.. meta:: :description: The ROCm Data Center tool (RDC) addresses key infrastructure challenges regarding AMD GPUs in cluster and data center environments and simplifies their administration :keywords: RDC plugins, ROCm Data Center plugins, Integrating RDC, Integrating ROCm Data Center .. _rdc-3rd-party: ************************** Third party integration ************************** This section lists available third-party plugins for the RDC tool such as Prometheus, Grafana, and Reliability, Availability and Serviceability (RAS). Python bindings ================ The RDC tool provides a generic Python class ``RdcReader``, which simplifies telemetry gathering by providing the following functionalities: * ``RdcReader`` creates the necessary groups and fieldgroups, watch the fields, and fetch the fields for the telemetry fields specified by the user. * ``RdcReader`` can support embedded and standalone mode. The standalone mode can be with or without authentication. * In standalone mode, the ``RdcReader`` can automatically reconnect to ``rdcd`` if the connection is lost. * Restarting ``rdcd`` can lead to loss of previously created group and fieldgroup. The ``RdcReader`` can recreate them and watch the fields after reconnecting. * If the client is restarted, ``RdcReader`` can detect the previously created groups and fieldgroups and avoid recreating them. * A custom unit converter can be passed to ``RdcReader`` to override the default RDC unit. Here is a sample program to monitor the power and GPU utilization using the ``RdcReader``: .. code-block:: shell from RdcReader import RdcReader from RdcUtil import RdcUtil from rdc_bootstrap import * default_field_ids = [ rdc_field_t.RDC_FI_POWER_USAGE, rdc_field_t.RDC_FI_GPU_UTIL ] class SimpleRdcReader(RdcReader): def __init__(self): RdcReader.__init__(self,ip_port=None, field_ids = default_field_ids, update_freq=1000000) def handle_field(self, gpu_index, value): field_name = self.rdc_util.field_id_string(value.field_id).lower() print("%d %d:%s %d" % (value.ts, gpu_index, field_name, value.value.l_int)) if __name__ == '__main__': reader = SimpleRdcReader() while True: time.sleep(1) reader.process() In the sample program, * Class ``SimpleRdcReader`` is derived from the ``RdcReader``. * The field ``ip_port=None`` in ``RdcReader`` dictates that RDC runs in the embedded mode. * ``SimpleRdcReader::process()`` fetches fields specified in ``default_field_ids``. .. note:: ``RdcReader.py`` can be found in the ``python_binding`` folder located at RDC install path. To run the example, use: .. code-block:: shell # Ensure that RDC shared libraries are in the library path and # RdcReader.py is in PYTHONPATH $ python SimpleReader.py .. _prometheus: Prometheus plugin ================== The Prometheus plugin helps to monitor events and send alerts. Prometheus installation and integration details are explained in the following sections. Prometheus plugin installation ------------------------------- RDC's Prometheus plugin ``rdc_prometheus.py`` can be found in the ``python_binding`` folder. Here are the steps to install Prometheus: 1. Install Prometheus client: .. code-block:: shell $ pip install prometheus_client 2. Run the Prometheus plugin: .. code-block:: shell $ python rdc_prometheus.py 3. Verify plugin: .. code-block:: shell $ curl localhost:5000 gpu_util{gpu_index="0"} 0.0 gpu_clock{gpu_index="0"} 300.0 gpu_memory_total{gpu_index="0"} 4294.0 power_usage{gpu_index="0"} 9.0 gpu_memory_usage{gpu_index="0"} 134.0 By default, the plugin runs in the standalone mode and connects to ``rdcd`` at ``localhost:50051`` to fetch fields. Ensure that the plugin uses the same authentication mode as ``rdcd``, for example, if ``rdcd`` runs with ``-u/--unauth`` option, the plugin must also use ``--rdc_unauth`` option. **Useful options:** - To run the plugin in unauthenticated mode, use the ``--rdc_unauth`` option. - To use the plugin in the embedded mode without ``rdcd``, set the ``--rdc_embedded`` option. - To override the default fields that are monitored, use the ``--rdc_fields`` option to specify the list of fields. - To fetch field's list from a file conveniently, use the ``--rdc_fields_file`` option, if the field's list is long. - To control how the fields are cached, use the ``max_keep_age`` and ``max_keep_samples`` options. - To see the metrics of the plugin itself, including the plugin process CPU, memory, file descriptor usage, native threads count, process start and uptimes, set ``--enable_plugin_monitoring`` option. To view the options provided with the plugin, use ``--help``. .. code-block:: shell % python rdc_prometheus.py --help usage: rdc_prometheus.py [-h] [--listen_port LISTEN_PORT] [--rdc_embedded] [--rdc_ip_port RDC_IP_PORT] [--rdc_unauth] [--rdc_update_freq RDC_UPDATE_FREQ] [--rdc_max_keep_age RDC_MAX_KEEP_AGE] [--rdc_max_keep_samples RDC_MAX_KEEP_SAMPLES] [--rdc_fields RDC_FIELDS [RDC_FIELDS ...]] [--rdc_fields_file RDC_FIELDS_FILE] [--rdc_gpu_indexes RDC_GPU_INDEXES [RDC_GPU_INDEXES ...]] [--enable_plugin_monitoring] RDC Prometheus plugin. optional arguments: -h, --help show this help message and exit --listen_port LISTEN_PORT The listen port of the plugin (default: 5000) --rdc_embedded Run RDC in embedded mode (default: standalone mode) --rdc_ip_port RDC_IP_PORT The rdcd IP and port in standalone mode (default: localhost:50051) --rdc_unauth Set this option if the rdcd is running with unauth in standalone mode (default: false) --rdc_update_freq RDC_UPDATE_FREQ The fields update frequency in seconds (default: 10)) --rdc_max_keep_age RDC_MAX_KEEP_AGE The max keep age of the fields in seconds (default: 3600) --rdc_max_keep_samples RDC_MAX_KEEP_SAMPLES The max samples to keep for each field in the cache (default: 1000) --rdc_fields RDC_FIELDS [RDC_FIELDS ...] The list of fields name needs to be watched, for example, " --rdc_fields RDC_FI_GPU_TEMP RDC_FI_POWER_USAGE " (default: fields in the plugin) --rdc_fields_file RDC_FIELDS_FILE The list of fields name can also be read from a file with each field name in a separated line (default: None) --rdc_gpu_indexes RDC_GPU_INDEXES [RDC_GPU_INDEXES ...] The list of GPUs to be watched (default: All GPUs) --enable_plugin_monitoring Set this option to collect process metrics of the plugin itself (default: false) Prometheus integration ----------------------- To integrate Prometheus plugin in RDC, follow these steps: 1. `Download and install Prometheus plugin `_ in the management machine. 2. Configure Prometheus targets: Use the example configuration file ``rdc_prometheus_example.yml`` in the ``python_binding`` folder. This file refers to ``prometheus_targets.json``. Modify ``prometheus_targets.json`` to point to your compute nodes. Ensure that this is modified to point to the correct compute nodes. .. code-block:: shell // Sample file: prometheus_targets.json // Replace rdc_test*.amd.com to point the correct compute nodes // Add as many compute nodes as necessary [ { "targets": [ "rdc_test1.amd.com:5000", "rdc_test2.amd.com:5000" ] } ] .. note:: In the above example, there are two compute nodes, ``rdc_test1.adm.com`` and ``rdc_test2.adm.com``. Ensure that the Prometheus plugin is running on those compute nodes. 3. Start the Prometheus plugin. .. code-block:: shell % prometheus --config.file= 4. From the management node, open the URL http://localhost:9090 in the browser. 5. Select one of the available metrics. .. figure:: ../data/integration_gpu_clock.png Prometheus image showing GPU clock for both rdc_test1 and rdc_test2. Grafana plugin =============== Grafana is a common monitoring stack used for storing and visualizing time series data. Prometheus acts as the storage backend, and Grafana is used as the interface for analysis and visualization. Grafana has a plethora of visualization options and can be integrated with Prometheus for RDC's dashboard. Grafana plugin installation ---------------------------- To install Grafana plugin, follow these steps: 1. `Download Grafana `_. 2. Follow the instructions to `install Grafana `_. 3. To start Grafana, use: .. code-block:: shell $ sudo systemctl start grafana-server $ sudo systemctl status grafana-server 4. Open http://localhost:3000/ in the browser. 5. Login using the default username and password (``admin``/``admin``) as shown in the following image: .. figure:: ../data/integration_login.png Grafana integration -------------------- As a prerequisite, ensure: * The :ref:`RDC Prometheus plugin ` is running in each compute node. * Prometheus is set up to collect metrics from the plugin. Grafana configuration --------------------- Firstly, add Prometheus as data source using the following steps: 1. Go to "Configuration". .. image:: ../data/integration_config1.png 2. Select "Data Sources". .. image:: ../data/integration_config2.png 3. Go to "Add data source". .. image:: ../data/integration_config3.png 4. Select "Prometheus". .. image:: ../data/integration_config4.png .. note:: Ensure the name of the data source is `Prometheus`. If `Prometheus` and `Grafana` are running on the same machine, use the default URL http://localhost:9090. Otherwise, ensure the URL matches the `Prometheus` URL, save, and test it. .. image:: ../data/integration_config5.png Then, import RDC dashboard using the following steps: 1. Go to "+" and select "Import". 2. Upload ``rdc_grafana_dashboard_example.json`` from the ``python_binding`` folder. 3. Select the desired compute node for visualization. .. image:: ../data/integration_config6.png Prometheus (Grafana) integration with automatic node detection ============================================================== RDC provides Consul to discover the ``rdc_prometheus`` service automatically. Consul is a service mesh solution providing a fully featured control plane with service discovery, configuration, and segmentation functionality. For more information, see `Consul `_. RDC uses Consul for health checks of RDC's integration with the Prometheus plugin (``rdc_prometheus``). These checks provide information on its efficiency. With the Consul agent integration, a new compute node can be discovered automatically, which saves users from manually changing ``prometheus_targets.json`` to use Consul. Installing the Consul agent for compute and management nodes ------------------------------------------------------------ To install the latest Consul agent for compute and management nodes, follow these steps: 1. To download and install the Consul agent, set up the ``apt`` repository: .. code-block:: shell $ curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo apt-key add - $ sudo apt-add-repository "deb [arch=amd64] https://apt.releases.hashicorp.com $(lsb_release -cs) main" $ sudo apt-get update && sudo apt-get install consul 2. Generate a key to encrypt the communication between Consul agents. The same key is used by both the compute and management nodes for communication. .. code-block:: shell $ consul keygen For demonstration purposes, the following key is used in the configuration file: .. code-block:: shell $ consul keygen 4lgGQXr3/R2QeTi5vEp7q5Xs1KoYBhCsk9+VgJZZHAo= Setting up the Consul server in management nodes ------------------------------------------------- While Consul can function with one server, it's recommended to use three to five servers to avoid failure scenarios leading to data loss. .. note:: For demonstration purposes, the configuration settings documented below are for a single server. To set up ``Consul`` server, follow these steps: 1. Create a configuration file ``/etc/consul.d/server.hcl``. .. code-block:: shell server = true encrypt = "" bootstrap_expect = 1 ui = true client_addr = "0.0.0.0" bind_addr = "" Here is how to use the variables in the configuration file: * Run the agent in server mode by setting ``server`` to ``true``. * Set ``encrypt`` to the key generated in the first step. * The ``bootstrap_expect`` variable indicates the number of servers required to form the first Consul cluster. Set this variable to ``1`` to allow a cluster with a single server. * The User Interface (``ui``) variable when set to ``true`` enables the Consul web UI. * The ``client_addr`` variable is used to connect the API and UI. * The ``bind_addr`` variable is used to connect the client to the server. If you have multiple private IP addresses, use the address that can connect to a client. 2. Start the agent. .. code-block:: shell $ sudo consul agent -config-dir=/etc/consul.d/ 3. Browse to http://localhost:8500/ on the management node to see a single instance running. Setting up the Consul client in compute nodes --------------------------------------------- To set up Consul client, follow these steps: 1. Create a configuration file ``/etc/consul.d/client.hcl``. .. code-block:: shell server = false encrypt = "" retry_join = [""] client_addr = "0.0.0.0" bind_addr = "" .. note:: Use the same ``CONSUL_ENCRYPTION_KEY`` as the servers. In the ``retry_join``, use the IP address of the management nodes. 2. Start the Consul agent. .. code-block:: shell $ sudo consul agent -config-dir=/etc/consul.d/ To see if the client has joined the Consul, use: .. code-block:: shell $ consul members Node Address Status Type Build Protocol DC Segment management-node 10.4.22.70:8301 alive server 1.9.3 2 dc1 compute-node 10.4.22.112:8301 alive client 1.9.3 2 dc1 3. Set up the Consul client to monitor the health of the RDC Prometheus plugin. 4. Start the RDC Prometheus plugin. .. code-block:: shell $ python rdc_prometheus.py --rdc_embedded 5. Add the configuration file ``/etc/consul.d/rdc_prometheus.hcl``. .. code-block:: shell { "service": { "name": "rdc_prometheus", "tags": [ "rdc_prometheus", "rdc" ], "port": 5000, "check": { "id": "rdc_plugin", "name": "RDC Prometheus plugin on port 5000", "http": "http://localhost:5000", "method": "GET", "interval": "15s", "timeout": "1s" } } } .. note:: By default, the Prometheus plugin uses port 5000. If you don't use the default setting, change the configuration file accordingly. 6. After updating the configuration file, restart the Consul client agent. .. code-block:: shell $ sudo consul agent -config-dir=/etc/consul.d/ 7. Enable the :ref:`Prometheus ` integration in the management node. 8. In the management node, inspect the service. .. code-block:: shell $ consul catalog nodes -service=rdc_prometheus Node ID Address DC compute-node 76694ab1 10.4.22.112 dc1 9. Create a new Prometheus configuration ``rdc_prometheus_consul.yml`` file for the Consul integration. .. code-block:: shell global: scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute. evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute. scrape_configs: - job_name: 'consul' consul_sd_configs: - server: 'localhost:8500' relabel_configs: - source_labels: [__meta_consul_tags] regex: .*,rdc,.* action: keep - source_labels: [__meta_consul_service] target_label: job .. note:: When running the Consul server and Prometheus on the same machine, change the server under ``consul_sd_configs`` to your Consul server address. 10. Start Prometheus. .. code-block:: shell $ ./prometheus --config.file="rdc_prometheus_consul.yml" 11. Browse the Prometheus UI at http://localhost:9090 on the management node and query RDC Prometheus metrics. Ensure that the plugin starts before running the query. Reliability, Availability, and Serviceability plugin ===================================================== The Reliability, Availability, and Serviceability plugin (RAS) plugin helps to monitor and count ECC (Error-Correcting Code) errors. The following sections provide information on integrating RAS with RDC. RAS plugin installation ------------------------ With the RAS feature enabled in the graphic card, you can use RDC to monitor RAS errors. Prerequisite ^^^^^^^^^^^^^ - Ensure that the GPU supports RAS. .. note:: The RAS library is installed as part of the RDC installation. No additional configuration is required for RDC. - RDC installation dynamically loads the RAS library ``librdc_ras.so``. The configuration files required by the RAS library are installed in the ``sp3`` and ``config`` folders. .. code-block:: shell % ls /opt/rocm-4.2.0/rdc/lib ... librdc_ras.so ... ... sp3 ... config ... RAS integration ---------------- RAS exposes a list of ECC correctable and uncorrectable errors for different IP blocks and helps to troubleshoot issues. **Example:** .. code-block:: shell $ rdci dmon -i 0 -e 600,601 Where, the ``dmon`` command monitors GPU index 0, and fields 600 and 601, where 600 is the field ID for the ``ECC_CORRECT`` counter and 601 for the ``ECC_UNCORRECT`` counter. .. code-block:: shell % rdci dmon -l ... ... 600 RDC_FI_ECC_CORRECT_TOTAL : Accumulated Single Error Correction 601 RDC_FI_ECC_UNCORRECT_TOTAL : Accumulated Double Error Detection 602 RDC_FI_ECC_SDMA_CE : SDMA Correctable Error 603 RDC_FI_ECC_SDMA_UE : SDMA Uncorrectable Error 604 RDC_FI_ECC_GFX_CE : GFX Correctable Error 605 RDC_FI_ECC_GFX_UE : GFX Uncorrectable Error 606 RDC_FI_ECC_MMHUB_CE : MMHUB Correctable Error 607 RDC_FI_ECC_MMHUB_UE : MMHUB Uncorrectable Error 608 RDC_FI_ECC_ATHUB_CE : ATHUB Correctable Error 609 RDC_FI_ECC_ATHUB_UE : ATHUB Uncorrectable Error 610 RDC_FI_ECC_PCIE_BIF_CE : PCIE_BIF Correctable Error 611 RDC_FI_ECC_PCIE_BIF_UE : PCIE_BIF Uncorrectable Error 612 RDC_FI_ECC_HDP_CE : HDP Correctable Error 613 RDC_FI_ECC_HDP_UE : HDP Uncorrectable Error 614 RDC_FI_ECC_XGMI_WAFL_CE : XGMI WAFL Correctable Error 615 RDC_FI_ECC_XGMI_WAFL_UE : XGMI WAFL Uncorrectable Error 616 RDC_FI_ECC_DF_CE : DF Correctable Error 617 RDC_FI_ECC_DF_UE : DF Uncorrectable Error 618 RDC_FI_ECC_SMN_CE : SMN Correctable Error 619 RDC_FI_ECC_SMN_UE : SMN Uncorrectable Error 620 RDC_FI_ECC_SEM_CE : SEM Correctable Error 621 RDC_FI_ECC_SEM_UE : SEM Uncorrectable Error 622 RDC_FI_ECC_MP0_CE : MP0 Correctable Error 623 RDC_FI_ECC_MP0_UE : MP0 Uncorrectable Error 624 RDC_FI_ECC_MP1_CE : MP1 Correctable Error 625 RDC_FI_ECC_MP1_UE : MP1 Uncorrectable Error 626 RDC_FI_ECC_FUSE_CE : FUSE Correctable Error 627 RDC_FI_ECC_FUSE_UE : FUSE Uncorrectable Error 628 RDC_FI_ECC_UMC_CE : UMC Correctable Error 629 RDC_FI_ECC_UMC_UE : UMC Uncorrectable Error 630 RDC_FI_ECC_MCA_CE : MCA Correctable Error 631 RDC_FI_ECC_MCA_UE : MCA Uncorrectable Error 632 RDC_FI_ECC_VCN_CE : VCN Correctable Error 633 RDC_FI_ECC_VCN_UE : VCN Uncorrectable Error 634 RDC_FI_ECC_JPEG_CE : JPEG Correctable Error 635 RDC_FI_ECC_JPEG_UE : JPEG Uncorrectable Error 636 RDC_FI_ECC_IH_CE : IH Correctable Error 637 RDC_FI_ECC_IH_UE : IH Uncorrectable Error 638 RDC_FI_ECC_MPIO_CE : MPIO Correctable Error 639 RDC_FI_ECC_MPIO_UE : MPIO Uncorrectable Error ... ... To access the ECC correctable and uncorrectable error counters, use: .. _error-correction: .. code-block:: shell % rdci dmon -i 0 -e 600,601 GPU ECC_CORRECT ECC_UNCORRECT 0 0 0 0 0 0 0 0 0
