Centralized log-management-with-elastic-stack
Centralized log-management-with-elastic-stackRich Lee Centralized log management is implemented using the Elastic Stack including Filebeat, Logstash, Elasticsearch, and Kibana. Filebeat ships logs to Logstash which transforms and indexes the data into Elasticsearch. Logs can then be queried and visualized in Kibana. For large volumes of logs, Kafka may be used as a buffer between the shipper and indexer. Backups are performed using Elasticsearch snapshots to a shared file system or cloud storage. Logs are indexed into time-based indices and a cron job deletes old indices to control storage usage.

- 26. Marathon • Streamsets instances running in docker containers in Marathon o Easy deployment and scaling o Fast upgrade to newer version • Issues we faced with this approach: o Containers were killed by marathon o Needed to re-import pipeline every time we launch container
- 27. Marathon • Working with Streamsets trying to resolve the OOM issue we increased container memory and SDC heap size • At first, all looked normal and we thought that it was just starving on resources, but several days later we had SDC killed again • We increased MEM and HEAP even more – to 16G, but we bought just another day or two before is was killed again • Looked like SDC heap were constantly filling with data that don’t go away and eventually it kills the container • Also GC was working hard and sometimes we got freezes up to 60 seconds • Decided to move out from Docker
- 28. Marathon • Streamsets reading JSON messages from Kafka cluster and output to Elasticsearch cluster o De-serializing and serializing JSON was very slow with single threaded process o Consuming from Kafka performance test showed: JSON format: 5k records/sec avg Text format: 50k records/sec avg Binary format: 250k records/sec avg • Streamsets team were very proactive with this issues and in 2 days we received a fix for multi-threaded JSON parsing o New testing showed: JSON format: 66k records/sec avg
- 29. Marathon • Streamsets has never failed because of any internal logic bugs but we kept seeing this oom-killer popping up and recovering was not automated • We decided to leave docker and run SDC natively on host, still using Marathon for scaling and failover • Without docker, we now can upload our pipeline on SDC startup, and it will start working as soon as instance has loaded We can freely scale up/down whenever we need Also, we got rid of oom-killer issue as well
- 30. Each one of our 3 SDC instances already processes ~3B messages, with no issues!
- 31. • Streamsets pipeline consume metrics gathered by collectd and logs gathered by logstash from 4 different clusters (including self), transform and decorate them and send to Elasticsearch for storage and analytics. • First of all we consume messages from Kafka topic at average of 5,000 messages per second. The consumer itself parses JSON-format and sends further. • Next stage is a JavaScript script that decorates messages with cluster name, based on a instance hostname in that message • Finally, we exclude Marathon events from stream sending them directly to ES
- 32. • Next stage will splits stream into 2 parts: logs and metrics • Metrics are send straight to ES without any transformation • Logs are the most interesting part: o We pop docker container logs from stream and delete “time” field that’s duplicate timstamp and sending them to ES o We separate logs from specific clusters, because we need to apply special logic for them o Separation is done though mapping IP’s to clusters in the pipeline realtime
- 33. • Collecting data from several Mesos clusters and need to correlate container metrics with it’s logs • Use appID taskID and runID to identify specific containers logs • Container logs itself have all three of this, while mesos- master and mesos-agent logs lacks runID • All unidentified data is discarded
- 34. Current ShippedAnalytics prod cluster configuration: Kafka Cluster: 7 brokers with 4CPU and 16GB RAM each Logstash topic for all incoming messages with 7 partitions and 2 replicas Current data flow is avg 5000 messages/sec to Kafka Current data size is avg 1,2MB/sec to Kafka Streamsets: 3 instances with identical pipeline configuration reading from Kafka cluster 7 partitions are split between 3 instances like 3/2/2 All 3 instances running natively on host (non-docker) with Marathon Marathon restarts failed instance with automatic pipeline upload and start Elasticsearch: 7 nodes with 4CPU, 16GB RAM and 2TB storage each Each metrics is written to its own index, total of 15 indexes Each index has 5 primary shards and 5 replica shards Total Doc count: 17,5B Total Doc size: 3.84TB 1 Day rate count: ~500M 1 Day rate size: ~120GB
- 35. Streamsets is a great product to work with, also team is super helpful and works fast • Lots of input and output connectors, huge processing capabilities • Very intuitive and rich User Interface • Easy to create pipelines visually, instead of writing code • Clear data flow paths • Small resource consumption compared to performance • Easily can handle up to 10k records/sec to Elasticsearch with 1CPU 2GB RAM • Simple configuration and deployment process • Opensource(!) • Fast logic changes with minimum downtime • Preview mode(!) – check every stage before throwing all your data it • Rich data transformation possibilities • GROK filters – easy to migrate from Logstash • Smart Errors handling • Reliable: not once did Streamets crashed by itself – only Docker, Marathon, Mesos issues
