Description

I like to set sysctl variables through a technique and created therefore the attached technique (exported file attached).

This technique has to parameters: "var_name" and "var_val".
I use "File key-value present" to set this ke/vakue in /etc/sysctl.conf
and on the condition that this was repaired I use "Command execution"
to execute /sbin/sysctl -p

If I now apply this technique several times (with several directives, using each time another key/value pair)
all but the first command execution return a Messages --> "Missing" in version 6.0.4

I had the exact same technique in 5.0.15 and there it worked (all green)

Upgrading to critical since it's a regression (and we missed it, sorry Tim)

Hi Tim,

Do you know that we have a generic method sysctl exactly for this use case?

Cause of the issue here is that the command is the same for all directives, with exact same value, so it is executed only once, and then skipped (agent don't execute twice the same command :( )
Workaround: add a comment after the sysctl -p
like

sysctl -p # reload for variable ${var_name}

Hi Tim,

Could you try to use sysctl generic method for this use case?
