acct_gather.conf(5) Slurm Configuration File acct_gather.conf(5) NAME acct_gather.conf - Slurm configuration file for the acct_gather plugins DESCRIPTION acct_gather.conf is a UTF8 formatted file which defines parameters used by Slurm's acct_gather related plugins. The file will always be lo- cated in the same directory as the slurm.conf. Parameter names are case insensitive but parameter values are case sen- sitive. Any text following a "#" in the configuration file is treated as a comment through the end of that line. The size of each line in the file is limited to 1024 characters. Changes to the configuration file take effect upon restart of the Slurm daemons. The following acct_gather.conf parameters are defined to control the general behavior of various plugins in Slurm. The acct_gather.conf file is different than other Slurm .conf files. Each plugin defines which options are available. Each plugin to be loaded must be specified in the slurm.conf under the following configu- ration entries: • AcctGatherEnergyType (plugin type=acct_gather_energy) • AcctGatherInterconnectType (plugin type=acct_gather_interconnect) • AcctGatherFilesystemType (plugin type=acct_gather_filesystem) • AcctGatherProfileType (plugin type=acct_gather_profile) If the respective plugin for an option is not loaded then that option will be unknown to Slurm, causing the daemon to fatal on initializa- tion. If you decide to change plugin types in slurm.conf, also make sure to change the related options in acct_gather.conf. acct_gather_energy/gpu Required entry in slurm.conf: AcctGatherEnergyType=acct_gather_energy/gpu This plugin doesn't read any options from acct_gather.conf. Dataset provided by the plugin is: Energy. acct_gather_energy/IPMI Required entry in slurm.conf: AcctGatherEnergyType=acct_gather_energy/ipmi Options used for acct_gather_energy/ipmi are as follows: EnergyIPMIFrequency=<number> This parameter is the number of seconds between BMC access samples. EnergyIPMICalcAdjustment=<yes|no> If set to "yes", the consumption between the last BMC access sample and a step consumption update is approx- imated to get more accurate task consumption. The ad- justment is made at the step start and each time the consumption is updated, including the step end. The approximations are not accumulated, only the first and last adjustments are used to calculated the consump- tion. The default is "no". EnergyIPMIPowerSensors=<key=values> Optionally specify the ids of the sensors to used. Multiple <key=values> can be set with ";" separators. The key "Node" is mandatory and is used to know the consumed energy for nodes (scontrol show node) and jobs (sacct). Other keys are optional and are named by administrator. These keys are useful only when profile is activated for energy to store power (in watt) of each key. <values> are integers except when using DCMI. Multiple values can be set with "," sepa- rators. The sum of the listed sensors is used for each key. EnergyIPMIPowerSensors is optional, default value is "Node=<value>" where "<value>" is the id of the first power sensor returned by ipmi-sensors. i.e. EnergyIPMIPowerSen- sors=Node=16,19,23,26;Socket0=16,23;Socket1=19,26;SSUP=23,26;KNC=16,19 EnergyIPMIPowerSensors=Node=29,32;SSUP0=29;SSUP1=32 EnergyIPMIPowerSensors=Node=1280 Data Center Manageability Interface - acct_gather_en- ergy/ipmi supports gathering power data through DCMI IPMI extension commands. When configured, the ipmi plugin will query the DCMI using the "System Power mode" or the "Enhanced System Power Statistics mode" flags depending on the configuration. To configure one or the other, the special sensor val- ues DCMI or DCMI_ENHANCED can be used, for example: EnergyIPMIPowerSensors=Node=DCMI EnergyIPMIPowerSensors=Node=DCMI_ENHANCED The following acct_gather.conf parameters are defined to control the IPMI config default values for libipmiconsole. EnergyIPMIUsername=USERNAME Specify BMC Username. EnergyIPMIPassword=PASSWORD Specify BMC Password. Datasets provided by the plugin have name: <IPMI_SENSOR_LABEL>Power. NOTES: This plugin requires the freeipmi development files to be installed and linkable at configure time. The plugin will not build otherwise. When building the RPM, rpmbuild ... --with freeipmi can be specified to ex- plicitly check for these dependencies. acct_gather_energy/rapl Required entry in slurm.conf: AcctGatherEnergyType=acct_gather_energy/rapl This plugin doesn't read any options from acct_gather.conf. Dataset provided by the plugin is: Power. acct_gather_energy/XCC Required entry in slurm.conf: AcctGatherEnergyType=acct_gather_energy/xcc Options used for acct_gather_energy/xcc include only in-band communica- tions with XClarity Controller, thus a reduced set of configurations is supported: EnergyIPMIFrequency=<number> This parameter is the number of seconds between XCC access samples. Default is 30 seconds. EnergyIPMITimeout=<number> Timeout, in seconds, for initializing the IPMI XCC context for a new gathering thread. Default is 10 sec- onds. Datasets provided by the plugin are: Energy, CurrPower. acct_gather_filesystem/lustre Required entry in slurm.conf: AcctGatherFilesystemType=acct_gather_filesystem/lustre This plugin doesn't read any options from acct_gather.conf. Datasets provided by the plugin are: Reads, ReadMB, Writes, WriteMB. acct_gather_profile/HDF5 Required entry in slurm.conf: AcctGatherProfileType=acct_gather_profile/hdf5 Options used for acct_gather_profile/hdf5 are as follows: ProfileHDF5Dir=<path> This parameter is the path to the shared folder into which the acct_gather_profile plugin will write detailed data (usually as an HDF5 file). The directory is assumed to be on a file system shared by the controller and all compute nodes. This is a required parameter. ProfileHDF5Default A comma-delimited list of data types to be collected for each job submission. Allowed values are: All All data types are collected. (Cannot be combined with other values.) None No data types are collected. This is the default. (Cannot be combined with other values.) Energy Energy data is collected. Filesystem File system (Lustre) data is collected. Network Network (InfiniBand) data is collected. Task Task (I/O, Memory, ...) data is collected. acct_gather_profile/InfluxDB Required entry in slurm.conf: AcctGatherProfileType=acct_gather_profile/influxdb The InfluxDB plugin provides the same information as the HDF5 plugin but will instead send information to the configured InfluxDB server. The InfluxDB plugin is designed against 1.x protocol of InfluxDB. Any site running a v2.x InfluxDB server will need to configure a v1.x com- patibility endpoint along with the correct user and password authoriza- tion. Token authentication is not currently supported. Options: ProfileInfluxDBDatabase InfluxDB v1.x database name where profiling information is to be written. InfluxDB v2.x bucket name where profiling information is to be written. ProfileInfluxDBDefault A comma-delimited list of data types to be collected for each job submission. Allowed values are: All All data types are collected. Cannot be combined with other values. None No data types are collected. This is the default. Cannot be combined with other values. Energy Energy data is collected. Filesystem File system (Lustre) data is collected. Network Network (InfiniBand) data is collected. Task Task (I/O, Memory, ...) data is collected. ProfileInfluxDBHost=<hostname>:<port> The hostname of the machine where the InfluxDB instance is exe- cuted and the port used by the HTTP API. The port used by the HTTP API is the one configured through the bind-address in- fluxdb.conf option in the [http] section. Example: ProfileInfluxDBHost=myinfluxhost:8086 ProfileInfluxDBPass Password for username configured in ProfileInfluxDBUser. Re- quired in v2.x and optional in v1.x InfluxDB. ProfileInfluxDBRTPolicy The InfluxDB v1.x retention policy name for the database config- ured in ProfileInfluxDBDatabase option. The InfluxDB v2.x reten- tion policy bucket name for the database configured in Profile- InfluxDBDatabase option. ProfileInfluxDBUser InfluxDB username that should be used to gain access to the database configured in ProfileInfluxDBDatabase. Required in v2.x and optional in v1.x InfluxDB. This is only needed if InfluxDB v1.x is configured with authentication enabled in the [http] config section and a user has been granted at least WRITE access to the database. See also ProfileInfluxDBPass. ProfileInfluxDBTimeout=<seconds> The maximum time in seconds that an HTTP query to the InfluxDB server can take. After this timeout the data is discarded. Be aware that a long timeout can drain your nodes if the InfluxDB server is unresponsive and, when terminating the job, the last dataset takes more than UnkillableStepTimeout to be sent. Inter- nally, that option sets CURLOPT_TIMEOUT library option. Default is 10 seconds. NOTES: This plugin requires the libcurl development files to be installed and linkable at configure time. The plugin will not build otherwise. Information on how to install and configure InfluxDB and manage data- bases, retention policies and such is available on the official web- page. Collected information is written from every compute node where a job runs to the InfluxDB instance listening on the ProfileInfluxDBHost. In order to avoid overloading the InfluxDB instance with incoming connec- tion requests, the plugin uses an internal buffer which is filled with samples. Once the buffer is full, a HTTP API write request is performed and the buffer is emptied to hold subsequent samples. A final request is also performed when a task ends even if the buffer isn't full. Failed HTTP API write requests are silently discarded. This means that collected profile information in the plugin buffer is lost if it can't be written to the InfluxDB database for any reason. Plugin messages are logged along with the slurmstepd logs to SlurmdLog- File. In order to troubleshoot any issues, it is recommended to tem- porarily increase the slurmd debug level to debug3 and add Profile to the debug flags. This can be accomplished by setting the slurm.conf SlurmdDebug and DebugFlags respectively or dynamically through scontrol setdebug and setdebugflags. Grafana can be used to create charts based on the data held by In- fluxDB. This kind of tool permits one to create dashboards, tables and other graphics using the stored time series. acct_gather_interconnect/OFED Required entry in slurm.conf: AcctGatherInterconnectType=acct_gather_interconnect/ofed Options used for acct_gather_interconnect/ofed are as follows: InfinibandOFEDPort=<number> This parameter represents the port number of the local Infiniband card that we are willing to monitor. The default port is 1. Datasets provided by the plugin: PacketsIn, PacketsOut, InMB, OutMB acct_gather_interconnect/sysfs Required entry in slurm.conf: AcctGatherInterconnectType=acct_gather_interconnect/sysfs Options used for acct_gather_interconnect/sysfs are as follows: SysfsInterfaces=<interfaces> Comma-separated list of interface names to collect statistics from. Usage from all listed interfaces will be summed together, and is not broken down individu- ally. Datasets provided by the plugin: PacketsIn, PacketsOut, InMB, OutMB EXAMPLE ### # Slurm acct_gather configuration file ### # Parameters for acct_gather_energy/impi plugin EnergyIPMIFrequency=10 EnergyIPMICalcAdjustment=yes # # Parameters for acct_gather_profile/hdf5 plugin ProfileHDF5Dir=/app/slurm/profile_data # Parameters for acct_gather_interconnect/ofed plugin InfinibandOFEDPort=1 COPYING Copyright (C) 2012-2013 Bull.
