Corner Bowl Internet Server Monitor
Uptime, network, server and application monitoring software tool for IT professionals
a sub-component of Server Manager
What is Internet Server Monitor?
Corner Bowl Internet Server Monitor is an extensive enterprise-class software monitoring and management tool for IT professionals that minimizes downtime by proactively notifying IT when degraded server and application performance is detected. Includes uptime monitoring, website monitoring, email server monitoring, SSL certificate monitoring, database monitoring, Windows server monitoring, SNMP monitoring and much more. Supports Windows, Linux and Docker containers.
Corner Bowl not only checks the availability of server applications but in most cases includes functionality to test the application performance. For example, our website monitor template includes options to check both the response code and contents.Online Documentation
System administrators can setup monitoring hierarchy to shut down, start, or throttle up backup system monitoring when a primary server fails. For example, when a ping monitor fails on a primary server the system can shut down the dependent memory and CPU monitors while also throttling up ping, memory and CPU monitors on your backup server.Online Documentation
Schedule and Failure Rate
- Includes extensive scheduling options.
- Apply maintenance windows and exclusions rules (e.g. Disable database monitors every Sunday between 2 AM and 4 AM).
- Supports failure rates (e.g. Trigger ping alerts after 3 failures occur in 20 seconds).
- Save monitor results to the history database.
- View, search and page historical results.
- Display historical charts.
- Automatically removes old results no longer required.

How does Corner Bowl do it?
Depending on the monitor and your requirements, Server Manager utilizes different technologies to scan managed hosts and application servers:
- When managing Windows Servers, you can optionally use our Windows client-side Agent to bypass Windows Security and instead use our proprietary FIPS compliant TLS 1.2 application layer protocols to scan and manage machines faster and more reliably than native technologies such as remote WMI. When utilized, our software does not require administrator log on as access credentials nor are logon events generated on domain controllers minimizing our software's footprint on your network.
- Otherwise, Windows servers are managed using a combination of remote WMI and Windows Shares (SMB).
- Linux servers are managed using a combination of SSH Shell, SFTP/SSH, FTP/S and SMB (Windows Shares) and Syslog.
- Application servers such as websites, email servers and DNS servers are monitored using their appropriate application layer protocols.
- Databases are monitored using each vendor's RDBMS specific .Net library.
- SNMP Traps are monitored using our own SNMPv3 Trap server with FIPS compliant AES-256 encryption support.
