[Nagios-users-br] Ndoutils e problemas de performance
Olá a todos. Estou utilizando em ambiente de laboratório o Nagios 3.0.6 com ndoutils 1.4b7 e MySQL 5.0 em uma máquina Linux CentOS 5.2 (2.6.18) x64 com 2GB ram e processador Intel Xeon 2.50GHz. Optei em utilizar o ndoutils para manter informacoes históricas de checks no banco de dados (tables nagios_servicechecks e nagios_hostcheks), assim como utilizar o NagVis para representacao gráfica das minhas redes. Os testes funcionais foram bons, porém cheguei ao ponto do projeto em que tive que fazer um benchmark com um número de 7.000 services, simulando o que vou encontrar em ambiente de producao. Carregando o broker ndomod porém sem executar o daemon ndo2db consigo uma performance boa de service checks com quase 95% dos services sendo processados na janela de 5 min e com uma latência de check baixa. Importante ressaltar que todos os services são ativos (não passivos) com check_interval de 5 minutos. Ao executar o daemon ndo2db, onde o mesmo inicializa o socket unix e comeca as operacoes em banco de dados, percebo uma perda considerável de performance do service check com apenas 9% dos services sendo processados na janela de 5 min, latência alta de checks e o contador de iowait da CPU entre 90% e 100%. Services que deveriam ser processados pelo daemon do Nagios em 5 min são processados com delay de até 1 hora, o que inviabiliza a solucao como ferramenta de monitoracao. Como o MySQL está na mesma máquina, fiz o tunning nele (buffer, threads, etc), apliquei índices adicionais as tabelas e testei passando as tabelas do database nagios para o esquema blackhole. Desta forma o banco aceita conexões e operacoes (select, insert, delete, ...) porém não grava os dados em disco. O iowait continuou alto e a performance ruim. Não desconfio mais do banco de dados. Percebi que o daemon do ndo2db utiliza apenas 1 conexão com o banco de dados para fazer diversas operacoes por segundo, sendo que cada operacao aguarda o final da execucao anterior. O que particularmente acho ruim. Pergunta: alguém utiliza as facilidades do ndoutils com banco de dados em grande instalacoes do Nagios ( 1500 hosts 7000 services) e que não tenha estes problemas de performance para me dar uma luz ? As configuracoes do Nagios estão abaixo. Segui algumas recomendacoes de tunning para o Nagios do documento http://nagios.sourceforge.net/docs/3_0/tuning.html Obrigado.

Re: [Nagios-users] Nagios Service Dependencies
2009/5/7 Dei Bertine deibert...@yahoo.com:
Basic question guys:
Which file do you normally place your service dependencies in?
It stated here: http://nagios.sourceforge.net/docs/2_0/dependencies.html
to place in objects cfg file which I thought placing it in my nagios.cfg
But when I did, it complained about this error after running -v:
Error in configuration file 'nagios.cfg' - Line 2859 (NULL value)
Here's a sample of my definition:
define servicedependency{
host_name ciscoasa-router
service_description PING
dependent_host_name ciscosw-router
dependent_service_description PING
execution_failure_criteria o
notification_failure_criteria w,u
}
Please advise.
Thank you!
DB
I would put service dependencies in a file called something like
'servicedependencies.cfg'.
in nagios.cfg, you need a pointer to this new file, for example:
cfg_file=/usr/local/nagios/etc/objects/servicedependencies.cfg
The nagios.cfg file should only contain the main configuration file
options which you'll find documented in
http://nagios.sourceforge.net/docs/3_0/configmain.html
But ... I'm not convinced you should need service dependencies for
'ping' from one host to another. Nagios handles this sort of thing
automatically if you configure the host parent relationships. See:
http://nagios.sourceforge.net/docs/3_0/networkreachability.html

Re: [Nagios-users] PNP swap template HOWTO
Hi Ayotunde, You need to create template file with name of service command name.php (i.e. check_mem.php whatever command name you use) , if this file doesn't exist in template dir, PNP will use default template. default template for check_swap (in template.dist) shows swap free rather than swap utilized, you need to modify template to show swap utilization.

I noticed that this inverts the SWAP utilization graph i.e., the red and yellow lines (warning/critical) are very close to the bottom of the graph while the utilization shows as almost 100% (close to the top) instead of very low is it actually is. I have copied the check_swap.php from the templates.dist directory into the templates directory, deleted all the existing swap.xml and swap.rrd files, and restarted the npcd daemon. I have also tried renaming check_swap.php to swap.php. I noticed also that all my graphs use the Default Template and the XML files for all of them have TEMPLATEcheck_nrpe/TEMPLATE.

Re: [Nagios-users] check_snmp - warning numbers
Hola de nuevo...
I'll answer you in English so that anybody in the list can understand and
participate in this subject.
I think that if you don't know exactly which parameter to monitor you should
browse the whole OID list that you receive when you do a snmpwalk on your
switch, and identify the ones that fit your needs, with the help of the website
I said yesterday, or any other OIDs reference.
My case: The only thing I want to detect is if there is any damaged port in any
of my switches. So what I did was to snmpwalk on a switch which I positively
knew that had its port #2 damaged, and discover which OID was significantly
different for this port. And the one I found is:
iso.3.6.1.2.1.10.7.2.1.7
(maybe you can find it as its equivalent: SNMPv2-SMI::mib-2.10.7.2.1.7)
defined as: a count of frames for which the first transmission attempt on a
particular interface is delayed because the medium is busy.
The thing is that it's the only OID I found that gave a very high value for
port #2 (about 65,000 or so) and 0 for the rest of ports that work properly.
The command I defined for this was like this:
define command {
command_name check_port
command_line $USER1$/check_snmp -H $HOSTADDRESS$ -C password -O
iso.3.6.1.2.1.10.7.2.1.7.$ARG1$ -w 1 -c 10 -u retries
}
For sure there must be somebody else in the list who can give to you a more
detailed or a more formally correct answer...
Hasta la proxima,
Alejandro

Hola Alejandro,
Ahora otra cosa:
De que manera crees que pueda chequear los puertos de mi switch con nagios para
tener una idea más clara de lo que está sucediendo?
Porque esos paquetes entrantes con errores no se si son por causa de la PC o de
los puerto del switch...
Muchas Gracias...
Cristian
Hola Matías... :-) and hola everyone...
There exists a magical website where to identify every OID you can check with
SNMP, the link is:
http://support.ipmonitor.com/mibs_byoidtree.aspx
For your particular issue, if you type RFC1213-MIB at the Search for: form,
click the result given (RFC1213-MIB), and then View:
Oid-tree, you'll be able to locate ifInErrors(14) at the tree shown, and
clicking it you'll find its Description, which reads literally:
The number of inbound packets that contained errors preventing them from being
deliverable to a higher-layer protocol.
That's the answer to your question!!
Now some other questions appear...
Wouldn't it be nicer to know what exactly are you monitoring before you monitor
it, so you could properly interpret the results?
Is that parameter (number of inbound packets that contained errors and blah
blah blah...) significant enough to determine if a port is working properly or
not?
Hope this helps...
Best regards,
Alejandro

Re: [Nagios-users] Nagios Service Dependencies
Hi Jim,
Thanks for clarifying to me et al, I will definitely give this a shot.
I'm sure this will benefit the others who thought of building this config in
their Nagios, especially for a newbie like I... :-)

Subject: Re: [Nagios-users] Nagios Service Dependencies
2009/5/7 Dei Bertine deibert...@yahoo.com:
Basic question guys:
Which file do you normally place your service dependencies in?
It stated here: http://nagios.sourceforge.net/docs/2_0/dependencies.html
to place in objects cfg file which I thought placing it in my nagios.cfg
But when I did, it complained about this error after running -v:
Error in configuration file 'nagios.cfg' - Line 2859 (NULL value)
Here's a sample of my definition:
define servicedependency{
host_name ciscoasa-router
service_description PING
dependent_host_name ciscosw-router
dependent_service_description PING
execution_failure_criteria o
notification_failure_criteria w,u
}
Please advise.
Thank you!
DB
I would put service dependencies in a file called something like
'servicedependencies.cfg'.
in nagios.cfg, you need a pointer to this new file, for example:
cfg_file=/usr/local/nagios/etc/objects/servicedependencies.cfg
The nagios.cfg file should only contain the main configuration file
options which you'll find documented in
http://nagios.sourceforge.net/docs/3_0/configmain.html
But ... I'm not convinced you should need service dependencies for
'ping' from one host to another. Nagios handles this sort of thing
automatically if you configure the host parent relationships. See:
http://nagios.sourceforge.net/docs/3_0/networkreachability.html

Jim

Re: [Nagios-users] Im confused about scheduled downtime and notifications
Hi All, We've just migrated from Nagios 1 to 3.0.6. I have a host that was in scheduled downtime and turned off. I turned it back on, while still in scheduled downtime, and got a HOST UP alert for it. Is this expected behavior? Could I have a misconfiguration somewhere, where should I look? Has anyone else seen this? I've occasionally seen notifications for hosts in scheduled downtime, but only in the few seconds after restarting the Nagios daemon. I don't think it's expected behaviour, no. In this case the daemon had been running for 3 days. I've not bothered to find a fix for it, as it happens only rarely and so long as I don't restart the daemon at three in the morning, it won't bother anyone. This was on a host that had just been retired, I turned it back on to get a file off of it and that's when the alert was sent, it had been offline for a while. The interesting thing was that Nagios only sent a UP alert when I shut it down again (a few minutes later) the alerts for down were not sent (as would be expected). It does not appear to be a major problem (no one else responded), I'm not going to worry about it too much.

[Nagios-users] Escalations Info
Hi all, I'm trying to understand the escalation process in Nagios but think I'm missing a trick somewhere, this is what I want to do. If I have a service that is down I would like 3 email sent out and then after the 3 mails I would like this to escalate this to send out SMS sent and then stop. So in my escalations I have the following but unsure if it’s the correct format. First escalation: 3 because as I understand it this will occur after 3 mails have been sent. Last Escalation: 3 because I want 3 SMS sent after my 3 mails.

Asunto: RE: [Nagios-users] check_snmp - warning numbers
Hola de nuevo...
I'll answer you in English so that anybody in the list can understand
and participate in this subject.
I think that if you don't know exactly which parameter to monitor you
should browse the whole OID list that you receive when you do a snmpwalk
on your switch, and identify the ones that fit your needs, with the help
of the website I said yesterday, or any other OIDs reference.
My case: The only thing I want to detect is if there is any damaged port
in any of my switches. So what I did was to snmpwalk on a switch which I
positively knew that had its port #2 damaged, and discover which OID was
significantly different for this port. And the one I found is:
iso.3.6.1.2.1.10.7.2.1.7
(maybe you can find it as its equivalent: SNMPv2-SMI::mib-2.10.7.2.1.7)
defined as: a count of frames for which the first transmission attempt
on a particular interface is delayed because the medium is busy.
The thing is that it's the only OID I found that gave a very high value
for port #2 (about 65,000 or so) and 0 for the rest of ports that work
properly.
The command I defined for this was like this:
define command {
command_name check_port
command_line $USER1$/check_snmp -H $HOSTADDRESS$ -C password -O
iso.3.6.1.2.1.10.7.2.1.7.$ARG1$ -w 1 -c 10 -u retries
}
For sure there must be somebody else in the list who can give to you a
more detailed or a more formally correct answer...
Hasta la proxima,
Alejandro

Hola Alejandro,
Ahora otra cosa:
De que manera crees que pueda chequear los puertos de mi switch con
nagios para tener una idea más clara de lo que está sucediendo?
Porque esos paquetes entrantes con errores no se si son por causa de la
PC o de los puerto del switch...
Muchas Gracias...
Cristian
Hola Matías... :-) and hola everyone...
There exists a magical website where to identify every OID you can check
with SNMP, the link is:
http://support.ipmonitor.com/mibs_byoidtree.aspx
For your particular issue, if you type RFC1213-MIB at the Search
for: form, click the result given (RFC1213-MIB), and then View:
Oid-tree, you'll be able to locate ifInErrors(14) at the tree shown,
and clicking it you'll find its Description, which reads literally:
The number of inbound packets that contained errors preventing them
from being deliverable to a higher-layer protocol.
That's the answer to your question!!
Now some other questions appear...
Wouldn't it be nicer to know what exactly are you monitoring before you
monitor it, so you could properly interpret the results?
Is that parameter (number of inbound packets that contained errors and
blah blah blah...) significant enough to determine if a port is working
properly or not?
Hope this helps...
Best regards,
Alejandro

Hi, I am using the check_snmp nagios`s plugin. And when we check the
ports status of a 3com Baseline 2250 Plus, we recibe many ports results:
SNMP OK - 0
SNMP WARNING - *1*
SNMP WARNING - *84*
SNMP WARNING - *2*
SNMP WARNING - *2*
SNMP WARNING - *4*
The question is, what´s the meaning of the warning numbers?
Other information:
--

[Nagios-users] Multiple alerts from one script (Windows Eventlog monitoring)
Hello everyone. Started testing Nagios since last February, and am very much please with the functionality. I currently have a pilot Nagios implementation, monitoring about 100 Windows 2003 servers. I have one WinXP client, installed with a NSClient++ agent. All checks are executed remotely from the WinXP workstation, which acts as a proxy. My servers are agentless. Now I have created a vbs script to collect entries from the Windows eventlog, alerting on filtered errors, warning, eventsource, eventide, etc. For each defined filter I create one Service in Nagios (eg. I have one service checking for Antivirus events, another service checking for Printserver events, one service checking for DNS events, etc.) Each run of the script could report on multiple events. At the moment the script creates one single alert, showing multiple events. However, I would like to A. have one alert generated for each unique event (in order to use the notification mechanism). If possible I would like to implement an event-database, where I would be able to handle each unique alert. Something similar to MOM, where a count of each unique event is displayed, and as long as the event is not yet closed no new notifications are being sent out. B. In the end, I would like to implement some module, that will create a ticket in our Ultimo helpdesk system, for each new alert generated. Is this feasible with a combination of NSCA and Nagios Eventdb ? I have not yet been able to get the Eventdb running properly yet, so at the moment I am unable to assess the value of this tool. Also with NSCA I have just started playing. However, after some time I started getting NTVDM errors, which would only resolve with a reboot from my proxy.Th built-in NSCA functionality in the NSClient++ will only allow me (or so it seems) to run one instance of every defined script at a regular interval. Has anyone implemented something similar yet, and how did you get everything up and running ?
