Filter on interface SNMP discovery rule

[SupportGuy]

Hello,

Sorry if this point has already been answered, up to now I've not found the response to my question.

I have to monitor the network trafic of a particular interface for an existing park of servers. Each server has dozen of interfaces.

The interface I want to monitor is not the same on whole servers. the only common point is the naming rule.

I would like to know if it is possible to make filtering on the SNMP value in he discovery rule to retrieve only the item of a particular interface at the discovery rule level better thant in the item prototype level with something like, for the SNMP OID :
IF-MIB::ifAlias["MyIfAlias"]

Sorry for eventual disturbance, I've finally found the solution.

Using the "Filter" fields of the discovery rule, "Macro" and "Regexp".

In Macro I use {#SNMPVALUE} and in regexp, for example to only take in account interfaces which name is "MyInterfaceName", the string hereafter:
[^- .]MyInterfaceName$

Hello,

In my case i do not want to collect information for "Virtual-Access<ID>" interfaces on several routers we have. Whats the right regular expression to exclude this interfaces?



Thanks

Hello,

The solution is simple. I use expression ^Virtual to exclude Virtual-Access interfaces.

...which would then match *any* interface beginning with "Virtual".

To match Virtual-Access0 - Virtual-Access9:

^Virtual-Access\d{1}$

To match Virtual-Access0 - Virtual-Access99:

^Virtual-Access\d{1,2}$
