[Nagios-users] qpage - OT
Cheers All, I know a number of people use qpage for sending alerts via modem as we do. I'm hoping someone can help me with a qpage problem we're having, there does not seem to be a qpage mailing list and as of yet the developer has not responded to my email. We are getting *random* alert pages that fail to send with the following error. I say random because I have not figured out any patterns or commonality between them (other than the obvious they are all from Nagios, etc.). Roughly once a day a page will fail to send but others before and after it will send fine, they all use the same send script. We've always had some problems but they recently got worse after we replaced a failed PCI modem with a USB modem from US Robotics. Is anyone else using USB modems, if so what brand/model? Has anyone seen problems like this? Is the a better forum or mailing list I could look to for help?

Re: [Nagios-users] trying to fix problem with excessive latency
Hi All, This is just a me too post to hopefully help others down the road! I have inherited maintenance of a medium-sized Nagios installation. We currently have 649 hosts and 5415 services. Our setup works nicely, with one exception: Nagios falls behind on host/service checks. Our usual latency once Nagios has been running for a while is about 190-200 seconds. Our Nagios host is reasonably powerful and isn't struggling; it seems that Nagios itself is limited somehow. We are similar in size 530 hosts, 3300 service checks with a service check latency of around 300 seconds and 350 for hosts. There are no obvious performance bottlenecks on our sever the closest thing to it for us was the CPU's ave of around 30% utilization across 4 procs with 4 GB of RAM. Our current configuration did not have any latency issues running Nagios 3.1.2, our latency issues started a couple of weeks ago with an upgrade to 3.2.2. >It looks like use_large_installation_tweaks did the trick. I could have sworn I tried that before; likely I set it to 0 instead of 1 or something foolish like that. We've avoided this in an effort to keep our configuration as plain as possible and because I remember reading that this was not expected to be effective unless you had something like 1000+ hosts and many more service checks. Apparently that is not correct, at least under 3.2.2. >Anyway, I wanted to test the individual components of large_installation_tweaks to see what helped. >* child_processes_fork_twice=0: latency drops from 149 to 18 This change took our latency from ~300s to .228 for services and ~350 seconds to .458 for hosts >* free_child_process_memory=0: latency drops from 149 to 0.6 I made this change with the 'child_processes_fork_twice=0' change still in place and saw no measurable drop in latencies. >* disabling summary macros in environment variables doesn't seem to be > individually configurable, but I expect that's disabled already by > enable_environment_macros=0.

Re: [Nagios-users] Nagios did not send notification to some contacts --again
Hi All,
We had an event several weeks ago, it has happened again, I'm posted
after the first time and reposting to the same thread because they are
related. Sorry if this makes the it confusing. Marc thanks for the
reply to the first event, see below for my responses.
In the second event a host went down due to a power outage but only a
portion of the contacts were sent notifications (which is the same
problem as the first event). This is the second time, that I know of,
that Nagios has failed to send to some of the contacts. The problem has
now occurred on two different hosts. I can't explain why it's happening
which does not instill confidence in our customers. Any help or
suggestions in fixing this are greatly appreciated.
This next part is from/for the first event
first event --
>> There was a routing issue on our WAN that caused this event, the SMTP
server we use is across the WAN. Could the routing issue have prevented
some of the SMTP notifications from being sent, wouldn't they just queue
up and go once the problem was resolved?
>They would be queued by the SMTP server running on your nagios machine.
Redelivery attempts would occur based on the configuration there.
Okay, makes sense.
>> I have seen messages that did not arrive at the recipients phone but
I've never seen Nagios not generate notifications for contacts that are
configured for that host or service. Has anyone else seen this, any
suggestions on a cause or how to troubleshoot?
>- Check nagios.log for a HOST NOTIFICATION event for that group. Make
sure there were no errors logged.
nagios.log only shows notifications sent to some of the contacts, these
notifications were received.
>- Check your local SMTP server logs to see if the messages were
received there and no errors were reported.
Not necessary, nagios did not send the notifications
>- Make sure that nagios has been restarted since adding this group and
contacts.
Done. The contact groups in question have been in place for many
months.
>- Make sure you don't have multiple nagios daemons running at the same
time.
Done. Only a single instance is running.

[Nagios-users] Nagios did not send notification to some contacts
Hi All, I'm looking for troubleshooting suggestions to a problem we had. During a recent host down event Nagios sent notifications to 8 of the 18 configured contacts. The contacts are configured in two contact groups, of the 8 contacts that were sent notifications all were from the same contact group but there are another 4 contacts in that group that did not get notifications sent. No contacts from the second group had notifications generated. There was a routing issue on our WAN that caused this event, the SMTP server we use is across the WAN. Could the routing issue have prevented some of the SMTP notifications from being sent, wouldn't they just queue up and go once the problem was resolved? I have seen messages that did not arrive at the recipients phone but I've never seen Nagios not generate notifications for contacts that are configured for that host or service. Has anyone else seen this, any suggestions on a cause or how to troubleshoot?

Re: [Nagios-users] Checking URL on windows-client using NSClient++
Dennis,
Your almost there, you need to set your vbs script to output an exit
code of 0-4 according to the nagios plug in documentation
(http://nagiosplug.sourceforge.net/developer-guidelines.html#PLUGOUTPUT)
. Then setup the nsclient to run your script as a plug in check. To do
that you will need to follow these basic steps.
1. add the configuration to the nsc.ini file on each xp workstation you
want to run this check on. It should look something like this:
[NRPE Handlers]
webpage_check=c:\windows\system32\cscript.exe //nologo "c:\program
files\nsclient++\scripts\web_page_check.vbs"
2. Setup check in Nagios
In your commands definition file:
define command {
command_name webpage_check
command_line$USER1$/check_nrpe -H
$HOSTADDRESS$ -t 60 -c webpage_check
}
In your services definition file:
define service {
host_name XPhost01, XPhost02
service_description check web page on XP host
display_namewebpage check
check_command webpage_check
use service-template
.
}
That should do it, and it uses your existing script (i.e. no rework).
Good luck, hope that helps,
-greg

Subject: [Nagios-users] Checking URL on windows-client using NSClient++
Hi,
I would like to check if a certain website is available on some of my
windows xp clients. These clients are public self-service computers to
make bookings for a railway organisation. Every now and then, some of
these self-service computers show a blank screen without the default
start-page.
I would like to check if the page is shown up and if it's not, it
notifies Nagios which notifies me by email.
I've tried to run an external script (vbs) which checks the availability
of the site and that goes well if you use it manually but i dont want
any popups saying: "OK". It should run in the background. So i've edited
the vbs file and now it does check it and doesnt give any output
anymore.
Has anyone else tried something like this before?
I use NSClient++ and Nagios v3.0.6.
Kind Regards,
Dennis de Vries.

Re: [Nagios-users] disk IO for windows?
Hi All, We just started monitoring IO on our Windows servers. We measure two PerfMon counters (using the nsclient++ agent). System\File Control Operations/sec Description: File Control Operations/sec is the combined rate of file system operations that are neither reads nor writes, such as file system control requests and requests for information about device characteristics or status. This is the inverse of System: File Data Operations/sec and is measured in number of operations perf second. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval. System\Data Operations/sec Description: File Data Operations/ sec is the combined rate of read and write operations on all logical disks on the computer. This is the inverse of System: File Control Operations/sec. This counter displays the difference between the values observed in the last two samples, divided by the duration of the sample interval. I'm not sure what good thresholds are for these, currently we have a warning at 1 and critical at 2 on our test servers. We've had a couple of servers cross those thresholds but I don't have a good sense for what they should be yet. I've never seen any documentation regarding what a Windows box can do (in terms of IO). >From a command line they look like this: check_nrpe -H $HOSTADDRESS$ -c CheckCounter -a "\\System\\File Data Operations/Sec" ShowAll MaxWarn=1 MaxCrit=2 Regards, -greg -Original Message- From: Curtis LaMasters [mailto:curtislamast...@gmail.com] Sent: Tuesday, June 09, 2009 8:15 PM To: Anthony Montibello Cc: Andreas Ericsson; Nagios-users@lists.sourceforge.net Subject: Re: [Nagios-users] disk IO for windows?

[Nagios-users] Assigning contacts to hosts confusion
Hi All, Can someone help me understand the best way to assign contacts to hosts en masse? In version 1.x, we would create a hostgroup put the hosts that we needed in it and then assign a contact group to that hostgroup, done deal. Now it appears that under Nagios 3 to accomplish the same thing I have to create the hostgroup as before and then go to each host and assign a contact or contact group to it. That's much more tedious than the old way, am I missing something? Please tell me there's an easier way that I'm overlooking. I found this in the what's new in Nagios 2 doc's (http://nagios.sourceforge.net/docs/2_0/whatsnew.html): Contact group changes - The contact_groups directive has been moved from hostgroup definitions to host definitions . This was done in order to maintain consistency with the way service contacts are specified. Make sure to update your config files!

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).

[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? Thanks, -greg -- The NEW KODAK i700 Series Scanners deliver under ANY circumstances!

[Nagios-users] stopping and starting NDO daemon
Hi All, We've just setup nagios 3 using NDO (to support Nagvis) and I realized that NDO does not come with an init script. I found one post to the list (http://article.gmane.org/gmane.network.nagios.user/52477/match=ndo+init ) from about a year ago, someone was asking for help incorporating the NDO daemon into the Nagios init script, but there were no responses. I'm wondering how others are handling the stopping and starting of the NDO daemon? Would it be better to incorporate it into the Nagios init script or should it have it's own, has somebody already done this that is willing to share with the list?

When it comes back up you can keep SMTP primary. I'm not sure how to effectively check the "network" to see if SMTP is available, on one hand it seems straight forward but when I think about details it does not seem so obvious. My SMTP path looks something like this: Nagios -> local sendmail daemon -> smtp smarthost -> corporate smtp gateway -> corporate internet connection -> internet Maybe it's overkill to worry about all of those pieces but in my paranoid (i.e. mad boss wanting to know why we didn't know about a major outage) mind I don't want to leave anything out :-) Honestly I'm not checking all of those things now, but I would like to be a bit more thorough on the new setup, some of those things I don't have access to be able to check them. > How come you have to dial up each time to send alerts?

We do this using the NSClient++ agent (www.nsclient.org

them based on criteria you define, alerting when the number of hits you
specify is reached (i.e. when the system log has 1 or more events with

example we use to monitor for a specific Oracle error. In the example
we check the "application" log of the server every "60" minutes for
events with an ID of "20" with event type of "Error" containing a string
in the text of the message "Can not allocate log", check turns critical
after 1 matching event is found that is time stamped within the last
"65" minutes.

The NSClient++ data collector's primary mechanism for actions (getting
it to do stuff) is via NRPE. It will respond to the old nsclient
command as well but the majority of it's functions are utilized through
NRPE. This is the case with your situation as well. On the Nagios side
you would define a check like you have above and in the NSC.ini file you
define a handler for the command. Below is an example of one we use to
check the CPU utilization of any process on the server.
On the Nagios server define your service as above and use something like
this for the command_line line.
Command_line$USER1$/check_nrpe -H $HOSTADDRESS$ -t 60 -c
wmi_process_perf -a $ARG1$
On the Windows server in the NSC.ini file under the NRPE Handlers
section put something like this:
wmi_process_perf=c:\windows\system32\cscript.exe //nologo "c:\program
files\nsclient++\scripts\wmi_cpu_perf.vbs" /process:$ARG1$
In this example the $ARG1$ value is the name of a running process on the
server. The check returns the CPU and memory utilization of the
process.

Yes, as far as Linux/Nagios is concerned they are standard messages to SMTP addresses. >Have you verified that sendmail is behaving itself as a normal mail server on the Internet? It has valid public reverse DNS? Forward DNS matches reverse DNS? HELO name is a valid FQDN, preferably matching reverse DNS for the IP? What do your sendmail logs show? Is there a bounce generated? We use the same Nagios command to send successfully to the SMS addresses ([EMAIL PROTECTED] vs [EMAIL PROTECTED] for MMS) of the same phones (i.e. using the same SMTP servers to get out). The sendmail logs show the messages as being delivered Okay. I did some testing, I'm trying different things to try and discover where the problem lies. Test: Send 10 messages from old RH/sendmail box to MMS address of cell phone, Send 10 messages from new RH/sendmail box to MMS address of cell phone, Send 10 messages from windows box (with sendmail port) to the MMS address of cell phone. All messages are sent one after another from the command line. Results: Usually all 10 of the messages from the Windows box come through, though not always. Some of the Linux generated messages come through I've gotten as many as 4 and as few as none. The new versus old versions of Linux and Sendmail do not seem to make a difference. The messages will come through on occasion but not consistently. Not good for a monitoring solution. I should rephrase my original questions: Is anyone else using MMS to receive Nagios alerts? Do you ever notice any alerts not getting to your phone? What provider are you using?

[Nagios-users] A bit OT: sending MMS messages from Linux
Greetings All, My apologies if this is to much off topic. We are having trouble sending alerts from our Nagios server to the MMS address of our cell phones. We have been sending SMS messages for years with great success, however MMS messages are never received. We would like to use MMS because SMS messages are limited to 160 characters, MMS has a much higher limit. The problem is not with Nagios but instead (I think) with the sendmail mechanism it uses when sending messages. I'm just hoping someone on the list has dealt with this already and can help me figure it out. We use Sendmail to send massages from the Nagios server to an internal SMTP gateway that forwards the messages on to the Internet. We can successfully send MMS messages from Outlook clients on the desktop which use the same SMTP gateways as the Nagios server, the phones receive these without any trouble. We have tried both ATT and Verizon systems and neither will deliver the MMS messages from the Nagios server. We have also tested sending the messages from the command line on the Linux server. The common link between all the scenarios we have tried is the Linux server and the sendmail transfer agent. Does anyone on the list send messages to MMS addresses? If so did you have any trouble getting it to work, if not what OS and mail transfer agent are you using? We have tested this from Red Hat 7.3/Sendmail 8.11 and Red Hat Enterprise Linux 5/Sendmail 8.13 Thanks, -greg - This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Don't miss this year's exciting event.

Re: [Nagios-users] Monitoring Windows Servers - Comparing Options
>No input from anyone? One of the selling points to move away from proprietary solutions and towards OSS was the helpfulness of the community and mailing list. I know I don't have a 'problem' listed below that can easily be solved, but surely there are some opinions out there? Alright, I'll respond. Most of the time I usually just lurk here, most questions are usually answered quite well by others in a relatively short time. This is my 2 cents. See response below amongst your first post questions. >So, my question is, what is the best option for monitoring Windows Servers and why? >An important factor to consider is that I will probably not have Administrative access to any of the Windows Servers that I will be >monitoring. >I'm currently considering three options for the reasons shown below (in order of preference): >1) WMI checks >Pros >-Complete control of NRPE service on 'my' Windows Server >(Can this be distributed over two boxes?) >-Complete control of check commands on Nagios Server WMI provides a very thorough list of things you can check It's built into the OS, i.e. no install or configuration required >Cons >-NRPE service must be run from an account with access to all Windows Servers. WMI can fail. From time to time we have a server with WMI problems, we've been able to fix WMI at times, other times we've had to rebuild the OS, in those cases you would not have any monitoring. WMI is used by other things as well, and is susceptible to getting corrupted or reconfigured by something (or in our case someone) else. I think we've resolved most of our issues with WMI, however I learned that if it's broken, it does not matter why you can't use it to monitor anything until it's fixed. WMI requires common MS technology such as common MS network ports and Windows (AD) user accounts for security. This is not a problem for the most part but increases the risk when monitoring a DMZ for example and means your monitoring is dependant upon AD and thus anything AD needs (like DNS), etc. If AD or DNS goes down you've got bigger problems than whether or not your Nagios agents are working, however it that is how you watch everything then when they fail will you know it? >2) Agent checks - NRPE-NT or some other current Windows Agent >Pros Your not relying on a MS technology. Obviously the OS has to be available but your not dependant upon WMI or .NET or MDAC, etc. This may sound ironic but having your monitoring system as independent of the system it's watching as possible the better (IMO). Flexibility/Extensibility. For example the agent we use (nscp) (found here: http://trac.nakednuns.org/nscp - don't ask me about the URL I don't know why it is what it is - it seems safe though) is very flexible supporting both the original NSClient on the Nagios server side or NRPE and can check pretty much anything (including, WMI, perfmon, event logs, plus some built in checks and custom scripts). The documentation is not one of it's strong points, but it is very capable and reliable. I've struggled at times getting a particular type of check working because I could not understand the docs. I have not run into any problems with it in terms of crashes or memory leaks, etc. After about two years of using it (various versions) I can only think of twice when it has either generated an error or stopped running and that covers over 200 Windows boxes. It can be installed and uninstalled without server reboots. It just works, I like it. Better docs would be nice though. I'm not trying to sell you on this particular agent or even agents in general, this is my experience. >Cons >-Requires an agent setup and running on every Windows Server >-No direct control of agents/check commands Some checks via an agent (like custom scripts) are not as quick as SNMP (and probably WMI). >3) SNMP based checks >Pros >-Complete control over check commands on Nagios Server SNMP checks are very fast Once configured no changes are required on the server (i.e. SNMP does not require version upgrades, etc.) >Cons >-No direct control of SNMP Community Strings/ACL allowing access from Nagios >-No direct control of SNMP service The values exposed via SNMP on Windows servers is limited. You can do basic monitoring disks, ram, cpu, etc. But not advanced things such as CPU user mode vs. kernel mode usage. You can get an SNMP extension such as SNMP-Informant (http://www.snmp-informant.com/) to resolve this issue. SNMP can fail. We have a small portion of our servers both 2000 and 2003 where SNMP service won't stay running. We do some SNMP monitoring but not a lot, I've not solved this one yet. >How do you do it?
