A tutorial focusing on Object Rules and discusses the best practices for monitoring in the SevOne Network Monitoring System.
Hello and welcome to another video showcasing the SevOne NMS. Today what we're going to focus on are object rules. There are a few best practices surrounding discovery of devices and in filtering objects within the SevOne NMS.
The first thing that we do want to suggest is that you start with a controlled discovery. Define and start with a single device what you truly want to monitor, review the objects that SevOne has imported during polling and determine from there what you want to truly monitor. We have object rules which is one type of automation so that you may filter out unwanted objects to relieve capacity and processing power from your appliance or virtual appliance. To navigate to object rules within my platform, I would select administration, monitoring configuration, and object rules.
While in object rules you will see a few default object rules that we have imported into your build of SevOne. Just to take a look at some of these defaults, we will take a look at a couple of the object rules. You'll see that we're filtering by device, by plugin or poller technology, and then we're defining the object that we care to restrict.
Let's go ahead, let's define a few rules, and disable a couple objects. I'm going to select create new rule and then this will showcase our rule creator. Where we will want to select device group first, now again, it is best practice to start with a particular device group, but you can apply these object rules to all devices, and all device groups. In this case and in this demonstration we'll focus on all Cisco devices, refer to the device group video for any questions on how to define a device group.
The next portion that we will want to define is the poller, and in this case we'll use SNMP as an example and then we will list all relevant objects under that poller. If there is a particular object you would like to filter within, you can define that. For the instance of this video, I will keep it board and focus on all objects. The next field that we will want to define is either object name or object description, both of these fields input and validate regular expressions, for this video I will show an example of perl expressions.
Again, coming back to our example, I will define that this expression will match what I've been putting in the field and I will start with a perl expression, essentially matching the beginning of the following strain. In this case perhaps we want to filter out and hide all quality of service objects, so in order to do that I'm just going to simply input QOS and match anything with that strain. What this expression will do is essentially take a look at all QOS objects and filter them out, disable them from our object manager and from our view so that it does not take capacity and it does not, more importantly, take licenses. We can input some notes so that other admins and we can refer back to it later and then we'll want to go ahead and save that. Once the rule has been successfully created you will see it listed at the bottom of your default presets. In order to delete a rule, you'll see the red X to the right hand side to simply remove even defaulted rules.
