# cAdvisor
|
||||
cAdvisor (Container Advisor) provides container users an understanding of the resource usage and performance characteristics of their running containers. It is a running daemon that collects, aggregates, processes, and exports information about running containers. Specifically, for each container it keeps resource isolation parameters, historical resource usage, histograms of complete historical resource usage and network statistics. This data is exported by container and machine-wide.

# Prometheus Node Exporter
|
||||
Prometheus exporter for hardware and OS metrics exposed by *NIX kernels, written in Go with pluggable metric collectors.
|
||||
|
||||
A Dashboard to use with Node Exporter and Grafana can be found [here](https://grafana.com/grafana/dashboards/1860-node-exporter-full/).
|
||||
|
||||
## Usage
|
||||
The node_exporter listens on HTTP port 9100 by default.
|
||||
|
||||
### Docker
|
||||
The `node_exporter` is designed to monitor the host system. Deploying in containers requires extra care in order to avoid monitoring the container itself.
|
||||
|
||||
For situations where containerized deployment is needed, some extra flags must be used to allow the `node_exporter` access to the host namespaces.
|
||||
|
||||
Be aware that any non-root mount points you want to monitor will need to be bind-mounted into the container.
|
||||
|
||||
If you start container for host monitoring, specify `path.rootfs` argument. This argument must match path in bind-mount of host root. The `node_exporter` will use `path.rootfs` as prefix to access host filesystem.
|
||||
|
||||
```yml
|
||||
---
|
||||
version: '3.8'
|
||||
|
||||
services:
|
||||
node_exporter:
|
||||
image: quay.io/prometheus/node-exporter:latest
|
||||
container_name: node_exporter
|
||||
command:
|
||||
- '--path.rootfs=/host'
|
||||
network_mode: host
|
||||
pid: host
|
||||
restart: unless-stopped
|
||||
volumes:
|
||||
- '/:/host:ro,rslave'
|
||||
```
|
||||
|
||||
On some systems, the timex collector requires an additional Docker flag, `--cap-add=SYS_TIME`, in order to access the required syscalls.
|
||||
|
||||
### Prometheus
|
||||
Configure Prometheus to scrape the exposed node exporter:
|
||||
|
||||
```yml
|
||||
global:
|
||||
scrape_interval: 15s
|
||||
|
||||
scrape_configs:
|
||||
- job_name: node
|
||||
static_configs:
|
||||
- targets: ['localhost:9100']
|
||||
```
|
||||
|
||||
## Configuration
|
||||
Node Exporter can be configured using CLI arguments.
|
||||

||||

### Web Configuration
|
||||
Exporters and services instrumented with the Exporter Toolkit share the same web configuration file format. This is experimental and might change in the future.
|
||||
|
||||
To specify which web configuration file to load, use the `--web.config.file` flag.
|
||||
|
||||
Basic config file:
|
||||
```yml
|
||||
# TLS and basic authentication configuration example.
|
||||
#
|
||||
# Additionally, a certificate and a key file are needed.
|
||||
tls_server_config:
|
||||
cert_file: server.crt
|
||||
key_file: server.key
|
||||
|
||||
# Usernames and passwords required to connect.
|
||||
# Passwords are hashed with bcrypt: https://github.com/prometheus/exporter-toolkit/blob/master/docs/web-configuration.md#about-bcrypt.
|
||||
basic_auth_users:
|
||||
alice: $2y$10$mDwo.lAisC94iLAyP81MCesa29IzH37oigHC/42V2pdJlUprsJPze

# Prometheus
|
||||
Prometheus is an open-source systems monitoring and alerting toolkit originally built at SoundCloud.
|
||||
It collects and stores its metrics as time series data, i.e. metrics information is stored with the timestamp at which it was recorded, alongside optional key-value pairs called labels.
|
||||
This data can then be visualized using [Grafana](./Grafana.md).
|
||||
|
||||
## Docker Compose
|
||||
|
||||
```yml
|
||||
services:
|
||||
prometheus:
|
||||
image: prom/prometheus
|
||||
ports:
|
||||
- 9090:9090
|
||||
volumes:
|
||||
- ./data:/prometheus
|
||||
- ./conf:/etc/prometheus
|
||||
```
|
||||
|
||||
## Configuration
|
||||
Basic prometheus config:
|
||||
