[Nagios-users] Transient errors
I see a lot of transient errors on services and hosts I'm monitoring. Hence finding ways to keep notifications from going out on situations that will resolve themselves are kind of an issue. I've played with how many failures in a row are needed to cause a notification, and have that set differently for things I'm monitoring across long links (Beijing, say) compared to things I'm monitoring locally or in New York. Of course, one problem with that is that it makes it take longer before a real problem causes a notification. Right now it takes over 15 minutes for the total failure of our link to Beijing to cause a notification. For things that are numeric values, I can play with the critical and warning ranges to potentially reduce false positives. That, at least, doesn't slow down recognition of total failures. Some things just don't seem to fit the Nagios model -- for example it's quite normal for the SQL server to pull 100% of the cpu for periods now and then, but if it goes on too long, *that's* unusual. Hmm; I suppose I could override the number of failures needed to cause a notification in the service definition for htose, couldn't I? There may be some things I should just stop monitoring (there aren't clear-cut "okay" and "bad" behaviors that I can quantify). I guess I'm wondering if there are useful basic approaches to handling this problem that I'm missing, or if I just need to work through the details more carefully. I'm startled at how often I get isolated failures for no apparent reason. Is that normal for most people monitoring services? I think I'm finding my connections time out now and then due simply to load, without the load actually being at all high. -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info -- Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ ___ 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

It's also probably fiddling around with small-percentage improvements, but I'm somewhat theoretically-minded, so the fact that it *can* go wrong and there might be a better way was bothering me. Anyway, that's what I was thinking about. Thanks for confirming that the check_command is what defines "host down", I thought so but wasn't confident. (Nagios documentation is pretty good as such things go, mostly when I get confused I eventually work out that what I had wrong was right in a not-too-weird place in the docs.) -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info -- Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ ___ 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

I hadn't thought of moving the check_command from the template into the host definition; I was instead trying to pass arguments through the template invocation, which apparently isn't supported. (And I had syntax wrong on passing args; I know better than that, I've written and used many other commands that need args, and passed them properly before.)

I'm thinking of using the router as a parent; if the failure isn't found by the check_command but only by one service failing, will that still cause the whole router host to be considered down for parent purposes? One goal here is to eliminate reports of multiple services being down from beyond the router, if the router itself (or the link) is what's actually down. Of course in many cases, the router is entirely cut off, so ping will also fail. The other thing ping doesn't catch is administrative screw-ups that mess up a port without shutting down the router (unless it happens to be a port that the Nagios monitoring has to go through). -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info -- Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ ___ 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] Where can arguments go?
I'm looking to use a special check command to verify routers are in
operation by checking the main link port of the router (instead of the
default ping). I'm running into confusion, because I need to specify a
port number in the host definition, and I can't really see how to do it.
I use soemthing like this for a template:
define host {
namesnmp-switch ; The name of this host template
use generic-switch
#check_command check-host-alive ; Default command to check if
routers
are "alive"
check_command check-snmp-switch-alive $HOSTADDRESS$ $ARG1$
$ARG2$
register0 ; DONT REGISTER THIS - ITS JUST
A TEMPLATE
}
I'm not sure the args on the check_command line are legal And I'm not
sure that arguments on a "use snmp-switch" line referencing this could
have arguments on them.
Is this a possible / sane thing to do? Is this the right way to approach
it, or am I missing a way that actually makes sense?

[Nagios-users] init.d/nagios
The init file built and installed by "make install-init" doesn't seem to work right. I apparently have nagios running after saying "service nagios start" (it reported success), based on receiving some notifications and on ps showing /usr/local/nagios/bin/nagios running as a daemon, but "service nagios status" reports "nagios is not running". (This is on a Centos 4.8 system, with Nagios 3.2.1 built from source.) I configured this version with "--with-lockfile=/usr/local/nagios/var/nagios.pid" after the previous version, without that, logged a permissions error when it tried to start up nagios. I suppose that could be the wrong fix for that problem, and hence causing this one. -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info -- Download Intel® Parallel Studio Eval Try the new software tools for yourself.

[Nagios-users] Host check timing
I'm monitoring some far-away remote hosts, that we connect to via the public internet (well, there's an encrypted VPN involved). I'm trying not to send notifications until an outage persists for a while. In an example I looked at this morning, I see that it was repeating the host check every 10 seconds until it hit the retry count. Where does that 10 seconds time come from? The manual is remarkably vague about host check scheduling; about all it says is that it does them on demand, and "If the first host check returns a non-OK state, Nagios will keep pounding out checks of the host until either (a) the maximum number of host checks (specified by the max_attempts option in the host definition) is reached or (b) a host check results in an OK state." Does this mean I have no control over the timing? Can I treat the 10 second observed delay as real (and then control total time delay by setting max_attempts high)? (Running Nagios 2.12 on Centos 5). -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info -- Download Intel® Parallel Studio Eval Try the new software tools for yourself.

[Nagios-users] check_snmp disk space monitoring
I'm playing with using check_snmp to look at disk space, with commands (working from the command line so far) like: /usr/lib/nagios/plugins/check_snmp -C public -P 2c -H localhost -o dskErrorMsg.2 -r '^\s*$' ([[:space:]] doesn't work any better than \s either) I'm trying to monitor the error message rather than the simple flag so that the data returned will include the error when one is found. I'm trying to use the regex capability to to match an empty error message; so that anything non-empty will be reported as an error. And I'm not getting anywhere. I'm mostly pretty good with regexps, but despite claiming in --help to support "extended regular expressions", it doesn't seem to. In particular the "^" for beginning of text and "$" for end of text don't seem to be working. Clues! Clues for the poor! Is this a basically stupid approach, by the way?

[Nagios-users] Monitoring a router
Not complex stuff; I'm not really monitoring the router primarily (that's another group's job), but I want some kind of check whether the router, and the connection it serves, are working or not (to use as a parent for other checks, so that I get just get notified that the router is down rather than every host and server beyond it reported down if the link goes down). Right now I'm just pinging it. That works, in the sense that I get the ping back. But I am suspicious that, if the link went down, the router would still respond to pings. Is this "best practice" in the opinion of the community? Or is using SNMP to monitor something inside the router better somehow? And if so, WHAT? One thing that comes to mind is IP-MIB::ipForwarding, which appears to be a boolean. I don't know if that indicates administrative state or actual condition, though. Should I be looking for some sort of interface state field instead?

[Nagios-users] Email service notifications not working
Or SOME of them. I did get ONE email service notification -- when I "acknowledged" a problem, I got a notification of that. But I got no notification of the change to critical status, and no notification of the return to normal. Service notification options are w,u,c,r. service notification period is 24x7. Service notification command is notify-by-email. Nagios 2.10 on Centos 4.8. I believe sendmail is configured adequately, because I can send a test email by hand, and because I've received that one service notification. Host notifications have generally worked on this install, though I haven't tested one lately. The web display is showing the service going into state critical, and it shows notifications enabled for that service. It shows "last service notification" as N/A, making me think that the problem is that Nagios isn't sending the notification, rather than any sort of delivery issue (and I've tested email from the monitoring host, works fine). This is a small setup, 13 hosts and 28 services, on a system with no load problems, so I'm not worried about performance issues being the cause. Everything is active tests form the monitoring system. How related are host and service notification? Should I test host notification at this point, or should I go ahead and work on service notification on its own? How do I approach this debugging problem? I'm assuming my config is at fault of course; but I'm running out of places to look. -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

[Nagios-users] check_http confusion / problem
Thanks to various list members for pointing me at various bits of documentation that I hadn't been able to find, which explain that commands can in fact take arguments, and that those and other useful things are called "macros". (I've been using macros since 1401 Autocoder, and mostly think of them as compile time code-generating tools.) So, what's with the check_http plugin? The parameters it accepts don't match the parameters its help says it accepts. But beyond that, the -e switch doesn't seem to do what it says it should. I'm not getting invalid results because I'm running from the command line, am I? This seems much the easiest way to test things, and it rather sounds like this is an intended use. But thought I'd ask just to be sure. In this case, the expected result of the test is a 400 Bad Request error (because I'm hitting a web services port and requesting root; this test is intended to do a minimal check and see that the service director is up, but not test the individual services yet). So the "400 Bad Request" response is correct and valid. Now, the -e switch seems to be intended to check just this status line, and to nicely short-circuit later processing, and seems in all ways optimized for exactly what I'm doing. Except for the minor fact that it doesn't seem to work. See below, run in verbose mode. I've tried a bunch of variants on the value I pass to -e, including the whole line given, and they all give the same result, an exit code of 2 and the "invalid HTTP response code" message. So what's up? And is there more documentation on the plugins hidden somewhere, particularly this one?

[Nagios-users] Why are there "commands"?
I don't really understand the purpose / utility of the "command" level of abstraction in Nagios configuration. (2.10; we're still on Centos 4.7). To define a new service to check particular Windows web services we've written, I define a service, and then it has to refer to a command, and over in the command I have to hard-code the parameters needed to test this specific service -- so in fact I need a separate command for each service. This seems, to me, to just introduce confusion, and separate bits of information that belong together. Is this just a historical artifact that in fact doesn't make much sense, or are there lots of cases where it's useful and makes it easier or clearer to do what you want? (I'm fine with "that's the way it works, but it doesn't really make much sense as it turns out", I've got plenty of that in my own code; I'm just looking for more understanding, in case it makes more sense than I've so far figured out.) As a broader question, are there documents that give more of a logical overview of Nagios, explaining how and why things are broken up and how they work together? -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

I have a bad history of failure to accomplish much of anything in at least three runs at using SNMP to get data from various devices, so I tend to shy away from the concept. It seems to be a horrendous learning curve, and none of the sites I've found so far make any *sense*. Having said that -- can you recommend a site that talks about SNMP and gives examples at the level of getting information out of a Linux box, and perhaps some sort of household router/WAP? It'd be good for me to learn, if I had some reason to hope I'd have a better outcome than the last few times. It does seem very likely that the simple things I need from Linux may already be in the MIB, meaning I just need to access stuff there rather than add anything new. -- David Dyer-Bennet, [EMAIL PROTECTED]; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

I will say that I got a command using one parameter working without any
trouble (and have since abandoned it for an approach making better use of
templates) yesterday. That example (well, the 2.10 version) was useful to
me.

Okay, I can work with that.
The --help output from the plugin, and I believe the website (but it's
timing out right now for me), gave an example using the ordinary "uptime"
service, and not a nagios plugin; and the text made no mention of the
thing run needing to be a nagios plugin. If it needs to be a plugin (or if
the vast majority of effective uses use a plugin) those docs should
probably be updated to reflect that!

Sure, I'm familiar with that. For command-line testing I'm relying on my
normal key and ssh-agent authentication, but I am planning to set up a
special nagios key that I can install, with limited command access, on
systems I need to monitor this way.

[Nagios-users] I don't understand the check_by_ssh plugin
I'm running Nagios 2.10 (the Centos 5.2 packaged version). I want to do some small local checks on each of a bunch of real and virtual servers, and I really don't want to have to set up Nagios (even a minimal install) on each of them just to check uptime, load average, and disk space. (Mostly I'm testing externally visible services on them.) The documentation on this plugin doesn't seem to tell me anything about what it does with the part of the command output it processes (I see that the -S and -E commands let me prune what command output it looks at). When I run it from the command line simply, I just get the output of the remote command (as if the plugin was just passing it through). I see that I could cause it to produce errors based on how long it takes, but nothing about how to actually use the output. Then I see some tantalizing hints about "passive" mode, where it writes a file that seems to show it doing some parsing and making decisions based on the data (in the example). But I can't get the example to produce a non-empty file from the command line. So I'm pretty sure I'm missing something about how to use this plugin in the first place, or what it's supposed to let me do, or some such. Or, if the answer to what I'm trying to do is some other approach entirely, I'd settle for enlightenment about that!

[Nagios-users] Confusing error message

In this segment of log, it says I have an invalid "retry_interval" possibly; then, when I add one (there was none), it says that "retry_interval" is an invalid directive. I'm assuming that reading the config docs will tell me what the real name is, this is just a grouse about the incorrect error.

[Nagios-users] Testing the configuration
Since the top configuration file, at least in the examples I have, gives absolute paths to the other config files it specifies, it makes it hard to test a configuration before putting it into production (short of a separate test system, perhaps a virtual one). Are those absolute paths needed? The doc gives examples showing absolute paths, and doesn't talk about what a relative path would mean (but doesn't say it's forbidden, either). Are relative paths allowed? Can we predict what they'd be relative to?

[Nagios-users] Where in the docs...
...could I find information on macro definition and substitution? Comments in various places describe "$HOSTADDRESS$" as some kind of macro substitution, and other examples show multiple sets of parameters in somewhat strange syntax in service invocations (and refer to $ARG1$ and such), but I haven't found where these things are actually documented or explained at all. I've been able to write a number of new service, command, and a couple of host definitions, even some that use parameters, and they work, which is nice (and even useful, already), but I need to understand macros more; are they pre-coded, which ones exist, and so forth. I'm sure the way I'm doing things now is repeating things a lot more than is necessary (yes, I've looked at the tip for multiple hosts with the same services, etc., and I do understand at least some of them). -- David Dyer-Bennet, [EMAIL PROTECTED]; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
