Splunk provides SIEM, log management, and observability software.
Splunk is an enterprise machine-data platform known for powerful log indexing, search, and analytics spanning IT operations, observability, and security (SIEM). Log Observer Connect brings Splunk Cloud or Splunk Enterprise logs into an observability workflow for fast, in-context troubleshooting. Now a Cisco company, Splunk offers both ingest-based and workload (compute) pricing and can run as Splunk Cloud or self-hosted Splunk Enterprise.
Amazon CloudWatch is AWS's native observability service for collecting logs, metrics, traces, and alarms across AWS and hybrid environments. CloudWatch Logs ingests and stores log data with up to 15 months of retention, and in 2026 the service added native OpenTelemetry (OTLP) metric ingestion with PromQL querying. Combined with Application Signals and AWS X-Ray, it provides application performance monitoring for cloud-native workloads, delivered as part of the AWS platform.
Chronosphere Log Management ChronosphereChronosphere is a cloud-native observability platform built for controlling the cost and volume of telemetry at large scale. Created by former Uber engineers behind the M3 metrics project, it spans metrics, traces, and logs, and pairs log management with a Telemetry Pipeline (based on Fluent Bit / Calyptia) that shapes and reduces data before it is stored. The product is a proprietary SaaS offering aimed at large enterprises and high-volume cloud-native environments rather than a self-hosted or open-source tool.
Better Stack Better StackBetter Stack is an OpenTelemetry-native log management and observability product that bundles log aggregation (Logtail), uptime monitoring, and incident response in one platform. It emphasizes fast setup and low cost, using a collector that can instrument Kubernetes via eBPF to gather logs, metrics, and traces. It is delivered as SaaS and targets teams that want full-stack visibility and on-call workflows without enterprise-grade pricing.
