This is a prometheus exporter to gather the stats of CVMFS clients.
The CernVM File System provides a scalable, reliable and low-maintenance software distribution service. It was developed to assist High Energy Physics (HEP) collaborations to deploy software on the worldwide-distributed computing infrastructure used to run data processing applications. CernVM-FS is implemented as a POSIX read-only file system in user space (a FUSE module). Files and directories are hosted on standard web servers and mounted in the universal namespace /cvmfs.
- prometheus_client
- psutil
- pyxattr
The dependencies are available with RPMs in EPEL or can be installed with pip.
usage: cvmfs-exporter [-h] [--port PORT] [--verbose]
CVMFS exporter for Prometheus
optional arguments:
-h, --help show this help message and exit
--port PORT Collector http port, default is 9868
--verbose increase output verbosity
