More-specifically?

Are you notifying from your central and forwarding / submitting passive
checks from your slave?  Does your slave self promote?

Are you running a centralized config file system?

Are your nagios-plugins version different?

Virtualization is a requirement in many environments.

High Availability / Multi-Facility redundancy is a requirement in those
facilities as well.  

A properly deployed Nagios will have a self-promoting standby slave that
in another facility that will take over the notification role and inform
contacts about a failed master VM / Hypervisor.  ~BAS

[Nagios-users] nagios and ec2

2008-06-14 Thread Novak Joe
Hi,
 I'm interested in setting up nagios for use with amazon's ec2 service.  A
quick search of gmane did not turn up any results for the term 'ec2' in this
list, but I wonder if anyone has experience using it with aws.

I am interested in running nagios as part of an autonomous decentralized
system, such that in effect every host in the system is running nagios and
everyone is checking up on everyone else, albeit with the monitoring details
varying slightly depending on the host type.

Is this feasible, does it make any sense?  From what I've read so far it
seems like nagios was not designed and is not widely applied to this kind of
usage scenario, however from a cost perspective it is preferable for me to
run nagios on every host I have up, rather than paying for a minimum of 2
additional hosts which are completely dedicated to nagios and monitoring.

You seem to have missed the point. A VmWare system is known to be less
accurate with the clock. So your nagios installation on top of that may
suffer from that.

Ghost may be nice for those XP images. But if you know what you changed
then you know what to backup.

I have two servers that have a backup user on each and I use rsync+ssh
to backup config files and such on a daily bases to the other server.

I think most of us have not read that book. So you need to be more
specific with your examples.

What happens if you execute the command by hand?

But you should not use duplicate entries. I think NRPE should actually
reject it and/or fail to startup.

[Nagios-users] check_mysql_query

2008-06-14 Thread Kaushal Shriyan
Hi,

I want to set a nagios alert whenever the count(*) of a specific table in
test DB (MySQL) on a specific host crosses 20 using mysql_check_query
plugin

I have referred to http://nagiosplugins.org/man/check_mysql_query for -w and
-c option
which says -w, --warning=RANGE Warning range (format: start:end). Alert if
outside this range
-c, --critical=RANGE

How can i set this in nagios(nrpe.cfg) on the remote host.

Any example would be really helpful

I have set it like the below in the nrpe.cfg file

command[check_mysql_query]=/usr/nagios/libexec/check_mysql_query -q "Select
count(*) from table" -w1:5 -H localhost -P 3306 -d test -u test -p example
command[check_mysql_query]=/usr/nagios/libexec/check_mysql_query -q "Select
count(*) from table" -c20 -H localhost -P 3306 -d test -u test -p
example

Not sure if the above command is right.

Any ideas

Thanks and Regards

Kaushal
