Nagios Support Forum

Hi,
I am new to the Nagios and planning to use Nagios XI in my company . I did some research and but still have few questions about some features of Nagios XI product and also I would appreciate if you provide reference - Docs/URL’s along with that.

1. How can we setup alerting in Nagios when a polled metric crossed the threshold limit. For example, if CPU/bandwidth utilization crossed 90% on a switch.
2. Metrics/Data roll up configuration – Raw polled data retention policies and Data aggregation policies.
3. The polling interval configuration - Is it possible to setup group of elements to poll at 1min , some other group to 5min, etc.
4. The timeout/retries setup in Nagios.
5. Is there any Auto-grouping feature available for discovered components/elements based on their types/categories.
6. Does it support Cisco IPSLA.
7. Detection and rediscovery of appliance upgrades/reboots.
8. Alert severitization that can be passed northbound to an event management tool.
9. New technology/vendor device support – How to onboard new technologies in Nagios.

Please help me here to provide the information.
Thanks

Generally speaking, it's a good idea to split separate questions into separate threads. What may seem like an easy question could turn into debugging and possibly bug fixes.

1. I think the generic documentation @Derick Wasswa sent is probably sufficient for this
2. Can you clarify what you mean? We do have reporting.
3. Yes, but I would not suggest 1 minute unless you have a really powerful server
4. It will depend on the plugin. You should definitely create a new thread for this.
5. If I understand what you mean, then no. There is auto-discovery
6. A lot of plugins that work in XI are written by third parties. For example, Cisco has this https://communities.cisco.com/docs/DOC-52673 . The best thing to do if you want to know if there is a plugin for what you want to do is to fire up your favorite search engine. Sure, we may know of something, but we are only here during US working hours, so the search engine may be faster for you.
7. Possibly. Certainly you can detect if things go down and then come back up. It would depend on the OS how easy it is to determine whether it was an admin-generated reboot.
8. You'll want to look at service escalations.
9. I suspect the general links will suffice, but if you have specific questions, those are probably best address in a separate thread.

Thanks for the reply. I made some research and not able to find the respective materials - doc's/URL's for the few points. for example, for point 1 I am not able to get the information where to setup threshold alerting, etc. Much appreciate if you please help here to get the details.

To some degree, this will depend on the plugin. However, you will want to look at Page 4 of https://assets.nagios.com/downloads/nag ... ios-XI.pdf

The other pages will provide some context, but the heart of your question is on page 4.
