How to Filter Cisco ACI Faults by fault code from VNA

Products

• CA Virtual Network Assurance
• DX NetOps

Issue/Introduction

Excessive amounts of Cisco ACI faults were causing performance issues with VNA and the Spectrum Integration. 

Environment

Release : 22.2.x

Component : Virtual Network Assurance For CA Spectrum

Resolution

The $VNA/plugins/ACI Plugin/config/aci-fault-config.xml file can be configured to filter out fault codes. Modify the out of the box aci-fault-config.xml file to add a comma seperated list of fault codes you want filtered out in the file like the following:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<aci-fault-config>

    <fault-patterns>
        <regex>.*fv-\[(.+?)].*</regex>
        <regex>.*tnlp-\[(.+?)].*</regex>
        <regex>.*instp-\[(.+?)].*</regex>
        <regex>.*vns-\[(.+?)].*</regex>
        <regex>.*inb-\[(.+?)].*</regex>
        <regex>.*oob-\[(.+?)].*</regex>
        <regex>.*rtd-\[(.+?)].*</regex>
        <regex>.*br-\[(.+?)].*</regex>
        <regex>.*ra-\[(.+?)].*</regex>
        <regex>.*client-\[(.+?)].*</regex>
        <regex>.*jobs-\[(uni\/.+?)\/</regex>
    </fault-patterns>

    <!-- Filter fault types, codes and severities can be configured using comma separated value-->
    <filter enabled="true">
        <fault-types></fault-types>
        <fault-codes>5032,532,F0411,F105504,F104856</fault-codes>
        <fault-severities></fault-severities>
    </filter>

</aci-fault-config>

Restart the wildfly process and VNA will filter out new faults listed in the aci-fault-config.xml file.
