alert on port link

[cyrill]

Hello.

I've a problem. I just want send an email with thold when a port of a Switch is down !

Why can I set up this threshold ???

thanks for your help

[cyrill]

no idea ??

[Howie]

When traffic=0? Even on a quiet link there are a few bytes of traffic usually.

Other than that, you would need to find something to graph, so that threshold can see it - e.g. ifOperStatus.

[cyrill]

ok. and what's ifOperStatus ? is the status of my ethernet card ? what's return it ?

[Howie]

ok. and what's ifOperStatus ? is the status of my ethernet card ? what's return it ?

It's the SNMP MIB variable that shows if the interface is up, down or disabled. Search on these forums for ifOperStatus.

[cyrill]

hum ! it's very interressant concept ! it's very accurate !!!

And it's possible to use this concept with thold ?

[Howie]

It's a number that you can apply a threshold to. I haven't tried it, but it should work.

[cyrill]

And can I set up a threshold template with this system ? How can I insert it to the Thold ? Must I create a new Data Template ?

[cyrill]

please help me ! how can I get this value ? Must I set a new sample OID ? I just want to say the way that I must take !

[Howie]

YES you need to make a new data template. YES it's a new OID. YES it's in another forum thread already.

[cyrill]

I've search but i don't found...

I've found that I must use the OID .1.3.6.2.1.2.2.1.8 and it's return all status of each interface (1 for up and 2 for down). I've understand that I must use this in a new Simple OID. But I don't understand the next step....

[chrisgapske]

I use this all the time.

So I am basically polling the OID index for interface status.



It is best to ignora MIB data because we don’t want to have it translate
to UP or Down for you .. You want the data to come back as 1 or 2



These are the changed necessary to monitor interface



And if you want you can do a customer CDF





Interface Status..



Update



(Cacti install path)/resource/snmp_queries/interfaces.xml



Make Change



<ifOperStatus

<name>Status</name>

<method>walk</method>

<source>VALUE/REGEXP:[a-zA-Z]{1,}\(([1-9]{1})+\)$</source>

<direction>output</direction>

<oid.1.3.6.1.2.1.2.2.1.8</oid>

</ifOperStatus>







(Cacti install path)/lib/snmp.php



Change



Code:

define("REGEXP_SNMP_TRIM",
"(hex|counter(32|64)|gauge|gauge(32|64)|float|ipaddress|string|integer):");

with this



Code:

define("REGEXP_SNMP_TRIM",
"(hex|counter(32|64)|gauge|gauge(32|64)|float|ipaddress|string|integer):|(up|down)\(|\)$");




After you have made these changes you should be able to graph port status just like you would traffic or any other.


you will get a 1 for up and 2 for down. You can do a CDF to convert the number but I don't know how.

looks like you did not edit your snmp.conf file for cacti.
