PMDAAMDGPU(1) General Commands Manual PMDAAMDGPU(1)
pmdaamdgpu - AMD GPU metrics domain agent (PMDA)
$PCP_PMDAS_DIR/amdgpu/pmdaamdgpu [-d domain] [-l logfile] [-t
interval]
pmdaamdgpu is a Performance Metrics Domain Agent (PMDA) which
extracts performance metrics describing the metrics available on
AMD GPU cards via the DRM library.
The amdgpu PMDA exports metrics that measure GPU activity, memory
utilization, temperature, etc on GCN 1.2+ AMD GPUs.
A brief description of the pmdaamdgpu command line options
follows:
-d It is absolutely crucial that the performance metrics domain
number specified here is unique and consistent. That is,
domain should be different for every PMDA on the one host,
and the same domain number should be used for the same PMDA
on all hosts.
-l Location of the log file. By default, a log file named
amdgpu.log is written in the current directory of pmcd(1)
when pmdaamdgpu is started, i.e. $PCP_LOG_DIR/pmcd. If the
log file cannot be created or is not writable, output is
written to the standard error instead.
-t Enables and sets a sampling interval for automatic refreshing
of metric values. The functionality is disabled by default,
however this option allows a time interval to be specified on
which all values are sampled - this has the effect of
constantly updating the accumulating metrics, with the goal
of assisting client tools such as pcp-atop(1) and pmlogger(1)
to observe sub-sample time changes in GPU and process state.
Typically these tools have longer sampling intervals, and can
thus 'miss' activity happening during their sampling
interval.
The amdgpu PMDA is not installed and available by default. If you
want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/amdgpu
# ./Remove
If you want to establish access to the names, help text and values
for the AMD GPU performance metrics once more, after removal, do
the following as root:
# cd $PCP_PMDAS_DIR/amdgpu
# ./Install
pmdaamdgpu is launched by pmcd(1) and should never be executed
directly. The Install and Remove scripts notify pmcd(1) when the
agent is installed or removed.
$PCP_PMCDCONF_PATH
command line options used to launch pmdaamdgpu
$PCP_PMDAS_DIR/amdgpu/help
default help text file for the amdgpu metrics
$PCP_PMDAS_DIR/amdgpu/Install
installation script for the pmdaamdgpu agent
$PCP_PMDAS_DIR/amdgpu/Remove
undo installation script for the pmdaamdgpu agent
$PCP_LOG_DIR/pmcd/amdgpu.log
default log file for error messages and other information
from pmdaamdgpu
Environment variables with the prefix PCP_ are used to configure
the file and directory names used by PCP. On each installation,
the file /etc/pcp.conf contains the local values for these
variables. The $PCP_CONF variable may be used to specify an
alternative configuration file, as described in pcp.conf(5).
PCPIntro(1), pcp-atop(1), pmcd(1), pmlogger(1), pcp.conf(5) and
pcp.env(5).
