on GitHub

This is release v0.32.0-rc.0 of the Grafana Agent.

Upgrading

Read the upgrade guide for specific instructions on upgrading from older versions.

Notable changes:

Breaking changes

• Support for the embedded Flow UI for 32-bit ARMv6 builds is temporarily
  removed.

• Node Exporter configuration options changed to align with new upstream version:

  • diskstats_ignored_devices is now diskstats_device_exclude in agent configuration.
  • ignored_devices is now device_exclude in flow configuration.

• Some blocks in Flow components have been merged with their parent block to make the block hierarchy smaller:

  • discovery.docker > http_client_config is merged into the discovery.docker block.
  • discovery.kubernetes > http_client_config is merged into the discovery.kubernetes block.
  • loki.source.kubernetes > client > http_client_config is merged into the client block.
  • loki.source.podlogs > client > http_client_config is merged into the client block.
  • loki.write > endpoint > http_client_config is merged into the endpoint block.
  • mimir.rules.kubernetes > http_client_config is merged into the mimir.rules.kubernetes block.
  • otelcol.receiver.opencensus > grpc is merged into the otelcol.receiver.opencensus block.
  • otelcol.receiver.zipkin > http is merged into the otelcol.receiver.zipkin block.
  • phlare.scrape > http_client_config is merged into the phlare.scrape block.
  • phlare.write > endpoint > http_client_config is merged into the endpoint block.
  • prometheus.remote_write > endpoint > http_client_config is merged into the endpoint block.
  • prometheus.scrape > http_client_config is merged into the prometheus.scrape block.

• The loki.process component now uses a combined name for stages, simplifying the block hierarchy. For example, the stage > json block hierarchy is now a single block called stage.json. All stage blocks in loki.process have been updated to use this simplified hierarchy.

• remote.s3 client_options block has been renamed to client.

• Renamed prometheus.integration.node_exporter to prometheus.exporter.unix.

• As first announced in v0.30, support for the EXPERIMENTAL_ENABLE_FLOW environment variable has been removed in favor of AGENT_MODE=flow.

Features

• New integrations:

  • oracledb
  • mssql
  • cloudwatch metrics
  • azure
  • gcp

• New Grafana Agent Flow components:

  • loki.echo writes received logs to stdout.
  • loki.source.docker reads logs from Docker containers and forwards them to other loki components.
  • loki.source.kafka reads logs from Kafka events and forwards them to other loki components.
  • loki.source.kubernetes_events watches for Kubernetes Events and converts them into log lines to forward to other loki components. It is the equivalent of the eventhandler integration.
  • otelcol.processor.tail_sampling samples traces based on a set of defined policies from otelcol components before forwarding them to other otelcol components.
  • prometheus.exporter.apache collects metrics from an apache web server
  • prometheus.exporter.consul collects metrics from a consul installation
  • prometheus.exporter.github collects metrics from GitHub
  • prometheus.exporter.process aggregates and collects metrics by scraping /proc.
  • prometheus.exporter.redis collects metrics from a redis database

Installation:

Grafana Agent is currently distributed in plain binary form, Docker container images, a Windows installer, and a Kubernetes install script. Choose whichever fits your use-case best.

Kubernetes

Install directions here.

Docker container:

• https://hub.docker.com/r/grafana/agent

Docker containers are published as grafana/agent:v0.32.0-rc.0. For Windows Docker containers, use grafana/agent:v0.32.0-rc.0-windows instead.

Windows installer

The Windows installer is provided as a release asset for x64 machines.

Binary

We provide precompiled binary executables for the most common operating systems. Choose from the assets below for your matching operating system.

Note: ppc64le builds are currently considered secondary release targets and do not have the same level of support and testing as other platforms.

Example for the linux operating system on amd64:

# download the binary
curl -O -L "https://github.com/grafana/agent/releases/download/v0.32.0-rc.0/grafana-agent-linux-amd64.zip"

# extract the binary
unzip "grafana-agent-linux-amd64.zip"

# make sure it is executable
chmod a+x "grafana-agent-linux-amd64"

agentctl

agentctl, a tool for helping you interact with the Agent, is available as a Docker image:

Docker containers are published as grafana/agentctl:v0.32.0-rc.0. For Windows Docker containers, use grafana/agentctl:v0.32.0-rc.0-windows instead.

Or as a binary. Like before, choose the assets below that matches your operating system. For example, with linux on amd64:

# download the binary
curl -O -L "https://github.com/grafana/agent/releases/download/v0.32.0-rc.0/grafana-agentctl-linux-amd64.zip"

# extract the binary
unzip "grafana-agentctl-linux-amd64.zip"

# make sure it is executable
chmod a+x "grafana-agentctl-linux-amd64"

agent-operator

agent-operator, a Kubernetes Operator for the Grafana Agent, is available only as a Docker image:

docker pull "grafana/agent-operator:v0.32.0-rc.0"
