The Dude is a Monitoring application by MikroTik, which can dramatically improve the way you manage/monitor your network environment. It will automatically scan all devices within specified subnets, Draw and Layout a map of your networks, monitor services of your devices and execute actions based on device state changes.

Mikrotik's "The DUDE" LIVE Monitoring System , It shows Live View of all devices and server's on screen, Auto Refreshes at defined intervals,

GREEN icon shows target is Active & Healthy,
ORANGE shows one or more probes failed to poll query any specific counter/oid,
RED means the target device is not reachable via network or powered off.

With some my of my Customized Advance Monitoring Probes Like UPS Temperature, KESC Voltages IN , NOC Room Temperature, HDD Monitor, I have also made some Custom Alerts, For Example if NOC Room Temperature Goes bove 25 Degree, It will show Visual Alert, Email or SMS. or if D: drive space on mail server goes above 80% it will alert me, If a targeted service on specific server stop, it visually alerts. Voice Speak Alert for various counters. Very good and advance Monitoring System, It can Shutdown and POWER ON any system on MAP using tools and custom scripts, Also I have added some customize tools/scripts to run on target device using custom command , added in tool menu.

We call it CNMS, Centralized Network Monitoring System .

Make a list of devices to monitor:

Make sure no firewall or IPS system is blocking you on the network.

Make an priority on the hosts eq. host high, medium, low impact

Note the neighbors on the network for that host so that if a switch fails the admin is not overpowered with all the networks behind that switch. Keep in mind when you change the network config

Keep in mind the bandwidth usage

After installation make the services available within the dude according to the used services by inventory

After installation make the device types based on the above credentials per host

You can Install the DUDE on your Windows PC , OR you can also install it on your Mikrotik x86/RouterBoard.

First Download 'The Dude' from http://www.mikrotik.com/thedude.php

For Windows PC, Get the The Dude for Windows http://download.mikrotik.com/dude-install-3.6.exe

After download simply execute the .exe file and it will install it just like any other simple application.If you have install it on PC, you can start by going to START / Programs / The due.

For Mikrotik ROUTERBOARD (Hardware Version), First Get the NPK package, Download the .npk package for mikrotik, http://download.mikrotik.com/dude-3.6.npk (Note: Select the ver accordingly.)

After downloading .npk, upload it to Mikrotik Files section and reboot the Mikrotik, It will automatically add the The Dude package in it before rebooting. Follow the image below.

After installation, Both management is done in a same manner. You access the DUDE installed on Mikrotik by using your windows base dude to connect to mikrotik.

If you are running the DUDE on PC, you can start by going to START / Programs / The due

If you are running the DUDE on Mikrotik, first install the dude on your windows pc, then using it, you can connect to Mirkotik's dude. Same as you use Winbox to connect to any Mikrotik. You can use the dude on your windows to connect to any dude all over the network.

Ok execute the dude. You will be asked for the credentials, Just like Mikrotik default installation, dude have no default password,

Now you will The Dude main screen. Just for an example, I will add simple Network by using Auto DISCOVERY. You can later create your own desired network MAP once you understand HOW things works in dude.

Use your local subnet series. Also click on 'LAYOUT MAP AFTER DISCOVERY COMPLETE'.

Remove un-necessary services from SERVICES menu, so you will not get red icon if the services not found.

Its best to install SNMP on all of your servers to get the maximum information like Link usage/CPU/Memory/HDD etc etc.

After it will completes the discovery, it will create a automatic layout map, Something similar to below image

If you are unable to see any PC , Try adding few ips manually. If target pc ping/icmp is blocked, then you won't be able to see any PC in the graphs, so its better to use another approach /combination on 'Device name preferences'. Also check your mikrotik / target pc firewall configuration.

The above image looks Pretty much messed up, but you can trim it or adjust it according to your flavor, like the example one below

Sometimes You would like to add only few targeted devices / computers on your network to be monitored via dude.

To do so follow the instructions showed in the below screenshots.

On the Network MAP screen, Click on + sign, then select Device. Now enter IP address of your target device and click NEXT.

Now select DISCOVER to check what services target device is offering for monitoring.

Now add another device as shown in above images.

Now add Network ICON so that we can connect both devices for link monitoring.

Now the real part, Again Click on + sign and click LINK to create link between device and network icon.

You can change background image by going to

You can also View/Controll Dude via web browser. This is convenient if you have fix public ip on your mikrotik / pc where due is hosted, you can monitor your network all over globe using browser only.

First you have to enable Web Service in DUDE.

Make sure there is no other web server running on your pc/mikrotik. If so, please change the port in above image to something different , example 1234. Now open your browser and point it to your dude server.

http://URL_of_Mikrotik:1234

It will ask id password, Enter your credentials. (First time dude installation have no password, just enter use admin without any password, and then you can change password from ADMIN section.

Now click on MAPS > Network Map & you will be redirected to your network map. See the below image.

If you want to monitor link bandwidth usage, and you want to configure that if the link is used fully its color should be changed as showed in the image below.

take properties of link , and tick on 'speed' and define the value you want to monitor. for example 1mb as showed in the image below.

Right click on your device and select APPEARANCE, click on LABEL: and add this OID (For example only, change the OID as your requirement)

NOC Room Temperature : [oid("1.3.6.1.4.1.534.1.6.5.0")]

Open Dude console, from left menu, goto tools, and click on plus sign + to add new tool,the following

Type: Executable

Name: Shutdown Target

Command: c:\windows\system32\shutdown.exe -s -f -t 30 /m \\[Device.FirstAddress]

To monitor C: or D: drive for space alert, First create Function, then create probe and use the function. then add this probe to device

Now create an new Function:

name: drivec

Code: if(array_size(oid_column("1.3.6.1.2.1.25.2.3.1.6",10,5)),round((oid("1.3.6.1.2.1.25.2.3.1.6.1",10,5)/oid("1.3.6.1.2.1.25.2.3.1.5.1",10,5))*100),"False")

Now create an new Probe.

Name:Low Space in C Drive

Type: Function

Available:drivec()<>"False"

Error:if(drivec()<>"False",if(drivec() < 85, "", concatenate("Warning: Drive C = ", drivec(), "%")), "Failed to read Drive C the server might be down")

Value:drivec()

Unit: %

Now add this probe in target windows device in service section. That's it. Now if the C: Drive goes above 85%, it will alert, you can tag voice/visual/email/sms alert with it. The OID for the C: drive can be different on your system , it depends on the drives you have in your system, for example I used the 1.3.6.1.2.1.25.2.3.1.6.1 , but you may have 1.3.6.1.2.1.25.2.3.1.6.2 , so its better to check it in snmp section of device properties.

You have to first install snmptools and add disk counters in the ini file in order to retrieve the disk read write time counters.e.g: http://aacable.wordpress.com/2012/07/25/using-snmptools-to-monitor-disk-read-write-time-win2008-6432-bit / Disk Read / Write Time C: & D: [string_substring(oid("1.3.6.1.4.1.15.1"),0,3)] / [string_substring(oid("1.3.6.1.4.1.15.2"),0,3)]

Create New Probe and tag it with your required target device.

Probe Name: lotus_notes_test

Type: Function

Available: if(array_find(oid_column("1.3.6.1.2.1.25.4.2.1.2"), "notes2.exe")>0, 1, -1)

Error: if(array_find(oid_column("1.3.6.1.2.1.25.4.2.1.2"), "notes2.exe")>0, "", "notes2.exe not detected by SNMP probe")Notes not running on zaib pc")

Value: 1

Unit: running

Note: Replace notes2.exe with your require files name you want to monitor. The name is case-sensitive! Write the file name the same as you see it in the Windows Task Manager List.

Create New Probe and tag it with your required target device.

Probe Name: check_telnet_service

Type: Function

Error: if(array_find(oid_column("1.3.6.1.4.1.77.1.2.3.1.1"),"Telnet")>0, "", "Telnet not detected by SNMP probe")Value: 1

Value: 1

Unit:

Note: Replace Telnet with the service name your want to monitor. Type the full name of the service you see in the services console. The name may be case-sensitive! Write the file name the same as you see it in the Services Console.

If you want to monitor specific OID result and if it gets below or above your pre-defined number, it should alert, Use the below probe (I used this probe to monitor my data center room temperature using temperature device, if the temperature goes above 25, it alerts)

Name: NCO Room Temperature Alert

Type: Function

Available: if(oid("1.3.6.1.4.1.534.1.6.5.0")>0, 1, -1)

Available: if(oid("1.3.6.1.4.1.534.1.6.5.0")<25, "", "NOC Room Temp Over 25, Turn ON Extra AC")

Value: 1.3.6.1.4.1.534.1.6.5.0

Unit: C

On device label, use the following oid [Make sure you have enabled the snmp on the printer and in the device snmp section)
