Most SNMP monitoring can be facilitated by comparing the value of a specific retrieved SNMP object to an expected string or threshold, but monitoring for some conditions can only really be accomplished by comparing the current value to a previous value. Three examples of this are: 1) Serial Interface Flapping: If a serial connection is [...]

While the SCOM Reporting implementation provides a great set of reports out of the box, there are a number of custom reports which I have found useful to develop. The report described here is one to report on aggregated hourly performance counters collected on SNMP Network Devices. First up, the queries:

I had previously written a post about using customization of SCOM’s resolution states to generate an additional notification, on-demand, in order to send the event to a helpdesk software system. Another resolution state customization that I have found useful facilitates the opposite effect, preventing notifications. Unlike those generated by monitors, alerts generated by rules in [...]

On a number of occasions in the past few weeks, I’ve found myself wishing there was an easy way to search a machine’s event log for events that matched a string in the description. I’ve primarily wanted such a utility while troubleshooting SCOM management packs, where I wanted to be able to filter for events [...]

The native Web Application monitoring capabilities of SCOM are impressive to say the least, and provide excellent functionality for in-depth monitoring of complex web application transactions. However, the administrative effort required to configure web application monitoring makes the implementation less than ideal for wide-scale basic web site monitoring. In most cases, required web monitoring would [...]

It seems like a favorite request of auditors is one for lists of all members of a set of local or domain groups that are associated with a resource that is being audited, and these requests typically stipulate that all members of nested groups must be listed as well (i.e. full recursion). I used to [...]

HP provides great SCOM management packs for monitoring of Proliant servers, but only Windows agents are supported by these management packs. If you’re running ESX on Proliant servers, it takes a little bit more effort to implement monitoring of hardware status. Fortunately, HP also offers their Management Agents for ESX. Thus, all that is needed [...]

It’s easy to argue the case for keeping accurate documentation of SCOM management pack monitors and customizations, both for the abstract purpose of maintaining good documentation, as well as the more practical purpose of being able to answer the “can you list what is being monitored?” question. However, it can be tedious to keep on [...]

While Sun, like most server vendors, offers a comprehensive suite of hardware monitoring agents and management tools, it can be frustrating to monitor Sun hardware using the Sun Management Agent and a third-party SNMP tool, such as System Center Operations Manager. The Sun Management Agent’s SNMP implementation builds on the Entity-MIB (http://docs.sun.com/app/docs/doc/817-3155/6mip4hnov?l=en&a=view) with the SUN [...]
