Configuring Queue Monitoring

Network analytics queue monitoring provides visibility into the performance and behavior of the data center infrastructure. This feature collects data from the switch, analyzes the data using sophisticated algorithms, and captures the results in reports. You can use the reports to help troubleshoot problems, make decisions, and adjust resources as needed.

You enable queue monitoring by first defining a resource profile template, and then applying the profile to the system (for a global configuration) or to individual interfaces.

Note: You can configure queue monitoring on physical network interfaces only; logical interfaces and Virtual Chassis physical (VCP) interfaces are not supported.

Note: This procedure requires Junos OS Release 13.2X51-D15 to be installed on your device.

To configure queue monitoring on a QFX Series standalone switch:

  1. Configure the queue monitoring polling interval (in milliseconds) globally (for the system):
    [edit]set services analytics resource system polling-interval queue-monitoring interval
  2. Configure a resource profile for the system, and enable queue monitoring:
    [edit]set services analytics resource-profiles profile-name queue-monitoring
  3. Configure high and low values of the depth-threshold (in bytes) for queue monitoring in the system profile:
    [edit]set services analytics resource-profiles profile-name depth-threshold high number low number

    For both high and low values, the range is from 1 to 1,250,000,000 bytes, and the default value is 0 bytes.

    Note: You can configure either the depth-threshold or latency threshold for the system, but not both.

  4. Apply the resource profile template to the system for a global configuration:
    [edit]set services analytics resource system resource-profile profile-name
  5. Configure an interface-specific resource profile and enable queue monitoring for the interface:
    [edit]set services analytics resource-profiles profile-name queue-monitoring
  6. Configure the latency-threshold (high and low values) for queue monitoring in the interface-specific profile:
    [edit]set services analytics resource-profiles profile-name latency-threshold high number low number

    For both high and low values, the range is from 1 to 100,000,000 nanoseconds, and the default value is 1,000,000 nanoseconds.

    Note: You can configure either the depth-threshold or latency threshold for interfaces, but not both.

  7. Apply the resource profile template for interfaces to one or more interfaces:
    [edit]set services analytics resource interfaces interface-name resource-profile profile-name

    Note: If a conflict arises between the system and interface configurations, the interface-specific configuration supersedes the global (system) configuration.
