rsyslog ommail sends messages with empty bodies

  • 772

I'm trying to send email from rsyslog (using the ommail module) on certain events, but no matter what I do the message bodies are always empty.

My configuration file says:

module(load="ommail")

template (name="mailBody"  type="string" string="RSYSLOG Alert\\r\\nmsg='%msg%'")
template (name="mailSubject" type="string" string="lti problem on %hostname%")

if $syslogseverity <= 4 and $syslogfacility-text == 'local1' then {
   action(type="ommail" server="localhost" port="25"
          mailfrom="[email protected]"
          mailto="[email protected]"
          subject.template="mailSubject")
}

This is copied from the example at https://www.rsyslog.com/doc/v8-stable/configuration/modules/ommail.html

Messages are sent but the body is empty. How do I fix this?

  1. Try this one:

    module(load="ommail")

template (name="mailBody"  type="string" string="%msg%")
template (name="mailSubject" type="string" string="lti problem on %hostname%")

if $syslogseverity <= 4 and $syslogfacility-text == 'local1' then {
   action(type="ommail" server="localhost" port="25"
          mailfrom="[email protected]"
          mailto="[email protected]"
          subject.template="mailSubject"
          body.enable="on"
          template="mailBody")
}

    See the mailBody template value %msg% and the parameters body.enable="on" and template="mailBody".

  2. You must specifically set the template on the action clause (with template="mailBody"). This is missing from the example. You may also need body.enable="on" though this is supposedly the default. 

    module(load="ommail")

template (name="mailBody"  type="string" string="RSYSLOG Alert\\r\\nmsg='%msg%'")
template (name="mailSubject" type="string" string="lti problem on %hostname%")

if $syslogseverity <= 4 and $syslogfacility-text == 'local1' then {
   action(type="ommail" server="localhost" port="25"
          mailfrom="[email protected]"
          mailto="[email protected]"
          subject.template="mailSubject"
          template="mailBody")
}
