[How To] Graphing Simple Queue Using Cacti

 by tjdykb » Sun Feb 11, 2007 1:03 pm

I've searched the forum and the internet for tutorial on how to capture Router OS's simple queue OID using cacti, and haven't find any luck.. 

So I decided to share my really simple way, by capturing each OID manually for every entry in Simple Queue I want to graph.. 

Please notice that I am not an expert in whether Cacti or Mikrotik Router OS, so It will be great if you guys willing to show me/us a better way to do this.. 

Why cacti? why not built-in graphing tools provided by Router OS?..., for now I only have one reason --> With cacti we could gather data from spesific range of time.. 

This How-to assumed that you already have knowledge on installing and using cacti... 

Also notice that Router OS Simple Queue OID will be dynamically changed if we delete (-) entry on our queue.. 

To find out the OID of the simple queue we want to graph (from the router OS)... 

Code: Select all

[tjdykb@xxx] > /queue simple pr oid 

You will find entries like

Code: Select all

Flags: X - disabled, I - invalid, D - dynamic
 0    name=.1.3.6.1.4.1.14988.1.1.2.1.1.2.54
      bytes-in=.1.3.6.1.4.1.14988.1.1.2.1.1.8.54
      bytes-out=.1.3.6.1.4.1.14988.1.1.2.1.1.9.54
      packets-in=.1.3.6.1.4.1.14988.1.1.2.1.1.10.54
      packets-out=.1.3.6.1.4.1.14988.1.1.2.1.1.11.54

 1    name=.1.3.6.1.4.1.14988.1.1.2.1.1.2.32
      bytes-in=.1.3.6.1.4.1.14988.1.1.2.1.1.8.32
      bytes-out=.1.3.6.1.4.1.14988.1.1.2.1.1.9.32
      packets-in=.1.3.6.1.4.1.14988.1.1.2.1.1.10.32
      packets-out=.1.3.6.1.4.1.14988.1.1.2.1.1.11.32

 2    name=.1.3.6.1.4.1.14988.1.1.2.1.1.2.1
      bytes-in=.1.3.6.1.4.1.14988.1.1.2.1.1.8.1
      bytes-out=.1.3.6.1.4.1.14988.1.1.2.1.1.9.1
      packets-in=.1.3.6.1.4.1.14988.1.1.2.1.1.10.1
      packets-out=.1.3.6.1.4.1.14988.1.1.2.1.1.11.1

etc.. 


Watch the ID of the simple queue we want to graph .. the entry we use is bytes-in (download) OID and bytes-out (upload) OID.. 

What I did (in cacti) was made a data template (duplicated from SNMP - Generic OID Template) one for download and one for upload each, so we will have two data templates, which we will use to capture 2 different OID from one simple queue entry.. The template file link available at the end of this message ... I also made a graph Template .. modified from SNMP Interface Template.. (link also available).. 

Then I made data-sources for Download Traffic and Upload Traffic using the previously imported/made data-templates (say MT-SQ-down and MT-SQ-up) .. for Download Traffic put the OID bytes-in you get from the Router OS and bytes-out for Upload Traffic.. 

Finally we made the simple queue graph for Router OS Device, using the graph template imported/made before.. choose Download and Upload Traffic for data-sources 

Wait for 10 whoe minutes .. 

I know it rather stupid, but at least there is a way ..  
Good Luck
