cms-perf 0.1.1

Sensor for the XRootD cms.perf directive

Sensor for use in the XRootD cms.perf directive. Measures system load, as well as cpu, memory, and network utilization, to enable load-balancing in a cluster of multiple XRootD servers.

Installation and Usage

Use pip to install the sensor, then configure it using the cms.perf directive.

Installing the sensor

The sensor can be installed using the Python package manager:

python3 -m pip install cms_perf

Note

The psutil dependency requires a C compiler and Python headers. On a RHEL system, use yum install gcc python3-devel to install both. See the psutil documentation for details and other systems.

Installing the sensor creates a cms_perf executable.

When installed for a non-standard Python, such as a venv, the module can be run directly:

python3 -m cms-perf

Configuring xrootd

Add the script or module as the pgm executable of the cms.perf directive. Set the same interval for the directive’s int and the sensor’s --interval.

cms.perf int 5m pgm cms_perf --interval 5m

See the cms.perf documentation for details.
