## Features
- [x] Creates & Resolves Incidents
- [x] Posts monitor lag to cachet graphs
- [x] HTTP Checks (body/status code)
- [x] DNS Checks
- [x] Updates Component to Partial Outage
- [x] Updates Component to Major Outage if already in Partial Outage (works with distributed monitors)
- [x] Can be run on multiple servers and geo regions
## Example Configuration
**Note:** configuration can be in json or yaml format. [`example.config.json`](https://github.com/CastawayLabs/cachet-monitor/blob/master/example.config.json), [`example.config.yaml`](https://github.com/CastawayLabs/cachet-monitor/blob/master/example.config.yml) files.

```
## Installation
1. Download binary from [release page](https://github.com/CastawayLabs/cachet-monitor/releases)
2. Create a configuration
3. `cachet-monitor -c /etc/cachet-monitor.yaml`
pro tip: run in background using `nohup cachet-monitor 2>&1 > /var/log/cachet-monitor.log &`
```
Usage:
cachet-monitor (-c PATH | --config PATH) [--log=LOGPATH] [--name=NAME] [--immediate]
cachet-monitor -h | --help | --version
Arguments:
PATH path to config.json
LOGPATH path to log output (defaults to STDOUT)
NAME name of this logger
Examples:
cachet-monitor -c /root/cachet-monitor.json
cachet-monitor -c /root/cachet-monitor.json --log=/var/log/cachet-monitor.log --name="development machine"
Options:
-c PATH.json --config PATH Path to configuration file
-h --help Show this screen.
--version Show version
--immediate Tick immediately (by default waits for first defined interval)
Environment varaibles:
CACHET_API override API url from configuration
CACHET_TOKEN override API token from configuration
CACHET_DEV set to enable dev logging
```
## Templates
This package makes use of [`text/template`](https://godoc.org/text/template). [Default HTTP template](https://github.com/CastawayLabs/cachet-monitor/blob/master/http.go#L14)
The following variables are available:
| Root objects |
| ------------- | -----------------
| `.SystemName` | system name
| `.API` | `api` object from configuration
| `.Monitor` | `monitor` object from configuration
| `.now` | formatted date string
| Monitor variables |
| ------------------ |
| `.Name` |
| `.Target` |
| `.Type` |
| `.Strict` |
| `.MetricID` |
| ... |
All monitor variables are available from `monitor.go`
## Vision and goals
We made this tool because we felt the need to have our own monitoring software (leveraging on Cachet).
The idea is a stateless program which collects data and pushes it to a central cachet instance.
This gives us power to have an army of geographically distributed loggers and reveal issues in both latency & downtime on client websites.
## Package usage
When using `cachet-monitor` as a package in another program, you should follow what `cli/main.go` does. It is important to call `Validate` on `CachetMonitor` and all the monitors inside.
[API Documentation](https://godoc.org/github.com/CastawayLabs/cachet-monitor)
# Contributions welcome
We'll happily accept contributions for the following (non exhaustive list).
- Implement ICMP check
- Implement TCP check
- Any bug fixes / code improvements
- Test cases

*Notes:* Installation
------------
- `metric_id` is optional 1. Download binary from [release page](https://github.com/CastawayLabs/cachet-monitor/releases)
- `component_id` is optional 2. Create your configuration ([example](https://raw.githubusercontent.com/CastawayLabs/cachet-monitor/master/example.config.json))
- `threshold` is a percentage 3. `cachet-monitor -c /etc/cachet-monitor.config.json`
- `expected_status_code` is a http response code
- GET request will be performed on the `url`
How to run pro tip: run in background using `nohup cachet-monitor 2>&1 > /var/log/cachet-monitor.log &`
----------
Example:
1. Set up [Go](https://golang.org)
2. `go install github.com/castawaylabs/cachet-monitor`
3. `cachet-monitor -c https://raw.githubusercontent.com/CastawayLabs/cachet-monitor/master/example.config.json`
Production:
1. Download the example config and save to `/etc/cachet-monitor.config.json`
2. Run in background: `nohup cachet-monitor 2>&1 > /var/log/cachet-monitor.log &`
``` ```
