memory

This monitor reports memory and memory utilization metrics.

On Linux hosts, this monitor relies on the /proc filesystem. If the underlying host's /proc file system is mounted somewhere other than /proc please specify the path using the top level configuration procPath.

procPath: /proc
monitors:
 - type: memory

Monitor Type: memory

Monitor Source Code

Accepts Endpoints: No

Multiple Instances Allowed: No

Configuration

This monitor has no configuration options.

Metrics

The following table lists the metrics available for this monitor. Metrics that are marked as Included are standard metrics and are monitored by default.

Name Type Included Description
memory.available gauge (Windows Only) Bytes of memory available for use.
memory.buffered gauge ✔ (Linux Only) Bytes of memory used for buffering I/O.
memory.cached gauge ✔ (Linux Only) Bytes of memory used for disk caching.
memory.free gauge ✔ (Linux Only) Bytes of memory available for use.
memory.slab_recl gauge ✔ (Linux Only) Bytes of memory, used for SLAB-allocation of kernel objects, that can be reclaimed.
memory.slab_unrecl gauge ✔ (Linux Only) Bytes of memory, used for SLAB-allocation of kernel objects, that can't be reclaimed.
memory.used gauge ✔ Bytes of memory in use by the system.
memory.utilization gauge ✔ Percent of memory in use on this host. This metric reports with plugin dimension set to "signalfx-metadata".

To specify custom metrics you want to monitor, add a metricsToInclude filter to the agent configuration, as shown in the code snippet below. The snippet lists all available custom metrics. You can copy and paste the snippet into your configuration file, then delete any custom metrics that you do not want sent.

Note that some of the custom metrics require you to set a flag as well as add them to the list. Check the monitor configuration file to see if a flag is required for gathering additional metrics.
