Monitoring Integrations

Cube Cloud allows exporting logs and metrics to external monitoring tools so you can leverage your existing monitoring stack and retain logs and metrics for the long term.

Under the hood, Cube Cloud uses Vector (opens in a new tab), an open-source tool for collecting and delivering monitoring data. It supports a wide range of destinations (opens in a new tab), also known as sinks.

Guides

Monitoring integrations work with various popular monitoring tools. Check the following guides and configuration examples to get tool-specific instructions:

Amazon CloudWatch

Amazon S3

Datadog

Grafana Cloud

New Relic

Configuration

To enable monitoring integrations, navigate to Settings → Monitoring Integrations and click Enable Vector to add a Vector agent to your deployment. You can use the dropdown to select a Monitoring Integrations tier.

Under Metrics export, you will see credentials for the prometheus_exporter sink, in case you'd like to setup metrics export.

Additionally, create a vector.toml configuration file (opens in a new tab) next to your cube.js file. This file is used to keep sinks configuration. You have to commit this file to the main branch of your deployment for Vector configuration to take effect.

Environment variables

You can use environment variables prefixed with CUBE_CLOUD_MONITORING_ to reference configuration parameters securely in the vector.toml file.

Example configuration for exporting logs to Datadog (opens in a new tab):

[sinks.datadog]
type = "datadog_logs"
default_api_key = "$CUBE_CLOUD_MONITORING_DATADOG_API_KEY"

Inputs for logs

Sinks accept the inputs option that allows to specify which components of a Cube Cloud deployment should export their logs. Supported inputs:

• cubejs-server
• refresh-scheduler
• ext-db
• warmup-job
• cubestore

Example configuration for exporting logs to Datadog (opens in a new tab):

[sinks.datadog]
type = "datadog_logs"
inputs = [
  "cubejs-server",
  "refresh-scheduler",
  "ext-db",
  "warmup-job",
  "cubestore"
]
default_api_key = "da8850ce554b4f03ac50537612e48fb1"
compression = "gzip"

When exporting Cube Store logs using the cubestore input, you can filter logs by providing an array of their severity levels via the levels option. If not specified, only error and info logs will be exported.

Sinks for logs

You can use a wide range of destinations (opens in a new tab) for logs, including the following ones:

• AWS Cloudwatch (opens in a new tab)
• AWS S3 (opens in a new tab), Google Cloud Storage (opens in a new tab), and Azure Blob Storage (opens in a new tab)
• Datadog (opens in a new tab)

Example configuration for exporting all logs, including all Cube Store logs to Azure Blob Storage (opens in a new tab):

[sinks.azure]
type = "azure_blob"
container_name = "my-logs"
connection_string = "DefaultEndpointsProtocol=https;AccountName=mylogstorage;AccountKey=storageaccountkeybase64encoded;EndpointSuffix=core.windows.net"
inputs = [
  "cubejs-server",
  "refresh-scheduler",
  "ext-db",
  "warmup-job",
  "cubestore"
]
 
[sinks.azure.cubestore]
levels = [
  "trace",
  "info",
  "debug",
  "error"
]

Inputs for metrics

Metrics are exported using the metrics input. You can filter them by providing an array of metric names via the list option.

You can further filter exported metrics by providing an array of inputs that applies to metics only.

Example configuration for exporting all metrics from cubejs-server to Prometheus (opens in a new tab) using the prometheus_remote_write sink:

[sinks.prometheus]
type = "prometheus_remote_write"
inputs = [
  "metrics"
]
endpoint = "https://prometheus.example.com:8087/api/v1/write"
 
[sinks.prometheus.auth]
# Strategy, credentials, etc.
 
[sinks.prometheus.metrics]
list = [
  "cpu",
  "memory",
  "requests-count",
  "requests-errors-count",
  "requests-success-count",
  "requests-duration"
]
inputs = [
  "cubejs-server"
]

Sinks for metrics

Metrics are exported in the Prometheus format which is compatible with the following sinks:

• prometheus_exporter (opens in a new tab) (native to Prometheus (opens in a new tab), compatible with Mimir (opens in a new tab))
• prometheus_remote_write (opens in a new tab) (compatible with Grafana Cloud (opens in a new tab))

Example configuration for exporting all metrics from cubejs-server to Prometheus (opens in a new tab) using the prometheus_exporter sink:

[sinks.prometheus]
type = "prometheus_exporter"
inputs = [
  "metrics"
]
 
[sinks.prometheus.metrics]
list = [
  "cpu",
  "memory",
  "requests-count",
  "requests-errors-count",
  "requests-success-count",
  "requests-duration"
]
inputs = [
  "cubejs-server"
]

Navigate to Settings → Monitoring Integrations to take the credentials prometheus_exporter under Metrics export:

You can also customize the user name and password for prometheus_exporter by setting CUBE_CLOUD_MONITORING_METRICS_USER and CUBE_CLOUD_MONITORING_METRICS_PASSWORD environment variables, respectively.
