Re: [Devmon] exception template to alarm only if ifAliasBox contains string "uplink"

[Oliver <r.o...@we...>]

Hallo,

I currently use another solution, that is not fully does, what I need, 
but is good for now:

ifAliasBox : only : .*uplink.*

This line causes that only interfaces are listed, which hold the word 
"uplink" in their alias field.

Thank you for your answers! I will come back to your hint with forming 
another table.

You said, that only the primary oid is valid for alarm definitions. Is 
the primary one the first line in the oids file the corresponding 
template? If so, would you think it is possible to simply switch ifName 
with ifAlias and then use one of my alarm definition from my first message?

Regards

Oliver

Thus lines in file exceptions starting with name other than the primary OID name are ignored. Thus, if I am right, you cannot enable or disable alarms based on the value of any of the other fields shown in the table.

You'll need to copy the variable(s) of interest to other variables, using the CHAIN operator. In this table you can enable alarms on all entries. Note however, that a switch without any uplinks will have an empty table. I do not know how Devmon will cope with that.

This script would take information from the tests if_stat and If_load, select only the links to other networking equipment (switch, router, AP) and alarm on being down, and alarm on ingress being zero while egress is not. (This script does handle an empty set of uplinks correctly.)
