[stickynotes]

I am a total newbie with zabbix and I am given this task to monitor crc errors can someone please tell me the process that I should follow.I don't even know the basics for CRC monitoring. I will be thankful for your kind help. Please Please Please help!

Googling for "crc error" gave me "About 846,000 results (0.25 seconds)"

What do you mean when you tell us about CRC error?
It is the error on Network Interface? Where is that Interface - on server?on network device?

Or do you want to check CRC error of transferred files to be sure that files was delivered correctly?

Please, give us more information.

Thank you!

Thanks for replying,

The problem set is :
"when the show interface command is given, if there is any CRC errors in the network interface output an alert should be generated."

If CRC errors are increasing continuously. It means the interface is faulty and not processing the traffic correctly.This is what i have to check.

Even I don't know too much about it.
I will be thankful for any help you could do on this.

Google was so friendly today and bring me a lot of links.
One citation

CRC errors can be obtained with locIfInCRC in the OLD-CISCO-INTERFACES-MIB (OID 1.3.6.1.4.1.9.2.2.1.1.12)

locIfInCRC OBJECT-TYPE
                   SYNTAX  INTEGER
                   ACCESS  read-only
                   STATUS  mandatory
                   DESCRIPTION
                           "Number of input packets which had cyclic
                           redundancy checksum errors."
                   ::= { lifEntry 12 }

So, you can:
1) add one more "Item Prototype" into Discovery Rule from "Template SNMP Interfaces"

Name: CRC Error on interface $1
Type: SNMPv2 agent
Key: ifCRCErrors[{#SNMPVALUE}]
SNMP OID: 1.3.6.1.4.1.9.2.2.1.1.12.{#SNMPINDEX}

2) Also, you can create a Trigger Prototype to control CRC increasing

Name: CRC Errors own my CISCO  interface {#SNMPVALUE}!!! (Panic! Run Away!!! Call Superman!!!!)
Expression: {Template SNMP Interfaces:ifCRCErrors[{#SNMPVALUE}].diff(0)}>1
.....
Severity: DISASTER

3) Then you can add "Template SNMP Interfaces" to your Cisco Host. After discovering will done, it creates as many Items "CRC Error on interface ...." and Triggers "CRC Errors...", as many interfaces you have.

it is sufficient detail?
