It’s a loot bug from Lethal Company.
Windows 2000 says hi to Windows 98
All the time!
I’ve woken up smacking myself thinking a spider is crawling on me, and then spend the next 20 minutes trying to convince myself that there’s no spider and its safe to fall asleep again.
Haha!
Totally had me. Excellent shitpost.
Update the OS and all installed applications using a single command.
Is this how you partition a hard drive?
This.
I just went from Arch to Debian 12 Bookworm. Running the stable branch, but so far most of the packages are rather recent. Kernel is 6.1 instead of 6.4, but I could switch to the Testing or Unstable branch to get the “bleeding edge” packages/kernels if I need to. But honestly so far it’s been a real pleasure to use. Everything is just working and is stable.
Not saying you have to or anything, and I can understand and respect using something like MX Linux to save time on the customization. Just know that because it’s based on Debian, any core OS updates will be delayed while the MX team rebases them into their fork.
Honest question, but why not just install Debian with the Xfce DE? Why rely on a fork for updates?
From what I can tell both by testing MX Linux and by reading about it, it’s nothing more than Debian with a few pre-installed packages and some customization. All of which could be done on Debian directly without much trouble.
Zabbix stores all it’s data in a PostgreSQL or MySQL database. However… there are 2 ways that Zabbix Agents work. Either in passive mode, or in active mode.
Passive Agent = “poller” process on the Zabbix server sends a request to the agent asking for values for the items it’s monitoring (based on template applied to host). Depending on the number of hosts you’re monitoring and how many poller processes are configured to start with the Zabbix server, you may run into a situation where requests are queued because the poller process is too busy. Increasing the number of poller processes will fix this, but it also adds additional load to your DB as each poller process will connect to your DB to write data, and each poller process will consume a certain amount of memory. Too many and you’ll run out of RAM, or bog down your DB.
Active Agent = “trapper” process on the Zabbix server listens for item values from being sent to it from the agents. Agents will query the Zabbix server to see what templates are applied to it’s host, and will figure out what items it’s supposed to monitor. The agent will actively query the items without the Zabbix server requesting it, and will send the item values to the server as scheduled. This puts a lot less load on the Zabbix server.
Item values are not read from the DB to activate the trigger. When a value is received that matches the trigger’s expression, then the trigger is activated. Live values are used to activate triggers and trigger actions (alerts).
That’s for everything listed above. This is measured straight from my UPS which everything is connected to.
