In their own words
OpenNMS
OpenNMS is an open-source platform for monitoring faults, performance, traffic, and alarms across local and distributed networks. Horizon is the free community distribution with the newest features; Meridian is the stable subscription version. Data collection supports SNMP, JSON, WinRM, XML, SQL, JMX, SFTP, FTP, JDBC, HTTP, HTTPS, VMware, WS-Management, and Prometheus. Traffic monitoring handles NetFlow v.5/9, IPFIX, and sFlow, with stated capacity above 300,000 flows per second. Minions extend monitoring to remote devices and services, including locations behind firewalls or NAT through ActiveMQ or Apache Kafka. Integrations include email, Slack, Mattermost, scripts or webhooks, Jira, Remedy, TSRM, Grafana, and a REST API. Grafana views can show alarms, outages, KPIs, NetFlow, and data from multiple instances. The software supports API, Linux, self-hosted, and web deployments. Horizon is free; Meridian plans range from $6,000 a year to $66,000 a year, with larger deployments priced on request.
PagerDuty
PagerDuty manages incidents from detection through resolution using automation and real-time collaboration. Its AIOps tools are described as reducing alerts, automating repetitive tasks, and accelerating resolution, while PagerDuty Automation standardizes workflows across people, tools, and systems. Teams can use on-call scheduling, escalation policies, stakeholder updates, ChatOps incident actions, and post-incident reviews. PagerDuty lists more than 750 integrations, with connections through email, API, or MCP; examples include AWS, Slack, Anthropic Claude Connector, Microsoft Teams, Cursor, and Datadog. Its iOS and Android apps support incident response, schedules and overrides, incident context, and automated response tasks, but require a PagerDuty account. The free Incident Management plan covers up to five users, one on-call schedule, and one escalation policy. Paid incident management starts at $21 per user per month with annual billing, and a 14-day trial is listed. PagerDuty says it serves developers, reliability engineers, customer success, security, and C-suite teams. It reports SOC 2 Type II examinations and ISO 27001 certification for its services.
