ScaleIO monitoring with Netdata

Dell EMC ScaleIO is a software-defined storage product from Dell EMC that creates a server-based storage area network from local application server storage using existing customer hardware or EMC servers.

This module monitors one or more ScaleIO (VxFlex OS) instances via VxFlex OS Gateway API.

It collects metrics for following ScaleIO components:

• System
• Storage Pool
• Sdc

ScaleIO module is tested on:

• VxFlex OS v2.6.1.1_113, REST API v2.5
• VxFlex OS v3.0.0.1_134, REST API v3.0

Configuration

Edit the go.d/scaleio.conf configuration file using edit-config from the Netdata config directory, which is typically at /etc/netdata.

cd /etc/netdata # Replace this path with your Netdata config directory

sudo ./edit-config go.d/scaleio.conf

Needs only url of VxFlex OS Gateway API, MDM username and password. Here is an example for 2 instances:

jobs:

- name: local

url: https://127.0.0.1

username: admin

password: password

tls_skip_verify: yes # self-signed certificate

- name: remote

url: https://203.0.113.10

username: admin

password: password

For all available options please see module configuration file.

Troubleshooting

To troubleshoot issues with the scaleio collector, run the go.d.plugin with the debug option enabled. The output should give you clues as to why the collector isn't working.

First, navigate to your plugins directory, usually at /usr/libexec/netdata/plugins.d/. If that's not the case on your system, open netdata.conf and look for the setting plugins directory. Once you're in the plugin's directory, switch to the netdata user.

cd /usr/libexec/netdata/plugins.d/

sudo -u netdata -s

You can now run the go.d.plugin to debug the collector:

./go.d.plugin -d -m scaleio
