Falco Metrics

Leverage continuous metrics for valuable insights into Falco's performance

To explore the metrics functionality, refer to the falco.yaml config file and read the advanced Falco logging, alerting, and metrics sections (e.g. metrics).

Read Prometheus Support to learn how to consume metrics via Prometheus.

The following are all the metrics config options available in the falco.yaml config file:

metrics:
  enabled: true
  interval: 15m
  output_rule: true
  rules_counters_enabled: true
  resource_utilization_enabled: true
  state_counters_enabled: true
  kernel_event_counters_enabled: true
  libbpf_stats_enabled: true
  plugins_metrics_enabled: true
  convert_memory_to_mb: true
  include_empty_values: true

Here is a brief glossary of the currently supported metrics for both the json rule format and Prometheus:

Prometheus Support

Since version 0.38.0, you can also use Falco's web server to expose Falco's metrics. A new /metrics endpoint has been added which provides metrics information that can be collected by Prometheus.

In order to activate this endpoint, three configuration elements must be set in the falco.yaml:

Metrics must be enabled, along with the specific metrics sub-categories you wish to consume (see above).

metrics:
  enabled: true
  ...

The web server must be enabled
The Prometheus metrics endpoint must be enabled

webserver:
  enabled: true
  prometheus_metrics_enabled: true

This endpoint will allow observation of the internal state of Falco providing the same data as configured for the metrics outputs. It will be served on the same port as the health endpoint.

Limitations and Additional Information

Expand the example outputs dropdowns above (for both JSON and Prometheus formats) to explore all supported metrics fields, including their naming conventions and units.

The Prometheus text format documentation can be found here.

The OpenMetrics specification can be found here.

The num_evts wrapper / base field is currently not available for Prometheus metrics; otherwise, there is 1:1 support across all output channels.

However, following the Prometheus recommendations, there might be some slight differences with regard to some metrics fields. Typically calculated fields will not be returned as Prometheus provides the facilities to compute them as part of their queries (e.g. event or drop rates can be calculated in Prometheus).

Plugins Metrics

Since version 0.38.1, Falco allows plugins to provide their own set of custom metrics.

In order to enable plugins metrics, the following configuration elements must be set in the falco.yaml:

metrics:
  enabled: true
  ...
  plugins_metrics_enabled: true
  ...

Please note that this doesn't provide default metrics about the plugin itself, and it will show metrics only if the plugin is providing them.

Currently, none of the officially maintained plugins provides any metric, but this will change in the future.

Lastly, please note that as of Falco 0.38.1, it is not possible to fully use the remaining metrics feature when running plugins without the syscalls source. This is due to some regressions that prevent us from serving a small subset of metrics in this scenario. Near-term improvements in this regard are tracked in the following issue. Please also keep in mind that many of the metrics categories are specific to the syscalls source, such as libbpf_stats_enabled, kernel_event_counters_enabled, or state_counters_enabled.

Breaking Changes

Several metric output field names have changed in Falco 0.38.0 compared to previous releases when using the output_rule or output_file metrics options.

To ensure long-term consistency and validity, we have renamed the following metric output fields. The unit suffix depends on whether you use convert_memory_to_mb: true or not:

falco.hostname -> evt.hostname to be consistent with the newer evt.hostname filter field
cpu_usage_perc_total_host -> host_cpu_usage_perc
memory_used_host -> host_memory_used_kb (or host_memory_used_mb)
procs_running_host -> host_procs_running
open_fds_host -> host_open_fds
memory_rss -> memory_rss_kb (or memory_rss_mb)
memory_pss -> memory_pss_kb (or memory_pss_mb)
memory_vsz -> memory_vsz_kb (or memory_vsz_mb)
container_memory_used -> container_memory_used_bytes (or container_memory_used_mb)
