■rsyslogのプライオリティ値リストを作成してみる。
$ apt-cache show rsyslog | grep Ver
Version: 8.24.0-1
■ソースのダウンロード
$ apt-get source --download-only rsyslog
$ tar zxvf rsyslog_8.24.0.orig.tar.gz
$ cd rsyslog-8.24.0/
■3ビット左シフトなので、8倍(2^3)すれば良い。
$ grep -A 33 LOG_EMERG ./runtime/rsyslog.h | awk '/LOG_/{gsub("LOG_","",$2);print $3"\t"$2}' |tr '[A-Z]' '[a-z]'
0 emerg

■ということで以下の並びとなる。
注意点としてはkernの0とemergの0を区別するために3桁になること。
$ grep -A 33 LOG_EMERG ./runtime/rsyslog.h | \
awk '/LOG_/{gsub("LOG_","",$2);print $3"\t"$2}' | \
tr '[A-Z]' '[a-z]' | sed -e 's/<<3)//' -e 's/(/_ /' | \
awk '!/24/{if($1=="_"){printf "echo \"%03d\t%s\" >> Severity.list\n",$2*8,$3} \
else{print "echo \""$1"\t"$2"\" >> Facility.list"}}' | sh
■Facilityが8種類なので計176種類の優先度が指定出来る。
$ echo -e $(wc -l Severity.list ;echo "\n";wc -l Facility.list) | awk 'BEGIN{a=1}{a=$1*a;print $0}END{print a}'

■組み合わせは176種類

awk '{print "<"$1">",$2,$3,$4,$5}' > Priority.list
■以下のように調べる。
$ awk '/local4/&&/info/' Priority.list
<166> 160 local4 6 info
$ awk '/local4/&&/info/{printf "%s %d(%d) %s %d %s\n",$1,int($2/8),$2,$3,$4,$5}' Priority.list
<166> 20(160) local4 6 info
$ grep 160 Severity.list
160 local4
$ grep 6 Facility.list
6 info
