How can I filter out all veth* interfaces.

[soichih]

Is there a way to hide interfaces that starts with "veth"? My graphite DB is filling up with tons of metrics from this plugin, and I'd like to filter them out if possible.

$ ./metrics-netif.rb

Until this issue is resolved you can do following

1. add following line

^PREFIX\..*\.if\.veth.*

into /etc/carbon/blacklist.conf

2. add

USE_WHITELIST = true

into /etc/carbon/carbon.conf

3. restart carbon

notes:

• files location can differ based on your GRAPHITE_CONF_DIR
• construct regex for blacklist to match your needs
