Store the system logs in MariaDB

I’ve used Elasticsearch on OpenBSD to store my system logs for quite long now. And if it does the job, there are a few things I don’t like so much with it.

I only used a single instance so I was warned about availability. But a sudden power outage had severe impact on my daily data. Way much more than what I expected from a Production-ready software. Rebuilding and re-indexing the data was a real pain in the ass. From time to time, I also get errors about indexing that seem to go away without doing nothing.

The latter is probably due to my low memory server. But I want to store logs for only a couple of boxes. And I don’t want to reserve 4GB of RAM just for this. This “gimme more RAM” manner really annoys me. And as I also need RAM for Logstash (to parse the data and send them to Elasticsearch), this leads to way too much resources consumption.

That said, I decided to test another way for storing the logs : using a RDBMS, namely MariaDB. I already have one running smooth. And I read Grafana was able to read data from it using SQL commands.

OAMP – Apache using FastCGI Process Manager on OpenBSD

Once upon a time, there was a way to run PHP with Apache on OpenBSD using the php-*-ap2 package. At that time, OpenBSD shipped with home-patched Apache 1.3 and provided Apache 2.x as a package. Since then, Apache 1.x was dropped from base, replaced with httpd(8) and ports gave the opportunity to run either Apache 1.x or Apache 2.x. This is when PHP packages and Apache 2.x became quite a pain in the ass to use. Thanks to the ports, one could deal with it. But binary PHP packages are not built this way. One way to get PHP and Apache is to use FastCGI. Here’s how to run the OAMP 6.0.
