looked for ifType = ieee8023adLag
and then if there was some way members changed, but I don't see a way to
detect/check for this.  I don't think Observium has any graphing on the LAG
port members state.  BTW, this would be a great thing to add to have viability
into LAG members at the ae level.

Perhaps checking if ifHighSpeed goes down?

Other than putting up check on the underlying interfaces manually, does anyone
have an idea on this?

Thanks,
