Sensu Go
Sensu Go is a commercial monitoring and observability solution for enterprise DevOps and SRE teams overseeing infrastructure from Kubernetes to bare metal. It collects, filters, and transforms monitoring events before sending them to a database chosen by the customer. Teams can manage declarative monitoring configuration, check system and service health, collect metrics and logs, and run custom scripts including Nagios-style plugins. Agents discover virtual machines, public cloud compute instances, containers, and services. Sensu can alert by email, Slack, or SMS, create or resolve incidents in PagerDuty, ServiceNow, and JIRA, and deduplicate alerts. It also supports remediation actions such as restarting services or running scripts. Sensu Go is self-hosted and free for up to 100 nodes at one site. Pro costs $36 per year, billed annually, with a 100-node minimum; this equals $3.00 per node/month when billed annually. The free 14-day trial is for evaluating beyond 100 nodes. The backend is unsupported on Windows and macOS.
