Hello everyone,

Is there a way maybe through a nagios-plugin that would allow you to get traps off of an astaro firewall? for example if the firewall reach a certain amount of bandwidth get a nagios notification etc.

Thanks for your help.

Manually run custom command via nagios dashboard possible?

I'd like the nagios dashboard to allow me to run commands MANUALLY when I see there is an issue.
For example, when a service goes into the 'CRITICAL state' I would check the dashboard and do a sanity check by looking at the performance output and perhaps even log onto the machine. I'd like to keep the dashboard open and click a hyperlink that executes a command that I choose on the remote machine.

I know there is the concept of event handlers which can AUTOMATICALLY execute a command when a service check returns a failure, but I'd prefer to do this type of healing manually.

Does nagios offer an ability to run a custom command/script I choose via the dashboard?

Thanks

passive check always Pending

Hi all.

 

I supposed to use “initial_state” parameter to see a particular state waiting the first output from a passive check, but it is still in pending state.

 

How can I solve it ?

Must I use other parameters together it?

 

I can’t use the check_dummy active command because it deletes the error before it is really solved…I disabled active checks

 

Thanks

Marco

Monitoring shared filesystems

Dear fellow Nagios users,

We have a bunch of servers on which we have shared filesystems.  The filesystem actually resides on the SAN storage and are connected to physical servers.  Let's say /home is shared among server1 and server2.  When /home breaches the WARNING or CRITICAL threshold it raises two tickets, one from each server.

I tried utilising the check_cluster and check_cluster2 plugins to raise only one ticket when there is a problem instead of two.

I have the following definitions...

"Disk Monitor /home" is being monitored on server1 and server2 using NRPE with notifications disabled.

hostgroups
==========

define hostgroup {
        hostgroup_name                 clustered_servers
        alias                          Clustered servers
        members                        server1,server2
        }



servicecluster.cfg
==================
define service {
        service_description             Clustered disk /home
        hostgroup_name                  clustered_servers
        check_command                   check_cluster_service2!$SERVICESTATEID:server1:Disk Monitor /home$,$SERVICESTATEID:server2:Disk Monitor /home$
        max_check_attempts              3
        check_interval                  2
        retry_interval                  1
        notification_interval           15
        contacts                        sysadms
        register                        1
        }


It seems when the hostgroup_name expands internally in Nagios it creates two service checks in both the servers so it is understood that there will be two alerts.  What changes can I make to raise only one ticket?  In certain cases we have around 10 servers with shared filesystems, so you can understand the havoc it creates.

Please let me know if you have any questions.

Thanks,
Ashish

High Service Check Latency

Hello!

Yes, it's a common problem, but cannot figure out how to debug it.
I've a distributed setup with a master server collecting >9.000 passive services sent from other 
servers, all with active latencies near 0. The master server checks *only* itself as active 
services, ~40 services, most of them every 5 minutes. AFAIK passive services should not affect 
"active service check latency" statistics. Looking into retention.dat file, the high latencies are 
all related to the local executed active services. Actual stats:

If I force a schedule of an active check, I can see how the force is immediatly logged into 
nagios.log, but executed with the high delay.
Is there a way I can debug or what parameter should I tune? Increasing logging could help?
I've still looked on the nagios tuning page, but doesn't help me much. Some suggestions based on the 
information provided?

Thank's a lot!

Nagios - can it send email when leaving a service comment?

I'd like nagios to send an email after I leave a service comment through the web dashboard.

The purpose of this would be that it would send a mail to the contact list that someone is working on the issue at hand and to track this information over time (how long it takes to resolve and issue and what the solution was and so forth).

Is support for Nagios being able to send a mail when leaving a service comment built in?

check_procs and negating regex in --ereg-argument-array

All,

	Is it possible to negate the regular expression used in
--ereg-argument-array with check_procs?

	We want to ignore one of the processes running on a machine but when we
try to use negative lookahead the regex is not processed correctly
because it reads ! as a bash internal command:

./check_procs -w 25 -c 35 -m CPU -v --ereg-argument-array=^((?!john).)*$
./check_procs -w 25 -c 35 -m CPU -v --ereg-argument-array=^((?john
--show passwd.ldap).)*$
bash: syntax error near unexpected token `('

	And the Nagios web output shows: NRPE: Unable to read output

	Does anyone have any suggestions?

Best Regards,
Camron

does monitoring stop while nagios is flushing queued items?

Hi all,

My installation is centreon + nagios.
Sometimes I need to do maintenance on mysql so I stop ndo2db and let nagios cache the result first.
And when I start ndo2db, nagios will start flushing the items.
I notice from the service perf data file, the data stops coming (or nagios not polling new data) while nagios is flushing queued item.

I just want to confirm whether it is the behavior of nagios? If yes, any workaround for this?

is Multiple instances of broker_module possible?

Hi All,


Since I'm having a constant database crash with my centreon+nagios installation, I'm thinking to run 2 brokers, each feeding data to different servers.
is running multiple instances of broker_module possible?
