Expand description
All metrics optionally collected during a Goose load test.
By default, Goose collects metrics during a load test in a GooseMetrics
object
that is returned by
GooseAttack::execute()
when a load
test finishes.
Example
use goose::prelude::*;
#[tokio::main]
async fn main() -> Result<(), GooseError> {
let goose_metrics: GooseMetrics = GooseAttack::initialize()?
.register_scenario(scenario!("ExampleUsers")
.register_transaction(transaction!(example_transaction))
)
// Set a default host so the load test will start.
.set_default(GooseDefault::Host, "http://localhost/")?
// Set a default run time so this test runs to completion.
.set_default(GooseDefault::RunTime, 1)?
.execute()
.await?;
// It is now possible to do something with the metrics collected by Goose.
// For now, we'll just pretty-print the entire object.
println!("{:#?}", goose_metrics);
/**
// For example:
$ cargo run -- -H http://example.com -u1 -t1

Fields§
§hash: u64
A hash of the load test, primarily used to validate all Workers in a Gaggle are running the same load test.
history: Vec<TestPlanHistory>
A vector recording the history of each load test step.
duration: usize
Total number of seconds the load test ran.
maximum_users: usize
Maximum number of users simulated during this load test.
This value may be smaller than what was configured at start time if the test didn’t run long enough for all configured users to start.
total_users: usize
Total number of users simulated during this load test.
requests: GooseRequestMetrics
Tracks details about each request made during the load test.
Can be disabled with the --no-metrics
run-time option, or with
GooseDefault::NoMetrics.
transactions: TransactionMetrics
Transactions details about each transaction that is invoked during the load test.
Can be disabled with either the --no-transaction-metrics
or --no-metrics
run-time options,
or with either the
GooseDefault::NoTransactionMetrics or
GooseDefault::NoMetrics.
scenarios: ScenarioMetrics
Transactions details about each scenario that is invoked during the load test.
Can be disabled with either the --no-scenario-metrics
or --no-metrics
run-time options,
or with either the
GooseDefault::NoTransactionMetrics or
GooseDefault::NoMetrics.
errors: GooseErrorMetrics
Tracks and counts each time an error is detected during the load test.
Can be disabled with either the --no-error-summary
or --no-metrics
run-time options,
or with either the
GooseDefault::NoErrorSummary or
GooseDefault::NoMetrics.
hosts: HashSet<String>
Tracks all hosts that the load test is run against.
