MIKROTIK DUDE BASIC INSTALLATION GUIDE, yes only basic ~ Article by Syed Jahanzaib ~

CNMS - Centralized Network Monitoring & Management System !!! - JZ

Example MAP of my Office LAN

What is THE DUDE ?Answer is below > As Mikrotik Wiki defines:

The Dude is a free Monitoring application by MikroTik, which can dramatically improve the way youmanage/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.

Some customized probes used in this map:

Mikrotik’s “The DUDE” LIVE Monitoring System , It shows Live View of all devices and server’s onscreen, 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 NOCRoom Temperature Goes above 25 Degree, It will show Visual Alert, Email or SMS. or if D: drive space onmail 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 MAPusing tools and custom scripts, Also I have added some customize tools/scripts to run on target deviceusing custom command , added in tool menu.

We call it CNMS, Centralized Network Monitoring SystemThanks to DUDE

You can Install the DUDE on your Windows PC , OR you can also install it on your Mikrotikx86/RouterBoard.

First Download ‘The Dude’ from

1 http://www.mikrotik.com/thedude.php

For Windows PC, Get the The Dude for Windows

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

For Mikrotik ROUTERBOARD (Hardware Version), FirstGet the NPK package,

Download the .npk package for mikrotik,

(Note: Select the ver accordingly.)

After downloading .npk, upload it to Mikrotik Files section and reboot the Mikrotik, It will automaticallyadd 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 onMikrotik 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, youcan connect to Mirkotik’s dude. Same as you use Winbox to connect to any Mikrotik. You can use thedude 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, dudehave no default password,ID = adminPassword = No Password, Just Enter

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 thingsworks 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 notfound.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 belowimage.

If you are unable to see any PC , Try adding few ips manually. If target pc ping/icmp is blocked, then youwon’t be able to see any PC in the graphs, so its be�er to use another approach /combination on “Devicename preferences”. Also check your mikrotik / target pc firewall configuration.

The above image looks Pre�y much messed up, but you can trim it or adjust it according to your flavor ,like the below

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.

Some of the examples are taken from the Mikrotik DUDE forum.Special thanks to Mr. Lebowski

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

OR

if you want to divide the value to be displayed, use following formula

HOWTO Remote Shutdown any PC using DUDE Tools

(generally for AD environment)

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

I will add more snaps and info of some live networks where I deployed this beautiful tool.

HOWTO add probe for disk like C: & D:

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 new Probe.

Now add this probe in target windows device in service section. That’s it. Now if the C: Drive goes above85%, it will alert, you can tag voice/visual/email/sms alert with it. I use VOICE alert NOTE: The OID for the C: drive can be different on your system , it depends on the drives you have inyour 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 itsbe�er to check it in snmp section of device properties.

:)

HOWTO show Disk Read & Write Time

You have to first install snmptools and add disk counters in the ini file in order to retrieve the disk readwrite time counters.e.g: h�ps://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)]

HOWTO check if specific program is running or not [using

taskmgr list]

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

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.

123456

Probe Name: lotus_notes_testType: FunctionAvailable: 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 detectedValue: 1Unit: running

HOWTO check if specific SERVICE is running or not

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

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

HOWTO Create Alert if specific OID result gets belowSpecific Digit/% like NOC room temperature

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

and if you want to divide the snmp result by 100 , then you have to first create function likefollowing.

123456

Probe Name: check_telnet_serviceType: FunctionAvailable: if(array_find(oid_column("1.3.6.1.4.1.77.1.2.3.1.1"),"Telnet")0, 1, 0)Error: if(array_find(oid_column("1.3.6.1.4.1.77.1.2.3.1.1"),"Telnet")0, "", "Telnet not detectedValue: 1Unit:

HOWTO show ping result on device label

If you want to show the ping result on your device label, Right click on device , select appearance, inLablel, paste the following code:

[array_element(ping(device_property(“FirstAddress”)),0)] ms

HOWTO Check for High Delay via Ping Function/Probe

If you want to monitor any device ping delay ms, for example if ping ms delay to any internet linkincreases above 600 ms , then it should alert, use the following function/probe.

First add new function

Now create probe and tag the ping_r� function in it.

Now tag it with the device in services section.

1234

Function:Name: ping_rttDescription: Returns the round-trip time of a ping request to the FirstAddres of a deviceCode: round(array_element(ping(device_property("FirstAddress")), 0))
