Using scripts from Open Source project phpSysInfo it is quite easy to set up a simple system-health monitoring on any webserver that can run PHP files. This feature can be monitored using IPCheck Server Monitor.

The trick is that phpSysInfo shows red bars as soon as the available memory, CPU resources or disk space fall below a certain threshold. These red bars are shown using GIFs images with the word “redbar” in their filename. Using an HTTP Advanced sensor we are monitoring that the resulting HTML from the script does not include the word “redbar”. As long as this word is not included in the HTML the server works fine.

The U.S. Energy Policy Act of 2005 extended Daylight Saving Time (DST) in the U.S. by approximately four weeks. As a result, beginning in 2007, DST will start three weeks earlier on March 11, 2007, and end one week later on November 4, 2007, resulting in a new DST period that is four weeks longer than previously observed.

If your computer runs on an American or Canadian Timezone setting this situation affects your computer and software.

PortForward.com offers help for setting up port forwarding on many routers or firewalls. Most users are not aware of how to configure their router or firewall in order to use IPCheck’s Remote Probes in a remote network (or to offer access to PRTG’s or IPCheck’s webinterface from outside of the network).

The same applies to Peer-to-Peer file sharing (PtoP), Internet Games, Web serving, FTP serving, WebCams, IRC DDC, and Instant Messaging such as AIM, ICQ, Yahoo and MS Messenger.

Our Routers section offers detailed walkthroughs on how to setup port forwarding. These how to guides make it easy to setup your router or firewall for any application you may need.

An updated version of our MIB Importer Tool is available on the website. With this software you can easily import MIB files and convert them into OID libraries for PRTG Traffic Grapher and IPCheck Server Monitor.

In this latest version V1.1 we have improved the compatibility so that many “not-100%-RFC-conform” MIB files can now be loaded and converted (most in-the-wild MIB files are not conform to the RFCs…).

Using the SQL Server sensors you can natively monitor the most used SQL servers: MySQL, Microsoft SQL, and Oracle SQL.

Basically, the sensors monitor whether the database server process

• A: accepts connections and
• B: processes requests and
• C: returns an expected result when executing a custom SQL command.

We have added a new article to our knowledgebase with detailed instructions for the setup of SQL sensors in IPCheck.

If you receive the message “This program has been damaged, possibly by a bad sector of the hard drive or a virus. Please reinstall it.” when starting IPCheck Server Monitor, PRTG Traffic Grapher or Webserver Stress Tool then you either have a virus or trojan on your computer or a malfunctioning anti-spyware software.

Since the remote probe software version needs to match the IPCheck host software version it is always necessary to update the probe’s software each time the host’s software is updated.

In order to automate the process and to update the software in such a manner that the actual users working on the target machines barely notice the process, the following steps can be taken for a “silent” install.
