Telemetry
This component provides the following metrics that can be retrieved through
the internal_metrics
source. See the
metrics section in the
monitoring page for more info.
- counter
processing_errors_total
The total number of processing errors encountered by this component. This metric includes the following tags:
component_kind
- The Vector component kind.component_name
- The Vector component ID.component_type
- The Vector component type.error_type
- The type of the errorinstance
- The Vector instance identified by host and port.job
- The name of the job producing Vector metrics.
- counter
processed_events_total
The total number of events processed by this component. This metric includes the following tags:
component_kind
- The Vector component kind.component_name
- The Vector component ID.component_type
- The Vector component type.file
- The file that produced the errorinstance
- The Vector instance identified by host and port.job
- The name of the job producing Vector metrics.
- counter
processed_bytes_total
The total number of bytes processed by the component. This metric includes the following tags:
component_kind
- The Vector component kind.component_name
- The Vector component ID.component_type
- The Vector component type.instance
- The Vector instance identified by host and port.job
- The name of the job producing Vector metrics.
How It Works
Health checks
Health checks ensure that the downstream service is accessible and ready to accept data. This check is performed upon sink initialization. If the health check fails an error will be logged and Vector will proceed to start.
Require health checks
If you'd like to exit immediately upon a health
check failure, you can pass the
--require-healthy
flag:
vector --config /etc/vector/vector.toml --require-healthy
Disable health checks
If you'd like to disable health checks for this
sink you can set the healthcheck
option to
false
.
Transport Layer Security (TLS)
Vector uses Openssl for TLS protocols for it's
maturity. You can enable and adjust TLS behavior via the tls.*
options.
