got this in my rsysconf:

    $template TemplateLog,"%msg%\n"   
    $template DynamicLog,"%msg%\n"                                                                                                                            
    $template DynamicFile,"/var/log/%PROGRAMNAME%.log"    
    if ($programname == "test") then {local3.=debug    -/var/log/path.log;TemplateLog}                                                                  
    local3.=debug    -?DynamicFile;DynamicLog                                                                                                                 
    & stop

If I put away the if statement, it works well. But I need to make the if statement working. What is wrong about it? Thank you for advice.

I tried to change the == to contains as suggested in one of answers, this does not help.

Is $programname containing same info as %PROGRAMNAME% ? This could cause the problem, maybe...

So acording to answer, I have made this:

$template TemplateLog,"%msg%\n"   
$template DynamicLog,"%msg%\n"                                                                                                                            
$template DynamicFile,"/var/log/%PROGRAMNAME%.log"           
template(name="pname" type="string" string="%PROGRAMNAME%")                                                                                               
set $!xyz = exec_template("pname");     
if ($!xyz contains'test') then {local3.=debug    -/var/log/path.log;TemplateLog}
local3.=debug    -?DynamicFile;DynamicLog                                                                                                                 
& stop

But unfortunately, this code is not working either. If I delete the if statement, the second DynamicFile is saved into test.log, so the value is correct.

You can always print the variable to see the output. I think is something related to syntax, please try using contains instead of ==.

You can assign it to a var using templates:

    $template DynamicLog,"%msg%\n"                                                                                                                            
    $template DynamicFile,"/var/log/%PROGRAMNAME%.log"    
    template(name="pname" type="string" string="%PROGRAMNAME%")
    set $!xyz = exec_template("pname");
    if ($!xyz contains 'test') then {local3.=debug    -/var/log/path.log;TemplateLog}                                                                 
    local3.=debug    -?DynamicFile;DynamicLog                                                                                                                 
    & stop```

No, this is not helping. Im almost sure it is something with syntax, cant see it tho, as Im really not into this

How do you print it tho?

Ok, so ```$programname``` and ```%PROGRAMNAME%``` are not the same, you can't just use "programname" as var.

So probably the ```if``` syntax is ok, but you can do it with template (I will edit my answer)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
