Private Server For Nagios
May 20, 2008
I'm trying to find a hosting company or private linux server that will host an installation of Nagios which is a monitoring utility. It does require some linux system packages to be installed as well as a break in the firewall for the monitoring.
Does anyone know of cheap linux private server (less than $25/month), or is anyone else running this with someone? It really requires no memory or hard drive space and I'm sure could run in a less than amazing CPU environment. It generates pretty constant web traffic but very low bandwidth.

I'm thinking of purchasing a server that will monitor about 50 different servers using Nagios. It would probably just run Apache and nothing else but i was wondering if anyone has experience setting up a Nagios server just for monitoring other boxes on a network.
I'm wondeirng if this can be done. I will be monitoring a few customer servers but would like to give those customers access to Nagios and access only to their servers and nobody elses. Is there a way to setup Nagios so certain users can view their own boxes and nobody elses? Probaby setting up some type of group configuration. What about alerts? If a customers box goes down they would need to be alerted. Does Nagios allow those users to receive alerts specific to their boxes.
Not even sure how powerful the server should be. Probably a Celery or something a bit more powerful should do.

I am currently with the planet and am happy with them, however as part of a new venture I need to gather a list of hosts as well as the planet that will be able to cater to the ventures needs and go to tender with the requirements.
ThePlanet offer something called a virtual rack. This is cheaper than renting a dedicated rack, allows for Gb networking but doesnt not allow for a SAN. Do other providers offer something similar? The cost of putting a machine on the virtual rack is not that much more expensive than just renting the machine. I guess there isn't too much to these set-ups to be fair.
If not, then we are looking for dedicated racks, with the ability to host a SAN at some point, but starting off with say 3 servers (2 web servers, 1 storage server with raid5 6Tb of hdd). These servers will be dealing with network cameras although I don't think that many will be streaming at once but the network capacity does need to be there.
Who's door should I be knocking on to find out some prices?
One final thing, should I bother looking for co-lo providers as well? We are in the Uk but not precious about our host being in the same country at all (it would be nice but uk prices are ££). Really, all we would be able to do with co-lo is buy the hardware outright to save price as we are not interested in looking after the hardware.

Using the current version of Nagios, Nagios plugins, and NRPE. Trying to get monitoring of a remote server working. I have other monitoring services functioning, HTTP, POP, FTP, PING. Trying to use check_nrpe.
Monitoring Server from command line I run:
/usr/local/nagios/libexec/check_nrpe -H xxx.xxx.xxx.xxx -n -p 5666 -t 30
and it returns:
CHECK_NRPE: Error receiving data from daemon.
Also I have tested "/usr/local/nagios/libexec/check_nrpe -H localhost" on both Monitoring and Remote server successfully. Then changed the ip in the /etc/xinetd.d/nrpe back and reloaded xinetd.
On the Remote server, in the messages log I am getting the following:
Jan 20 22:54:44 XXXX nrpe[8186]: INFO: SSL/TLS initialized. All network traffic will be encrypted.
Jan 20 22:54:44 XXXX nrpe[8186]: Error: Could not complete SSL handshake. 1
This is strange because I turned off SSL using the -n option in check_nrpe command.
I can successfully Telnet into the remote server with "telnet xxx.xxx.xxx.xxx 5666", so I know it is not a firewall issue on the remote server. By the way, both servers have openssl-0.9.7a. What am I missing? Can I compile nrpe with no SSL support, and if so how can that be done?

I have configured Nagios on my network 10+ Servers (Linux+Windows) now when i check through http://localhost/nagios everything is ok but only ping command is giving following message :-
Unknown
bin/ping -n -U -w 10 -c 5 x.x.x.x
CRITICAL - Could not interpret output from ping command
and mail me "server down " message
So what is the issue ?
I am able to run this command through command line
./check_ping -H {server} -w 100.0,20% -c 500,50% -p 5
PING OK - Packet loss = 0%
./check_ping -H x.x.x.x -w 300.0,80% -c 500.0,100% -p 5
PING OK - Packet loss = 0%

Anyone know of a monitoring package that is essentially Nagios and Cacti in one? Nice SNMP capabilities, but still basic service checks (smtp, dns, web with host, etc), and some nice reporting?
Most reporting packages I've looked at seem so overly complicated with confusing/cluttered UIs and lack plain simplicity.
All I want is to monitor these servers, use SNMP for RAID status, disk space, CPU, etc, and verify connectivity to its services and each website. Is it asking too much? I've been using Cacti and Nagios, but separately and I'd really like something that combines the two of them.

I'm trying to use the check_time Nagios plugin to see the Time/Date/GMT but this is not possible because the servers is not abled to receive connections on the port 37, see the plugin output:
[root@fireslayer libexec]# ./check_time -H 189.1.169.70
Connection refused
TIME UNKNOWN - could not connect to server 189.1.169.70, port 37
[root@fireslayer libexec]# ./check_time --udp -H 189.xxx.xxx.xxx
TIME UNKNOWN - no data received from server 189.xxx.xxx.xxx, port 37
[root@fireslayer libexec]#
Without the --udp the plugin try to connect on port 37 with TCP protocool

We wanted to put up a nagios server for monitoring around 9 - 12 servers and couldn't find any real specs on what kind of machines are required for nagios.
Any leads on what kind of machines would do? My concern was the RAM requirement - if nagios works well on low end machines, it may make sense for us to host it on some VPS.
Wanted to check in with people who run nagios installations and their experiences.

We are currently using Nagios and really liking it! But ran across Centreon which is apparently based on the Nagios core. Any one have any experience with it? Any pro and/or cons of either system?
Also from a desktop monitoring standpoint, anyone have a preference to monitor software? A1Monitor vs. PortSensor or is there another one you would recommend. This is all for monitoring Linux boxes and looking at systems/software that provides alert notifications.

I want to configure Nagios to monitor Windows and Linux servers and their services. I have to install NSClient in Windows servers and NRPE in Linux servers to collect the data. I don't want to install any plugin in any server. Is there any guide available which describes how to enable Monitoring of servers using SNMP through Nagios?

I am wondering what services it is best to monitor with Nagios which I've installed on my Centos 5.3 VPS. I wish to monitor and understand all essential services of the VPS itself at this stage but, generally, to make the best possible use of Nagios as an analytical tool as well as basic monitoring notifications, etc.
I already have a rough idea based on the main services being run. But I imagine there may be more to this than meets the eye, in particular, in view of any potential performance cost, etc.
I am especially keen to obtain as detailed a picture as possible concerning performance related criteria with a mind to indicating possible improvements that could be made.

Even though I have set notification_interval from 120 to 120m. It might take the changed interval_limit from nagios.cfg.
I am receiving far too many e-mails and text messages in case of downtime at the moment. We're testing our monitoring servers at the moment, but we don't need a new notification every 25 minutes...

We are starting to use Nagios for some remote service checks (http, smpt, pop, ssh, etc..) and the notifications are not being sent out. We have the regular hosts configured and those are being sent out just fine.
Here's what we have currently:
Part of our services.cfg looks like this:
Code:
#### Generic services template ################
define service{
name generic-service;
active_checks_enabled 1;
obsess_over_service 1;
check_freshness 0;
notifications_enabled 1;
event_handler_enabled 1;
flap_detection_enabled 1;
retain_status_information 1;
retain_nonstatus_information 1;
register 0;
}
define service{
use generic-service
name basic-service
is_volatile 0
check_period 24x7
max_check_attempts 15
normal_check_interval 5
retry_check_interval 1
notification_interval 20
notification_period 24x7
register 0
}
define service{
use basic-service
name dns-service
check_command check_dns
max_check_attempts 10
check_period 24x7
notification_interval 20
notification_period 24x7
notification_options c,r
contact_groups localadmin
register 0
}
#### HOST01 ######
define service{
use dns-service
host_name host01
servicegroups mygroup
service_description DNS
contact_groups localadmin
}
To me, that looks correct. Host01's service check should inherit
everything through 'use dns-service' line.
checkcommands.cfg file for DNS:
Code:
# 'check_dns' command definition
define command{
command_name check_dns
command_line $USER1$/check_dns -H $HOSTADDRESS$
}
contactgroups.cfg:
Code:
define contactgroup{
contactgroup_name localadmin
alias Site Administrator
members nagios
}
contacts.cfg:
Code:
define contact{
contact_name nagios
alias admin
host_notification_period 24x7
service_notification_period 24x7
service_notification_options w,u,c,r,f
host_notification_options d,u,r,f
service_notification_commands notify-by-email
host_notification_commands host-notify-by-email
email mail@domain.com
}
I believe the above should be correct since I have host and service to
be notified by email. Obviously I'm overlooking something.

I'd like to set up my server as a proxy for my own private use, where in my home PC's browser I can tell it the server's IP, port, and the password that I set, and it will function like a normal proxy. How can I do that? What software do I need and so on.
All my servers are on Linux machines.

how you are doing this if you are co-locating a few servers in the same rack. I'm looking at putting in a small server to handle the backups offloaded to it, and connecting the 2nd 1Gbit ethernet ports on our Poweredges to a private switch. Does this sound about right and how you would handle them?
We already do offsite RSYNC, what I am trying to work out is how to handle backups held onsite from multiple servers. The servers will have a local copy of a backup, and i'm thinking one offloaded to a specified backup server. That backup server can then RSYNC offsite.
Right now we have two 1RU servers, with two more going in and a 2RU server. So ideally I would like to backup all 5 servers to this box.
Perhaps i'm over complicating it? However I do want to have a good backup system in place, I sleep easier at night this way

Got a person potentially developing an ecommerce website for me. Part of the agreed price is 1 yrs free hosting on their server. However what are the pitfulls since i am concerned with security (customer credit info), and if anything untoward happens like the site going down.
If a proper webhosting business is required, essentially i need these:
"Linux server with PHP, MySQL, an SSL certificate, register_globals turned on, a c-panel to admin the MySQL"
Which provides a great qualty and cheap service (not godaddy) - if it helps I am bested in the UK.

I am "simply" looking to run a Joomla! community site with an estimated 250 - 500 and then eventually up to 1,000 users onine at one time. The main attraction will be the user forums and profiles. I don't plan on having any videos or anything like that, but I will install a mambot that will integrate Google Video, etc.
I am trying to pick a VPS provider and from what I have read so far, I have kind of narrowed it down to a few places:
Spry.com
vpslink.com
knownhost.com
mediatemple.net
From reading alot so far, I would imagine I would need at least 256-512MB of RAM. Plesk sounds like a good control panel since I won't be reselling any of the space. Webmin sounds too hands on, and I know a little bit, but not a lot. The backup option that comes with Spry.com sounds tempting, but VPSLink has attractive price points. Mediatemple.net also gives you 1TB of bandwidth, a very attractive option.
I am "simply" looking to run a Joomla! community site with an estimated 250 -
As long as the site can run MySQL, I am happy. Joomla!, statistics software (any suggestions) and WordPress and that is about it as far as applications.
Any suggestions on what plans or who I should go with? My budget is about $t50 a month.
