FILEBEATS VS LOGSTASH CODE

It even can survive short outages of the ES itself I think (should check that).It will run in its own pace, so even if process goes down, the messages produced by this process will be written to the ES after all.

filebeat is much more “humble” when it comes to the resource consumption, and if you have like many instances to log (really distributed logging, that I’ve assumed you have anyway) consider putting a service of filebeat (deamon set if you have k8s) on each node from which you’ll gather the logs, so that a single filebeat process could handle different instances, and then deploy a cluster of instances of logstash on a separate machine so that they’ll do a heavy log-crunching all the time and stream the data to the ES.

logstash is way heavier than filebeat from the resource consumption standpoint, and usually you should parse the log message (usually with grok filter) in logstash.

Yet another issue – what happens if you want to “rotate” the indexes in the ES, namely create an index with TTL and produce a new index every day.įilebeat/logstash potentially can solve all these issues, however they might require a more complicated setup.īesides, obviously you’ll have more services to deploy and maintain: One more “technicality” – what happens if the application gets restarted for some reason, will you be able to write all the logs prior to the restart if everything gets logged in the advice?

FILEBEATS VS LOGSTASH CODE

In addition you won’t be able to write “in batch” into the elasticsearch without the custom code and instead will have to create an “insert” per log message that might be wasty. When you log in the advice – you will “eat” the resources of your JVM – memory, CPU to maintain ES connections pool, thread pool for doing an actual log (otherwise the business flow might slow down because of logging the requests to ES). I think you better off with filebeat / logstash or even both to write to ES, here is why: If I compare the first and the second option that you’ve presented, This approach solves issues that might appear in the “first” option that you’ve presented, while some other issues will be left unsolved. Technically both ways can be implemented, although for the first path I would suggest a different approach, at least I did something similar ~ 5 years ago in one of my projects:Ĭreate a custom log appender that throws everything into some queue (for async processing) and from that took an Apache Flume project that can write stuff to the DB of your choice in a transaction manner with batch support, “all-or-nothing” semantics, etc. I also assume that you have quite a log of logs to manage, otherwise, if you’re planning to log like a couple of messages in a hour, then it doesn’t really matter which way you go – both will do the job. Log every request and response into a log file and using filebeat and/or logstash to send them to ElasticSearch.įirst off, I assume, that you have a distributed application, otherwise just write your stuff in a log file and that’s it Using Spring Boot ResponseBodyAdvice to log every request and response that is sent to the client directly to ElasticSearch. Which of the following two methods has better performance?
