Dell EMC ScaleIO

Plugin: go.d.plugin Module: scaleio

Overview

This collector monitors ScaleIO (VxFlex OS) instances via VxFlex OS Gateway API.

It collects metrics for the following ScaleIO components:

  • System
  • Storage Pool
  • Sdc

This collector is supported on all platforms.

This collector supports collecting metrics from multiple instances of this integration, including remote instances.

Default Behavior

Auto-Detection

This integration doesn’t support auto-detection.

Limits

The default configuration for this integration does not impose any limits on data collection.

Performance Impact

The default configuration for this integration is not expected to impose a significant performance impact on the system.

Setup

Prerequisites

No action required.

Configuration

File

The configuration file name for this integration is go.d/scaleio.conf.

You can edit the configuration file using the edit-config script from the Netdata config directory.

cd /etc/netdata 2>/dev/null || cd /opt/netdata/etc/netdata
sudo ./edit-config go.d/scaleio.conf

Options

The following options can be defined globally: update_every, autodetection_retry.

autodetection_retry Recheck interval in seconds. Zero means no recheck will be scheduled. 0 no
url Server URL. https://127.0.0.1:80 yes
timeout HTTP request timeout. 1 no
username Username for basic HTTP authentication. yes
password Password for basic HTTP authentication. yes
proxy_url Proxy URL. no
proxy_username Username for proxy basic HTTP authentication. no
proxy_password Password for proxy basic HTTP authentication. no
method HTTP request method. GET no
body HTTP request body. no
headers HTTP request headers. no
not_follow_redirects Redirect handling policy. Controls whether the client follows redirects. no no
tls_skip_verify Server certificate chain and hostname validation policy. Controls whether the client performs this check. no no
tls_ca Certification authority that the client uses when verifying the server’s certificates. no
tls_cert Client TLS certificate. no
tls_key Client TLS key. no

Examples

Basic

An example configuration.

jobs:
  - name: local
    url: https://127.0.0.1
    username: admin
    password: password
    tls_skip_verify: yes  # self-signed certificate
Multi-instance

Note: When you define multiple jobs, their names must be unique.

Local and remote instance.

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
    tls_skip_verify: yes

Metrics

Metrics grouped by scope.

The scope defines the instance that the metric belongs to. An instance is uniquely identified by a set of labels.

Per Dell EMC ScaleIO instance

These metrics refer to the entire monitored application.

This scope has no labels.

Metrics:

Metric Dimensions Unit
scaleio.system_capacity_total total KiB
scaleio.system_capacity_in_use in_use KiB
scaleio.system_capacity_usage thick, decreased, thin, snapshot, spare, unused KiB
scaleio.system_capacity_available_volume_allocation available KiB
scaleio.system_capacity_health_state protected, degraded, in_maintenance, failed, unavailable KiB
scaleio.system_workload_primary_bandwidth_total total KiB/s

scaleio.system_defined_components devices, fault_sets, protection_domains, rfcache_devices, sdc, sds, snapshots, storage_pools, volumes, vtrees components
scaleio.system_components_volumes_by_type thick, thin volumes
scaleio.system_components_volumes_by_mapping mapped, unmapped volumes

Per storage pool

These metrics refer to the storage pool.

This scope has no labels.

Metrics:

Metric Dimensions Unit
scaleio.storage_pool_capacity_total total KiB
scaleio.storage_pool_capacity_in_use in_use KiB
scaleio.storage_pool_capacity_usage thick, decreased, thin, snapshot, spare, unused KiB
scaleio.storage_pool_capacity_utilization used percentage
scaleio.storage_pool_capacity_available_volume_allocation available KiB
scaleio.storage_pool_capacity_health_state protected, degraded, in_maintenance, failed, unavailable KiB
scaleio.storage_pool_components devices, snapshots, volumes, vtrees components

Per sdc

These metrics refer to the SDC (ScaleIO Data Client).

This scope has no labels.

Metrics:

Metric Dimensions Unit
scaleio.sdc_mdm_connection_state connected boolean
scaleio.sdc_bandwidth read, write KiB/s
scaleio.sdc_iops read, write iops/s
scaleio.sdc_io_size read, write KiB
scaleio.sdc_num_of_mapped_volumed mapped volumes

Alerts

There are no alerts configured by default for this integration.

Troubleshooting

Debug Mode

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.

  • Navigate to the plugins.d directory, usually at /usr/libexec/netdata/plugins.d/. If that’s not the case on your system, open netdata.conf and look for the plugins setting under [directories].

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

  • Switch to the netdata user.

    sudo -u netdata -s

  • Run the go.d.plugin to debug the collector:

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

Getting Logs

If you’re encountering problems with the scaleio collector, follow these steps to retrieve logs and identify potential issues:

  • Run the command specific to your system (systemd, non-systemd, or Docker container).
  • Examine the output for any warnings or error messages that might indicate issues. These messages should provide clues about the root cause of the problem.

System with systemd

Use the following command to view logs generated since the last Netdata service restart:

journalctl _SYSTEMD_INVOCATION_ID="$(systemctl show --value --property=InvocationID netdata)" --namespace=netdata --grep scaleio

System without systemd

Locate the collector log file, typically at /var/log/netdata/collector.log, and use grep to filter for collector’s name:

grep scaleio /var/log/netdata/collector.log

Note: This method shows logs from all restarts. Focus on the latest entries for troubleshooting current issues.

Docker Container

If your Netdata runs in a Docker container named “netdata” (replace if different), use this command:

docker logs netdata 2>&1 | grep scaleio
