Nagios Plugin for Cacti (NPC) 2.0.4

[aaronnicoli]

Okay glad I am not the only one, it seems that ponwude has the same issue I am having...

[aaronnicoli]

As an update well, I am afraid I am still having the same issue, please can someone help out with this.

Only thing I get in error log is:
[Thu Nov 05 11:18:51 2009] [error] [client XXX] PHP Notice: Undefined index: action in /var/www/html/cacti/plugins/npc/top_graph_header.php on line 95, referer: http://XXX.au/cacti/plugins/npc/npc.php

But by the looks of it, shouldn't be causing the issue I am having, this seems due just to not having anything to graph...

Please help me out with this guys

Hi All,

My Nagios and NPC is working now. I went back and rechecked all setup lines from the guide. i apparently had a typo somewhere.

I have another question though. do i have to manually enter host information for all the routers i want to monitor in the switch.cfg file??? sounds tideous.

please can someone post an example configuration for a router + services. The example in the guide isn't so explanatory.

thanks

Good to hear you got things working ponwude,

However, I still have the same fate, after checking and rechecking everything again as per the guide, still nothing....

Have have seemingly done everything, set permissions to 777 on things I had doubt about and still no go...

I wish someone could help me out though...

I am having trouble graphing the information from NPC.

The data input method is working:

From the Cacti log:

11/06/2009 12:30:02 PM - CMDPHP: Poller[0] Host[0] DS[644] CMD: php /var/www/cacti/plugins/npc/perfdata.php --type=service --id=264 2> /dev/null, output: designGallery(secs):1.329221

From the command line:
[root@xxx rra]# php /var/www/cacti/plugins/npc/perfdata.php --type=service --id=264 2> /dev/null

designGallery(secs):2.135832


However if I use rrdtool to fetch the rrd:

[root@xxx rra]# rrdtool fetch choosethis_644.rrd AVERAGE
choosethis

1257454200: nan
1257454500: nan
1257454800: nan
1257455100: nan

1257457500: nan
1257457800: nan
1257458100: nan
1257458400: nan

It returns all NaNs.

Debugging the rrd shows it is ok.

I have followed this guide: http://www.cacti.net/downloads/docs/html/how_to.html over and over


I would really appreciate any help with this problem.

Please guys it has been four days and have got nowhere, can someone please give some things to try out....

Been over the quick install notes about 50 times now....

[aaronnicoli]

Still cannot get things going its has been 2 weeks and have not got anywhere please help me out here...

[stevetuk31]

Can someone let me know how to increase the height of the portlets, as i am unable to do it through the portlet configuration.

Thanks in advance.

[aaronnicoli]

Finally fixed the issue myself.

The SQL doesn't create the needed default columns....

I ran the following to fix the database and actually get somewhere...


ALTER TABLE `npc_hostchecks` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_hoststatus` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_servicechecks` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_servicestatus` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_statehistory` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_eventhandlers` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_systemcommands` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;
ALTER TABLE `npc_notifications` ADD COLUMN `long_output` varchar(8192) NOT NULL default '' AFTER `output`;

Hello,

This is a great plugin and it's working ok in my test environment but before going into production I was wondering if it's possible to grab information for the Data Input Method from "Status Information" instead of only "Performance Data". I have several plugins that do not post any information in the Performance Data field, only in the Status Information.

I've been looking through the threads and I haven't read anything about it.

Thanks for your help!

Hello!

I've installed this plugin, but have some quesitons:
I've 3 servers, every server has it own service running:
1.st server for cacti
2.nd server for nagios
3.th server with database and NDO2DB

I've a Nagios server with ND02DB in production that log all the content to an esternal server on MySQL.

1. It's possible to set up cacti NPC to work with an external nagios?
2. It's possible to set up cacti NPC to work with a different prefix? I still log on a different host, having diffferent database and different prefix.
3. It's possible do set up cactiNPC to have external command enabled for a remote host? As allready written, the nagios server is not the same server as cacti.

Thank's a lot!

Hi,

Check the rrd file ds name. Must be the same as the output ds name.

rrdtool info choosethis_644.rrd | grep ds
output should report something like
ds[designGallery(secs)]

I dont know this brackets are allowed or not...

Check the same ds info on a working datasource and its data input method profile.

for example load average output:
load1:0.650 load5:0.180 load15:0.060

and the rra ds names are:
rrdtool info rra/localhost_load15_17.rrd | grep ds

ds[load1].type = "GAUGE"
ds[load1].minimal_heartbeat = 600
ds[load1].min = 0.0000000000e+00
ds[load1].max = 5.0000000000e+02
ds[load1].last_ds = "0.650"
ds[load1].value = 1.9500000000e+00
ds[load1].unknown_sec = 0
ds[load5].type = "GAUGE"
ds[load5].minimal_heartbeat = 600
ds[load5].min = 0.0000000000e+00
ds[load5].max = 5.0000000000e+02
ds[load5].last_ds = "U"
ds[load5].value = NaN
ds[load5].unknown_sec = 3
ds[load15].type = "GAUGE"
ds[load15].minimal_heartbeat = 600
ds[load15].min = 0.0000000000e+00
ds[load15].max = 5.0000000000e+02
ds[load15].last_ds = "U"
ds[load15].value = NaN
ds[load15].unknown_sec = 3


My problem is why does not get the load5, load15 value?? I can only see load1 in rra file and on the graph.

rrdtool fetch rra/localhost_load15_17.rrd AVERAGE -r 900 -s -1H
load1 load5 load15

1259317500: 7.9533333333e-02 nan nan
1259317800: 5.3333333333e-04 nan nan

Hi,

I have installed NPC 2.0.4 on Debian Lenny according to the quick start guide on http://trac2.assembla.com/npc/.

I have everything working so far. The npc_* tables in the database are populated partly (there is the necessary entries in npc_hosts, e.g., but nothing in npc_hoststatus). There is no data sink errors in cacti log.

I do not see any host status or service status in the npc tab, nagios status is everything green.
In Console => devices I only have localhost, but with defined nagios host mapping it should show up in the npc pane, should it not? It does not.

I have carefully screened every post on this problem (and tried every proposed solution), I think, but I do not find what I did wrong.

Any hint or help is appreciated.

What version of NDOUtils are you using?
