XI 2014 R2.7.
Network Switch / Router Wizard v 2.1.7

I ran the Switch / Router wizard against the device WAP01 <--- note the upper case name
XI host can correctly resolve this dns name so I chose it instead of the IP Address
I gave it the hostname "D-Link DAP-2310 - WAP01" ... but that isnt' relevant.
Wizard completed fine.
MRTG conf file was created: WAP01.cfg
Correct target names in config file:

Code: Select all

Target[WAP01_1]: 1:somethingsecure@WAP01:161::::2

Uppercase files are not being created in /var/lib/mrtg/ BUT lowercase ones are:

Code: Select all

ls /var/lib/mrtg/WAP*.*
ls: cannot access /var/lib/mrtg/WAP*.*: No such file or directory

ls /var/lib/mrtg/wap*.*
/var/lib/mrtg/wap01_2.rrd  /var/lib/mrtg/wap01_5.rrd  /var/lib/mrtg/wap01_7.rrd
/var/lib/mrtg/wap01_4.rrd  /var/lib/mrtg/wap01_6.rrd

Which causes the services to fail with:

Code: Select all

/var/lib/mrtg/WAP01_6.rrd does not exist.

Code: Select all

define service {
	host_name			D-Link DAP-2310 - WAP01
	service_description		ath0 Bandwidth
	use				xiwizard_switch_port_bandwidth_service
	check_command			check_xi_service_mrtgtraf!WAP01_6.rrd!150,150!240,240!M
	max_check_attempts		5
	check_interval			5
	retry_interval			1
	check_period			xi_timeperiod_24x7
	notification_interval		60
	notification_period		xi_timeperiod_24x7
	contacts			nagiosadmin
	_xiwizard			switch
	register			1
	}

Code: Select all

define host {
	host_name			D-Link DAP-2310 - WAP01
	use				xiwizard_switch_host
	address				WAP01
	max_check_attempts		5
	check_interval			5
	retry_interval			1
	check_period			xi_timeperiod_24x7
	contacts			nagiosadmin
	notification_interval		60
	notification_period		xi_timeperiod_24x7
	icon_image			switch.png
	statusmap_image			switch.png
	_xiwizard			switch
	register			1
	}

So it seems that MRTG always dumps the files in /var/lib/mrtg/ as LOWERcase files.

So either there is a flag for MRTG to stop this from happening OR the switch wizard needs to convert the following to lowercase:

The address when cfgmaker is run
The check_command for the service which points to the specific RRD file
