# ngx_bumpylife
`ngx_bumpylife` sets the randomized limit of requests to be processed for each worker process.
It is inspired by [`ap-mod_bumpy_life`](https://github.com/hirose31/ap-mod_bumpy_life).
# Status
Early development phase
# Directives
## bumpylife
|Syntax |bumpylife on | off |
|-------|--------------------|
|Default|off |
|Context|http |
Enables or disables `ngx_bumpylife`.
## bumpylife_min
|Syntax |bumpylife number |
|-------|-----------------|
|Default|0 |
|Context|http |
Sets the minimun value for the limit of requests to be processed.
## bumpylife_max
|Syntax |bumpylife number |
|-------|-----------------|
|Default|0 |
|Context|http |
Sets the max value for the limit of requests to be processed.
# Behavior
If `ngx_bumpylife` is enabled, each worker process increments own counter and
sets `ngx_http_bumpylife_target_pid` in shared memory own pid when the number of requests to be processed overs the limit.
Moreover, checks the variable `ngx_http_bumpylife_target_pid` in shared memory and
sends `SIGQUIT` the process which pid is `ngx_http_bumpylife_target_pid`.
The limit of requests to be processed is randomized in the `bumpylife_min` to `bumpylife_max` range.
And `ngx_bumpylife` does not work in the cases below.
* `bumpylife_min` or `bumpylife_max` is zero.
* `bumpylife_min` is higher than `bumpylife_max`.
# Quick Start
```nginx
http {
bumpylife on;
bumpylife_min 500;
bumpylife_max 800;
...
}
```
