What is a good solution for centralizing lots of log files for monitoring and analysis?
I have about 20 Linux web servers generating ~4GB of nginx and Apache log files per day. I would like at least 30 days of logs to be retained.
I have used Sumo Logic in the past, and moved to a self hosted ELK stack, which is unfortunately no longer functioning. I am looking for a solution that will have similar analysis abilities to Kibana, and at a competitive price.
If the solution also monitors Metrics for a set of servers (i.e. CPU/Memory/Disk usage) that would be great, but I am ok with setting that up separately using Munin / NetData to save money. My main requirement is to get a good value for money tool for log file analysis.
