Scalable protocol-agnostic load testing library for `Go`
## Goals
- Easy to reuse any custom client `Go` code
- Easy to grasp
- Have a slim codebase (500-1k loc)
- No test harness or CLI, easy to integrate and run with plain `go test`
- Have a predictable performance footprint
- Easy to create synthetic or user-based scenarios
- Scalable in `k8s` without complicated configuration or vendored UI interfaces
- Non-opinionated reporting, push any data to `Loki`
## Setup
We are using `nix` for deps, see [installation](https://nixos.org/manual/nix/stable/installation/installation.html) guide
```bash
nix develop
```
## Run example tests with Grafana + Loki
```bash
make start
```
Insert `GRAFANA_TOKEN` created in previous command
```bash
export LOKI_TOKEN=
export LOKI_URL=http://localhost:3030/loki/api/v1/push
export GRAFANA_URL=http://localhost:3000
export GRAFANA_TOKEN=
export DATA_SOURCE_NAME=Loki
export DASHBOARD_FOLDER=LoadTests
export DASHBOARD_NAME=Wasp
make dashboard
```
Run some tests:
```
make test_loki
```
Open your [Grafana dashboard](http://localhost:3000/d/wasp/wasp-load-generator?orgId=1&refresh=5s)
In case you deploy to your own Grafana check `DASHBOARD_FOLDER` and `DASHBOARD_NAME`, defaults are `LoadTests` dir and dashboard is called `Wasp`
Remove environment:
```bash
make stop
```
## Test Layout and examples
Check [examples](examples/README.md) to understand what is the easiest way to structure your tests, run them both locally and remotely, at scale, inside `k8s`
## Run pyroscope test
```
make pyro_start
make test_pyro_rps
make test_pyro_vu
make pyro_stop
```
Open [pyroscope](http://localhost:4040/)
You can also use `trace.out` in the root folder with `Go` default tracing UI
## How it works
Check this [doc](./HOW_IT_WORKS.md) for more examples and project overview
## Loki debug
You can check all the messages the tool sends with env var `WASP_LOG_LEVEL=trace`
If Loki client fail to deliver a batch test will proceed, if you experience Loki issues, consider setting `Timeout` in `LokiConfig` or set `MaxErrors: 10` to return an error after N Loki errors
`MaxErrors: -1` can be used to ignore all the errors
Default Promtail settings are:
```
&LokiConfig{
TenantID: os.Getenv("LOKI_TENANT_ID"),
URL: os.Getenv("LOKI_URL"),
Token: os.Getenv("LOKI_TOKEN"),
BasicAuth: os.Getenv("LOKI_BASIC_AUTH"),
MaxErrors: 10,
BatchWait: 5 * time.Second,
BatchSize: 500 * 1024,
Timeout: 20 * time.Second,
DropRateLimitedBatches: false,
ExposePrometheusMetrics: false,
MaxStreams: 600,
MaxLineSize: 999999,
MaxLineSizeTruncate: false,
}
```
If you see errors like
```
ERR Malformed promtail log message, skipping Line=["level",{},"component","client","host","...","msg","batch add err","tenant","","error",{}]
```
Try to increase `MaxStreams` even more or check your `Loki` configuration
## WASP Dashboard
Basic [dashboard](dashboard/dashboard.go):
### Reusing Dashboard Components
You can integrate components from the WASP dashboard into your custom dashboards.
Example:
```
import (
waspdashboard "github.com/smartcontractkit/wasp/dashboard"
)
func BuildCustomLoadTestDashboard(dashboardName string) (dashboard.Builder, error) {
// Custom key,value used to query for panels
panelQuery := map[string]string{
"branch": `=~"${branch:pipe}"`,
"commit": `=~"${commit:pipe}"`,
"network_type": `="testnet"`,
}
return dashboard.New(
dashboardName,
waspdashboard.WASPLoadStatsRow("Loki", panelQuery),
waspdashboard.WASPDebugDataRow("Loki", panelQuery, true),
# other options
)
}
```
## Annotate Dashboards and Monitor Alerts
To enable dashboard annotations and alert monitoring, utilize the `WithGrafana()` function in conjunction with `wasp.Profile`. This approach allows for the integration of dashboard annotations and the evaluation of dashboard alerts.
Example:
```
_, err = wasp.NewProfile().
WithGrafana(grafanaOpts).
Add(wasp.NewGenerator(getLatestReportByTimestampCfg)).
Run(true)
require.NoError(t, err)
```
Where:
```
type GrafanaOpts struct {
GrafanaURL string `toml:"grafana_url"`
GrafanaToken string `toml:"grafana_token_secret"`
WaitBeforeAlertCheck time.Duration `toml:"grafana_wait_before_alert_check"` // Cooldown period to wait before checking for alerts
AnnotateDashboardUIDs []string `toml:"grafana_annotate_dashboard_uids"` // Grafana dashboardUIDs to annotate start and end of the run
CheckDashboardAlertsAfterRun []string `toml:"grafana_check_alerts_after_run_on_dashboard_uids"` // Grafana dashboardIds to check for alerts after run
}
```
