Part 2: Install the OpenTelemetry Collector to send server and cluster data
Use the OpenTelemetry Collector to collect and send data from your infrastructure, including hosts, servers, and clusters.
Install the Splunk Distribution of OpenTelemetry Collector on any hosts or clusters you’re using as a part of your infrastructure, such as servers running in your data center or on a virtual machine running in the cloud to:
-
Send metrics to Infrastructure Monitoring
-
Query logs in Log Observer Connect
-
Set up your environment to receive logs and traces from applications instrumented in Part 1: Instrument back-end services and applications to send traces, logs, and metrics.
Install the OpenTelemetry Collector for your servers or clusters
To receive infrastructure data from your servers and clusters, install and configure the Splunk Distribution of OpenTelemetry Collector for your server or cluster.
The OpenTelemetry Collector runs as an application or pod and listens for telemetry data from your servers or clusters. After finding data, the Collector sends it to Splunk Infrastructure Monitoring. To learn more about the Collector, see Get started: Understand and use the Collector.
Guided setup
For a quick setup, you can follow a guided installation process through the Splunk Observability Cloud UI. To do so, see the documentation corresponding to your platform:
-
Linux: Collect Linux data
-
Kubernetes: Collect Kubernetes data
-
Windows: Collect Windows data
Manual setup
If you’re planning to use a more advanced setup for the OpenTelemetry Collector, you can manually install and configure the Collector. To do so, follow the setup guide corresponding to your platform:
View your infrastructure data in Splunk Infrastructure Monitoring
After you’ve installed the Collector and configured your servers and clusters, you can use the following methods to access your data:
If you can see your data in navigators, dashboards, or in the metric finder, then your integration is working.
View metrics in Infrastructure Monitoring navigators
Splunk Observability Cloud uses navigators to display information about hosts and clusters.
For example, the host navigator shows charts and other visualizations of host data:
To learn how to use Infrastructure Monitoring navigators, see the following:
View metrics in built-in dashboards for hosts and Kubernetes
Splunk Observability Cloud offers built-in dashboards that display charts for your infrastructure metrics. To find your metrics in these dashboards, see Built-in dashboards.
Search for metrics using the metric finder
You can find your infrastructure metrics by using the Splunk metric finder. For more details, see Search for metrics in the Metric Finder.
Query logs in Log Observer Connect
If you chose to ingest logs, you can query them in the Splunk Log Observer Connect. See more at Introduction to Splunk Log Observer Connect.
