As such, we provide integrations for both Kubernetes and Docker based on Fluentd. It is a mature project that’s been widely adopted in the Kubernetes community (which replaced the ELK with EFK). We at Logz.io found Fluentd to be a good OSS for sending log data. You can read more about Fluentd and Fluent Bit here. Fluentd also recently added capabilities for service metric data. The Fluentd-Fluent Bit relationship somewhat resembles that of logstash-filebeat pair. Fluentd is more flexible, with hundreds of plugins and the ability to aggregate multiple sources, while Fluent Bit is more performant but limited in functionality and focused more on log collection and forwarding. Luckily the open source community has a rich and vibrant ecosystem of shippers for telemetry: Log Collection and Aggregation Open Source Alternatives to Filebeatįor log data there are Fluentd and Fluent Bit. We feel we can no longer wholeheartedly recommend Filebeat shipper for logs. But we cannot ignore the risk for our users. If you’re a Logz.io customer using Filebeat, then rest assured that the service keeps working even with Filebeat 7.13. Source: GitHubĪt Logz.io, we’ve started moving away from Logstash and Metricbeat already, but have kept recommending Filebeat as a good log shipper for many use cases.
Impact of filebeats license#
Logstash GitHub PR for adding license checks. In fact, Elastic carried out a similar move with Logstash recently when it pushed license checks into the open source, to ensure it sends data only to licensed Elasticsearch. I use Logstash directly without Beats, so I’m off the hook right? In this case, although it’s released as a minor version, run extensive testing, at least as you would for a major release. Typically we treat upgrades of minor versions lightly on regression testing and other checks.
Impact of filebeats upgrade#
Should you decide to upgrade to 7.13, I can give you one important piece of advice: ELK users have already begun reporting things breaking for them upon upgrade, and have understandably complained about such a change made in a minor release. Upgrade to this minor release and take the risk that things stop working, either immediately or at any point down the road. This means however that you will not be able to stay current with the latest versions to benefit from bug fixes, enhancements, security vulnerability fixes and performance improvements. Avoid Upgrades and Stay BehindĪvoid upgrades and stick with older versions of Beats (pre-7.13) to ensure that your logs and data keep flowing freely. In plain English this means that if you work with older versions of Elasticsearch or with other distros that aren’t “officially supported”, you’re now faced with one of two options: 1. Instead, I’d like to talk about what it means to you, to the user community: I don’t want to get into the politics of the vendor move, the ethics of open source or the choice to insert such a breaking change in a minor release (there’s enough chatter on that over Twitter). What Does this Breaking Change to Beats Mean? This specifically breaks open source technologies including previously open source Elastic solutions, forcing users to upgrade or downgrade different components. As a result, they have introduced this breaking change that checks for an Elastic licensed product. This causes challenges for other projects which are using these open source technologies or integrating with them.īecause of this, from their perspective Elastic finds it challenging to support these other technologies from a compatibility perspective. Elastic, however, has been more liberal with introducing breaking changes. We avoid these at all costs to prevent problems for those integrating open source to other technologies. Embedded within the Beats 7.13 minor release that was published over the weekend, a release note advised of a breaking change in which “Beats may not be sending data to some distributions of Elasticsearch”.īreaking changes are not to be taken mildly in many open source projects. If you weren’t watching closely this might have slipped under your radar. Elasticsearch 7.10 or earlier open source distros.Last week started locking down its Beats OSS shippers such that they will not be able to send data to:
