I *think* I might have written a partial, device-specific implementation of it once, a long time ago. AFAIR, it's a fairly simple binary protocol along the tried and tested variant of head+body. I'll have a look at work tomorrow and see if I can find it. If so, I can most likely post it here.

Well, count me in as another happy user, at least as far as the configure part of the process goes. I ran into the same issues running configure on OpenBSD 4.1, and that fix worked.

Here is my rough idea, and you can decide if it adequately meets your needs. (I'll call the two Nagios installations Nag_A and Nag_B.) 1) Nag_B monitors the datacenter. The service check on Nag_B never sends notifications, it just submits passive check results to Nag_A. 2) Nag_A also monitors the datacenter. We'll call this service DC_A. It also has a service called DC_B which never performs active checks (it just gets the passive check results from Nag_B). 3) A service dependency is defined so DC_A depends on DC_B, with the "notification_failure_criteria" option set to "o". If I understand service dependencies correctly, when DC_B is OK there will never be a notification (regardless of the state of DC_A). Only if DC_B is non-OK and DC_A is non-OK will a notification get sent. -- Rick Mohr Systems Developer Ohio Supercomputer Center - This SF.net email is sponsored by: Splunk Inc.

Well, an example command definition (which assumes $USER1$ points to
your plugins directory) would be:
define command {
command_namecheck-host-alive
command_line$USER1$/check_icmp -H $HOSTADDRESS$
}
But it depends on how you want check_icmp to behave, of course. See
"check_icmp -h" for the available options.

[Nagios-users] Modbus/TCP??
I'm looking to take my monitoring of a transfer switch to the next level beyond just dry-contacts. The switch manufacturer offers a monitoring card that is TCP/IP capable, but it does not expose the various things it monitors over SNMP, but instead uses ModBus/TCP. I've not run into that format before, but I gather it is, or is rapidly becoming, the standard communication protocol for similar devices. Has anyone come up with a Nagios plugin that works with ModBus/TCP?? Unless I'm just not searching for the right thing, Google has been of no help at all.

It was designed to run small programs that perform a limited task quickly and then react on the outcome of the execution of that small program. If you put nagios to use for a different purpose, it will ultimately perform less excellent. > Which other Nagios's tasks will be delayed? > That would depend on how nagios designs your scheduling queue. If it's a host-check that's expected to take several minutes, nagios 2.x and earlier will stall exactly everything while waiting for the check to finish. If it's a service-check, only the other services that happened to end up in the same batch will be delayed, but only wrt the reporting back to the main thread. -- Andreas Ericsson [EMAIL PROTECTED] OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 - This SF.net email is sponsored by: Splunk Inc.

This can quickly become troublesome though, as the keys and commands mount up (maintenance nightmare, but very secure). For routers and switches, SNMPv3 is almost always the best way to go. Personally, I prefer NRPE since it also allows event-handlers to be added without having to install additional software. The code is also small, and I've audited it myself so I know it's sound, provided it's configured properly. -- Andreas Ericsson [EMAIL PROTECTED] OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 - This SF.net email is sponsored by: Splunk Inc.

In this case, 126 *usually* means "ENOPERM", an error you'll see if a program tries to execute a file that doesn't have the execute flag set, or if the user trying to execute the program lacks the permissions to execute the given file. Since the OP stated all the plugins are owned by the nagios user, I'd assume a simple chmod +x /path/to/nagios/plugins/* would suffice. -- Andreas Ericsson [EMAIL PROTECTED] OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 - This SF.net email is sponsored by: Splunk Inc.

The best solution would be to have a neb-module that communicates check- results between the two nagios-servers. When a check is about to be sent, have the same neb-module check the status on that secondary nagios-server and block the notification if either one reports the host as up. This way you'll get an additional minor delay before receiving a notification, but since you can force a check on either nagios from within the module whenever the second server reports a failure, it should be a very minimal one. Hacking up such a module should take about a week, assuming whoever does the work is well-versed in C and has a decent grasp of nagios' internals. A second option is to let an event-handler report the checkresults to the other server and adding them to a list of some sort (database, flat-file, whatever) and then modifying your notification script to only actually send notifications when both the servers report something as down. Assuming you use "notification_interval 0" for all your hosts and services, only the server that does the last check of whatever host/service it should report on will send a notification. This shouldn't take much more than a day to hack up, but is less elegant. With a shared network-capable database it shouldn't be too much trouble though. There are more options, but those are the two elegant ones I can think of. -- Andreas Ericsson [EMAIL PROTECTED] OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 - This SF.net email is sponsored by: Splunk Inc.

[Nagios-users] notification interval is 4325420??
hi all
I have a problem with nagios 3.0b1. when I check my config via web
interface with "view config -> service escalations" in the column
'Notification Interval' it shows 4325420. I don't understand from where
that number comes... either I have hit a bug or I'm doing something
really wrong.
the config lines which produces that looks something like
define serviceescalation {
host_name a-test
service_description tcp_5556
contacts oncall
contact_groups
first_notification 2
last_notification 0
notification_interval 5
}
(contact_groups is empty because i want to override the inherited value)

[Nagios-users] nagios threads and process model
Hi List, Where can be found some information about Nagios threads and process model: * How many threads are running? * What are their main tasks? * Are there some threads that are starting doing some work then terminating? * What about the process model (parent/child - fork) - When fork is done? How it relates to the threads model? Is there any documentation about those issues? Can someone give here some light? This information can help understanding what is reasonable to do and what is not. For example assuming that process_performance_data is enabled then service_perfdata_command is called periodically, Nagios uses perfdata_timeout which is by default 5 seconds to wait for the command and if hasn't finished it will be terminated. If there is some work that might take in the command much more time e.g. 1 minute, is it reasonable to it in this command and let's Nagios to wait for it 1 minute? Which other Nagios's tasks will be delayed? Thanks in advance, Yishai. ** The contents of this email and any attachments are confidential. It is intended for the named recipient(s) only.
