 Posted: Tue Jul 17, 2007 12:20 pm Post subject: Feature request for threshold alerting |
 |
|
Is it possible to implement dependencies for the alerting feature in threshold? If the router is dead I dont want to receive notifications for all other network devices that are also now not available because the one device that was the link to those devices is unavailable.
Is there an easy way to do this or would this be a feature request for the plugin? |

I've been waiting for this request to pop up    
As we're using Tivoli Monitoring in our company for Alerting (yes, shame on us), we have implemented the Rule Engine of Tivoli Enterprise Console. This does exactly what you're asking for. But it is _really_ not that easy to create/maintain such rules. Personally, I fear that implementing a generic rule engine will be too complex.

Couldn't it work in hand with the Manage Plugin?
The Manage Plugin currently knows where the devices are located on the network via Sites. If you were to do some basic rules where you associate a site with a link, if the link goes down, then it alerts on the down link, but does not alert on all devices behind that link.
I've been wanting this feature as well. |

This feature is one reason we are still with Nagios for our monitoring. It allows you to set parent/child relationships, and you can down the parent, and have it cascade down to the child. Actually, that is another feature i would love to see in Cacti, a Parent/Child relationship. I have 7 sites, and i would love to be able to group them in that fashion. Have the PIX that is the first device in the site be the parent, and then the other equipment be the children. Would be nice for the children to have children too.
I hope to see some of this in the future releases of the product, or plugins.

| This is something I'd like to see as well. The comments above make sense, as we are also multi-site, and have devices with dependancies. |

Is this something you have already done or you are saying it might be able to be done? |

It's Holiday season in France. So, I am guessing that he is doing just that. I sent him a PM and did see your note.

I'm saying it could be done. If you're using Manage, then you already have your equipment broken down by site. It would need to be integrated so that it only alerts on the link being down, and not everything behind the link. |

This is event correllation. Someone needs to do some forensics with other products and then we also need an event management engine with event correlation as an option.
I think there is a lot of work to do there. I am working on an event management engine for Grid Computing as we speak. I am sure it will have a general application once it is done. Maybe branded differently.

| Could we perform a notification queue rate limit? If the default gateway does go down as described above, and you are monitoring or polling a goodly number of devices, your cell phone is UNUSABLE for the time those messages come flooding in. Needs to be a rate limit....? |

I would love to help out with it, but I don't know php enough to even get started. All my background is in VbScript. |
