What Sysmos is
Sysmos combines distributed API health checks, Linux server observability, and a centralized monitoring dashboard. Its synthetic endpoint checks run across regions and report status, SSL, latency, and timing details for DNS, TCP, TLS handshake, server processing, and content transfer. Per-phase averages and maximums are available over one-hour, 24-hour, and seven-day periods. A flow builder chains API steps, extracts variables, and applies assertions; flows can run on demand or on a schedule. For Linux, an eBPF agent for x86_64 and arm64 captures syscall, network, CPU, and memory data. The maker states that its CPU overhead is under 2%. Alerts can go to Slack, Discord, PagerDuty, email, or HTTP endpoints through webhooks. Workspaces offer admin, developer, and viewer roles, along with API keys for CI/CD and infrastructure-as-code. Sysmos says SOC 2 is in progress and offers EU and US data residency. Its Free plan costs nothing and includes 10 monitors, five flows, one region, a 60-second minimum interval, five team members, one organization, and seven-day log retention. Team is $29 a month; Business is $99 a month.
Good
- Checks APIs across multiple regions
- Flows support variable extraction and assertions
- Linux agent captures system and network data
- Free plan includes 10 monitors and five flows
Watch out
