Nagios Plugin for Cacti (NPC) Released

[slander]

I created it myelf and placed the recompiled inserter.c there - and added back the link. Still, no love.



You have an inserter.o, (the compiled one, not the source .c file) in /usr/local/nagios/module, right?

[knobdy]

For me, that line is /usr/local/nagios/var/rw

the nagios.cmd file is a pipe. I think it will create it itself.

I don't have one - that I can find.

One other thing - did you remember to change the database info in the inserter source code, since that is compiled in?

Yeah, the second time. Well, and maybe this will make a difference: I recompiled the inserter file. Re-ran the nagios install, etc.. Then when I realized I had forgotten to change the db info I just recompiled inserter and copied it over the last one. Would that make a difference?

[knobdy]

You have an inserter.o, (the compiled one, not the source .c file) in /usr/local/nagios/module, right?

Yeah, sorry, I do. But there wasn't a module folder until I created it...

Code: Select all

# ls -altr /usr/local/nagios/

-rwxr-xr-x  1 root   root   61701 Jun 23 14:03 inserter.o

Perhaps chmod inserter.o? module rather than modules (its correct in nagios.cfg)?

modules is correct.
your permisssions are the same as mine, should be ok.

How about, when you start nagios there should be an entry in /usr/local/nagios/var/nagios.log, something like:

[1151089984] Nagios 2.4 starting... (PID=29359)
[1151089984] LOG VERSION: 2.0
[1151089984] initializing nagios-db mysql inserter...
[1151089984] nagios-db: inserter locked into db
[1151089984] Event broker module '/usr/local/nagios/modules/inserter.o' initialized successfully.

[knobdy]

bingo! Its still the db authentication... will do it again, more carefully this time.

Still not sure of myself when it comes to linux file management commands...

So, anymore development on this plugin? I just registerd on the nagios-uk forum and they've mentioned it a couple of times.

And since you guys are answering: I've got several sites running on this Apache. For Nagios I finally created a seperate vhosts file (required, apparently, in order to use another scriptalias?). Unfortunately it seems I missed something because I *appear* to be missing some of the graphics. For instance, the Nagios "Tactical Overview" page has to Network Health images on the right hand side - I only get what looks like placeholders (which appear to grow with health). The green buttons in the menu bar on the left are there, but they're called at http://url/images/greendot.gif where as the health buttons are supposd to be at http://url/nagios/images/thermok.png.

I am not the author - just a user of it! I would like to see some more development here too. It is a great start, and is almost there!

[knobdy]

Any ideas on the image issue though?

Hi,

Does anyone know why this website http://www.divagater.com/npc/ isn't running ?
Does there exist a mirror ?

Hi all. I have been away from these forums for quite a while. I apologize that the site hosting NPC went down. Some one did post NPC to this forum with the following link:

http://forums.cacti.net/download.php?id=5127

That is still the latest release available. NPC has not been abandoned. My production environemnt relies heavily on Cacti and NPC. The little company I worked for was bought buy a very big comapny a few months ago. All my spare time has been involved with integrating our technologies and since NPC worked "good enough" I have not touched it. Thats the problem with 1 man projects

I am currently "albeit slowly" working on a big rewrite of NPC to use the ndo2db module written by Ethan Galstad. His module will support all Nagios events and will likely stay up to date with new Nagios features. I am also trying to integrate privilege seperation so hosts or services can be viewed only by people with the appropriate permissions.

I can't promise any time frame on this. If there are any PHP/MySQL folks that are interested in helping speed this along I would be glad to collaborate.

I may be interested in helping out a little. Mainly one of the features that I would like to implement is the passing of check result data between the two. Currently I am writing a nagios plugin that checks the rrd files from cacti for certain thresholds and reports to Nagios. I don't think an all-encompassing plugin would be feasible right now, but a couple designed to submit the standard Cacti graphs could work. I am currently working with perl since the RRD::query and RRD::poller modules work nice, but it could be ported it to PHP in theory. We could use something like that running off of the cmd.php and reporting to nagios via passive service check (nagios.cmd). It is just a matter of changing the output a little.

[benzopila]

or, please, can anyone attach his own compiled insterter.o?
maybe some match to my os.

Thanks.

[JJX]

hi all, where can i get this file?
The url in the first post isnt working


thx

[benzopila]

Hello!
I have some progress in that question.
I've updated nagios from 2.0b3 to 2.5 and now there is so problem:

There is this messages when compiling insterter.o:

gcc -g -O2 -Wall -o inserter.o inserter.c -shared -L/usr/local/lib/mysql -I../include -I/usr/local/include/ -lmysqlclient -fPIC

inserter.c:842: warning: long unsigned int format, time_t arg (arg 6)
inserter.c:872: warning: long unsigned int format, time_t arg (arg 3)

What about this warnings? Are they critical?
but file is compiled finally.

hi all, where can i get this file?

thx

What file do you mean?

[benzopila]

Hello!
I've found mistake:

[1156750357] Lockfile '/var/spool/nagios/nagios.lock' is held by PID 41815. Bailing out...

This file /var/spool/nagios/nagios.lock must be deleted before restarting nagios.

Now NPC working so I have a few new questions

Not possible but you can link graphs to NPC so they're embedded.
While under console click Devices pick a device that's also in Nagios you'll see a new option called Nagios Host Mapping.. select the right Nagios Host and save it. When in NPC viewing the host there will be a Graph View option under the Host name that will take you to the hosts for that graph.

This feature is working properly and I can choose hosts from nagios at dropping menu(Nagios Host Mapping - Select the Nagios host that maps to this host).
And after that as result I can view associated graphs for host
(while under host at the top of the page - "View graphs").

While under the services for a host at the bottom of the page you'll see Graph Mapping.. select the Cacti graph that goes with that service and when you view that service the graph will be at the bottom. Also while viewing a list of services there will be an extra graph icon that when click will display the graph under the service.. its pretty cool..

But I can't to associate graph at Graph mapping.
There are no associated graphs for services
(while under the services for a host at the bottom "Graph mapping").
I mean there is nothing but "none" at dropping menu in "Associated graph:".
Can anybody help?

Hey, just out of curiosity, how hard would it be to create a web frontend for editing the nagios config files (for adding hosts and such)?

Now if they can only get the hostgroups/Servicegroups and config working. Oh and the acknowledge in the list of commands would be ncie.

What about these features?

I can't promise any time frame on this. If there are any PHP/MySQL folks that are interested in helping speed this along I would be glad to collaborate.
~Billy

Billy, I'm a nooby at this question, but I need to learn PHP and MySQL and want to help in development. I'll send this message to you by email.
If you need help, just reply.

Thanks. Sorry for my poor English.
