私はrsyslogを使ってリモートのLogstashサーバーにログを送信しています。そのサービスのLogstashは入力データをjson形式で受け取る予定です。 rsyslogテンプレートをjsonに設定するにはどうすればよいですか？たとえば、次の例外を1つのメッセージとして送信したいとします。リモートログの例外エラーのrsyslogテンプレートを設定するにはどうすればよいですか？

次のrsyslog構成ファイルがあります。 startmsg.regexは、新しいメッセージが "YYYY-mm-dd"の日付形式になったときに、そのメッセージの開始を「フラッグ」することを目指し、その形式を見るまで、現在の日付形式の後に続くテキストメッセージ。
input(type="imfile"
File="/usr/share/tomcat/dist/logs/trm-error.log*"
Facility="local3"
Tag="trm-error:"
Severity="error"
startmsg.regex="^[[:digit:]]{4}-[[:digit:]]{2}-[[:digit:]]{2}"
escapeLF="on"
)
if $programname == 'trm-error:' then {
action(
type="omfwd"
Target="10.53.234.234"
Port="5514"
Protocol="udp"
template="textLogTemplate"
)
stop
}
と以下のテンプレート。
# Template for non json logs, just sends the message wholesale with extra
# # furniture.
template(name="textLogTemplate" type="list") {
constant(value="{ ")
constant(value="\"type\":\"")
property(name="programname")
constant(value="\", ")
constant(value="\"host\":\"")
property(name="hostname")
constant(value="\", ")
constant(value="\"timestamp\":\"")
property(name="timestamp" dateFormat="rfc3339")
constant(value="\", ")
constant(value="\"@version\":\"1\", ")
constant(value="\"customer\":\"customer\", ")
constant(value="\"role\":\"app2\", ")
constant(value="\"sourcefile\":\"")
property(name="$!metadata!filename")
constant(value="\", ")
constant(value="\"message\":\"")
property(name="rawmsg" format="json")
constant(value="\"}\n")
}
しかし、Logstashは、JSONファイルとしてログを解析しようとする「JSONParseErrorを」文句を言います。すべての手がかりは？
