In the previous article, we introduced a lot about the Mini OLT design, and next we'll give you detail about the related software function. If the operation people know these software function well, they can distinguish whether the products are designed well. Now, we start with the three core monitoring indicators, they are CPU utilization, memory utilization and temperature. Many operation people only check the datas, but they are unaware of how many potential risks lie behind these sets of data. and then why the three monitoring indicators are the key reference for the daily inspection and troubleshooting. Why are the three monitoring indicators important?
1. Mini OLT’s CPU utilization
The definition of CPU utilization is the percentage of CPU non-idle task runtime against fixed statistical period. This index only reflects the load pressure of the equipment CPU. In general, CPU do not undertake data forwarding work, only deal with protocol interaction, equipment management, OMCI configuration, alarm report, terminal registration and so on. Therefore, the CPU is the most important reference indicator for the total load mean of the whole device. Normally, daily CPU utilization generally ranges from 15% to 60%. When upgrading ONUs in batches or registering a large number of terminals simultaneously on your mini olt gpon 32 onu or mini olt 1 port, the CPU utilization will generate instantaneous peaks and automatically drop back after the task completes.
2. Memory utilization
The definition of memory utilization is percentage of allocated physical memory against the total available physical memory of the board. It can be used for routine inspection to quickly judge overall device health, such as mini olt gpon, mini olt vsol, nokia mini olt. Normally, the daily memory utilization generally ranges from 30% to 70%, and keep stable in the long term operation. When upgrading ONUs in batches or registering a large number of terminals simultaneously, the memory utilization will generate instantaneous peaks and automatically drop back after the task completes. If memory utilization keeps rising without falling back, a memory leak may occur, indicating a bug in the device.
3.Equipment temperature
The temperature of the device is defined by the independent temperature sensor of the critical hardware, the environment and the core device working temperature, which is used to monitor the operating state of the hardware, and prevent the high temperature causes of the device to accelerate aging and even the hardware to burn down. On the market, some of the manufacturers, when produce 1 pon gpon mini olt, mini gpon olt, mini gpon olt 32 onu, have no built-in independent temperature sensors, and only show the temperature by the optical module’s temperature information. Actually, the data of the temperature chip is the most central basis for determining whether the device is overheating, and can adjust the speed of the fan and ensure the stable operation of the equipment.
Many operation people know that the optical module is just one component of the whole device, and its temperature can only represent the temperature of the optical port. In summer, poor ventilation and stacked cabinets already lead to excessive temperatures on the mainboard, but the optical module temperature and the monitoring page still shows normal. At that time the whole equipment may be burn.
4. Conclution
Rayin technology’s Mini OLT is fully compliant with carrier-grade O&M standards. For the three core monitoring indicators including CPU utilization, memory utilization and core chip temperature, the device is fully equipped with built-in multi-level threshold alarms and an automatic closed-loop mechanism. It completely replaces the simplistic design adopted by cheap Mini OLTs available on the market, which only display single values without proactive alarm functions. At the same time, It also enhances the capability for historical operating data traceback, which makes it convenient for the operator to check the fault, analyze the load law and evaluate the health of the device. By using the differential sampling design,monitoring indicators including CPU utilization, memory utilization and device temperature support a maximum 7-day historical data retention period. All historical data supports the visual trend curve display, which can be connected to the alarm event, quickly match the abnormal metric during alarm triggering periods.
Therefore, when purchasing Mini OLT products can not only compare the hardware price, but also check the vendor's complete software function list, some key software function directly determines the future maintenance cost and network stability. If you can't judge what is necessary for your own project, if your existing device lacks required features, Rayin Technology engineers can provide you free technical evaluation and consultation.
