<p class="MsoNormal">Hi!<o:p></o:p></p>

<p class="MsoNormal"><span lang="EN-US">I’m running the same binary concurrently with different options using timers and instances, and I have the problem that it’s not obvious which instance logged an error.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">Like this:<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">Now my obvious problem is: “Which instance created PID 15985?”<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I could use “SyslogIdentifier=” to set the identifier to “unit@instance”, but I’d rather like to append some string (to get something like “check@instance[pid]” or “check[pid]@instance”), but then I would need the original
identifier in some variable.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">However variables are only set at the “unit level”, so there are no special variables from the “exec level”.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">When setting the value to a fixed string, I will have a problem when running more then one process, obviously.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Are there any solutions to this?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Kind regards,<o:p></o:p></span></p>
