1. Identify the Cause of High Disk IO and CPU Wait MariaDB Activity: Since mariadb is showing high IO during the problematic window, it's crucial to identify the queries causing this load. You can enable the slow query log in MariaDB to capture queries that are taking an unusually long time to execute. Scheduled Tasks: Check for any scheduled tasks (cron jobs) on the server that run around 5 AM CST. These could be system tasks, WordPress cron jobs, or database maintenance tasks. 2. Systemd-journald Failure The failure of systemd-journal-flush.service suggests that the journaling system is overwhelmed, likely due to the high IO load. Investigate the journal logs (journalctl) for any errors or warnings that occur around this time. 3. Review WordPress Plugins and Activities Plugin Behavior: Even though plugins like Updraft Plus are scheduled for different times, they might be triggering background tasks. Verify plugin behavior and logs. WordPress Cron: WordPress has its own cron system (wp-cron.php) that can sometimes trigger resource-intensive tasks. Review the WordPress cron events. 4. Server and Database Optimization Database Optimization: Run a check and optimization task on your MariaDB database. Over time, databases can become inefficient and slow. Upgrade Resources: An e2-micro instance is quite limited in resources. If this issue is related to resource constraints, consider upgrading the VM instance type. 5. Monitoring and Logs Enable Enhanced Monitoring: Tools like sar, iotop, or atop can provide in-depth system metrics. Make sure they are configured correctly. Access and Error Logs: Review NGINX, PHP-FPM, and MariaDB logs for any anomalies during the problematic time frame. 6. External Factors Traffic Spikes: Although Jetpack stats show low traffic, consider checking the access logs for unexpected traffic spikes, which might be bots or crawlers. Network Analysis: Use tools to monitor network activity. Unexpected external connections might be contributing to the load. 7. Testing and Isolation Isolate Components: Temporarily disable certain components or plugins during the problem window to see if the issue persists. Test in a Staging Environment: If possible, replicate the setup in a staging environment to test without affecting the live site.

@networknerd I wanna attend but I've got my salsa dance class at that time 😞

For anyone who missing the live event, you can find the recording here - https://www.youtube.com/watch?v=RJjVInQuIbg. It's 2 hours of really good information.

Maybe we will see you next time, @scottalanmiller. I hope all is well!

We're still a green light for this event. Join us if you can for stories of job change during the pandemic, and bring your questions.

My MeshCentral VM is in Vultr.

Same here. Way better than AWS, Azure, or GCP for standard workloads like this.

Just for home use, it could likely sit in a free AWS Lightsail instance if it is small enough.

After way too much time spent on this, we found the problem is twofold. Hopefully this will help someone else in a similar situation.

In the Lumens, to get it to recognize a new stream key for Facebook, we had to put in some random text characters in the stream key field, save the changes, paste the new stream key, and save the changes. That would generate the preview and allow streaming to Facebook no problem.

We found there was a greater issue present. The internet speed at the building where the encoder sits was supposed to be 100 / 7, but they were not getting anything close to that. Once we got Facebook working in addition to YouTube, we found streaming both caused them to be extremely choppy.

After having an ISP technician out to the building last week, they said the wiring in the box outside the building was awful, we were at the end of the line, and that he was surprised we ever got internet signal to the building. They are working on clearing up the pipe now so the signal is strong and clean, and we're upgrading to 200 / 10 pretty soon. We also changed the video resolution we're sending to YouTube and Facebook so we're using a lot less bandwidth to ensure we don't use the entire upload pipe.

There's still time to join in the fun before 9/22.

I have a meeting that I can't miss. 😞

I've been pretty satisfied with Azure DevOps so far, but calling it 'Azure' seems to be a marketing move and ends up being a misnomer.

I love the fact that Azure can advertise giving customers DevOps for free.

Haha, MS clients can now say their company has adopted DevOps.

Reminds me of them commandeering Office and SQL.

Don't forget DOS!

Pretty cool. I’ll have to try it and see how it goes.

I’ve been using Unbound for several years running on a Raspberry Pi and using a custom black list. Love not having to run ad blockers on each computer browser since it’s all taken care of with Unbound.

@NetworkNerd Your quadratic formula is wrong and most of those aren't functions, but nice effort I suppose:)

@NetworkNerd Are either of these able to be remote?

But the biggest benefit is getting to move to Dallas!

While that would be a bonus for me, I have a fiance and new mother in law that it wouldn't go over well with 😕

Sorry couldn't make it dealing with family/kids issues last night.
