We have spent over 2 years building OpenObserve into a simple, highly usable and efficient observability tool. You could run it using a single binary that provides all the functionality of logs, metrics, traces, front end monitoring, dashboards (18 different chart types), alerts and pipelines.
OpenObserve is being used by startups, mid tier enterprises and fortune 100 companies. There are thousands of active installations of OpenObserve globally.
Folks have replaced Elasticsearch, Splunk, Graylog, Datadog , Newrelic and more for OpenObserve.
Comment from a user -
We moved from 5 node OpenSearch cluster to single node OpenObserve and measured using our actual everyday queries, which are reasonably complex queries (1 to 5 conditions applied) over our real logging data. We see that typically they complete in about the same time. OpenObserve costs us 10 times less though (instances + storage)
Also, we are currently working on replacing one of the world's largest splunk installations.
p.s. I am one of the maintainers of OpenObserve. Feel free to ask questions. I will be happy to answer them. You can also visit our slack workspace at https://short.openobserve.ai/community for discussions.
