[Nagios-users] Monitoring traffic
Hi, I'd need to keep traffic on a UMTS router monitored, i.e. I'd need to set up something that counts bytes passed and gives an alarm when a particular thresold is reached. The router gives no SNMP information about it. Is there any other way to do that with nagios? Thanks -- This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?

I think whatever you do is going to be a bit messy. It will probably
involve setting up two Nagios contact definitions for each physical
user (which is what I do in similar circumstances).
For example I would set up the contacts which your TEAM2 users log in
with to all have host_notification_options = n and
service_notification_options = n. I would then set up separate
contacts (for example if the user logs in with "Fred", set up a
contact called "Fred-notify". This 2nd contact can have
host_notification_options and service_notification_options = y.
You will then need to structure your contact groups so for example
contact group "TEAM2" contains user "Fred" and contact group
"TEAM2-notify" contains user "Fred-notify".
Those hosts you want TEAM2 to just see, you set contactgroups =
"+TEAM2" in the relevant host template.
Those hosts you want them to see and get notifications for, you set
contactgroups = "+TEAM2,TEAM2-notify" in the relevant host template.
Note that the user never has actually to log in using "Fred-notify" so
it doesn't need an entry in your htpasswd config - we only set that
one up for the notifications.
You might be able to do something a little tidier using a custom
notification script, but doing that might make your configs less easy
for anyone coming from outside to understand.
I hope that helps rather than confuses things for you!
Cheers,
Jim

Re: [Nagios-users] IP and hostname mapping control
We have a service that checks dns addresses. We run it against some of our
internal DNS servers (we're checking the DNS server is resolving, so the check
belongs on the dns server rather than the host you're interested in).
define service{
use infrastructure-dns-service
host_name dc1025,dc1026,dc1030
service_description DNS-myserver
check_command check_dns!myserver.com!4.5.6.7
}
define command{
command_namecheck_dns
command_line$USER1$/check_dns -H $ARG1$ -s $HOSTADDRESS$ -a $ARG2$
}
(I believe check_dns is a standard plugin)
So you'd have:
define service {
uselocal-service
host_name local.dns.server
service_description DNS resolving foo.mylan.com
check_command check_dns!foo.mylan.com!192.168.0.1
}

If you want to make sure that Nagios always records the text for a specific kind of check, you can set the "is_volatile" directive to "1". For services which normally report the same information each time they are checked this could be overkill, but for passive checks which are event-driven, for example SNMP Trap handling it is very useful. If you haven't already found it, it's worth taking a look at the documentation on volatile services: http://nagios.sourceforge.net/docs/3_0/volatileservices.html Cheers, Jim -- This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?

Re: [Nagios-users] Additional states in Nagios
Kevin gave a GREAT answer - succinct and yet informative. It sounds like he answered the first part of the question - clearing the ambiguity of the states. I interpreted the second part (the dream) as the desire to have Nagios differentiating between informational messages and things that perhaps require action (alarms). I don't think there is any single 'catch all' solution to this, I suppose it really depends on your environment, admin team, etc. For example, in your company, ALL alerts from S.M.A.R.T. disks might deserve immediate attention. In my world, we take the ostrich approach to those (just kidding, and don't flay me for perpetuating the myth of ostrich heads and sand). I personally use a combination of things to tune the alerts. For example, with printers alerting on low toner, I set the frequency of alerts to once every 24 hours, so as not to flood people with non critical messages. For disk alerts that come in as 'unknown' state, I have set the retry time high to avoid extra alarms getting sent just because network latency is high (thus returning the unknown state). I have also modified the plugins to strip out messages/states that are (to us here) strictly informational and not worth alarming on. And for any alert that comes in, you can always just 'acknowledge' it through the CGIs to hush it if it is strictly informational - it will alarm again (depending on your setup) if/when it changes state again (for better or worse). Lastly, though it is a TON of work, you can rebuild the entire alerting process. I store user preferences in a MySQL database and let the individual admins change those through a CGI. Then I send ALL Nagios alerts through that processor which matches up the alert, time of day, host, service, etc against the user prefs to decide who gets alerted and how. When you do something like that, you can then define alternative methods of alerting. For example, I get alerted on disks at warning level during business hours, but not until critical level off hours. In addition, I have the alerts just going to email during business hours, but I also send via instant messenger and to a home email address in off hours. You could use the same intelligence to split out what are strictly informational messages vs. what are real alerts. Ooops, I said lastly, didn't I? Another thought: maybe you could send all alerts to an Exchange (group) mailbox, and use Exchange rules to filter the informational messages vs. real alerts and send those on to individuals. Just my 2 cents. - Brent -Original Message- From: Kevin Keane [mailto:subscript...@kkeane.com] Sent: Monday, June 28, 2010 11:06 PM To: Nagios Users List Subject: Re: [Nagios-users] Additional states in Nagios Actually, there are four states reported by plugins: OK, WARNING, CRITICAL and UNKNOWN. Services will have the same four states. There are also three states that hosts can have: UP, DOWN, UNREACHABLE. UP, DOWN and unreachable depends on the state reported by the plugin, as well as the state of parents. http://nagios.sourceforge.net/docs/3_0/hostchecks.html HARD and SOFT states are separate from all of that. You can have a soft warning or a hard warning, and a soft critical or a hard critical. http://nagios.sourceforge.net/docs/3_0/statetypes.html OK, WARNING, CRITICAL and UNKNOWN are the actual state of whatever you are monitoring.

MinCritFree=$ARG3$
}
For my MinWarnFree and MinCritFree, I define a % to warn/crit for minimum
allowed space.
Can someone give me an example of a rrd template I would use for this so that I
can build off it?
It would be greatly appreciated, thank you.

Re: [Nagios-users] how to fix excessive latency
I am sorry for my bad english. My nagios server is not running in virtual server. Nagios3.2.0 + Suse10-sp2 x86_64 + 8 GB mem + 4 x ( Xeon(R) CPU E7420 @ 2.13GHz ), I think this hardware is enough. "I use vmstate to capture system performance", vmstate is a command in SUSE10,not a virtual server.

[Nagios-users] Modifying normal_check_interval breaks nagiosgrapher
Hi, While testing and deploying Nagios I used the following service definition: max_check_attempts 1 normal_check_interval 1 retry_check_interval 1 Everything was configured and tested including nagiosgrapher (rrdtool). It passed proof and concept and we have now moved it into production. We tested this against a small set of 200 servers. Then we went to our "production" values of: max_check_attempts 3 normal_check_interval 5 retry_check_interval 1 Data collection still works, but when we try to view a graph it's basically empty data (nothing drawn) for the period in which the new normal_check_internal was changed. If we change it back to 1 from 5, it starts to display data correctly again. How do I *keep* the new normal_check_internal value, but make it work again? Googling led me to this: http://forum.centreon.com/archive/index.php/t-4506.html which essentially says nagios.cfg:normal_check_interval and nrpe.cfg:step are tied together and if you change normal_check_internal you need need to lose all your data. The existing data isn't super critical. We're happy to lose it. I tried removing ./var/rrd directory (well rename) but then all the graphs broke with 'no such device' error. What other directories do I need to delete to clear all nagiosgrapher/rrdtool data? Cheers -- This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
