# chaosctl | ||
|
||
Chaostl is a tool (currently) used to print debug info. Maintainers would make use of it to better provide their suggestions for issues. | ||
|
||
## How to build | ||
```shell | ||
cd $CHAOSMESH_DIR | ||
make chaosctl | ||
./bin/chaosctl --help #to see if build succeed. | ||
``` | ||
Chaoctl support shell autocompletion, which could save you some typing. Do `./bin/chaosctl completion -h` for detail. | ||
|
||
## How to use | ||
**Debug** | ||
`chaoctl debug` is used to print debug info of certain chaos. Currently, chaosctl support networkchaos, stresschaos and iochaos. | ||
```shell | ||
#to print info of each networkchaos | ||
./bin/chaosctl debug networkchaos | ||
#to print info of certain chaos in default namespace | ||
./bin/chaosctl debug networkchaos CHAOSNAME | ||
#to print info of each networkchaos in certain namespace | ||
./bin/chaosctl debug networkchaos -n NAMESPACE | ||
``` | ||
|
||
**Logs** | ||
`chaoctl log` is used to easily print log from all chaos-mesh components, including controller-manager, chaos-daemon and chaos-dashboard. | ||
```shell | ||
# Default print all log of all chaosmesh components | ||
chaosctl logs | ||
|
||
# to print 100 log lines for chaosmesh components in node NODENAME | ||
chaosctl logs -t 100 -n NODENAME | ||
``` |
