Editing SNMP trap frequency in ESXi 5.0

Hi, we're currently getting a lot of these messages from our ESXi hosts since turning on SNMP traps -

vmware.vmwProductSpecific.30.3.0

I've scoured the vmware forums and it looks like we need to edit the file /etc/sfcb/sfcb.cfg. However I'm unable to get to that file through SSH. It tells me access is denied. So I tried installing the vCLI but i can't work out how to connect to the ESXi host in order to edit the file.

Is there anyone that's able to help?

Many thanks in advance.

We're using the licensed version.
I found that page earlier but can't work out how you connect to a server in order to run the edit command at the bottom. Any ideas?

Everything has been setup as per the link you sent but i was wondering if there's a way to change the frequency of the traps.

I found the below but can't work out where to enter the command in the first place!

Edit /etc/sfcb/sfcb.cfg
add
heartbeatInterval: <seconds>

you need to login to the server via the console or ssh (remotely).

and use vi

e.g

vi /etc/sfcb/sfcb.cfg

if you do not know of to use vi, you can use WinSCP from Windows.

Ok, I've entered that line into the sfcb.cfg file using vi through SSH but it doesn't seem to make any difference.

To test I set the interval time to 30 seconds but they still come every 5 minutes. I've disabled and reenabled the SNMP agent too.

Is there another setting somewhere?

Thanks

did you restart the host?

No. I did this -

vicfg-snmp.pl --server <hostname> --username <username> --password <password> --disable
Enabling agent...
Complete.

vicfg-snmp.pl --server <hostname> --username <username> --password <password> --enable
Enabling agent...
Complete.

Is that not enough? Does the heartbeatInterval line need to be put anywhere in particular within the sfcb file? That's all i can think it'd be.

other than editing the file is not supported, as long as it's in the file.

It's strange because no matter what value i put into the line it seems to ignore it. Do you think i need to restart the whole host in order for it to take effect? Seems a bit drastic!

At a convenient time, I would certainly try restarting the host.

Unfortunately finding a convenient time to restart the host is going to be pretty hard to do. Are there any other suggestions out there?

Thanks
