How to monitor NIC Traffic Load on FreeBSD 6.1

[overrider]

Hello all,

i would like to use the netloadin15[eth0] Item on my FreeBSD Server. However, my interface is not eth0 , but vrl0. Simply renaming the Item to reflecct my device just results in a Not Supported Message in the Trigger Status View. Any ideas?

Thanks,

[DiedX]

which version of server and client do you use?

[overrider]

freebsd 6.1 and zabbix-1.1.1

eth0 Is for Linux.
I do simply. I set a rule

ipfw count in me out !me via re0

which then and I process by means of zabbix_agentd.conf.

[overrider]

oh i thought one could just change the name of the nic somewhere.

[overrider]

can someone shed some more light on this? i would really like to get my zabbix to produce graphs for freebsd. my firewall in use is pf.

particularly i am interested that once i have such a rule as described above, how can i process it from withing zabbix_agentd.conf?

thanks and best regards,
overrider

Hi,

until we get Zabbix to support all those nifty net. items, here is what i did to monitor Bandwidth on FreeBSD with Zabbix, without needing to setup SNMP.

1. vi /usr/local/bin/bwpoll_in.sh
2. Copy and paste below into the File and save it

#!/bin/sh
/usr/bin/netstat -I fxp0 -b -f inet | grep fxp0 | awk '{print $7}'

3. vi /usr/local/bin/bwpoll_out.sh
4. Copy and paste below into the File and save it

#!/bin/sh
/usr/bin/netstat -I fxp0 -b -f inet | grep fxp0 | awk '{print $10}'

5. chmod +x /usr/local/bin/bwpoll*
6. vi /usr/local/bin/zabbix/zabbix_agentd.conf
7. append these two lines to the end of the file and save it

UserParameter=netfxp0in,/bin/sh /usr/local/bin/bwpoll_in.sh
UserParameter=netfxp0out,/bin/sh /usr/local/bin/bwpoll_out.sh

8. /usr/local/etc/rc.d/zabbix_agentd restart
9. Login to your Zabbix Webinterface
10. Create a new Item which looks like this
Describtion: NIC Load IN
Type: Zabbix Agent
Key: netfxp0in
Type of Information: Numeric Float
Units: bps
Use multiplier: Do not use
Update interval (in sec): 60
Keep history (in days): 7
Keep trends (in days): 90
Status: Monitored
Store Value: Delta(Speed per second)

11. Create a new Item which looks like this
Describtion: NIC Load OUT
Type: Zabbix Agent
Key: netfxp0out
Type of Information: Numeric Float
Units: bps
Use multiplier: Do not use
Update interval (in sec): 60
Keep history (in days): 7
Keep trends (in days): 90
Status: Monitored
Store Value: Delta(Speed per second)

Note that wherever it says fxp0, you must change this to the Name of the NIC you want to monitor. Get the info using ifconfig.

I you find an error or a better way to do this, please let me know.
