Availability according a variable

[Legacy User]

Hi there,

 

I am trying to extend a vendor certification but until now I only catch a new variable value but I don't know how to perform a calculation to give me the availability.

I explain:
The OperStatus must be 2, how can I calculate the availability of a device component (or anything else) according this variable? It must be 2, if not the availability is affected....

 

Thank you in advanced.

Hello Diogo,

 

I don't believe ifOperStatus is a pollable MIB OID. We can query it during discovery and updates to see if it changed, but its a static value that we don't support as a pollable OID.

 

I wonder what your goal is here? Curious how you'll use ifOperStatus value 2, which is a down interface, to provide Availability?

 

I would assume any interface set to ifOperStatus=2 isn't going to be Available.

 

Thanks,

Mike

The goal is to measure the availability of a "Wireless Interface" aka Cisco AP. So, polling the OperStatus or AdminStatus I could get this metric.

I am searching and I found something. Can I use something like below?

 

<Expression destAttr="AdminStatus"><![CDATA[
if ( (isdef bsnAPAdminStatus) && (bsnAPAdminStatus==1) ) {
return 100;
}
else {
return 0;
}
]]>
</Expression>

Take a look at IfTableMib, it is doing something like this already - Availability is set to 100% when ifOperStatus = 1. There are three destAttrs to look at: OperStatus, OperStatusPollable, and Availability. There are two status attributes for historical reasons; OperStatus is used for discovery & filtering, OperStatusPollable is a polled metric you can report on.

 

 

Here are the expressions from IfTableMib:

 

<Expression destAttr="OperStatus">ifOperStatus</Expression>

<Expression destAttr="AdminStatus">ifAdminStatus</Expression>

<Expression destAttr="OperStatusPollable">ifOperStatus</Expression>

<Expression destAttr="AdminStatusPollable">ifAdminStatus</Expression>

<Expression destAttr="Availability">(ifOperStatus == 1) ? 100 : 0</Expression>

 

The expression you found is the same thing, only with an isdef included for safety, and on a different attribute.

Hi Diogo,

 

I was curious if the information Gerald provided above helped with this request. Does this remain unresolved for you?

 

Thanks,

I solved that using the tip above:

<Expression destAttr="Availability">(bsnDot11EssAdminStatus == 1) ? 100 : 0</Expression>

 

But in this case I applied some cases like:

And also for Channel Availability:

<Expression destAttr="Availability">
<![CDATA[
if ( (isdef wlanAPRadioChannel) && (wlanAPRadioChannel>0) ) {
return 100;
}
else {
return 0;
}
]]>
</Expression>

Thanks for the follow up Diogo!!

 

Now if other users search for the same thing hopefully they'll find the answer.
