Help with notifications on events like player disconnects

[SmutsMuts]

There is an example for how to make a notification when a player spawns in a server, are there any other fun examples of notifications I can get some help in making?
I would like to have a notification when someone disconnects from the server.
I would like to have a notification when someone dies.
I would like to have a notification when an event like trolls attacking or similar is happening in the game.
Could someone help me with this?

What I was refering to earlier was:
-e DISCORD_WEBHOOK="https://discord.com/api/webhooks/8171522530..." \
-e VALHEIM_LOG_FILTER_CONTAINS_Spawned="Got character ZDOID from" \
-e ON_VALHEIM_LOG_FILTER_CONTAINS_Spawned='{ read l; l=${l//*ZDOID from /}; l=${l// :*/}; msg="Player $l spawned into the world"; curl -sfSL -X POST -H "Content-Type: application/json" -d "{\"username\":\"Valheim\",\"content\":\"$msg\"}" "$DISCORD_WEBHOOK"; }'

Any hints here what to do? I am also interested in sending a message to Discord when a player disconnects.

I had to use regex to get it to work

VALHEIM_LOG_FILTER_REGEXP_Spawned=\bGot character ZDOID from \b\w*\b : [^0]\d*\b:2\b
ON_VALHEIM_LOG_FILTER_REGEXP_Spawned={ read l; l=${l//ZDOID from /}; l=${l// :/}; msg="Player $l is online!"; curl -sfSL -X POST -H "Content-Type: application/json" -d "{"username":"Valheim","content":"$msg"}" "$DISCORD_WEBHOOK"; }

VALHEIM_LOG_FILTER_REGEXP_Death=\bGot character ZDOID from \b\w*\b : 0:0
ON_VALHEIM_LOG_FILTER_REGEXP_Death={ read l; l=${l//ZDOID from /}; l=${l// :/}; msg="$l just died!"; curl -sfSL -X POST -H "Content-Type: application/json" -d "{"username":"Valheim","content":"$msg"}" "$DISCORD_WEBHOOK"; }

VALHEIM_LOG_FILTER_CONTAINS_RandomEvent=Random event
ON_VALHEIM_LOG_FILTER_CONTAINS_RandomEvent={ read l; l=${l//event set: /}; l=${l// :/}; msg="Random event: $l"; curl -sfSL -X POST -H "Content-Type: application/json" -d "{"username":"Valheim","content":"$msg"}" "$DISCORD_WEBHOOK"; }

I was only able to map a Logoff event from pushing the ZDOID (the \d+:\d+ in the Got character ZDOID from, as long as that ZDOID isn't 0:0 - which TIL is "character died" ;) ) onto a stack, and then when you get a Destroying abandoned non persistent zdo event with that matching ZDOID (whatever you want to call it). Which means you can't actually parse it in a vacuum, as you need to have a running list/hash of currently logged in users mapped to their current ZDOID. At least, that's what I'd do. But that's speculation and it kind of works. I don't push that event to a Discord server, though. That's too hard.
