Observability in Voice Microservices
Contents
Learn about the logs, metrics, and alerts you should monitor for Voice Microservices.
Monitoring
Private edition services expose metrics that can be scraped by Prometheus, to support monitoring operations and alerting.
- As described on Monitoring overview and approach, you can use a tool like Grafana to create dashboards that query the Prometheus metrics to visualize operational status.
- As described on Customizing Alertmanager configuration, you can configure Alertmanager to send notifications to notification providers such as PagerDuty, to notify you when an alert is triggered because a metric has exceeded a defined threshold.
The services expose a number of Genesys-defined and third-party metrics. The metrics that are defined in third-party software used by private edition services are available for you to use as long as the third-party provider still supports them. For descriptions of available Voice Microservices metrics, see:
- Agent State Service metrics
- Call State Service metrics
- Config Service metrics
- Dial Plan Service metrics
- FrontEnd Service metrics
- ORS metrics
- Voice Registrar Service metrics
- Voice RQ Service metrics
- Voice SIP Cluster Service metrics
- Voice SIP Proxy Service metrics
- Voicemail metrics
See also System metrics.
Deploy dashboard and alert dashboards
Deploy dashboards and alert rules using these Helm charts:
- voice-dashboards – This installs the dashboards that are created to monitor various Voice Services.
- voice-alertrules – This installs the alert rules that specify what type of alarm must be triggered based on the metrics.
helm repo add helm-staging https://<jfrog artifactory/helm location> --username "$JFROG_USER" --password "$JFROG_PASSWORD" helm repo update helm install voice-alertrules -n voice https://<jfrog artifactory/helm location>/voice-monitoring/voice-alertrules-1.0.5.tgz --username "$JFROG_USER" --password "$JFROG_PASSWORD" helm install voice-dashboards -n voice https://<jfrog artifactory/helm location>/voice-monitoring/voice-dashboards-1.0.8.tgz --username "$JFROG_USER" --password "$JFROG_PASSWORD"
Enable monitoring
You can expose metrics on a service-by-service basis. To do so, edit the Values.yaml file associated with each service, and enable metrics using either the Prometheus operator, or Prometheus Annotation.
prometheus:
# Enable for Prometheus Annotation
metricServer:
enabled: false
path: /metrics
OR
# Enable for Prometheus operator
podMonitor:
enabled: false
path: /metrics
interval: 30s

---|---|---|---|---|
Agent State Service | PodMonitor | 11000 | http://<pod-ipaddress>:11000/metrics | 30 seconds |
Call State Service | Supports both CRD and annotations | 11900 | http://<pod-ipaddress>:11900/metrics | 30 seconds |
Config Service | Supports both CRD and annotations | 9100 | http://<pod-ipaddress>:9100/metrics | 30 seconds |

FrontEnd Service | Supports both CRD and annotations | 9101 | http://<pod-ipaddress>:9101/metrics | 30 seconds |
ORS | Supports both CRD and annotations | 11200 | http://<pod-ipaddress>:11200/metrics | 30 seconds |
Voice Registrar Service | Supports both CRD and annotations | 11500 | http://<pod-ipaddress>:11500/metrics | 30 seconds |
Voice RQ Service | Supports both CRD and annotations | 12000 | http://<pod-ipaddress>:12000/metrics | 30 seconds |
Voice SIP Cluster Service | Supports both CRD and annotations | 11300 | http://<pod-ipaddress>:11300/metrics | 30 seconds |
Voice SIP Proxy Service | Supports both CRD and annotations | 11400 | http://<pod-ipaddress>:11400/metrics | 30 seconds |
Voicemail | Supports both CRD and annotations | 8081 | http://<pod-ipaddress>:8081/metrics | 30 seconds |
Configure metrics
The metrics that are exposed by the Voice Microservices are available by default. No further configuration is required in order to define or expose these metrics. You cannot define your own custom metrics.
The Metrics pages linked to above show some of the metrics the Voice Microservices expose. You can also query Prometheus directly or via a dashboard to see all the metrics available from the Voice Microservices.
Alerting
Private edition services define a number of alerts based on Prometheus metrics thresholds.
For descriptions of available Voice Microservices alerts, see:
- Agent State Service alerts
- Call State Service alerts
- Config Service alerts
- Dial Plan Service alerts
- FrontEnd Service alerts
- ORS alerts
- Voice Registrar Service alerts
- Voice RQ Service alerts
- Voice SIP Cluster Service alerts
- Voice SIP Proxy Service alerts
- Voicemail alerts
Configure alerts
Private edition services define a number of alerts by default (for Voice Microservices, see the pages linked to above). No further configuration is required.
The alerts are defined as PrometheusRule objects in a prometheus-rule.yaml file in the Helm charts. As described above, Voice Microservices does not support customizing the alerts or defining additional PrometheusRule objects to create alerts based on the service-provided metrics.
Logging
Voice Microservices can write logs generated by internal components to the following locations:
- Persistent Volume/Persistent Volume Claim with RWX storage. For more information, see Log volume, Deploy the Voice Services, and Persistent volumes.
- Ephemeral volume (emptyDir) with a Fluent Bit logging sidecar that tails log files and sends them to standard output (stdout). For more information, see Forwarding logs to stdout.
Forwarding logs to stdout
You can optionally forward logs from internal components to stdout using a logging sidecar (Genesys currently supports Fluent Bit) and an ephemeral volume (emptyDir). The Fluent Bit sidecar tails the logs and sends them to stdout. For more information, see Sidecar processed logging in the Genesys Multicloud CX Private Edition Operations guide.
The SIPNode logs within the SIP Cluster service can be forwarded to stdout. By default, forwarding logs to stdout is disabled. To enable the log forwarding option, set the following parameters in the voice-sip Helm Chart values.yaml file:
volumes:
# Mount an Ephemeral Volume for storing the legacy SIPS logs.
sipsLog:
mountPath: "/opt/genesys/logs/sip_node/SIPS"
sipsLoggingSidecar:
enabled: true # sips-logging-sidecar container will be created
image:
registry: genesysengagedev.azurecr.io # Registry from where the images will be fetched
repository: sre/fluent-bit # repository and folder where the particular service image is located
pullPolicy: Always # Policy to pull always or only when the image is not there
tag: 1.8.x # fluent-bit version that will be used by the logging sidecar
context:
create: true #Create configmap for sips-logging-sidecar.Set to true in Values.yaml and set to false in canary_values.yaml
