In this digital age, keeping an eye on system metrics is compulsory for maintaining optimal performance. Ostent is a powerful tool that helps in collecting and reporting critical system metrics to various platforms such as InfluxDB, Graphite, and Librato. Think of it as your system’s dedicated watchman, continuously reporting back on the health and status of your operating environment.

What Metrics Does Ostent Collect?

Ostent tirelessly watches over your system and collects the following vital statistics:

• RAM and swap usage
• CPU usage and load average
• Disk space usage (both in bytes and inodes)
• Network data including bytes, packets, drops, and errors

It’s important to note that Ostent’s “process top” feature is available only for on-display viewing.

Installation Guide

Installing Ostent is straightforward since it is distributed as a single executable. Here’s how to get started:

sh
curl -L https://github.com/ostrost/ostent/releases/download/v0.7.0/$(uname -s)-$(uname -m).tar.xz | tar Jxf -

This command will extract the executable directly to your usr/bin/ostent directory. To enable system-wide installation, you need to use sudo with the command.

Supported Platforms

• Linux
• FreeBSD
• Mac OS X

Using Ostent

To get started with Ostent, simply open a terminal and run:

$ ostent -h

This command will provide you with the necessary usage details, including available flags like:

• --bind: specifies the server bind address.
• --bind-port: defines the server bind port.
• --config: sets the config filename.
• --interval: indicates the metrics collection interval.
• --log-requests: logs server requests.
• --upgrade-checks: enables periodic upgrade checks.
• --version: prints the version and exits.

Configuring Ostent

Ostent’s configuration is compatible with the Telegraf settings. To enable reporting to InfluxDB, your configuration file should have the following:

[outputs]
  [outputs.influxdb]
    database = "ostent"
    urls = ["http://127.0.0.1:8086"]

You can similarly configure output for Graphite and Librato.

Running the Code

To run Ostent, simply execute the following commands:

go get github.com/ostrost/ostent
ostent

Rebuilding Ostent

If you need to rebuild Ostent, follow these steps:

1. Navigate to the Ostent directory:

cd $(go list -f '{{.Dir}}' github.com/ostrost/ostent)

2. Initialize the environment:

make init

3. Sort out npm packages (optional):

npm install

4. Watch for changes or execute the make command:

gulp watch

Troubleshooting Tips

While Ostent is a robust system metrics monitoring tool, you might encounter issues along the way. Here are some troubleshooting ideas:

• Ensure you have the necessary permissions when installing Ostent, especially when using sudo.
• Check that your configuration file is correctly set up and that your specified URLs are accessible.
• If Ostent fails to start, review the output for any error messages that may guide you to the root cause.
• Consult the [Telegraf configuration documentation](https://github.com/influxdata/telegraf/blob/master/docs/CONFIGURATION.md#agent-configuration) for additional guidelines.
