Please Don't give up on us end users we live for new plugins.

I am apparently horrible at estimating how long things will take but I am really getting close now. The alpha version will be for the brave and hardy to shake down the UI. For the last week I have been working on implementing all of the most useful Nagios commands. This part is pretty tedious because there are a lot of forms and the forms all implement a little business logic to build the command correctly. I will probably do the first release after I am done building all these command forms (Maybe this weekend if my wife lets me stay inside

Below are a couple points of what to expect with the 1st release.

* The UI will have everything needed for monitoring. In some cases like the status map and the reporting I simply wrapped the nagios UI in an iFrame minus the left hand menu. You can see an example of this in the status map screen shot in my first post.

* Actual Cacti integration will be weak at first. The UI is of course fully integrated into Cacti. There is a one way Nagios to Cacti host sync, and a php script that makes getting Nagios perfdata very easy. Easy does not mean automatic but I think it will be very useful for people wanting to trend nagios perfdata.

* There are numerous other data points where deeper integration into Cacti makes sense. Those will come some time after the 1st alpha release.

* Requirements: For those that want to get ready the requirments are pretty rigid at the moment. PHP 5.2, Cacti 0.8.7b, Nagios 3.0, ndoutils-1.4b7.

Cheers,
Billy

Woot!! I was looking at upgrading to the latest versions since i have some time on my hands.. would be nice to get a new NPC working in the new version.

Are you supporting nagios v3?

Nagios 3.x is all I am supporting. Chances are good that it would work on 2.x but I haven't tried and don't really have the time too right now. When I first started writing NPC Nagios 3 was in beta and to me it made sense to write against 3.

Hey -

I have this installed, and it's working great - the interface is a huge improvement! I'm wondering if there are plans to actually have Nagios query the Cacti RRD files for host status, rather than having Nagios/Cacti poll the host twice for each OID that is monitored? It seems like these two features could be relatively easily combined, especially if used in conjunction with the Cacti plugin that lets you poll hosts in whatever interval you want (1min, 2min, 5min, etc).

Thanks again for a great improvement!

Greg

Hello,

I must write you to say what a great piece of software NPC is!! It has been extremely helpful to our company. We are monitoring over 100 objects with NPC integration.

Great work!

I finally got NPC 2.0.0b (Build 164) working. The most challenging part was locating a php 5.1 x64 rpm for my Redhat 4 and rebuilding for 32 bit, then having to build json on top of that. After all is setup, now I can say: what a great piece of work npc is.

I'm wondering if there will be an import feature for service checks, as there are for hosts. I am already using nagiosgraph to drraw them, but it requires a bit of grunt work to link all of the data sources up and set the graph settings. I haven't used the part of nagiosgraph to link the graph urls in with nagios yet, because I'm thinking it would be nice to have it all exist in cacti.

Anyhow, this is a great integration plugin. Good work and I look forward to doing betas on the new versions.

One comment: Nagios 3.x does support multi-line output. It would be great to have this for NPC as well. If this could also be displayed in the 'tactical overview' equivalent (as opposed to just in the 'service detail' equivalent), it would take full advantage of displaying multi-line plugin output. Please add this to the wishlist!

Thanks!

I have host groups configured and they can be seen in nagios, but i cannot import anything via the N2C importer. It tells me I have no host groups. Any clues to where I should start looking?
