What basic metrics does Managed Service for Prometheus support for container clusters?-Managed Service for Prometheus(Prometheus)-阿里云帮助中心

This topic describes the basic metrics that Managed Service for Prometheus collects from container clusters.

Important

Managed Service for Prometheus charges based on write volume or the number of data points reported. Metrics are categorized into two types:
- Basic metrics: Managed Service for Prometheus does not charge for basic metrics collected from Alibaba Cloud Container Service, such as ACK, ACS, ASK, ACK One, and ACK Edge. This benefit does not extend to other types of container clusters.
- Custom metrics: All other metrics are custom metrics. Billing for custom metrics started on January 6, 2020.
Effective 00:00:00 on November 12, 2024 (UTC+8), Managed Service for Prometheus will adjust the scope of basic metrics collected from Alibaba Cloud Container Service clusters.

Only the basic metrics described in this topic are collected from container clusters by default.

Any other container cluster metrics are custom metrics and are billable. For billing standards, see Prometheus instance billing.

If a container requests only graphics memory, this metric is 0, indicating no limit on computing power. For example, if a GPU has 100 units of computing power and 30 units are allocated to a container, the allocated ratio is 30/100 = 0.3.
DCGM_CUSTOM_CONTAINER_MEM_ALLOCATED	Graphics memory allocated to the container, in bytes.

DCGM_FI_DEV_GPU_TEMP	GPU temperature, in degrees Celsius.
DCGM_FI_DEV_GPU_UTIL	The GPU utilization, which represents the percentage of time over a sample period (e.g., 1s or 1/6s, depending on the GPU product) when one or more kernel functions were active. This metric shows that GPU resources are in use by a kernel function, but does not detail the intensity of that use.
DCGM_FI_DEV_MEM_CLOCK	Memory clock frequency, in MHz.
DCGM_FI_DEV_MEM_COPY_UTIL	Memory bandwidth utilization. For example, an NVIDIA V100 GPU has a maximum memory bandwidth of 900 GB/s. If the current memory bandwidth is 450 GB/s, the utilization is 50%.

DCGM_FI_PROF_DRAM_ACTIVE	The fraction of cycles during which data is sent to or received from the device memory. This metric represents memory bandwidth utilization. This value is an average over a time interval, not an instantaneous value. A higher value indicates higher device memory utilization. A value of 1.0 (100%) means a DRAM instruction was executed every cycle during the interval. In practice, the maximum achievable value is approximately 0.8 (80%). For example, a value of 0.2 (20%) means that for 20% of the cycles in the interval, device memory was read from or written to.
DCGM_FI_PROF_NVLINK_RX_BYTES	Data receive rate over NVLink, excluding protocol headers. This value is an average over a time interval, not an instantaneous value. The rate is averaged over the interval. For example, transferring 1 GB of data in 1 second results in a rate of 1 GB/s, regardless of whether the transfer occurred at a constant rate or in a burst. The theoretical maximum bandwidth for NVLink Gen2 is 25 GB/s per link in each direction.
DCGM_FI_PROF_NVLINK_TX_BYTES	Total bytes transmitted (sent) over NVLink.
DCGM_FI_PROF_PCIE_RX_BYTES	Data receive rate over the PCIe bus, including protocol headers and data payload. This value is an average over a time interval, not an instantaneous value. The rate is averaged over the interval. For example, transferring 1 GB of data in 1 second results in a rate of 1 GB/s, regardless of whether the transfer occurred at a constant rate or in a burst. The theoretical maximum bandwidth for PCIe Gen3 is 985 MB/s per lane.
DCGM_FI_PROF_PCIE_TX_BYTES	Data transmission rate over the PCIe bus, including protocol headers and data payload. This value is an average over a time interval, not an instantaneous value. The rate is averaged over the interval. For example, transferring 1 GB of data in 1 second results in a rate of 1 GB/s, regardless of whether the transfer occurred at a constant rate or in a burst. The theoretical maximum bandwidth for PCIe Gen3 is 985 MB/s per lane.
DCGM_FI_PROF_PIPE_TENSOR_ACTIVE	The fraction of cycles the Tensor (HMMA/IMMA) pipe is active. This value is an average over a time interval, not an instantaneous value. A higher value indicates higher utilization of the Tensor Cores. A value of 1.0 (100%) means a Tensor instruction was issued every other cycle, as one instruction takes two cycles to complete. A value of 0.2 (20%) could indicate any of the following scenarios: 20% of SMs ran their Tensor Cores at 100% utilization throughout the interval. 100% of SMs ran their Tensor Cores at 20% utilization throughout the interval. 100% of SMs ran their Tensor Cores at 100% utilization for one-fifth of the interval. Other combinations.
DCGM_FI_PROF_SM_ACTIVE	The percentage of time during an interval that at least one warp was active on a streaming multiprocessor (SM). This value is an average across all SMs and is not sensitive to the number of threads per block. A warp is considered active if it is scheduled and its resources are allocated, regardless of whether it is computing or in a non-computing state (e.g., waiting for a memory request). A value below 0.5 indicates inefficient GPU utilization, while a value above 0.8 is desirable. For a GPU with N SMs, consider these examples: If a kernel function runs with N thread blocks on all SMs for the entire interval, the value is 1 (100%). If a kernel function runs with N/5 thread blocks during the interval, the value is 0.2. If a kernel function runs with N thread blocks but for only one-fifth of the interval, the value is 0.2.
machine_cpu_cores	Number of CPU cores on the machine.
node_exporter_build_info	Build information for the node exporter.
nvidia_gpu_duty_cycle	The percentage of time over the last sample period during which one or more kernel functions were executing on the GPU.
