Re: [Nagios-users-br] RES: Nagios em rede GRANDE, BEM GRANDE.
O uso do protocolo TCP é mais confiável que UDP simplesmente porque o protocolo é orientado a conexão. Em palavras mais simples, ele faz a recuperação de pacotes de rede perdido no próprio protocolo, enquanto que o UDP depende da aplicação conferir e fazer a recuperação da informação. Mas as perdas existem tanto com o uso de um ou outro protocolo. E dependendo da escala de monitoração, usar TCP para contornar uma deficiência da rede pode trazer outros problemas. O SNMP pode oscilar não apenas por causa da rede, mas tbm pode falhar se o agent estiver com problemas. Existem técnicas adequadas para cada caso, mas se vc não tem uma conexão confiável por rede remota, melhor fazer a monitoração por um agent na rede local e fazer o relay dos resultados. Claro que estamos falando aqui de um evento de monitoração e não um alarme (notification, trap) no SNMP. Então para uma monitoração adequada, precisamos primeiro ver se a condição que gera os resultados indesejados é a rede e aplicar correções na rede ou mudar a topologia do agente Nagios para contornar a situação, por exemplo usando NSCA. Se a situação é mais devido à demora da aplicação SNMP do host monitorado, ajustar parâmetros de timeout pode ajudar. Um outro ponto a ser considerado é quantos threads podem ser rodados simultaneamente. Em se usando uma aplicação com uma resposta não muito imediata como o SNMP, faz sentido ter a máxima quantidade de threads simultâneos, uma vez que a interação com o host monitorado demora bem mais que uma interação com ping (por exemplo). Como vc usa o valor default, então não há limitações... mas vale a pena checar. Tem q ser zero. ;) sd, Edgar Em 5 de maio de 2010 12:19, Marcel mits...@gmail.com escreveu: Só alterar a conf do snmpd para escutar tanto udp quanto tcp, que é mais caro mas não há perda de pacotes! 2010/5/5 benedito.ra...@caixa.gov.br Alexandre, Grato pela resposta. Ocorre que, pela política imposta pela área de segurança da empresa, não é permitido instalação de qualquer arquivo no cliente monitorado. Ao que me parece, para que o NRPE funcione, tem que instalar e configurar o cliente, certo? Ou estou errado?

Benedito. Eu tinha esses problemas de timeout com snmp também. O snmp, por usar udp, é muito sensível a pequenas oscilações na rede. Passei a usar NRPE no lugar do snmp. Os problemas foram totalmente resolvidos e permitiu outros tipos de verificações nos sistemas e o uso do eventhandler para reiniciar processos.

Prezadas e prezados, Trabalho numa empresa estatal BEM GRANDE, em se tratando de quantidade de servidores e ativos de rede. Preciso de dicas para ajustar os parâmetros do Nagios para monitorar hosts e serviços em larga escala. Até hoje, usei o Nagios para monitorar 700 servidores e 2000 serviços na filial em que trabalho. Uso o Nagios Core 3.20, que tem funcionado legal para estes quantitativos. Máquina com 4 processadores e 4 Gb de memória. Todas as checagens são feitas via SNMP, através dos plugins do site manubulom, do nagiosexchange. Ocorre que surgiu a demanda para implementar o Nagios nas demais filiais, sendo que algumas têm muito mais hosts e serviços que a minha. A maior, tem 2000 hosts e 6000 serviços. Notem que será um servidor Nagios por filial. Na maior das filiais, incluí todos os 2000 hosts e 6000 serviços. A checagem de hosts está funcionando OK. Mas as de serviços, apresentam a mensagem Nagios check time-out em muitos casos. A máquina está com 16 processadores e 16 Gb de memória. Portanto, não acredito ser problema de insuficiência de hardware. Deixei os parâmetros default do nagios.cfg. Resumindo: - Preciso de dicas de como melhorar a performance do Nagios. - Existem parâmetros específicos no nagios.cfg, a serem alterados, para melhorar a performance em redes grandes como a minha? Tenho lido sobre hosts scalations e service scalations, mas não entendi muito. Será que resolveria meu problema? Grato, desde já, por qualquer ajuda.

[Nagios-users] Check for the IBM ds4000 series totalstorage cabinett - FIX
Hi,
after the latest firmware upgrade to a IBM DS 4700, the Check for the IBM
ds4000 series totalstorage cabinet stopped working.
I made a small fix to the perl plugin, just 2 lines. To have the plugin
working with the latest cli, make this substitutions:
Line 164
Change
if($line=~/Array status:\s*([^\s]*)/i) {
with
if(($line=~/Array status:\s*([^\s]*)/i) || ($line=~/Status:\s*([^\s]*)/i)) {
Line 167
Change
if(!defined($array_status) || !($array_status=~/online/i)) {
with
if(!defined($array_status) || !(($array_status=~/online/i) ||
($array_status=~/optimal/i))) {
Done, now it should work. The latest upgrade changes the output of cli
messages, that's why the script doesn't work anymore. The fix traps the
old and new status messages.
Hope it helps
Cheers,
Giorgio Zarrelli

Hi at all, I'm newbie on nagios and I'm writing here to ask you for suggestions abut how to structure my monitoring situation. I've to monitor linux servers for about 15/20 customers, from 1 to 5 server for each customer. We aren't on vpn with customers, so this servers are all behind NAT. That isn't a problem because we are the administrator of the firewall (other linux server) so we can manage any kind of DNAT and filter rule. I read on official documentation that suggest to use NCSA addon for distributed monitoring, but we choose to use NRPE addon for different motivations like: -customer force us to do that -the number of monitored servers for each customer will never grow up -the services to monitor for each server are the same (raid hw/sw, disk usage etc) -we need a completly centralized monitoring structure For last sentence I thought to use the arguments option on NRPE (yes, I read the SECURITY document). Besides, to solve the problem of NAT with NRPE I'll do DNAT on firewall and the port parameter on check_nrpe plugin (is there problems to do that? I did little tests but I prefear a confirm) To manage this structure I need to organized a well-formed config file structure on nagios server. I thinked to structure it like this obj--| |--templatelinuxserversgeneral.cfg | |--customer_1_directory|-templateserver.cfg | |-server1.cfg | |-server2.cfg | |-servern.cfg | |--customer_2_directory|-templateserver.cfg |-server1.cfg |-servern.cfg Where: -templatelinuxserversgeneral.cfg is a very basic template for server -customer_1_directory in wich there is 1 file for each customer's server -templateserver.cfg will use templatelinuxserversgeneral and will add more specific common variabiles for that customer's server like the public IPAddress that will be the same for each customer's server. -servern.cfg in wich there will be some very specific server variables like nrpe port (read up).

[Nagios-users] High latency when 15% hosts offline
Hi I'm running Nagios Core 3.2.1 Currently we have a network switch down, meaning all hosts beneath that switch are unreachable, 42 in number (from a total of 336) . In Nagios I have the switch set up as the parent. The switch I have set to be in scheduled downtime until we get a replacement, to prevent notifications being sent out. I am finding that the service check latency is enormous and the scheduling queue is slipping behind in time. For example, it is now 11:04am and the next check at the top of the scheduling queue should have run at 9:52am. Here are the service metrics from the Perf. Info page; Check Execution Time: 0.00 sec30.19 sec 2.170 sec Check Latency: 0.00 sec13612.54 sec7025.395 sec Percent State Change: 0.00% 17.37% 0.50% Are there any ways I can reduce this latency, other than disabling active checks on all the unreachable hosts? Or any 'parallel' check tweaks I may have mis-configured?

I read on official documentation that suggest to use NCSA addon for distributed monitoring, but we choose to use NRPE addon for different motivations like: -customer force us to do that -the number of monitored servers for each customer will never grow up -the services to monitor for each server are the same (raid hw/sw, disk usage etc) -we need a completly centralized monitoring structure For last sentence I thought to use the arguments option on NRPE (yes, I read the SECURITY document). Besides, to solve the problem of NAT with NRPE I'll do DNAT on firewall and the port parameter on check_nrpe plugin (is there problems to do that? I did little tests but I prefear a confirm) To manage this structure I need to organized a well-formed config file structure on nagios server. I thinked to structure it like this obj--| |--templatelinuxserversgeneral.cfg | |--customer_1_directory|-templateserver.cfg | |-server1.cfg | |-server2.cfg | |-servern.cfg | |--customer_2_directory|-templateserver.cfg |-server1.cfg |-servern.cfg Where: -templatelinuxserversgeneral.cfg is a very basic template for server -customer_1_directory in wich there is 1 file for each customer's server -templateserver.cfg will use templatelinuxserversgeneral and will add more specific common variabiles for that customer's server like the public IPAddress that will be the same for each customer's server. -servern.cfg in wich there will be some very specific server variables like nrpe port (read up). What do you think? How can I organize that service-server combination?

Re: [Nagios-users] Different contacts for services on same host
Sebastian Gosenheimer wrote: Hi everybody, i'm just having some problems with my contacts and contactgroups. Let's say, i have a contactgroup xy and a contact ab. I set up a host with the contactgroup xy and some services on this host with the contactgroup xy. But now i have a special service on this host, where i only want notifications send to the contact ab. Nagios is also sending the notification e-mails correctly to the contact ab, but it's also sending the notification e-mails to the contactgroup xy. Can someone tell what i'm missing? Thank you for your help! Kind regards, --sg Is the service using any templates ? Does the template have a contactgroup directive in it ? you need to override any template or wide definitions that cover the service and put in the service specific definitions the directive : contacts ab this will tell the service to just send to the specific contact .

[Nagios-users] nagios.cmd does not seem to work properly
Hello, We'd like to use nagios.cmd pipe to send some signals. According to the examples in documentation, we can do a simple thing like that : /bin/printf [%lu] ACKNOWLEDGE_HOST_PROBLEM;host1;1;1;1;Some One;Some Acknowledgement Comment\n $now $commandfile The problem is, it seems it's not taken in account - no log in nagios.log, no message is printed in shell, and more over nagios doesn't seem to do anything. I tested with an error inside the command, and it seems to be parsed: [1273156151] Warning: Unrecognized external command - SCHEDULE_HOST_SVC_CHECKs;fqdn;1273156151 but nothing else happens. Is there a way to be sure that nagios do what we ask? The main thing is: - we're using NSCA plugin so that we have about 80 servers with their own nagios, sending results and status to a single host - we tried to run this command only on remote hosts - maybe we have to use it on the nsca server ? Any help is welcome. Thank you in advance !

Although the nagios debug file fills up and grows quite fast so you need to make sure to have sufficient space to have the input you want . from what I know - external commands are logged in the nagios log - again check the option in the nagios.cfg Assaf -- Never,Ever Cut A Deal With a Dragon I am doing a Charity Bike ride On the 27 of June for the Capital to Coast Charity.

You do, of course, have to run this on the Nagios server, since that's where the pipe is. The message in your log seems to indicate you typo'd the SCHEDULE_HOST_SVC_CHECK command. If you're using NSCA, your pipe works: it submits commands to Nagios the same way. -- ___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
