Nagios Monitoring Server
May 19, 2007
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'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.

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?

My company has been having some issues with our email periodically but our host provides no help other than a graph showing the amount of daily relays.
Does anyone know of a good email server montior or diagnostic solution that works with MailEnable? Preferably something free or cheap.
I basically want to be able to get in and see what emails were sent and received from who and the IPs if possible. I don't care about seeing the content of peoples emails but just a report similar to a telephone bill would surely help.

I have about 40 servers that I'd like to stream stats to a windows computer (preferably a software based solution). It is a combination of linux and windows but I'd like to have as much stats as possible like loads, space, cpu usage, bandwidth usage, etc.

My dedicated server is sometimes sluggishly slow. I would like to get a grasp of its performance during a day, to get a better understanding of what's going on.
Therefore I am looking for a server performance monitoring service. All service I found so far were simply monitoring uptime (server is down / server is up). I need something more - a service that checks every 30 seconds or so the loading time of the main page.
Then it would allow me to download the data in CSV or draw a response time graph.
