Issue/Introduction

The QoS ClassMap Metric Family (Cisco CBQos ClassMap (HC) vendor cert) does not discover new classmap items:

Discovery logging shows the following:

DA started the MF discovery at 2023-11-29T20:59:39:
 
DEBUG | 36954305-1292344 | 2023-11-29T20:59:39,345 | nagedDeviceResourceDiscoveryImpl | nagedDeviceResourceDiscoveryImpl 370 | .im.aggregator.discovery |    | startDiscovery on items [12445] for MFs [{http://im.ca.com/normalizer}NormalizedQosClassMapInfo]
 
Then:
 
The DC started to read all the MIB data at 20:59:50.488
 
Nov 29 20:59:50.488: Performing on demand read request = SnmpGetRequest [id=a22d7047-1d48-41a5-a339-b89055e026c0, internetAddress=<insert ip address>, hostname=ujeeptm040.eur.dcn.disn.mil,
varbinds=[source=1.3.6.1.4.1.9.9.166.1.6.1.1.1, ...
 
The last message of DC Debug discovery log is:
 
Nov 29 21:17:35.840: Performing on demand read request = SnmpGetRequest [id=3aaca31f-62d8-4b0c-be4b-ae665fd3d8c9, internetAddress=<insert ip address>, hostname=null,
varbinds=[source=1.3.6.1.4.1.9.9.166.1.5.1.1.4.850228289.1259080928
which is not the reading complete message.
 
 
But in DA, after 15 minutes waiting, it started to generate this message:
 
DEBUG | sk-thread-138785 | 2023-11-29T21:15:10,274 | RawAttributeReadListener | er.impl.RawAttributeReadListener  76 | .im.aggregator.discovery |    | Raw attr read results: Item ID=12445, error=PARTIAL_FAILURE

Cause

Inefficiencies in discovery cause a timeout

Resolution

  1. Create the file /opt/IMDataAggregator/apache-karaf/etc/com.ca.im.item.impl.distributed.DistributedItemRepositoryConfig.cfg
  2. Add the following line:
    messengerTimeoutPerFacetOverride={http://im.ca.com/certifications/snmp}CiscoQosClassMapCounter64Mib=3600
  3. Restart the DA. This will override the timeout settings for each Facet (Vendor Cert) as specified.
