Boa noite,
Pessoal gostaria de receber alguma dica para deixar o nagios checando
instântaneo pois quando um host
cai, demora cerca de 10minutos para atualizar que o host está down e isso
vem me causando problemas

Re: [Nagios-users] NRPE vs. check_by_ssh
Kevin Keane wrote: Christopher McAtackney wrote: 2009/3/25 Kevin Keane subscript...@kkeane.com: I think you are comparing apples and oranges here, because in most situations that I can think of, the decision is dictated by the network topology. If you are exclusively on a trusted private network, check_by_ssh really doesn't offer any benefits. Conversely, if your topology involves the Internet or some other untrusted network (WiFi), then you wouldn't want NRPE in the first place. The only exception to the above that I can think of is when it comes to deciding between using check_by_ssh over an untrusted network, vs. NRPE through some other kind of tunnel or VPN. But in that case, you'd incur encryption overhead either way, and the comparison is very different from the question you asked. All that said: I don't have any first-hand experience, but I suspect that the impact of establishing 2200 ssh connections in a five-minute span (assuming that you are using a five-minute check interval) is pretty substantial. The main impact actually lies in establishing and tearing down the connections, key negotiations etc.; the encryption during the data phase probably has only limited impact because most checks only transmit a few bytes back and forth. SSH does much better with longer-duration connections when the keys are already exchanged. This is even more true if you have a router-based VPN, because in that case the overhead is offloaded to a different machine. So if you have the option of sending the checks as NRPE through one or a few long-term VPNs: you are probably going to be better off. Of course, in the big picture, your mileage may vary. Firstly, thanks for the detailed explanation of the issues involved in this choice Kevin, it's been very helpful. I'm curious though, could you elaborate on why NRPE is unsuitable if communication with my remote hosts is going to go via the Internet? Is it not sufficient that NRPE uses SSL? This may be more of a network security question than a Nagios one, but I've no real experience in either area unfortunately, so I appreciate any info you can give here. No, you are right. I wasn't aware that NRPE could use SSL. In that case, NRPE would be pretty much the same in terms of performance as SSL. That said, I am generally concerned from a security standpoint about any kind of active checks going over the Internet. This is because if you are monitoring, in your example, 200 hosts, you have to poke holes into 200 firewalls (or into one firewall, and then set up SSL or SSH keys on 200 hosts). That's 200 potential security holes all over the place with little or no control, and on machines that may not necessarily be hardened for access from the outside world. Worse - active checks, by nature, cause a program to be launched and executed on the monitored client, and usually with very high permissions. You said that you check 2000 services, so that's 2000 plugins (give or take a few). What if a hacker found a way to compromise one of your 2000 plugins? You'd have a privilege escalation issue along with remote-launch capability. On 200 clients. Very high permissions are normally not needed. I prefer using NRPE because of two reasons: 1. It provides a rather simple way of specifying exactly which commands can be run, and with which arguments (don't enable argument parsing in nrpe if the receiving end isn't duly protected by firewalls etc) 2. If someone breaks into the Nagios server, he or she does not get the public keys required for running commands on the remote servers. Because of these concerns, I am using passive checks almost exclusively over the Internet (except for publicly available services such as HTTP or SMTP, of course); I wrote an agent that resides on the client as a wrapper around the excellent NSClient++ and performs the actual checks. It then forwards the checks to the Nagios server via NSCA over HTTPS. A second benefit is that this agent collects about 40 or so check results, and then sends all of them at once through a single SSL connection. That reduces the overhead of establishing a secure connection by a factor of 40. BTW, the agent is available as Open Source. Go to http://www.tntmonitoring.com . Sounds like a rather neat solution, although I suppose it has to be configured in both ends before it's actually useful (although all other agents require some configuration anyways, so perhaps it's not such a big deal). I'm not too fond of relinquishing the re-check logic of Nagios though, but I guess you can't get everything. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace.
Re: [Nagios-users] Nagios and MySQL
Mark Weaver wrote: Hi List, I was wondering if anyone has connected their standard Nagios installation up to a MySQL backend? I'm looking at this from a purely disaster recovery aspect. It's easy enough to backup the configuration, but the data is another matter. Why you would want to move data from flat files to a database for disaster recovery purposes is beyond me. Care to explain? My current Nagios installation is version 3 installed on a CentOS 4.7 server. The installation was done via Yum from the rpmforge repo. Much cleaner install than compiling the tarballs and much easier to manage. Yes, I could archive all the installation paths, but because they were installed via the RPM method things are spread out all over the file system. It would be real nice if I had all the data contained within a MySQL backend. That way if I had to restore should my Nag server die or suffer some horrible fate it could be a matter of reinstalling the packages, restoring the /etc/nagios directory where all the configs live, restore the database and I'm of again. This should work reasonably well: tar czf nagios-backup-$(date +%Y-%m-%d.%T).tar.gz $(rpm -ql nagios) I've looked at a few suggested Nagios front ends including Centreon and they turned out to be bad experiences. Mostly due to the fact that being a Nagios noobie I didn't know what the hell the front was doing. The worst of it though was the way those front ends kept over-writing my configuration files in favor of it's own. Made a real mess of things and after the third reinstallation of Nagios on my sandbox I decided they weren't worth the effort or the misery. (Centreon and NagiosQL) Groundworks is out of the question because as soon as it was installed and running it disabled my current instance of MySQL in favor of it's own. Not such a big deal as at the time it was on my sandbox machine, but had that been a production machine where I've got web applications running I'd have been seriously pissed! Funny that... Groundworks didn't mention anything about that rather rude behavior. No, I'd much rather be able to connect a standard Nagios install to a MySQL backend and use everything else as is. What particular data is it you want to put in the database? We have plenty of scripts, eventbrokers and programs written specifically to gather Nagios data and put it in a database. If you use our webconfiguration tool, it will overwrite your configuration files when you click save, but that's sort of expected behaviour, I guess. Still, I think you're going about this the wrong way if you only want it for backup reasons. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- ___ 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
Re: [Nagios-users] Dependent service checks don't fail when depended-on service check fails
Jarrod Moore wrote: Hello everyone, I have a couple of related questions regarding service dependencies in Nagios and their limitations. I have two service checks (let's call them A and B) and service A depends on service B to function correctly. I want to set Nagios up so that if service B crashes then both services A and B are put into the critical state in Nagios. I've tried using service dependencies in Nagios to represent this behaviour but have yet to be successful. I can only get it to suppress notifications of service A if both services go down. This is expected behaviour. If A is truly dependant on B, then A will turn into a non-ok state of its own volition rather than as a result of any dependency magic. Dependencies are designed as a means of suppressing notifications. Otherwise, you would *always* get a notification for B first, and a minute or so later from A (actually, without the dependency you could get from A first). Is there a way to do what I'm trying to do here? I'd have thought it would be logical that if a service depends on another service and the service depended on dies then all services depending on it would fail their checks as well, but there;s probably some scenario where it doesn't work so well. I've had a look through the mailing list archives and found someone had asked a similar question to the nagios-devel list about 2.5 years ago and didn't end up getting an answer, so I thought I might ask whether solutions to this type of problem had been developed since then. They haven't. You're using dependencies the wrong way, really. If A is truly dependent on B and doesn't go into a non-ok state after B has crashed, then your check isn't doing what it's supposed to do, or you've misunderstood the relationship somehow. If you were to explain what the two services actually are, it would be easier to point you to a solution that works. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- ___ 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

[Nagios-users] Uniquely Identifiable Events in Nagios.log?
Hi all, I was wondering if it is possible to configure Nagios to produce uniquely identifiable entries in the nagios/var/nagios.log file? The reason I ask, is that I would like to parse this log file for service check results and perform further processing based on the values discovered there. The trouble is, that as far as I can see, Nagios uses a time-stamp which is only accurate to the second, and so my log files have lines which all have the same time-stamp. Is there a way to increase the accuracy of this time-stamp perhaps? Or any other suitable solution to the general problem of identifying log entries?

[Nagios-users] NDO update delay
Hi everybody. I´ve installed NDOUtils (nodutils-1.4b7) whith Nagios (nagios-3.0.6) and it´s working. However I´ve noticed that it´s taking more than 30 minutes to update the MySQL tables. I´ve detected the problem making a query on the field last_check on nagios_hoststatus table. Can anyone help me? There is a parameter to make the update process faster?

I've zeroed out the values for contacts and contactgroups, which should
effectivly hide this service unless cgi.cfg tells otherwise for that user.
But, any user is able to view this service, why?
Ive tried to add myself to the contacts line and remove the contact_groups,
so it would look like this:
contacts tore
#contact_groups
But this still doesnt work, are regular operators are still able to view the
service, why? Operators are members of a operators group, which is a
contactgroup for all hosts.
Any tips would be gratefull :)

That's 200 potential security holes all over the place with little or no control, and on machines that may not necessarily be hardened for access from the outside world. Worse - active checks, by nature, cause a program to be launched and executed on the monitored client, and usually with very high permissions. You said that you check 2000 services, so that's 2000 plugins (give or take a few). What if a hacker found a way to compromise one of your 2000 plugins? You'd have a privilege escalation issue along with remote-launch capability. On 200 clients. Very high permissions are normally not needed. Depends on the plugin, but I'm not sure that this is generally true. For instance, something as simple as log file analysis either requires root permission on Linux; log files aren't readable by anybody else, or it requires that you relax file permissions or security somewhere else. On Windows, I'm running my monitoring agent (by default) as the Local System account (most Windows services do that anyway). That has basically full access to everything, but nothing on the network. Of course check_ping, check_tcp etc. don't usually need such high permissions. I prefer using NRPE because of two reasons: 1. It provides a rather simple way of specifying exactly which commands can be run, and with which arguments (don't enable argument parsing in nrpe if the receiving end isn't duly protected by firewalls etc) 2. If someone breaks into the Nagios server, he or she does not get the public keys required for running commands on the remote servers. Can you explain that second statement? I'm not sure I follow what you are trying to say here. Why would getting public keys be a bad thing? They are, by definition, freely available anyway. Because of these concerns, I am using passive checks almost exclusively over the Internet (except for publicly available services such as HTTP or SMTP, of course); I wrote an agent that resides on the client as a wrapper around the excellent NSClient++ and performs the actual checks. It then forwards the checks to the Nagios server via NSCA over HTTPS. A second benefit is that this agent collects about 40 or so check results, and then sends all of them at once through a single SSL connection. That reduces the overhead

refers to a macro containing a path to the location of your script.

I have two service checks (let's call them A and B) and service A depends on service B to function correctly. I want to set Nagios up so that if service B crashes then both services A and B are put into the critical state in Nagios. I've tried using service dependencies in Nagios to represent this behaviour but have yet to be successful. I can only get it to suppress notifications of service A if both services go down. This is expected behaviour. If A is truly dependant on B, then A will turn into a non-ok state of its own volition rather than as a result of any dependency magic. Dependencies are designed as a means of suppressing notifications. Otherwise, you would *always* get a notification for B first, and a minute or so later from A (actually, without the dependency you could get from A first). Is there a way to do what I'm trying to do here? I'd have thought it would be logical that if a service depends on another service and the service depended on dies then all services depending on it would fail their checks as well, but there;s probably some scenario where it doesn't work so well. I've had a look through the mailing list archives and found someone had asked a similar question to the nagios-devel list about 2.5 years ago and didn't end up getting an answer, so I thought I might ask whether solutions to this type of problem had been developed since then. They haven't. You're using dependencies the wrong way, really. If A is truly dependent on B and doesn't go into a non-ok state after B has crashed, then your check isn't doing what it's supposed to do, or you've misunderstood the relationship somehow. If you were to explain what the two services actually are, it would be easier to point you to a solution that works. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. Well basically I have a map (similar to Google Maps) embedded in a website, which hits a URL to retrieve maps. So I have one check using check_http to check that the website itself is up and another check on that URL to make sure that the map service is available. Now if the map service goes down, the website is still up but the maps won't appear, which means the website's functionality is significantly affected. However, it is still up and viewable so doing a check on the website URL still passes. Now of course I could just write a script or something to check both URLs and set that as the check command. There is a problem for me with this approach, however, because I have some other instances where a web service depends on other web services. When I want to use these services in websites, I'd then have to write a check for each script, each containing every service in the chain that is needed to display the website correctly. This way of doing things just seems a bit repetitive to me, especially when I have a check for these web services already. -- ___ 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
