Ops Agent overview

The Ops Agent is the primary agent for collecting telemetry from your Compute Engine instances. Combining the collection of logs, metrics, and traces into a single process, the Ops Agent uses Fluent Bit for logs, which supports high-throughput logging, and the OpenTelemetry Collector for metrics and traces.

For information about installing the Ops Agent, see the following:

• For Compute Engine instances, see Installing the Ops Agent.
• For Bare Metal Solution servers, see Set up Ops Agent for Bare Metal Solution.

Ops Agent features

Overall features include:

• Single download and installation/upgrade process.
• Simple, unified, YAML-based configuration.
• Support for standard Linux and Windows distros.
• Proxy support.

Logging features

Logging features include:

• Improved performance compared to the legacy Logging Agent:

  • High throughput capability, taking full advantage of multi-core architecture.
  • Efficient resource (e.g. memory, CPU) management.

• Collecting logs from various sources:

  • Standard system logs (/var/log/syslog and /var/log/messages for Linux, Windows Event Log) collected with no configuration.
  • File-based logs with customizable paths and refresh interval.
  • Journald daemon / systemd logs.
  • Logs over TCP protocol.
  • Logs over Forward protocol (used by Fluent Bit and Fluentd).

• Flexible processing:

  • Parse text logs into structured logs: JSON-based and regular-expression-based parsing.
  • Modify log entries by removing, renaming, or setting fields.
  • Exclude logs based on labels and regular expressions.
  • Detect and concatenate multiline language-exception logs from Java, Python, and Golang.

• Third-party application support

  • Curated third-party application log integration that recognizes common app log file paths and formats.

Monitoring features

Monitoring features include:

• System metrics collected with no configuration. Metrics collected include:
  • cpu metrics
  • disk metrics
  • iis metrics (Windows only)
  • interface metrics
  • gpu metrics (Linux only)
  • memory metrics
  • mssql metrics (Windows only)
  • pagefile metrics (Windows only)
  • swap metrics
  • network metrics
  • processes metrics
  • agent self metrics:
• Third-party application support
  • Curated integrations for third-party application metrics, which collect common app metrics and offer sample dashboards and alert policies.

• Collection of Prometheus metrics from applications running on Compute Engine.
• Collection of OpenTelemetry Protocol (OTLP) metrics and traces from applications instrumented with OpenTelemetry SDKs.
• Collection of NVIDIA Data Center GPU Manager (DCGM) metrics.

Note: Some metrics are only available on VMs running on Linux. See detailed metrics definition and whether they are Linux only in the agent metrics page.

The Cloud Monitoring Metrics Management page provides information that can help you control the amount you spend on billable metrics without affecting observability. The Metrics Management page reports the following information:

• Ingestion volumes for both byte- and sample-based billing, across metric domains and for individual metrics.
• Data about labels and cardinality of metrics.
• Number of reads for each metric.
• Use of metrics in alerting policies and custom dashboards.
• Rate of metric-write errors.

You can also use the Metrics Management to exclude unneeded metrics, eliminating the cost of ingesting them. For more information about the Metrics Management page, see View and manage metric usage.

Trace features

Trace features include:

• Collection of OpenTelemetry Protocol (OTLP) traces from applications instrumented with OpenTelemetry SDKs.

Virtual machine instances

You can install the Ops Agent on Compute Engine instances. To create a Compute Engine instance, see the Compute Engine getting started guide.

Note: The Ops Agent is not supported on Amazon Elastic Compute Cloud (Amazon EC2) instances or on-premises machines.

The following types of VM instances belong to managed services that implement service-specific Monitoring support. Don't try to manually install or configure the Ops Agent on them:

• App Engine standard has built-in Monitoring support. Agents aren't needed.
• App Engine flexible environment instances have pre-installed agents with service-specific configurations.
• Dataflow instances have pre-installed legacy Monitoring agents with service-specific configurations.

• Dataproc instances prior to image version 2.2 have pre-installed legacy Monitoring agents with service-specific configurations.

  You can install the Ops Agent on Dataproc clusters that use image version 2.2 and later to collect syslog logs and host metrics. For more information, see Dataproc 2.2.x release versions.

• Google Kubernetes Engine node instances:
  • GKE on Google Cloud clusters are configured to collect logs and metrics with Logging and Monitoring by default. You can also configure metric and log collection for existing container clusters. For information, see Configuring logging and monitoring for GKE.
  • Google Distributed Cloud instances have an integrated logging and monitoring solution that collects status about system components. For information, see Logging and monitoring.
