Apachetop / Munin / Nagios - Best Way To View Apache + Other Service Activity
Nov 12, 2008
On Cpanel/WHM. I have just moved from a VPS to a dedicated server. I reinstalled munin, so get some stats via that. I used to have apachetop loaded on my VPS for when I wanted a 'near realtime' streaming view of apache access.
I'm wondering what the best solution is to get a good view of apache, like what apachetop did, plus also it would be nice to have a real-time monitor of MySQL activity, HDD activity (such as I/O queues, etc. Something along the lines of the perfmon on Windows servers.
What is my best option?
Also, with Nagios, when I look at the website, it seems there are two options. Load it on a single server and then load the stats via [url]or have the Nagios 'stat collector' on one machine, and have it gathering stats from multiple machines.
If you only install it on a single dedicated server, do you really have to be on the console and connect to the Nagios stats via localhost, rather than connecting remotely?
Ideally, I would like a quick, easy to setup solution, but if it takes some configuring, I can deal with it, as long as there is some documentation. My main goal is to get the real time type monitoring, you get with window's perfmon.

What's the best way to monitor apache in as close to a live manner as possible. I am hoping to get something similar to Top that would show the current number connections, maybe the URL being hit and other stats of that nature.
I know I can use mod_status (either via WHM Apache Status) or outside of it, but that has to be constantly refreshed (manually or automatically) and creates GET /whm-server-status?refresh=60 HTTP/1.1 entries that kind of skew the stats, depending on how often you refresh.
Is apachetop a solid choice? Any downsides?
Is there a better tool to have a 'live' view of apache's activities?

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 just installed Plesk 12 Web Admin Edition, installed and activated all licence keys and everything works fine.The only thing, I can't find the "Service Provider View" in the Interface Settings, there is only a "Power-User" view provided, even I've selected the Service Provider View during Plesk Setup, I was moved to the Power User view and now I can't switch the interface.I am really missing the server health monitoring from this Service Provider View like got it on all other servers I have.

Running programs named Perl with Heavy CPU usage, with the ownership of user apache.
We found the problem on Fedora 3 and Fedora 6.
In our case, it was the result of a Trojan activity.
Quick Solution
Check the cron jobs of user apache
crontab -u apache -e
*/1 * * * * perl /tmp/.tmp/tmpfile
delete the cronjob entry.
Also delete the file /tmp/.tmp/tmpfile
also added "apache" to the file /etc/cron.deny
That's all
Problem and solution in detail....

We are unable to change the view to service provider in plesk12. Only power panel seems to show up.
Tried to do a bootstrap repair but that hasn't fixed it.

I'm trying to get setup with Apache 2.2, and did just fine on one server but the second one is giving me some troubles. I'm having an issue with some sites wanting to download instead of display. Does this ring any bells with anyone right off?
httpd.conf appears to be okay as far as I can see, but obviously something is not quite right somewhere.

I installed Apachetop on one of servers. Installation went fine, but when I run it, nothing is displayed. No data, no stats. I see only blank screen with these details:
last hit: 00:00:00 atop runtime: 0 days, 00:00:00
I left it running for about 10 minutes, and still no output is displayed. There is CentOS 4.4 installed on server.

my Windows 2003 server is showing a very steady amount of action on Port 1028 and Port 135.
The Process is listed as "Unknown" with a PID of 0
The Local IP is 127.0.0.1
The Remote IP is 127.0.0.1
The Remote Port is either 1028 or 135
The State is "TIME_WAIT"
The Protocol is TCP
The path to the executable is blank. At any given time there are at least 20 active processes of this. The virus scan says all is well.

Does CentOS4 logs every activity done by a SSH user? Or is there such script/software to do that?

I am interested in setup user activity limits to avoid peaks on the server load, I have readen a lot about PAM and limits.conf but still have no idea on how set this limits. Most of the examples are similar to this page http://www.seifried.org/lasg/users/ but they are still confusing to me
>> I would like to setup rules like this:
Customers may not use more than 2% CPU daily, 3% memory daily, run more than 10 simultaneous processes per user, allow any process to run for longer than 30 CPU seconds, run any process that consumes more than 20% of available CPU at any time, or run any process that consumes more than 16 MB of memory.

Last week, we received a letter [url] from Companies House (the UK entity which governs companies).
It was addressed to Exoware, with all the correct contact details, reminding me to submit statutory documents by a certain date or face a fine and/or prosecution.
It was sent to us, because apparently, Exoware is a director of Jarhosts limited. This is not true. We have never even heard of Jarhosts limited up to this point, but it appears they had ceased trading by the time we received the letter.
A few emails were exchanged between us and Companies House, which didn't really get us anywhere as they couldn't seem to understand our position, so I phoned them up myself. I got through to someone and explained our position and she informed me about the company and said they registered Exoware as a director of Jarhosts limited on 05/12/08 and they themselves promptly resigned from the company afterwards, so Exoware was the only remaining director.
After I declared that Exoware had no affiliation whatsoever with Jarhosts limited, she promptly forwarded the case to a department for dealing with fraudulent documents and said the company will dissolve soon and that we may hear from Companies House fraud department in the future.
So, my concerns are now at ease, but my curiosity still remains.
Does anybody know Jarhosts; how long they were around for, who they were owned by, or any relevant information about them? Or does anybody know of any reason that people would sign up a random business in the same industry as a director before bailing out of their own company? It all seems very obscure.

what to look out for in the log files, but a couple of things jumped out at me over the weekend:
I had 5 of these, I followed the link (I suppose is the referrer) but it takes you to a polish-hosted russian webpage that tries to infect your browser. So DONT VISIT THE WEBSITE unless you're virus checker is fully up to date!
Code:
shop.######.com: [15/Dec/2007:02:52:43 +0000] 87.118.120.23 - - "GET / HTTP/1.0" 200 21466 [url] (compatible; MSIE 6.0; Windows NT 5.2; Win64; AMD64)"
As this is only a GET, I'm not sure what the purpose of this really was.
Also I seem to be getting loads of these recently:
Code:
shop.######.com: [17/Dec/2007:08:21:41 +0000] 82.19.60.98 - - "GET /_vti_bin/index.php?main_page=page_not_found HTTP/1.1" 301 5 "-" "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; InfoPath.1)"
Which I read is an automated hacker-bot checking for an unpatched MS server.
So my question is this;
What's the most effective thing we (as webmasters/hosts) can do to combat and report this sort of thing so we fight back against what's likely to be related to organised crime?

I have a dedicated box with Fasthosts and they tell me they've detected that the server is talking out to other networks via IRC although there's no activity on port 53.
Can anyone point me in the right direction of steps to take to find out what this is and eliminate it?
Recent changes to server include...
Started SpamAssassin (with network checks on - could these be the cause?)
Installed Mongrel as a proxy server for RoR apps and configured Apache on port 80 to make use of two Mongrel processes.
Some other data about server as requested on sticky thread on this board:
Linux OS: Fedora Core 6

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 just setup an instance of Apache on Windows with SSL and it starts by running "httpd.exe", but I can't get it to start as a service. It was running fine before adding the SSL certificate/key pair.
This is the error, I get as a Service:

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 have WHM 11.15.0 cPanel 11.17.0-R19429
FEDORA 4 i686 on standard - WHM X v3.1.0
/var keeps getting filled up with munin logs. Do I really need these logs? The server already had munin when I got it so I don't know how it was installed.
Can I disable it? I looked at the cron tab, and I don't see munin, but when I did chkconfig --list I found:
munin-node 0: off 1: off 2: on 3: on 4: on 5: on 6: off (spaces added because it made smileys)
How do I disable it?

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?
