Input and output integration overview
The Consul Input Plugin collects health check metrics from a Consul server, allowing users to monitor service statuses effectively.
This plugin enables Telegraf to send metrics to Cortex using the Prometheus remote write protocol, allowing seamless ingestion into Cortex’s scalable, multi-tenant time series storage.
Integration details
Consul
The Consul Input Plugin is designed to gather health check statuses from all services registered with Consul, a tool for service discovery and infrastructure management. By querying the Consul API, this plugin helps users monitor the health of their services and ensure that they are operational and meeting service level agreements. It does not provide telemetry data, but users can utilize StatsD if they want to collect those metrics. The plugin offers configuration options to connect to the Consul server, manage authentication, and specify how to handle tags derived from health checks.
Cortex
With Telegraf’s HTTP output plugin and the prometheusremotewrite
data format you can send metrics directly to Cortex, a horizontally scalable, long-term storage backend for Prometheus. Cortex supports multi-tenancy and accepts remote write requests using the Prometheus protobuf format. By using Telegraf as the collection agent and Remote Write as the transport mechanism, organizations can extend observability into sources not natively supported by Prometheus—such as Windows hosts, SNMP-enabled devices, or custom application metrics—while leveraging Cortex’s high-availability and long-retention capabilities.
Configuration
Consul
[[inputs.consul]]
## Consul server address
# address = "localhost:8500"
## URI scheme for the Consul server, one of "http", "https"
# scheme = "http"
## Metric version controls the mapping from Consul metrics into
## Telegraf metrics. Version 2 moved all fields with string values
## to tags.
##
## example: metric_version = 1; deprecated in 1.16
## metric_version = 2; recommended version
# metric_version = 1
## ACL token used in every request
# token = ""
## HTTP Basic Authentication username and password.
# username = ""
# password = ""
## Data center to query the health checks from
# datacenter = ""
## Optional TLS Config
# tls_ca = "/etc/telegraf/ca.pem"
# tls_cert = "/etc/telegraf/cert.pem"
# tls_key = "/etc/telegraf/key.pem"
## Use TLS but skip chain & host verification
# insecure_skip_verify = true
## Consul checks' tag splitting
# When tags are formatted like "key:value" with ":" as a delimiter then
# they will be split and reported as proper key:value in Telegraf
# tag_delimiter = ":"
Cortex
[[outputs.http]]
## Cortex Remote Write endpoint
url = "http://cortex.example.com/api/v1/push"
## Use POST to send data
method = "POST"
## Send metrics using Prometheus remote write format
data_format = "prometheusremotewrite"
## Optional HTTP headers for authentication
# [outputs.http.headers]
# X-Scope-OrgID = "your-tenant-id"
# Authorization = "Bearer YOUR_API_TOKEN"
## Optional TLS configuration
# tls_ca = "/path/to/ca.pem"
# tls_cert = "/path/to/cert.pem"
# tls_key = "/path/to/key.pem"
# insecure_skip_verify = false
## Request timeout
timeout = "10s"
Input and output integration examples
Consul
-
Service Health Monitoring Dashboard: Utilize the Consul Input Plugin to create a comprehensive health monitoring dashboard for all services registered with Consul. This allows operations teams to visualize the health status in real time, enabling quick identification of service issues and facilitating rapid responses to service outages or performance degradation.
-
Automated Alerting System: Implement an automated alerting system that uses the health check data gathered by the Consul Input Plugin to trigger notifications whenever a service status changes to critical. This setup can integrate with notification systems like Slack or email, ensuring that team members are alerted immediately to address potential issues.
-
Integration with Incident Management: Leverage the health check data from the Consul Input Plugin to feed into incident management systems. By analyzing the health status trends, teams can prioritize incidents based on the criticality of the affected services and streamline their resolution processes, improving overall service reliability and customer satisfaction.
Cortex
-
Unified Multi-Tenant Monitoring: Use Telegraf to collect metrics from different teams or environments and push them to Cortex with separate
X-Scope-OrgID
headers. This enables isolated data ingestion and querying per tenant, ideal for managed services and platform teams. -
Extending Prometheus Coverage to Edge Devices: Deploy Telegraf on edge or IoT devices to collect system metrics and send them to a centralized Cortex cluster. This approach ensures consistent observability even for environments without local Prometheus scrapers.
-
Global Service Observability with Federated Tenants: Aggregate metrics from global infrastructure by configuring Telegraf agents to push data into regional Cortex clusters, each tagged with tenant identifiers. Cortex handles deduplication and centralized access across regions.
-
Custom App Telemetry Pipeline: Collect app-specific telemetry via Telegraf’s
exec
orhttp
input plugins and forward it to Cortex. This allows DevOps teams to monitor app-specific KPIs in a scalable, query-efficient format while keeping metrics logically grouped by tenant or service.
