Run script when client is disconnected from my Hotspot

RouterOS General
1

First of all - Hi for all. It is my first post here.

I need to monitor somehow when clients leave my hotspot.
For instance:

  • i give a trial internet via my hotspot for a 1 hour
  • client connect to hotspot, log-in via Trial link
  • and surf in the internet, say, 20 minutes, then just go away, or disable the Wi-Fi on his device
  • in the moment of disconnection (maybe when client disappears from registered by my Wlan ) i need to rung some script.
    Hence i need to find out a way of how to check the disconnection moment.

Hope someone may help me. If i have described my goal not so clear, please say that, i will rephrase it.
Thank you mikrotick community in advance!

I’m afraid this is not possible with routerOS onboard tools.
You could either schedule a script which parses the log every n minutes - or you add logging wireless events to a syslog server and parse there.

Thank you for such fast answer.

Some tips of how to parse logs(??)

May i do it on board or needs to sent them into external server for parsing …

Edit:
Second reading of your replay, makes me a bit clearer))

Going to write about results soon…

You can go for it in the router, this wiki article is pretty nice for the start.

Wow, nice, At first look, it is what i need…

So i have followed the article. I have:

  • created buffer in memory,
  • added a topics=wireless,info ,
  • created Log Parser Script (identical as in the wiki)
  • created Parser Action Script (there i have removed almost all if construction and edit one “:if ([:tostr $logTopics] = “wireless;info”) do={ …”)
    Tried to edit second script plenty of times, and still can’t reach the “do={…” construction.

I have went further and checked the:
:global logParseVar
:local logTime [:pick [:toarray $logParseVar] 0]
:local logTopics [:pick [:toarray $logParseVar] 1]
:local logMessage [:pick [:toarray $logParseVar] 2]

As it turned out, the :global logParseVar contains only:
jul/26/2017 ,

But why :local logTopics [:pick [:toarray $logParseVar] 1] and :local logMessage [:pick [:toarray $logParseVar] 2] are empty??
Maybe someone may help with this as well?

Also why time in the jul/26/2017 format and not in the 16:16:22 as it is in the console??

I’d suggest to open a separate post in the scripting forum - this would give you a better chance of being helped.
