About

CoreBit Network

Features
Read full description

CoreBit is the mobile companion to the CoreBit network monitoring server. When something breaks in your network, you know about it — wherever you are. Built for network administrators and on-call engineers, the app gives you a fast, clear view of what is happening right now: which devices are up, which are down, what has gone wrong and who is handling it. INSTANT ALERTS • Push notifications for device outages, metric alarms and incidents • Severity levels, so critical problems break through Focus while routine notices stay quiet • Tap a notification to go straight to the incident or device • Alerts follow your on-call schedule and mute settings from CoreBit INCIDENTS • See active and acknowledged incidents at a glance • Acknowledge, change status, add a resolution note and assign incidents to yourself or a colleague • A clear summary of what happened, when it started and which devices are affected • A chart of the affected metric around the time of the incident • See who else is following an incident, so you know you are not alone DEVICES • Search and filter all your devices by status • Live vitals: CPU, memory and disk, with history charts for the last hours • Custom metrics with clear status values, active metric alarms and threshold markers • Recent activity and the full device log ON DUTY • See who is on duty right now • Mute alarms for yourself, a colleague or everyone for a set time (admins) • Mute a single device while you work on it AI ASSISTANT • Ask questions about your network in plain language, such as "Which devices are offline?" or "What happened to the core switch last night?" • Answers are based on your CoreBit server's live data (requires the AI assistant to be set up in CoreBit) MULTIPLE SERVERS • Connect to several CoreBit servers and switch between them in one tap • Notifications open on the right server automatically SECURE BY DESIGN • Pair by scanning a QR code from CoreBit — no passwords stored on the phone • Every phone must be approved by an administrator before it can see anything • All traffic is encrypted, and each phone gets its own access key that can be revoked at any time • The app connects directly to your own CoreBit server — no separate cloud account needed • Optional dedicated app port, so only the app's limited access needs to be reachable from outside REQUIREMENTS The app requires a CoreBit server (version with mobile app support). Your administrator creates an invite in CoreBit under Settings → Security → Mobile Apps. To learn more about CoreBit, visit corebit.network.
