Xitoring

What is Xitoring? Xitoring is an all-in-one monitoring platform for servers, websites, and status pages, with AIOps built in. It replaces the typical stack of separate tools — an uptime checker, a server monitoring agent, and a status page service — with one dashboard, one lightweight agent, and one flat, predictable price. Teams use Xitoring to know about problems before their customers do: a website going down, a disk filling up, an SSL certificate expiring, a cron job silently failing, or a database running out of memory. When something breaks, the right person is alerted within one minute through the channel they actually answer. Who is Xitoring for? Xitoring is built for DevOps teams, system administrators, managed service providers (MSPs), hosting companies, SaaS businesses, and growing SMBs that self-manage Linux or Windows infrastructure. It delivers the feature depth teams expect from enterprise monitoring suites, at a price point and setup effort that fits teams of one to five hundred. MSPs can manage monitoring for multiple clients from a single account with team access and role-based permissions. Setup: one command, no configuration files Install the Xitogent agent with a single command — curl on Linux, MSI on Windows — and it immediately auto-discovers what is running on the server and starts monitoring it. More than 30 services are detected and configured automatically, including Nginx, Apache, IIS, PHP-FPM, MySQL, MariaDB, PostgreSQL, MongoDB, Redis, KeyDB, Docker (hosts and containers), RabbitMQ, Kafka, HAProxy, Varnish, Supervisor, and CouchDB. Supported platforms: Ubuntu, Debian, CentOS, RHEL, Rocky Linux, Amazon Linux, and Windows Server 2016 and later. Uptime monitoring Uptime checks run at 1-minute intervals from more than 15 global probing nodes. Every outage is verified from multiple locations before an alert fires, eliminating the false positives that plague single-location checkers — you get paged for real incidents, not routing hiccups. Check types: HTTP and HTTPS with keyword, status-code, and response validation; Ping (ICMP); DNS; API; Mail (SMTP, IMAP, POP3); FTP; TCP; UDP; Heartbeat; and Cron job monitoring. Heartbeat and cron checks catch the failures nothing else catches: backup scripts that stopped running, queue workers that died quietly, scheduled tasks that never fired. SSL certificate and domain expiry monitoring are included, with advance warnings before expiration — preventing the most avoidable outages of all. Server monitoring The Xitogent agent collects metrics at 1-minute resolution: CPU per core, load averages, memory, swap and page file, disk usage and I/O, IOPS, network traffic per adapter, and the state of processes and services. Historical data and trends support capacity planning and post-incident analysis. Docker monitoring covers both hosts and individual containers, with per-container CPU, memory, network, and state — so you can tell instantly whether a problem lives in a container or the underlying server. Alerting: 20+ notification channels Alerts route through more than 20 channels: Email, SMS, Phone Call, Mobile Push, WhatsApp, Telegram, Slack, Microsoft Teams, Discord, Google Chat, Mattermost, PagerDuty, Opsgenie, Splunk On-Call, Spike.sh, Ntfy, Gotify, Pushover, Pushbullet, Webhooks, and Zapier. Notification roles let you route different servers and checks to different people and teams, so the database alert reaches the DBA and the website alert reaches the web team. AIOps: monitoring you can talk to Xitoring includes a built-in AI assistant that is wired directly into your metrics, charts, and incidents. Ask plain-English questions — "which servers are running hot on memory this quarter?", "what likely caused last night's alert?", "compare disk growth across my web servers" — and get ranked, specific answers grounded in your actual data, not generic troubleshooting advice. Through the Xitoring MCP server (Model Context Protocol), AI assistants and agents such as Claude and Cursor connect directly to your monitoring: reading metrics, inspecting incidents, acknowledging alerts, and creating or modifying monitors. Your team's AI tooling gets the same access as the web panel. Xitoring is one of the few monitoring platforms at any price point that works natively with AI agents. Status pages and incident management Publish public or private status pages, hosted on your own domain and fully white-labeled with your branding, colors, and logo. Component status updates automatically from real check results — no one has to remember to post an update during an outage. Announce scheduled maintenance in advance, post incident updates from detection to resolution, and reduce support ticket volume when things go wrong. Incident management is built in, with root-cause context attached to every incident: which check failed, from which locations, what changed on the server, and which services were affected. SLA reporting documents your availability commitments. Apps, API, and integrations Native iOS and Android apps keep on-call engineers covered anywhere, with push notifications and full incident visibility. A complete REST API supports automation and custom integrations. A browser extension for Chrome and Edge puts monitoring status one click away. Pricing: flat, public, predictable Xitoring pricing is flat and published — no per-metric billing, no per-check surprises, no usage-based fees that spike after a busy month, and no "contact sales" wall. The free forever plan includes 2 servers and 8 uptime checks, with no credit card required. Paid plans start at $4.99 per month, and every paid plan comes with a 30-day free trial. Why teams switch to Xitoring Teams typically arrive at Xitoring from one of three places: outgrowing a basic uptime checker that can't see inside their servers; consolidating multiple single-purpose subscriptions into one platform; or leaving an enterprise observability suite whose usage-based bill became unpredictable. Xitoring's answer to all three is the same — full-stack server, uptime, and status page monitoring, deployed in minutes, with AI built in and a price you can predict.
