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 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.
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 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.
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 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.
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 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.
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.
