There are SNMP devices that sometimes change the OID for a specific counter. This is common for systems running Windows 2003. If this happens PRTG can not continue to monitor this counter and it is easiest to add a new sensor.

If the historic data needs to be bound to the new sensor in order to retain the monitoring structure please refer to our knoweldge base article Binding historic datasets to new sensors and recalculating historic data for an individual sensor.

Last night we have celebrated our new office space with a housewarming party for our team and the local network that keeps the company going. Thanks to everyone who joined us and enjoyed the party!

We have had multiple queries regarding strange, respectively wrong readouts when monitoring certain ASA equipment. As we found out today, the problem is a bug in the 7.2 OS causing the SNMP iftable to forward erroneous return values to monitoring software, such as PRTG. Instead of graphing PER vlan values, this bug results in graphing the total number of untagged vlan packets for each vlan.

Version 5.4.1.855 of IPCheck Server Monitor includes some changes and enhancements for SQL and System sensors and a bugfix for WMI sensors.

See the history for details and download this latest version.

WMI (”Windows Management Instrumentation”) is Windows built-in monitoring and management technology (introduced with Windows 2000). It’s a great way to monitor Windows systems in your network.

IPCheck Server Monitor already works with WMI. As accessing WMI counters over a network is not exactly trivial, our new Paessler WMI Tester is a tool that can be used to test the accessibility of WMI counters in a quick and easy manner.

The IT publication WindowsIT Pro has included PRTG in its latest collection of dynamite freeware for your USB toolkit. See the press clipping.
