How to recover a deleted branch
## Pre-requisite: You have to know your last commit message from your deleted branch.
git reflog
# Search for message in the list
# a901eda HEAD@{18}: commit: <last commit message>
# Now you have two options, either checkout revision or HEAD
git checkout a901eda
# Or
git checkout HEAD@{18}

buffer_size => 1452 # Should be specified. 1452 is the default for recent versions of collectd
codec => collectd { } # This will invoke the default options for the codec
type => "collectd"
}
