  • 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).



  • Pixel 8 Pro is going to be my next phone.

    My Pixel 4 was amazing, switched to the Pixel 6 Pro 2 years ago and never really fell in love with the phone. Not a fan of the rounded screen edges, and in the past few months I’ve had mobile data issues with the phone. Phone shows I have decent 5G or LTE signal, but data doesn’t seem to work.

    Was with a friend one time when this happened, they’re on the same carrier as me but have a Samsung. Both of our phones showed the same 5G signal strength. They were able to playback YouTube and browse the web with no issues, but my phone wasn’t doing anything. Pages timed out, and YouTube failed to load.

    I replaced the SIM card and that didn’t fix it. Then I activated an eSIM and still having the same issue. The only “fix” I have found is putting the phone into Airplane mode for 10-20 seconds. After disabling Airplane mode the phone works properly again for a while. Wifi works fine.


  • Not arguing your point, because flash storage is so cheap now, but honestly why do people need so much local storage on their phones?

    I’ve got a Pixel 6 Pro with 128GB, and I’ve never come close to filling it in the 2 years I’ve had the phone. That’s with offline maps, YouTube downloads, Spotify downloads, tons of photos and videos. My local storage is less than 50% full still.

    I’m genuinely curious as to what people are storing on their phones that is requiring them to have more than 128GB of local storage.
