Unable to view individual switch interfaces. Is this a tag misconfiguration?

Hello @DeMoB ,
Are you able to return data if you do:

SELECT derivative(mean("ifHCInOctets"), 1s) /1000000*8 AS "In", derivative(mean("ifHCOutOctets"), 1s) /1000000 *-8 AS "Out" FROM "snmp" WHERE ("hostname" = 'Server-Room-C-POE') AND $timeFilter GROUP BY time($interval)

With no fill?
I can’t see why adding a fill null would not allow you to view the results especially if you can select for all those values.
Does this work?

SELECT "ifHCInOctets"FROM "snmp" WHERE ("hostname" = 'Server-Room-C-POE' AND "ifName" = 'gi1/0/1') AND $timeFilter GROUP BY time($__interval) fill(null)

Or this?

SELECT "ifHCInOctets"FROM "snmp" WHERE ("hostname" = 'Server-Room-C-POE' AND "ifName" = 'gi1/0/1') AND $timeFilter GROUP BY time($__interval) 

That seems odd to me but I’m not that familiar with SNMP. @Jay_Clifford do you see something obvious here?
