How to check SWITCH is alive

[Handi]

hi all.
I'm just trying to use zabbix. I want to know how to find out the status of the SWITCH, whether he's alive or dead??

I use the SWITCH AT-8500
SNMP v2

Depends on how you define dead and alive.

I assume there are OIDs telling you whether ports are up or down.

And you can create a data with .nodata() to make sure device is answering SNMP queries.

How did you apply nodata() with SNMP?

[Handi]

I mean how to know a switch is alive or dead, not the ports of the switch is.

[Calimero]

ping ?
monitoring whether it responds to SNMP queries (as I said above) ?

You define what "dead" is and then tell zabbix how to monitor it.

If you aren't specific, don't expect a definitive answer.

[Handi]

for the example in monitoring PC
{HOSTNAME} is unreachable
can cause:
- power is switch off
- UTP cable is unplug

{HOSTNAME} is unreachable

Well it's the other way around, power off or network down may trigger "server is unreachable".

Maybe you should try monitoring response to ICMP ping ? Is that what you want ?

I've tried using icmpping.
configure
item
create items
but why the status "not Suported

[Calimero]

Did you set item type to "Simple check" ?

[Handi]

yes of course...

but in the error column value:

"/usr/sbin/fping: [2] No such file or directory"

[Calimero]

Mhh... did you install fping in the first place ?
Did you set FpingLocation= in zabbix_server.conf ?

[Handi]

yes i did
after work, the value of icmping never change always 0

[Calimero]

Mhh ... can you show us what perms fping has ?

ls -l /usr/sbin/fping

[Handi]

-rwxr-xr-x 1 root root 26322 2009-09-01

[Handi]

But now I was change to

-rwxrwxrwx 1 zabbix zabbix 26332

but is not work too

-rwxrwxrwx 1 zabbix zabbix 26332

fping must be setuid root.

chown root:root /usr/sbin/fping
chmod 4755 /usr/sbin/fping
