# STRESS
|
||||
|
||||
Stress test tool for TDengine. It run a set of test cases randomly and show statistics.
|
||||
|
||||
## COMMAND LINE
|
||||
|
||||
``` bash
|
||||
$ ./stress [-h=<localhost>] [-P=<0>] [-d=<test>] [-u=<root>] [-p=<taosdata>] [-c=<4>] [-f=<true>] [-l=<logPath>] [path_or_sql]
|
||||
```
|
||||
|
||||
* **-h**: host name or IP address of TDengine server (default: localhost).
|
||||
* **-P**: port number of TDengine server (default: 0).
|
||||
* **-u**: user name (default: root).
|
||||
* **-p**: password (default: taosdata).
|
||||
* **-c**: concurrency, number of concurrent goroutines for query (default: 4).
|
||||
* **-f**: fetch data or not (default: true).
|
||||
* **-l**: log file path (default: no log).
|
||||
* **path_or_sql**: a SQL statement or path of a JSON file which contains the test cases (default: cases.json).
|
||||
|
||||
## TEST CASE FILE
|
||||
|
||||
```json
|
||||
[{
|
||||
"weight": 1,
|
||||
"sql": "select * from meters where ts>=now+%dm and ts<=now-%dm and c1=%v and c2=%d and c3='%s' and tbname='%s'",
|
||||
"args": [{
|
||||
"type": "range",
|
||||
"min": 30,
|
||||
"max": 60
|
||||
}, {
|
||||
"type": "bool"
|
||||
}, {
|
||||
"type": "int",
|
||||
"min": -10,
|
||||
"max": 20
|
||||
}, {
|
||||
"type": "string",
|
||||
"min": 0,
|
||||
"max": 10,
|
||||
}, {
|
||||
"type": "list",
|
||||
"list": [
|
||||
"table1",
|
||||
"table2",
|
||||
"table3",
|
||||
"table4"
|
||||
]
|
||||
}]
|
||||
}]
|
||||
```
|
||||
|
||||
The test case file is a standard JSON file which contains an array of test cases. For test cases, field `sql` is mandatory, and it can optionally include a `weight` field and an `args` field which is an array of arguments.
|
||||
|
||||
`sql` is a SQL statement, it can include zero or more arguments (placeholders).
|
||||
|
||||
`weight` defines the possibility of the case being selected, the greater value the higher possibility. It must be an non-negative integer and the default value is zero, but, if all cases have a zero weight, all the weights are regarded as 1.
|
||||
|
||||
Placeholders of `sql` are replaced by arguments in `args` at runtime. There are 5 types of arguments currently:
|
||||
|
||||
* **bool**: generate a `boolean` value randomly.
|
||||
* **int**: generate an `integer` between [`min`, `max`] randomly, the default value of `min` is 0 and `max` is 100.
|
||||
* **range**: generate two `integer`s between [`min`, `max`] randomly, the first is less than the second, the default value of `min` is 0 and `max` is 100.
|
||||
* **string**: generate a `string` with length between [`min`, `max`] randomly, the default value of `min` is 0 and `max` is 100.
|
||||
* **list**: select an item from `list` randomly.
|
||||
|
||||
## OUTPUT
