eMQTT-Bench 工具发布消息

EMQX 性能问题

利用 eMQTT-Bench 工具发布消息，发现支持-m 指定发布的消息内容，请问如何时%TIMESTAMPMS%。
-m, --message Set the message content for publish. Either a literal message content,
or path to a file with payload template specified via
‘template://<file_path>’. Available variables: %TIMESTAMP%,
%TIMESTAMPMS%, %TIMESTAMPUS%, %TIMESTAMPNS%, %UNIQUE%, %RANDOM%. When
using ‘template://’, --size option does not have effect except for when
%RANDOM% placeholder is used.

./emqtt_bench pub -h {EMQX_IP} -p 1883 -t “test/qos0” -q 0 -c 10 -I 1000 -m “{"ts":%TIMESTAMP%}” 中占位符无法生效
