Installation may require multiple system reboots before launching IPSentry.

This operating system will be considered unsupported after January 1, 2007

Windows 98

Unsupported

Windows 95

Unsupported

Install it through the wizard, after done you should prompted by this:

Set the General Tab

Default action timeout should be > 30 to prevent service restart while you're editing it.

click Run as Service button to make it becomes windows service

enter your server server login credential then press install service.

after that you can begin your first system monitoring like this:

Select a monitoring mode which is match your device to be monitored.

Here is some example monitoring:

HTTP/s Enhanced Web Monitor

This type of monitoring allows you to monitor your webpage content (not just the availability of the http service)

Go type your website url in the URL box select your method as GET HEAD or POST. if you isn't familiar with this process, dont worry IPsentry had an predefined request already that can be used to check your website content. All you need is define what expect data should be match or no Match in return. eg: you can type a text that mostly appear in your website when your website is properly shown. When the text cannot be drew after ipsentry requesting HTTP request which is mean your website is not well shown (eg, script error/database error), it will triger the alert to you. Reporting that your website isn't OK or critacal.

NT Services Monitor.

With this type of monitoring, you can monitor your NT service whether it's running/stopped or not responding. the good thing is this monitor can monitor a remote device not just it self, all you need is provide the login credential to allow ipsentry logon to that machine and grabbing the services list.

You can explore its another function by yourself, mostly service are provided to windows environment. but if you want to monitor an linux box or other kind devices, dont worry ipsentry has provided a customizable monitoring with scripted tcp (monitor anything through TCP packet) or monitor via SNMP packets.

Scripted TCP/IP Network Monitor.

Actually Ipsentry didn't provide built in SSH port monitoring, you can do that with this kind of monitoring. all you need is create an TCP packet script. dont worry, various of famous service script is provided. You can open it and figure out how to create your own tcp script.

this is an example for FTP:

You can configure your return data, eg: if it didn't return with "250 CWD command Successful." it will triger the alert.

Sometimes, when an error occur and triger the alert that makes you realize an error happen to your system. you will begin investigate it and try to fix it. while you doing this alert still comes until it truly fixed. this will makes alerts flooding to you when the time to fix is too much longer. to prevent this happen you can use this feature:

SNMP packets Monitoring.

Many devices that generating SNMP packets can be monitoring with this.

Just enter your SNMP type, login credential (SNMP v3), snmp community acces.

The bad thing is ipsentry did not provide direct/defined famous snmp object to monitor (such as interface object) you should figuring out what kind snmp object do you want to monitor. ouch!

the gray object select is example to monitor interface speed (ifSpeed).

(An estimate of the interface's current bandwidth in bits per second. For interfaces which do not vary in bandwidth or for those where no accurate estimation can be made , this object should contain the nominal bandwidth.)

Not familiar with snmp yet? this link can be refered on how to install snmp on linux/unix box

Monitoring Suspend.

enter exactly in Days:Hours:Minutes eg. 00:02:00 (this will makes the alert stop coming for 2 hours) or you can leave it blank to suspend it indifinitly when suddenly you cannot fix the problem and need to assisted by somebody, Oughh!

Sometimes a network maintenance will makes all device to be stated as failur and off course pulling the triger on to start screaming! oughh..

to prevent this happen, there is an schedul down time editor like this:

Just enter the day that you wish the alert isn't screaming due to maintenance :)

when you have more than one departement you handle it, you can separate each other departement with dependencies. this will make easier to manage when each departement has different maintenance schedule

here is the example:

Just suspend / schedule downtime the parent entry. it will makes child nodes to be suspended too :)

Talking about alert, you might be wondering the way you received the alerts.

Ipsentry can triger the alert and then pulling it to play audible or send message via pager/cell, email,sms, launch an aplication or turning off your devices.

This is the example for alerting through Email

You can enter your brief message in there with variable that already predefined by ipsentry or created by your self.

Overall, Ipsentry is good to be choosen as your monitoring software suite.its worth to spend your money to buy this software just likely other payware, it comes with complete service and updates. But if you decide to spend nothing to monitor your network, there is any other software available for free. I'll write it soon :D

Thats all folks :D you can now monitor all your network and devices to gain performance and decrease connectivity problems.
