# Monitor Exporter Performance Tests | ||
|
||
In order to run the performance tests, the `azure-devtools` package must be installed. This is done as part of the `dev_requirements`. | ||
Start by creating a new virtual environment for your perf tests. This will need to be a Python 3 environment, preferably >=3.7. | ||
|
||
### Setup for test resources | ||
|
||
These tests will run against a pre-configured Application Insights resource. The following environment variable will need to be set for the tests to access the live resources: | ||
``` | ||
APPLICATIONINSIGHTS_CONNECTION_STRING=<connection string for app insights> | ||
``` | ||
|
||
### Setup for perf test runs | ||
|
||
```cmd | ||
(env) ~/azure-monitor-opentelemetry-exporter> pip install -r dev_requirements.txt | ||
(env) ~/azure-monitor-opentelemetry-exporter> pip install -e . | ||
``` | ||
|
||
## Test commands | ||
|
||
```cmd | ||
(env) ~/azure-monitor-opentelemetry-exporter> cd tests | ||
(env) ~/azure-monitor-opentelemetry-exporter/tests> perfstress | ||
``` | ||
|
||
### Common perf command line options | ||
These options are available for all perf tests: | ||
- `--duration=10` Number of seconds to run as many operations (the "run" function) as possible. Default is 10. | ||
- `--iterations=1` Number of test iterations to run. Default is 1. | ||
- `--parallel=1` Number of tests to run in parallel. Default is 1. | ||
- `--warm-up=5` Number of seconds to spend warming up the connection before measuring begins. Default is 5. | ||
- `--sync` Whether to run the tests in sync or async. Default is False (async). This must be set to True explicitly. | ||
- `--no-cleanup` Whether to keep newly created resources after test run. Default is False (resources will be deleted). | ||
|
||
### MonitorExporter Test options | ||
These options are available for all monitor exporter perf tests: | ||
- `--num-traces` Number of traces to be collected. Defaults to 1. | ||
|
||
### T2 Tests | ||
The tests currently written for the T2 SDK: | ||
- `MonitorExporterPerfTest` Collects sample traces and exports to application insights. | ||
|
||
## Example command | ||
```cmd | ||
(env) ~/azure-monitor-opentelemetry-exporter/tests> perfstress MonitorExporterPerfTest --sync --num-traces=10 | ||
``` |
