Memory usage π
Description π
The Splunk Distribution of OpenTelemetry Collector provides this integration as the memory
monitor type by using the SignalFx Smart Agent Receiver. This monitor type sends memory usage stats for the underlying host. This monitor type is available on Kubernetes, Linux, and Windows.
On Linux hosts, this monitor type relies on the /proc
filesystem. If the underlying hostβs /proc
file system is mounted somewhere other than /proc
, specify the path using the top-level configuration procPath
, as shown in the following example:
procPath: /proc
monitors:
- type: memory
Benefits π
After you configure the integration, you can access these features:
View metrics. You can create your own custom dashboards, and most monitors provide built-in dashboards as well. For information about dashboards, see View dashboards in Observability Cloud.
View a data-driven visualization of the physical servers, virtual machines, AWS instances, and other resources in your environment that are visible to Infrastructure Monitoring. For information about navigators, see Splunk Infrastructure Monitoring navigators.
Access the Metric Finder and search for metrics sent by the monitor. For information, see Use the Metric Finder.
Installation π
Follow these steps to deploy this integration:
Deploy the Splunk Distribution of OpenTelemetry Collector to your host or container platform:
Configure the monitor, as described in the Configuration section.
Restart the Splunk Distribution of OpenTelemetry Collector.
Configuration π
This monitor type is available in the Smart Agent Receiver, which is part of the Splunk Distribution of OpenTelemetry Collector. You can use existing Smart Agent monitors as OpenTelemetry Collector metric receivers with the Smart Agent Receiver.
This monitor type requires a properly configured environment on your system in which youβve installed a functional Smart Agent release bundle. The Collector provides this bundle in the installation paths for x86_64/amd64
.
To activate this monitor type in the Collector, add the following lines to your configuration (YAML) file:
monitors:
smartagent/collectd/memory:
type: collectd/memory
... # Additional config
To complete the integration, include the monitor type in a metrics pipeline. Add the monitor type to the service/pipelines/metrics/receivers
section of your configuration file. For example:
service:
pipelines:
metrics:
receivers: [smartagent/memory]
To collect memory utilization metrics only, use the Host metrics receiver.
Metrics π
The following metrics are available for this integration:
To emit metrics that are not default, you can add those metrics in the generic monitor-level extraMetrics
configuration option. Metrics that are derived from specific configuration options that do not appear in the above list of metrics do not need to be added to extraMetrics.
To see a list of metrics that will be emitted, you can run agent-status monitors
after configuring this monitor type in a running agent instance.
