5 NRF Alerts

This chapter includes information about the NRF alerts.

The following table describes the various alert levels generated by NRF:

Table 5-1 Alerts Levels or Severity Types

Alerts Levels/Severity Types Definition
Critical Indicates a severe issue that poses a significant risk to safety, security, or operational integrity. It requires immediate response to address the situation and prevent serious consequences. Raised for conditions may affect the service of NRF.
Major Indicates a more significant issue that has an impact on operations or poses a moderate risk. It requires prompt attention and action to mitigate potential escalation. Raised for conditions may affect the service of NRF.
Minor Indicates a situation that is low in severity and does not pose an immediate risk to safety, security, or operations. It requires attention but does not demand urgent action. Raised for conditions may affect the service of NRF.
Info or Warn (Informational) Provides general information or updates that are not related to immediate risks or actions. These alerts are for awareness and do not typically require any specific response. WARN and INFO alerts may not impact the service of NRF.

Note:

  • Summary or dimensions may vary based on deployment.
  • The alert triggering time varies as per the environment in which it is deployed.
  • The performance and capacity of the NRF system may vary based on the call model, Feature or Interface configuration, and underlying CNE and hardware environment.

5.1 System Level Alerts

Severity Critical
Condition When all the NRF services are unavailable, either because the NRF is getting deployed or purged. The NRF services considered are nfregistration, nfsubscription, nrfauditor, nrfconfiguration, nfaccesstoken, nfdiscovery, appinfo, ingressgateway, and egressgateway.
OID 1.3.6.1.4.1.323.5.3.36.1.2.7016
Metric Used

'up'

Note: This is a Prometheus metric used for instance availability monitoring.

If this metric is not available, use a similar metric as exposed by the monitoring system.
Recommended Actions The alert is cleared automatically when the NRF services restart.

Steps:

  1. Check for service-specific alerts which may be causing the issues with service exposure.
  2. Run the following command to check the pod status:
    $ kubectl get po -n <namespace>
    1. Run the following command to analyze the error condition of the pod that is not in the Running state:
      $ kubectl describe pod <pod name not in Running state> -n <namespace>

      Where <pod name not in Running state> indicates the pod that is not in the Running state.

  3. Refer to the application logs on Kibana and check for database related failures such as connectivity and invalid secrets. The logs can be filtered based on the services.
  4. Check for helm status to make sure there are no errors:
    $ helm status <helm release name of the desired NF> -n <namespace>

    If it is not in “STATUS : DEPLOYED”, then capture logs and event again.

  5. In case the issue persists, capture all the outputs for the above steps and contact My Oracle Support.

5.5 NRF Alert Configuration

NRF Alert Configuration

Follow the steps below for NRF Alert configuration in Prometheus:

Note:

  1. The Name is the release name used in helm install command.
  2. The Namespace is the namespace used in helm install command. By default Namespace for NRF is ocnrf that must be update as per the deployment.
  3. The ocnrf-config-1.1.0.0.0.zip file can be downloaded from OHC.

    Unzip the ocnrf-config-1.1.0.0.0.zip package after downloading to get NrfAlertrules.yaml file.

  1. Take Backup of current configuration map of Prometheus: 
    kubectl get configmaps _NAME_-server -o yaml -n _Namespace_ > /tmp/tempConfig.yaml
  2. Check and Add NRF Alert file name inside Prometheus configuration map: 
    sed -i '/etc\/config\/alertsnrf/d' /tmp/tempConfig.yaml
sed -i '/rule_files:/a\  \- /etc/config/alertsnrf' /tmp/tempConfig.yaml
  3. Update configuration map with updated file name of NRF alert file: 
    kubectl replace configmap _NAME_-server -f /tmp/tempConfig.yaml
  4. Add NRF Alert rules in configuration map under file name of NRF alert file: 
    kubectl patch configmap _NAME_-server -n _Namespace_--type merge --patch
"$(cat ~/NrfAlertrules.yaml)"

Note:

Prometheus server takes updated configuration map that is automatically reloaded after 60 seconds approximately. Refresh the Prometheus GUI to confirm that the NRF Alerts are loaded.

5.5.1 Disable Alerts

This section explains the procedure to disable the alerts in NRF.
  1. Edit NrfAlertrules-25.1.202.yaml file to remove a specific alert.
  2. Remove complete content of a specific alert from the NrfAlertrules-25.1.202.yaml file.
    For example: If you want to remove OcnrfTrafficRateAboveMinorThreshold alert, remove the complete content:
    ## ALERT SAMPLE START##

      - alert: OcnrfTrafficRateAboveMinorThreshold
        annotations:
          description: 'Ingress traffic Rate is above minor threshold i.e. 800 mps (current value is: {{ $value }})'
          summary: 'Traffic Rate is above 80 Percent of Max requests per second(1000)'
        expr: sum(rate(oc_ingressgateway_http_requests_total{app_kubernetes_io_name="ingressgateway",kubernetes_namespace="ocnrf"}[2m])) >= 800 < 900
        labels:
          severity: Minor
## ALERT SAMPLE END##
  3. Perform Alert configuration. For more information about configuring alerts, see NRF Alert Configuration section.

5.5.2 Configuring SNMP Notifier

This section describes the procedure to configure SNMP Notifier.

Configure the IP and port of the SNMP trap receiver in the SNMP Notifier using the following procedure:
  1. Run the following command to edit the deployment:
    $ kubectl edit deploy <snmp_notifier_deployment_name> -n <namespace>

    Example:

    $ kubectl edit deploy occne-snmp-notifier -n occne-infra

    SNMP deployment yaml file is displayed.

  2. Edit the SNMP destination in the deployment yaml file as follows:
    --snmp.destination=<destination_ip>:<destination_port>

    Example:

    --snmp.destination=10.75.203.94:162
  3. Save the file.
Checking SNMP Traps
Following is an example on how to capture the logs of the trap receiver server to view the generated SNMP traps:
$ docker logs <trapd_container_id>
Sample output:

          is: 0)
MIB Files for NRF

There are two MIB files which are used to generate the traps. The user need to update these files along with the Alert file in order to fetch the traps in their environment.

  • ocnrf_mib_tc_25.1.202.mib

    This is considered as NRF top level mib file, where the objects and their data types are defined.

  • ocnrf_mib_25.1.202.mib

    This file fetches the objects from the top level mib file and based on the alert notification, these objects can be selected for display.

  • toplevel_25.1.202.mib: This defines the OIDs for all NFs.

Note:

MIB files are packaged along with the release package. Download the file from MOS. For more information on downloading the release package, see Oracle Communications Cloud Native Core, Network Repository Function Installation, Upgrade, and Fault Recovery Guide.
