acct_gather.conf - Slurm configuration file for the acct_gather plugins
acct_gather.conf is a UTF8 formatted file which defines parameters used by Slurm's acct_gather related plugins. The file location can be modified at system build time using the DEFAULT_SLURM_CONF parameter or at execution time by setting the SLURM_CONF environment variable. The file will always be located in the same directory as the slurm.conf file. Parameter names are case insensitive but parameter values are case sensitive. 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 configuration 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 appear to be unknown by Slurm and silently ignored. If you decide to change plugin types you may also have to change the related options.
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 approximated to get more accurate task consumption. The adjustment 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 consumption. 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, multiple values can be set with "," separators. The sum of the listed sensors is used for each key. EnergyIPMIPowerSensors is optional, default value is "Node=number" where "number" is the id of the first power sensor returned by ipmi-sensors. i.e. EnergyIPMIPowerSensors=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 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.
Required entry in slurm.conf: AcctGatherEnergyType=acct_gather_energy/xcc Options used for acct_gather_energy/xcc include only in-band communications 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 seconds.
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.
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 compatibility endpoint along with the correct user and password authorization. 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 executed and the port used by the HTTP API. The port used by the HTTP API is the one configured through the bind-address influxdb.conf option in the [http] section. Example: ProfileInfluxDBHost=myinfluxhost:8086 ProfileInfluxDBPass Password for username configured in ProfileInfluxDBUser. Required in v2.x and optional in v1.x InfluxDB. ProfileInfluxDBRTPolicy The InfluxDB v1.x retention policy name for the database configured in ProfileInfluxDBDatabase option. The InfluxDB v2.x retention policy bucket name for the database configured in ProfileInfluxDBDatabase 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. 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 databases, retention policies and such is available on the official webpage. 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 connection 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 SlurmdLogFile. In order to troubleshoot any issues, it is recommended to temporarily 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 InfluxDB. This kind of tool permits one to create dashboards, tables and other graphics using the stored time series.
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.
