Please release these notes before reporting any bugs to Bugdatabase. Thanks.

The following scripts are included in this release. For a detailed description please have a look at the usage informations of the scripts.

* check_groupshield
Checks the update status of the engine, the dat version and the antispam engine/dat files of the McAfee GroupShield 6.x for Exchange 200x.
* check_ipconfig
Make sure all required ip addresses and correct subnet masks are configured on the correct interface
* check_mscluster
This script can check the normal healthy status of a Microsoft(TM) Windows cluster. It can also check the status of several resource or groups.
* check_netshares
Make sure, the machine offerts all requested NetBios shares. This script does not validate the ACL permissions yet.
* check_onlineupdates/inspect_onlineupdates
The inspect_onlineupdates script search for new available Windows online updates and store them into a database. (Run this script from task scheduler regularly). The corresponding check script evaluate the database and alert if updates are pending or a reboot is required.
* check_perfcounter
To monitor performance counters on a machine this script can be used. It query the specified performance counter and alter if a value is to high.
* check_printers
Check the status of all printers on a Windows printserver. Can alert if a printer has a non-healthy state or if the queue contains too much print jobs.
* check_processes
Alerts if a process is not running, too much process, too little processes and so on. The syntax of the tests is stolen from the Unix test(1) command.
* check_service
Make sure all automatic services are running. Or if special services are specified, this script checks if they are running.
* check_shadowcopy
Count the created snapshots of a volume and alters if not enough snapshots are created; or if the last created snapshot is to old.
* check_taskscheduler
Reports errors if a scheduled task has not been started yet, or the task returns wich an non-success value.
* check_tcp
This is a simple clone of the check_tcp script from the Nagios plugin package which runs under windows which a compiler. Not all options are supported yet.
* check_uptime
Make sure the system is not in safe-mode. Alerts if the uptime is lower then a specified time and if the system was rebooted unexepectedly (system log).
* check_virusscan
This is the counter part of the check_groupshield script, but I checks the update status of a McAfee AntiVirus 8.5i installation: Engine, Dat.
* check_memory
Checks the free or used memory on a Windows machine.
* check_pagefile
Checks the pagefile usage on a Windows machines.
* check_processor
Check the CPU load on a Windows machine (at the moment no loadaverage is supported)
* check_win_disk
Checks the free or used space on a Windows volume. (The values can be percent or byte units)

Its caused by a limit on the OS. To find out your OS limit type:

# ulimit -n

To check how many open files a process may have find out its PID and type:

# lsof -p XXX | wc -l

The solution is:

# vim /etc/security/limits.conf

Add
* soft nofile 2048
* hard nofile 2048

(yes also the *)

Now restart sysctl:

# sysctl -p

Logoff and logon and check it now

#ulimit -a

Hope this helps.

More information

I have also done the same for a linux server. Just exec.:
netstat -anp | grep -c EST
In fact that script is only 2 lines:
result=`netstat -anp | grep :81 | grep -c EST`
echo “Conexoes Totais = $result |Conexoes=$result”
Note that | will graph that result, witch is very usefull!

There are many ways of getting that information, I have also
done the same thing via WMI, perfmon has that counter
and it maybe easier to for example find out the total number of
current connections to a specific website.

The script for windows is a .vbs and I call it using NC_NET
it can be downloaded here.

It is inspired by Nagios Checker for Firefox – I just did not want to have an open Firefox window all the time to monitor our network.

Nagstamon is released under the GPLv2 and free to use and modify.

Nagstamon is written in Python so it is highly portable. It has been tested successfully on Ubuntu 8.04 – 10.04, Centos 5.2 – 5.4, Fedora 8 – 12, OpenSUSE 11.0, Windows 2000 + XP + XP 64bit + Vista + Windows 7 + Windows 2008 Server, OpenSolaris 2009.06 and NetBSD.
It works with GNOME, KDE and Windows desktop.

Currently I monitor those server using

hit/ratio – official varnish nagios plugin witch is very basic, just returns me the hit/ratio witch is usefull but it does not output perfdata so no graphs for that.
conections – simple bash script that checks how many connections
are established. Simple like that:
result=`netstat -anp | grep :81 | grep -c EST`
echo “Conexoes Totais = $result |Conexoes=$result”
Load/Disk/Memory – are also standard plugins
Check_Backend – this one was a bit more complicated to develop and I find it very usefull, because it checks how many erros it got from the backend (like 503 etc…) I do that every 5 min, the script genertates a tmp file and then each time it runs it zero the tmp and restart loging the “Service Unavailable” erros thrown by “varnishlog -I Unavailable”
Here is the script

This is how my centreon monitor looks:

Idea of another scripts/monitors:
check_health_iis.sh
use the command:
# varnishadm debug.health |grep Sick

A sysadmin unpacked the server for this website from its box, installed an operating system, patched it for security, made sure the power and air conditioning was working in the server room, monitored it for stability, set up the software, and kept backups in case anything went wrong. All to serve this webpage.

A sysadmin installed the routers, laid the cables, configured the networks, set up the firewalls, and watched and guided the traffic for each hop of the network that runs over copper, fiber optic glass, and even the air itself to bring the Internet to your computer. All to make sure the webpage found its way from the server to your computer.

A sysadmin makes sure your network connection is safe, secure, open, and working. A sysadmin makes sure your computer is working in a healthy way on a healthy network. A sysadmin takes backups to guard against disaster both human and otherwise, holds the gates against security threats and crackers, and keeps the printers going no matter how many copies of the tax code someone from Accounting prints out.

A sysadmin worries about spam, viruses, spyware, but also power outages, fires and floods.

When the email server goes down at 2 AM on a Sunday, your sysadmin is paged, wakes up, and goes to work.

A sysadmin is a professional, who plans, worries, hacks, fixes, pushes, advocates, protects and creates good computer networks, to get you your data, to help you do work — to bring the potential of computing ever closer to reality.

So if you can read this, thank your sysadmin — and know he or she is only one of dozens or possibly hundreds whose work brings you the email from your aunt on the West Coast, the instant message from your son at college, the free phone call from the friend in Australia, and this webpage.

My site overall increase is very very little, and just now they are complaning, why?

So sorry everyone if you are having problems downloading files or
any thing else on the site. I am trying to solve the problem in the
best way possible.
