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.
