Web client active session

[mxav1111]

Hi there,
I am trying to automate a certificate renewal and looking for way to avoid user disruption if possible when certificate expires.
Is there a way to identify if web client is/was active in last N (let's 30 or so ) mins? If so, we can wait out a bit before bouncing.
Any thoughts or ideas? Or a way to force renewal without bounce that will be taken up by next web client connection?

maybe you check the lqst time q metric hws been updated? This is the way I would do it.

Thank you. Please can you give more details on command - file - string to look for?

Is this how really it works? Everyone with free certs has to bounce every three months? That sounds so unreasonable :-(.
