Is there a way to select a single row from a MIB table? The table I'm interested in has one entry for each sensor, but I am only interested in the value from one of the sensors, to be used in a summary chart.
Yes, you need to specify the row with the OID.
Can you give a syntactical example?
We use Ruckus WiFi access points. To display the channel assignments for all SSIDs, we use GET TABLE with OID 1.3.6.1.4.1.25053.1.1.6.1.1.1.1.1.9
If we just wanted to poll the channel assignment for the SSID with a row ID of 5 in the table, we would use GET with OID 1.3.6.1.4.1.25053.1.1.6.1.1.1.1.1.9.5
In other words, just add the RowID for the item you want to the end of the OID and use GET instead of GET TABLE to poll the value from just that one row.
