1. Overview

Monitoring the system resources is very crucial to analyze the health of devices. RBFS has a dedicated daemon called resmond to discover and monitor the device resources. Resmond polls the system resources to gather the status of the resource and store this data in the resource-specific BDS table.

The Resource Monitoring (resmon) functionality of RBFS provides support for monitoring the following components:

  • CPU

  • Memory

  • Processes

  • Disks

  • Sensor

  • Optics

1.1. CPU

Resmond collects CPU hardware information from the global.chassis_0.resource.cpu table. In addition, Resmond calculates CPU usage dynamically and stores this information in the global.chassis_0.resource.cpu_usage table.

1.2. Memory

Resmond collects RAM hardware information from the global.chassis_0.resource.mem table. In addition, Resmond gathers memory usage information in the global.chassis_0.resource.mem_usage table.

1.3. Processes

Resmond collects process usage information of Brick Daemon(BD) that runs in the RBFS and stores the information in the global.chassis_0.resource.proc_usage table. It dynamically gathers the process information and calculates the CPU and the memory usage of the individual Brick Daemons.

1.4. Disks

Resmond collects the disk information from the global.chassis_0.resource.disk table. In addition, Resmond collects disk usage information in the global.chassis_0.resource.disk_usage table.

1.5. Sensor

Resmond collects the reading data of the hardware sensor such as temperature, fan, power-supply, and system LED. The data collected from the sensor are stored in the global.chassis_0.resource.sensor table.

Note The RBFS implementation supports pluggable optics modules on white box switches only.

1.6. System Clock

Resmond provides support for monitoring the system clock so that the system clock is always in sync with the NTP server clock. This ensures that the deviation from the NTP server clock always remains within acceptable limits. Resmond collects the system clock information from the global.os.timex table.

Note The RBFS implementation supports pluggable optics modules on white box switches only.

1.7. Optical Modules

Resmond monitors optical transceivers plugged onto the chassis. It reads transceivers EEPROM (Electrically Erasable Programmable Read-Only Memory) data and translates the data to respective fields in the BDS tables.

Resmond provides the following functionalities for monitoring optical transceivers:

  • Provides a mechanism to discover and monitor optics modules. Supported optics modules include SFP, SFP+, QSFP, QSFP+, and QSFP28 (DAC is not supported).

  • Provides CLIs to write to optics modules

  • Provides show commands to see optics inventory and status of each module

  • Logs the status of the optics module

Note The RBFS implementation supports monitoring of pluggable optics modules on white box switches only.

The following are some of the important tasks (but not limited to) that the Resmond application performs:

  • Optics inventory: Identifying the following brief information of a discovered optics module and stores in table global.chassis_0.resource.optics.inventory.

    • Port

    • Type

    • Vendor

    • Serial Number

    • Part Number

  • Read the following optics data from a module and stores in the table: global.chassis_0.resource.optics.module.

    • RX/TX alarming (loss of light and loss of signal)

  • RX/TX power status

    • Voltage and BIAS status

    • Temperature

  • Write the optics data to an optics module

    • Enabling high power class on QSFP28

    • Shutdown lasers (QSFP28, SFP+ and SFP)

1.7.1. Optics Logging

The Resmond can log the following Optics module events:

  • Temperature high alarm

  • Temperature high warning

  • Temperature low alarm

  • Temperature low warning

  • Voltage high alarm

  • Voltage high warning

  • Voltage low alarm

  • Voltage low warning

  • Lane power high alarm

  • Lane power high warning

  • Lane power low alarm

  • Lane power low warning

  • Lane bias high alarm

  • Lane bias high warning

  • Lane bias low alarm

  • Lane bias low warning

1.8. Q2C Resource Monitoring

Q2C platform resource specific usage metrics are stored in the BDS table: local.bcm.q2c.resource.monitor. Resource usage information enables you to understand the scale of services that the device performs and how it optimally leverages the resource usage.
