SavaMoni.（サバモニ） is a server monitoring SaaS provided by NETASSIST Inc. It emphasizes quick setup: you can create an account with just an email address, then configure monitoring targets, services, and notification destinations after logging in. The site says you can go from account creation to active monitoring in about 3 minutes, and it offers a 30-day free trial.
Its features cover basic infrastructure monitoring: Ping availability checks, port and service monitoring for FTP/SSH/SMTP/HTTP/POP/IMAP/HTTPS/NTP/DNS, web page string checks, and Agent-based performance monitoring. The Agent can collect CPU usage, free memory, swap, disk, and inbound/outbound traffic; on Linux, it also supports Load Average. Alert channels include email, automated voice calls, and Webhook, with Slack notifications available via Webhook. It also supports a Web API, allowing monitoring registration to be incorporated into configuration management or server provisioning automation workflows. The admin console supports mobile and tablet browsers, and provides two-factor authentication, six months of alert history, and operation history.
External service monitoring is not tied to a specific server OS as long as the target is reachable from the internet. The text mentions CentOS, RHEL, Ubuntu, Windows Server, and macOS Server. Agent monitoring has environment restrictions and requires users to install and configure the Agent on their servers; the exact supported environments should be checked on the relevant page or in the documentation after login. In terms of ecosystem, it mainly centers on Slack/Webhook integration, the Web API, and NETASSIST’s MSP services. There is no visible information about SDKs or a plugin marketplace.
Pricing is straightforward: 550 JPY/month per server, tax included. The trial lasts 30 days and supports up to 5 servers. Phone notifications are billed at 88 JPY/minute. The service does not automatically charge you after the trial ends; to continue using it, you need to register a credit card. Supported cards include VISA, Mastercard, JCB, and American Express. For support, basic inquiries are handled via messages/email through the admin interface, with no phone support provided. More advanced needs such as first response, root-cause investigation, cloud migration, and managed security updates require consulting NETASSIST’s staffed MSP service.
The advantages are low cost, simple configuration, a complete set of basic monitoring items, and coverage of both external monitoring and host performance metrics. Webhook/API support also makes it friendly to automated operations workflows. The limitations are that public information does not fully explain details such as SLA or monitoring intervals, Agent monitoring depends on manual deployment, and the terms of service restrict eligibility to corporations in Japan or adult residents of Japan, making it clearly oriented toward the Japanese market. It is suitable for local Japanese SMEs, website administrators, and lightweight operations teams. If you need global monitoring nodes, complex APM, or deep log analytics, consider Datadog, New Relic, Better Stack, Zabbix/Prometheus; China-based teams may also compare Alibaba Cloud CloudMonitor and Tencent Cloud Observability Platform.
The main text does not provide information on availability from mainland China, so this remains unknown. Payment options only list international credit cards, with no information about Alipay, WeChat Pay, or RMB billing. Together with the eligibility restrictions, direct procurement from mainland China may involve compliance and payment barriers.
