memstat collector

  "memstat": {
    "exclude_metrics": [
      "mem_buffera"
    ],
    "only_metrics": [
      "mem_total",
      "mem_free",
      "mem_cached",
      "mem_used"
    ]
  }

The memstat collector reads data from /proc/meminfo and outputs a handful node metrics. If a metric is not required, it can be excluded from forwarding it to the sink.

Both filtering mechanisms are supported:

• exclude_metrics: Excludes the specified metrics.
• only_metrics: If provided, only the listed metrics are collected. This takes precedence over exclude_metrics.

Metrics:

• mem_total
• mem_sreclaimable
• mem_slab
• mem_free
• mem_buffers
• mem_cached
• mem_available
• mem_shared
• swap_total
• swap_free
• mem_used = mem_total - (mem_free + mem_buffers + mem_cached)
