vCenter Integration

Use this guide to collect VMware vCenter metrics in KloudMate with OpenTelemetry vcenter receiver running via the KloudMate Agent.

Prerequisites

1. Run vCenter 7.0 or 8.x.
2. Create a read-only vSphere user with access to the vCenter server, clusters, and resources you want to monitor.
3. Identify the vCenter or ESXi endpoint with SDK access enabled.
4. Install the KloudMate Agent on a host that can reach vCenter.

Step 1: Open the Collector Configuration

1. Go to Settings → Agents.
2. Find the agent you want to configure and select the three dots.
3. Choose Configure.
4. Go to Collector config.

Step 2: Add the vCenter Configuration

Add the following configuration. Replace the endpoint and credentials to match your environment.

• If the agent runs in managed mode, add it to the Custom config override section. See Custom config override.
• If the agent runs in manual mode, add it directly to the collector configuration.

receivers:
  vcenter:
    endpoint: https://vcenter.example.com/sdk
    username: <username>
    password: <password>
    collection_interval: 1m
    initial_delay: 1s
    tls:
      insecure: true

service:
  pipelines:
    metrics/vcenter:
      receivers:
        - vcenter
      processors:
        - batch
      exporters:
        - otlphttp

If you need to disable specific metrics, add them under the metrics section of the receiver configuration.

Step 3: Save the Configuration

Click Save. The Agent restarts and applies the new configuration.

Step 4: Validate in KloudMate

After the Agent restarts:

• open Explore
• query vCenter metrics such as vcenter_host_cpu_utilization or vcenter_vm_memory_usage
• build dashboards and alerts once the data is visible
