How to set the variable for LMS monitoring

Unanswered Question
Jan 28th, 2009

I have a LMS 2.6 which is monitoring the cisco devices. Everytime when the server switch is utilized high due to backup services there will be alert triggered. How can i set the "high utilization" to make LMS alert me when the utilization is high let say for 20 minutes before triggering the alert.

Thanks

I have this problem too.

This is not possible. You are able to adjust the threshold and the polling interface (40% and 4 minutes are the default), but you cannot do delayed events or X of Y type correlation.

I have a question. I have a cisco ASA5505 Firewall on my network. I just added a new server to the network and want to move sonic wall security on to this new server.

I want to edit the configuration on the Cisco ASA 5505 firewall such that the IP Address of the old server is replaced by the IP address of the new server. The new server would be hosting the sonic email securitry if I can have the firewall point to this new server.

If i have one interface that i want to disable for high utilization feature how can i go about doing it in LMS.

Thanks

You can do this in one of two ways. You can either unmanage the interface under DFM > Device Management > Device Details, or you can modify one of the custom interface groups under DFM > Configuration > Other Configuration > Grouping, disable the high utilization threshold for that group under DFM > Configuration > Polling and Thresholds > Managing Thresholds, then set the priority of that group to be higher than the built-in group for that interface type under DFM > Configuration > Polling and Thresholds > Setting Priorities.

Finally, apply the changes under DFM > Configuration > Polling and Thresholds > Apply Changes.

Look like i can only disable the high utilization for all the interfaces or unmanage the interface. But i want LMS to monitor the interface but except high utilization. Is there any way to do it?

Joe Clarke Mon, 02/02/2009 - 09:32

No. The second set of instructions I gave you, the ones for modifying a custom interface group to match only this interface, will allow you to disable high utilization events while keeping other aspects of the interface managed.

Cause i have one group that contain all the routers and switches. How can i create another group in DFM and include those switches that i want to disable high utilization?

Thanks

Joe Clarke Mon, 02/02/2009 - 17:57

You don't create a group. Instead, you modify one of the built-in custom interface groups. You'll see these listed under DFM > Configuration > Other Configurations > Group Administration. Choose one of those groups that is not already being used, and define a ruleset which matches the devices and interfaces for which you want to disable the high utilization event.

Then, under DFM > Configuration > Polling and Thresholds > Managing Thresholds, modify the threshold settings for that group, and set the Utilization Threshold to 0. Then, adjust the interface group priorities under DFM > Configuration > Polling and Thresholds > Setting Priorities so that this customized group is listed first. Finally, apply your changes.

Under the rule expression and Rule text. What do i need to add in to tell LMS that it is this switch and this particular interface?

Thanks

Joe Clarke Mon, 02/02/2009 - 20:53

That's up to your specific device naming scheme and interface configuration. If it were one interface on one device, you would want a rule which matches on that specific device name, and the specific interface you want.

The interface name as it is known to DFM can be found in the Detailed Device View under DFM > Device Management Device Details.

There are Customizable Group 1

Customizable Group 2, Customizable Group 3, Customizable Group A , Customizable Group B, Customizable Group C. Can use either one is it?

For utilization parameters the field need a valid number any method to disable just that?

leo_zidane Tue, 02/03/2009 - 20:24

There are four user defined groups Customize Access Port Groups, Customize Groups, Customize Interface Groups and Customizable Trunk Port Group.

Trunk port Groups means those ports that have trunking enabled is it. LMS will auto detect it right?

What is the different between Interface Groups and Access Port Groups?

Lastly there is another Groups itself?

Joe Clarke Tue, 02/03/2009 - 20:29

You need to use one of the interface groups if the object in question is a routed interface (i.e. one with an IP address). Access ports are switch ports which do not connect to another DFM-managed device. Trunk ports are switch ports which do connect to another DFM-managed device.

So if my server is in this VLAN, i want to do a customize group to disable the utilization feature i will use the Access ports group. In the rule expression i will match the element name of the interface. Am i right?

Thanks

Joe Clarke Tue, 02/03/2009 - 20:39

What type of device is this port/interface object on? what is the config for this interface/port?

leo_zidane Tue, 02/03/2009 - 20:48

It is just a normal switch access port which belong to a server vlan. It is a cisco catalyst switch.

Thanks

Joe Clarke Tue, 02/03/2009 - 21:58

If the port doesn't have an IP address, and is configured as a switchport, then you will need to modify one of the access port groups. That said, access ports are not managed by default, so you shouldn't be getting high utilization events for these ports unless you explicitly managed them.

If you did, and you would like to manage these ports for everything but high utilization, you can still do that following all of the guidelines I laid out previously. You can also have your ruleset match multiple ports on this one device by using the OR operator.

leo_zidane Tue, 02/03/2009 - 22:35

I tried to set 0 on utilization to disable it but LMS alert me immediately that utilization is high.

Another question is LMS will based on priority of group is it. So if i define my customize group element name on the top it will overwrite the system group right?

Joe Clarke Tue, 02/03/2009 - 22:52

Sorry, I confused this threshold with another. For High Utilization, set the threshold to 100.

Right. The priorities work like access-lists: the first match wins. So, if your custom group has a higher priority than a system-defined group, then anything matched by your ruleset will have the thresholds applied based on that group, and not the system-defined group.

Remember, any changes you make in priorities or thresholds require you to apply your changes.
