Hey there,
I am looking for some feedback on 2x enhancement / blueprint proposals for the
‘file’ publisher in ceilometer.
i.e.
https://github.com/openstack/ceilometer/blob/master/ceilometer/publisher/file.py
Are the Ceilometer owners open to looking at blueprints for the following ?
1. Compression of files (within file rotation) to minimize disk usage and
minimize bandwidth in FTP-ing these files off server
o i.e. as part of file rotation, the newly rotated file would be gzip’d to
compress the file
o this would be an optional parameter in the pipeline definition in
/etc/ceilometer/pipeline.yaml
e.g.
name: meter_file
meters:
- "*"
publishers:
- file:///var/test?max_bytes=10000000&backup_count=5&compress=true
o again,
minimizing disk usage and minimizing network bandwidth in FTP-ing these files
off server.
2. CSV (Comma Separated Values) File Format
o CSV is widely supported for many off-box Statistical Analysis-type Tools;
especially in Telecom,
o again this would be done as an optional argument to the file publisher
§ the existing format (python dictionary print) would remain as the default
format
§ ‘format=csv’ would be the argument added to the publisher line in order to
enable CSV format
e.g.
name: meter_file
meters:
- "*"
publishers:
- file:///var/test?max_bytes=10000000&backup_count=5&format=csv
let me know your feedback,
I think these would be valuable addons to the Ceilometer File Publisher,
Greg.
