IBMStorwizeMetrics

IBMStorwizeMetrics is a Telegraf input plugin designed to interact with IBM Spectrum Virtualize RESTful API. This plugin enables the gathering and monitoring of metrics from IBM storage solutions that use this API.

Requirements

Go: Ensure you have Go installed on your system to compile the project.
Telegraf: This plugin is intended to be used as a part of Telegraf, which must be installed on your system.

Project Initialization

To get started with the IBMStorwizeMetrics plugin, clone the repository to your local machine:

git clone https://github.com/alex-lata/IBMStorwizeMetrics.git

Gather Dependencies

Navigate to the project directory and run the following command to resolve and tidy up the project's dependencies:

cd IBMStorwizeMetrics  
go mod tidy  # Ensures your project's dependencies are clean and up-to-date

Build the Project

Compile the project using the Go compiler:

go build -o TelegrafIBMStoreWizeMetrics cmd/main.go

This command builds the project and outputs an executable named TelegrafIBMStoreWizeMetrics.

Run Locally

To run the plugin locally, use the following command:

./TelegrafIBMStoreWizeMetrics --config plugins/inputs/IBMStorwizeMetrics/sample.conf

Replace sample.conf with your configuration file if you have a different setup.

Debugging with VSCode

For those who prefer using Visual Studio Code for development, you can set up a launch.json configuration file in the .vscode folder to facilitate debugging:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch Debug",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "program": "${workspaceFolder}/cmd/main.go",
            "args": ["--config", "${workspaceFolder}/plugins/inputs/IBMStorwizeMetrics/sample.conf"],
        }
    ]
}

Running as a Telegraf Plugin

To run IBMStorwizeMetrics as a Telegraf plugin, use the following command:

telegraf --config telegraf.conf

Make sure that telegraf.conf includes the configuration details for this plugin.

Debugging as a Telegraf Plugin

For debugging, run Telegraf in debug mode:

telegraf --config telegraf.conf --debug

This command provides detailed debug output, useful for diagnosing issues or verifying that the plugin is functioning correctly.

Sample Plugin Configuration

Below is a sample configuration for the IBMStorwizeMetrics plugin within Telegraf. This sample shows how to set up the plugin with basic authentication and endpoint details:

[[inputs.IBMStorwizeMetrics]]
  endpoint = "https://IBM_URL:IBM_PORT/rest/v1"
  auth_username = "USERNAME"
  auth_password = "PASSWORD"
  insecure_skip_verify = false
  # Example of an endpoint with the mapptings from the response to tags and fields
  [[inputs.IBMStorwizeMetrics.metrics]]
    endpoint = "/lsnodestats"
    tags = ["node_id", "node_name"]
    fields = ["stat_current", "stat_name", "stat_peak", "stat_peak_time"]
  [[inputs.IBMStorwizeMetrics.metrics]]
    endpoint = "/lsvdisk"
    tags = ["name", "volume_name"]
    fields = ["capacity", "is_snapshot"]

Sample Telegraf Configuration

Below is a sample Telegraf configuration for the IBMStorwizeMetrics plugin.

# Input Plugin: Execd
[[inputs.execd]]
  command = ["[PATH]/TelegrafIBMStoreWizeMetrics", "-config", "[PATH]/IBMStorwizeMetrics/plugins/inputs/IBMStorwizeMetrics/sample.conf"]
  signal = "none"
  interval = "30s"

# Output Plugin: Write metrics to a file
[[outputs.file]]
  files = ["[PATH]/IBMStorwizeMetrics/metrics.out"]
  data_format = "influx"
