Best Log Aggregation software for the cost. Nice little gem of a tool to use for companies that don't want to spend more on logging software than the actual applications and systems that need to be monitored. Can perform AD security auditing and alerting. Windows Update alerting. Syslog alerting.

Windows SSL Certificate Store Monitoring

Production Windows servers often have many different types of SSL Certificates installed. For example, your production server might have multiple web server SSL Certificates, an email server SSL Certificate, a SQL Server SSL Certificate and an SFTP SSL Certificate. Use Internet Server Monitor to quickly monitor them all through the Windows Certificate Store Monitor.

EV Code Signing Certificate Monitoring

If your organization develops software it is likely your development team is protecting their binaries with EV Code Signing Certificates. Internet Server Monitor includes support to validate EV code signing certificates and send notifications before they expire.

How does Corner Bowl SSL Certificate Monitor do it?

SSL Certificate Monitoring is available as a sub-component of both Corner Bowl Event Log Manager 2021 and Corner Bowl Server Manage 2018. When you purchase either an Internet Server Monitor license or a Server Manager license simply register your license in either our latest monitoring software, Event Log Manager or our tried and true Server Manager software.

Once registered, Corner Bowl Software enables you schedule SSL Certificate monitoring and EV Code Signed executable file monitoring. SSL Certificates and referenced Intermediate Certificates are scanned for validity and expiration. If an SSL Certificate expires within 30 days or there is an SSL Certificate Chain Error, Corner Bowl Software sends daily email notifications to the responsible IT administrators until the SSL Certificate is updated.

Windows Management Instrumentation (client and server)

Many functions within Corner Bowl Software utilize Microsoft's Windows Management Instrumentation (WMI) API (e.g. Event Log management, CPU and memory monitoring). This software includes options to optimize WMI packet size and performance.


Internet Server Monitor (ISM) is a sub-component of both our software packages, Corner Bowl Server Manager and Corner Bowl Event Log Manager. To access ISM functionality either install Corner Bowl Server Manager or Corner Bowl Event Log Manager then apply either a purchased Server Manager or ISM license.

Corner Bowl Software is sold in node packs. Each unique IP address or hostname that is monitored, scanned or managed by the software is a node.

Corner Bowl Software can be installed on a single host or up to as many hosts as nodes purchased.

For example, a 100 node license would enable an IT professional to install the software on 3 servers with one installation monitoring 50 servers and the other two installations monitoring 25 workstations each for a total of 100 nodes.

After you purchase a license, you have the option through this website or your reseller to upgrade your existing license with more nodes.

Once you have purchased a license, a license key will be emailed to you. If you purchase through a reseller, a claim link will be emailed to you enabling you to retrieve your key from this website. Once you have your key you will register online through the software's management console. If you are installing this software on an Air-Gapped network, you will generate license key files through this website where you will also find detailed instructions on how to apply your Air-Gapped key files.
