Ops Agent overview

Stay organized with collections Save and categorize content based on your preferences.

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

You can configure the Ops Agent to support parsing of log files from third-party applications. For more information, see Logging configurations.

To install the Ops Agent, see Installing the Ops Agent.

Ops Agent features

Overall features include:

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.

    • 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 for Java, Python, and Golang.
  • Third-party application support
