MRTGWebCfg: How to add new host, step by step

 

The following steps are required for adding a host:

 

Step 1: Host creation

Go to Control Panel and navigate to IP Address Management, next choose Add an IP address

Fields IP Address, Description and Password are mandatory

 

For instance:

IP Address - 127.0.0.1

Description - My HOST

Password - public

 

Step 2: Basic setup

Go to Control Panel, then choose Add Record and and create Basic settings for MRTG.

 

Select the host created in 1st step (match by ip field).

 

Specify title specify how to name new setting (For instance: Traffic Analysis for fxp0 on localhost)

 

ver_snmp - SNMP protocol version (for instance: 1 or 2)

 

filename - RRD file name, where MRTG data stores collected data (For instance: traffic_fxp0_localhost)

 

target - SNMP OID

OID values are standardized for most equipment and can be browsed by any SNMP browser.

For instance: The first server NIC defines the following OIDs:

 

1.3.6.1.2.1.2.2.1.1 à ifIndex -> Interface identifier

1.3.6.1.2.1.2.2.1.10 à ifInOctets -> Packets count

1.3.6.1.2.1.2.2.1.16 à ifOutOctets -> Number of packets sent

1.3.6.1.2.1.2.2.1.14.1 à ifInErrors -> Errors rate in incoming flow

1.3.6.1.2.1.2.2.1.20.1 à ifInErrors -> Errors rate in outgoing flow

 

Red digit states for interface number.

 

In general Targer filed is determined by MRTG configuration, it is supposed that SNMP and MRTG things are known for You. Target field is assembled as the following:

 

SNMP v1:

 

Target["filename"]: target:Password@IP Address

 

For instance:

Target["traffic_fxp0_localhost"]: .1.3.6.1.2.1.2.2.1.10&.1.3.6.1.2.1.2.2.1.16:public@127.0.0.1

or

Target["traffic_fxp0_localhost "]: .1.3.6.1.2.1.2.2.1.14.1&.1.3.6.1.2.1.2.2.1.20.1:public@127.0.0.1

 


For SNMP v2:

 

Target["filename"]: target:Password@IP Address :::::2

 

For instance:

Target["traffic_fxp0_localhost"]: .1.3.6.1.2.1.2.2.1.10&.1.3.6.1.2.1.2.2.1.16:public@127.0.0.1 :::::2

or

Target["traffic_fxp0_localhost "]: .1.3.6.1.2.1.2.2.1.14.1&.1.3.6.1.2.1.2.2.1.20.1:public@127.0.0.1 :::::2

 

Parameters interface_ip and interface_name describe the following MRTG things:

 

SetEnv["filename"]: MRTG_INT_IP="interface_ip" MRTG_INT_DESCR="interface_name"

 

For instance:

 

SetEnv["traffic_fxp0_localhost"]: MRTG_INT_IP="127.0.0.1" MRTG_INT_DESCR="fxp0"

 

The rest of the parameters on Adding record page are the same as MRTG parameters. They are maxbytes, iftype, absmax, withpeak, options, colours, ylegend, shortlegend and others.

 

Step 3: Template management, placing graphic at the page.

 

Placing graphic on MRTGWebCfg is the next thing to do after the Basic settings.

 

Graphic information is organized by groups. The Default group always exists and new objects are placed in that group. Also Default group is displayed on the first page of MRTGWebCfg.

Groups are managed in Group Management

 

Next go to Template Management

Templates can be created manually by choosing proper basic settings and specifying group and page place (row and column). Also Template management - GUI can be used.

 

MRTG configuration file may be created after the 2nd step.

3rd step is only required for proper placing graphic on MRTGWebCfg page
