Noderig collect OS metrics and expose them through a Sensision HTTP endpoint. Each collector is easily configurable, thanks to a simple level cursor
Noderig metrics:
- CPU
- Memory
- Load
- Disk
- Net
- External collectors
Noderig is currently under development. Feel free to comment or contribute!
Noderig is pretty easy to build.
- Clone the repository
- Install glide, follow instructions here https://glide.sh/
- Download dependencies
glide install - Build and run
go run noderig.go
noderig [flags]

--config string config file to use
-l --listen string listen address (default "127.0.0.1:9100")
-v --verbose verbose output

Noderig have some built-in collectors.

Noderig can read a simple default config file.
Configuration is load and override in the following order:
- /etc/noderig/config.yaml
- ~/noderig/config.yaml
- ./config.yaml
- config filepath from command line
Config is composed of three main parts and some config fields:
Noderig have some built-in collectors. They could be configured by a log level. You can also defined custom collectors, in an scollector way. (see: http://bosun.org/scollector/external-collectors)
cpu: 1 # CPU collector level (Optional, default: 1)
mem: 1 # Memory collector level (Optional, default: 1)
load: 1 # Load collector level (Optional, default: 1)
disk: 1 # Disk collector level (Optional, default: 1)
net: 1 # Network collector level (Optional, default: 1)Some collectors have additionals modules.
Add module to <collector>-mods list to enable them.
cpu-mods:
- temperatureSome collectors can accept optional parameters.
net-opts:
interfaces: # Give a filtering list of interfaces for which you want metrics
- eth0
- eth1disk-opts:
names: # Give a filtering list of disks for which you want metrics
- sda1
- sda3Noderig can be customized through some parameters.
period: 1000 # Duration within all the sources should be scraped in ms (Optional, default: 1000)
listen: none # Listen address, set to none to disable http endpoint (Optional, default: 127.0.0.1:9100)
collectors: /opt/noderig # Custom collectors directory (Optional, default: none)1484828198557102// os.cpu{} 2.5202020226869237
