collectd/vmem

Monitor Type: collectd/vmem (Source)

Accepts Endpoints: No

Multiple Instances Allowed: No

Overview

Collects information about the virtual memory subsystem of the kernel using the collectd vmem plugin. There is no configuration available for this plugin.

This monitor is deprecated in favor of the vmem monitor. The metrics should be fully compatible with this monitor. This monitor will be removed in a future agent release.

Configuration

To activate this monitor in the Smart Agent, add the following to your agent config:

monitors:  # All monitor config goes under this key
 - type: collectd/vmem
   ...  # Additional config

For a list of monitor options that are common to all monitors, see Common Configuration.

This monitor has no configuration options.

Metrics

These are the metrics available for this monitor. Metrics that are categorized as container/host (default) are in bold and italics in the list below.

  • vmpage_faults.majflt (cumulative)
    Number of major page faults on the system
  • vmpage_faults.minflt (cumulative)
    Number of minor page faults on the system
  • vmpage_io.memory.in (cumulative)
    Page Ins for Memory
  • vmpage_io.memory.out (cumulative)
    Page Outs for Memory
  • vmpage_io.swap.in (cumulative)
    Page Ins for Swap
  • vmpage_io.swap.out (cumulative)
    Page Outs for Swap
  • vmpage_number.free_pages (cumulative)
    Number of free memory pages
  • vmpage_number.mapped (cumulative)
    Number of mapped pages
  • vmpage_number.shmem_pmdmapped (gauge)
    The amount of shared (shmem/tmpfs) memory backed by huge pages

Non-default metrics (version 4.7.0+)

To emit metrics that are not default, you can add those metrics in the generic monitor-level extraMetrics config 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 in a running agent instance.
